2. Literature Review
The concept of decent work, as identified by the International Labour Organization (ILO) [
13], encompasses four pillars: employment creation, social protection, rights at work, and social dialogue. It emphasizes the following aspects:
Provision of productive work opportunities that ensure fair income.
Establishment of secure workplaces and social protection for families.
Enhancement of personal development prospects and social integration.
Freedom to express concerns, organize, and participate in decisions affecting individuals’ lives.
Guarantee of equality of opportunity and treatment for both men and women.
Decent work in the tourism sector has been a topic of study, and empirical research reveals a mixed perception of the quality of work, working conditions, and practices from a “decent work” perspective [
12,
14,
15].
Several issues arise within the tourism workplace, as highlighted in the literature:
Extended working hours and low wages [
10,
20,
21];
Limited social protection [
22,
23,
24];
Inadequate working schedules, insecure employment contracts, overwork, insufficient pay, lack of progression opportunities, missed mealtimes, wage disputes, low recognition of trade unions, income insecurity, split shifts, unpaid overtime, physical violence, sexual harassment, and stress [
25,
29,
30,
31].
Moreover, studies have identified further issues, such as lack of respect and recognition, limited workplace autonomy, monotonous tasks, poor communication, inadequate fixtures and fittings, issues related to people’s identity at work, sexualized labour, sex tourism, racism, and seasonality [
32,
33,
34,
35,
36].
Decent work extends beyond job creation and emphasizes the quality of employment [
13]. Therefore, this study argues that workplace dignity is positively correlated with corporate social sustainability. In other words, social sustainability relies on firms providing decent working conditions.
Socially sustainable tourism firms can contribute to several Sustainable Development Goals (SDGs):
SDG 1: No Poverty—Tourism firms can contribute to poverty reduction by creating employment opportunities, particularly for marginalized groups, and generating income and economic benefits for local communities.
SDG 3: Good Health and Well-being—Tourism firms can support the development of healthcare infrastructure and services at destinations, improving access to quality healthcare for both residents and visitors.
SDG 4: Quality Education—Tourism firms can contribute to enhancing educational opportunities and promoting lifelong learning by supporting educational initiatives, training programs, and cultural exchange.
SDG 5: Gender Equality—Tourism firms can promote gender equality by empowering women and girls through employment, entrepreneurship, and leadership opportunities, as well as by challenging gender stereotypes and promoting equal rights and access to resources.
SDG 8: Decent Work and Economic Growth—Tourism firms have the potential to create decent and inclusive employment opportunities, improve working conditions, and foster sustainable economic growth, thus contributing to poverty reduction and social well-being.
SDG 10: Reduced Inequalities—Tourism firms can help reduce inequalities by promoting social inclusion, providing equal opportunities for all, and ensuring that the benefits of tourism are distributed fairly among different social groups and regions.
SDG 11: Sustainable Cities and Communities—Tourism firms can contribute to creating sustainable and resilient cities and communities by preserving cultural heritage, improving infrastructure, supporting local businesses, and enhancing the quality of life of residents.
SDG 16: Peace, Justice, and Strong Institutions—Tourism firms can promote peaceful and inclusive societies by fostering cultural understanding, intercultural dialogue, and respect for diversity, thus contributing to social cohesion and peaceful coexistence.
These aspects emphasize the importance of ensuring that tourism activities are sustainable, inclusive, and beneficial for local communities, while also respecting human rights, promoting cultural heritage, and contributing to social well-being.
The SDGs offer a set of specific targets and indicators such as employment rates, poverty rates, education levels, gender equality indices, and access to healthcare that have been used to evaluate the social impact of tourism on local communities.
In
Table 1, we categorize corporate social sustainability indicators found in the literature into eight dimensions: physical working conditions, wages, career development, health, community, clients, competitors, and the economy. These indicators vary in terms of the control that business decision-makers have over them, the effort required for their incorporation into decision-making processes, and the financial burden associated with their implementation [
37]. However, it is important to note that quantitative indicators represent only a portion of the proposed indicators, as obtaining data for some indicators can be challenging [
38,
39,
40,
41,
42].
Drawing on stakeholder and legitimacy theories, firms recognize that maintaining good relationships with stakeholders can enhance their social sustainability by developing and preserving intangible assets [
44]. Furthermore, workplace benefits, such as improved health and safety conditions, can motivate employees, foster loyalty, reduce recruitment and training costs, and increase productivity [
45,
46]. Socially sustainable practices can also contribute to a firm’s sustainable competitive advantage by enhancing reputation and consumer trust in brand value [
47,
48].
The study by Labuschagne et al. [
49] is the first to develop a social sustainability performance index for manufacturing firms in South Africa. It proposes four main pillars of social sustainability: internal human resources practices, external population, stakeholder participation, and macro-social performance.
Table 1 presents social sustainability indicators derived from the literature, categorized from the stakeholders’ perspective into various dimensions [
50].
Furthermore, the behaviour of suppliers can influence the social sustainability performance of the purchasing organization [
51]. Notably, companies like Nike and Apple have faced damage to their reputation due to child labour practices employed by their suppliers [
52].
Business activities involve and impact various stakeholders, thereby influencing their decision-making processes [
53].
The social dimension of tourism has been studied in the context of community perceptions and engagement. For example, da Silva et al. [
54] conducted a study on socially sustainable tourism in cities, focusing on local community perceptions and development guidelines. The findings provided insights into the perceptions of the local community regarding the social sustainability of tourism and proposed guidelines for promoting socially sustainable tourism in urban areas. Moreover, Dans and González [
55] conducted a study on sustainable tourism and social value at World Heritage Sites, using Altamira in Spain as a case study. The study explored the social value of World Heritage Sites and proposed a conservation plan to enhance the social sustainability of tourism in Altamira, Spain. Moreover, Jover and Díaz-Parra [
56] examined the intersections of overtourism, lifestyle migration, and social sustainability in the context of cities. The study explored the social implications of overtourism and lifestyle migration, discussing the challenges and opportunities for achieving social sustainability in urban tourist destinations. In addition, Torkington et al. [
57] analyzed national tourism policy documents to explore the discourse of growth and sustainability within these documents. The study highlighted the different discourses surrounding growth and sustainability in national tourism policies and identified potential tensions and challenges in achieving sustainable tourism development.
Another stream of literature focuses on the challenges posed by COVID-19. Indeed, Almeida and Silva [
58] examined the impact of the COVID-19 pandemic on tourism sustainability in Portugal. The study provided evidence of the pandemic’s effects on various aspects of tourism sustainability, including environmental, social, and economic dimensions. Higgins-Desbiolles [
59] explored the socialization of tourism for social and ecological justice after COVID-19. The study discussed the potential for reimagining tourism in a way that prioritizes social and ecological sustainability in the post-pandemic era.
A third line of research is Tourism Planning and Policies. In this framework, Benner [
60] focused on the transition from overtourism to sustainability in the Adriatic region. The study proposed a research agenda for qualitative tourism development, highlighting the need for sustainable approaches to address overtourism challenges and promote sustainable tourism in the region. In addition, Pato and Duque [
61] conducted an analysis of national strategic plans in Portuguese tourism since 2000. The study identified strategic issues and priorities in these plans and shed light on the evolution of tourism planning in Portugal and its implications for sustainability.
Some authors highlight the role of entrepreneurship in sustainable tourism. Bakas et al. [
62] focused on small-scale art festivals with creative tourism in Portugal and explored their social utility. The study highlighted the social benefits and impacts of small-scale art festivals and emphasized their contribution to community development and cultural sustainability. Duarte et al. [
63] investigated lifestyle entrepreneurship as a vehicle for leisure and sustainable tourism. The study explored the relationship between lifestyle entrepreneurship, leisure activities, and sustainable tourism and emphasized the potential for lifestyle entrepreneurship to contribute to sustainable tourism development.
Another view of socially sustainable tourism concentrates on sustainable practices and implementation. A notable example is the study by Higgins-Desbiolles et al. [
64], in which the authors discussed degrowing tourism and the need to rethink tourism for social and ecological justice. The study examined the concept of degrowth and its implications for transforming tourism into a more socially and ecologically just system. Khatter et al. [
65] analyzed the environmentally sustainable policies and practices of hotels, focusing on sustainability and corporate social responsibility in the hospitality and tourism industries. The study examined the adoption of sustainable practices by hotels and identified opportunities to enhance sustainability and corporate social responsibility in the sector. Pereira et al. [
66] conducted a case study of a luxury hotel in Arrábida Natural Park, Portugal, and examined sustainability practices in hospitality. The study highlighted specific sustainability practices implemented by the hotel and provided insights into how sustainability can be integrated into the operations of the hospitality industry. Social impacts and quality of life have been researched by Ramkissoon [
67], who developed a conceptual model of the perceived social impacts of tourism and quality of life. The study explored the relationship between the impacts of tourism and residents’ quality of life, emphasizing the importance of understanding and managing the social aspects of tourism development. Aall and Koens [
68] discussed the discourse on sustainable urban tourism and the need for broader discussions beyond overtourism. The study highlighted the complexities of sustainable urban tourism and the importance of addressing multiple dimensions of sustainability beyond the issue of overtourism. McCabe [
69] discussed social tourism and its relevance in promoting tourism for all. The study highlighted the importance of social tourism in ensuring access to travel and tourism experiences for marginalized and disadvantaged groups, contributing to social sustainability.
4. Results
Based on tables published by “Quadros do Pessoal” for 2010 and 2020, we selected the ones by economic activity to collect data for the “accommodations, restaurants, and similar activities” sector to proxy for corporate performance in the tourism sector.
The impact of sectoral and firm characteristics on decent work and social sustainability is multifaceted. The number of firms, birth rate of firms, firms’ survival rate, firm size, turnover, GVA, inflation, and investment can all influence the quality of work and the social well-being within a sector. While factors such as a competitive market, higher survival rates, and larger firms can contribute to better working conditions and social sustainability, it is essential to consider the quality of employment, distribution of benefits, and long-term sustainability. Additionally, factors like turnover, inflation, and targeted investments play a significant role in shaping outcomes for workers and society.
The number of firms in a sector can have both positive and negative effects on decent work and social sustainability. A higher number of firms can indicate a competitive market, which may lead to better working conditions, higher wages, and increased job opportunities. On the other hand, many small firms could result in a lack of economies of scale, limited resources for investment in worker welfare, and potential exploitation of labor.
The birth rate of firms refers to the rate at which new firms are established. A higher birth rate can indicate a dynamic and innovative sector, potentially leading to job creation and economic growth. However, the impact on decent work and social sustainability depends on the quality of these new firms. If the new firms provide decent work conditions, fair wages, and promote social responsibility, it can have a positive impact. Conversely, if the birth rate is driven by informal or exploitative practices, it can harm decent work and social sustainability.
The survival rate of firms reflects the ability of firms to sustain their operations over time. A higher survival rate indicates a stable and resilient sector, which can contribute to decent work and social sustainability. Stable firms are more likely to invest in their workforce, provide training opportunities, and offer long-term employment. Conversely, a low survival rate may lead to job insecurity, reduced investment in worker welfare, and negative social consequences.
The size of firms can influence decent work and social sustainability outcomes [
70]. Larger firms often have more resources to invest in employee benefits, training programs, and work-life balance initiatives. They may also have better bargaining power to negotiate fair wages and working conditions. However, there can be instances where large firms prioritize profit maximization over employee welfare, leading to issues such as exploitation, limited job mobility, and reduced social sustainability.
High turnover rates can negatively impact decent work and social sustainability. Frequent turnover can indicate job instability, limited employee rights, and a lack of job security. It can also result in a loss of valuable skills and knowledge within the workforce. Conversely, lower turnover rates suggest more stable employment, better job quality, and improved social sustainability.
Gross value added (GVA) represents the value generated by a sector or firm through its economic activities. A higher GVA implies a larger contribution to the economy, which can potentially lead to increased investments in decent work practices and social sustainability. However, the distribution of GVA within the sector or firm is crucial. If the benefits primarily accrue to shareholders or top executives while neglecting worker welfare, it can lead to inequality and undermine social sustainability.
Inflation can impact the cost of living and the purchasing power of workers. High inflation rates without corresponding increases in wages can erode decent work and social sustainability. Workers may struggle to meet their basic needs, leading to increased inequality and social unrest. Conversely, controlled inflation with wage adjustments can help maintain decent work conditions and social sustainability.
Investment in the sector and firms can have a significant positive impact on decent work and social sustainability. Increased investment allows for the improvement of infrastructure, technology, and worker training, leading to higher productivity, better working conditions, and higher wages. However, the type and focus of investment matter. Investments that prioritize short-term gains over long-term sustainability may not result in lasting improvements in decent work and social sustainability.
Table 2 shows that, overall, the tourism sector generally exhibited similar trends to the overall economy in terms of firm size, turnover, and inflation. However, the tourism sector had a higher survival rate on average compared to all sectors. Additionally, the tourism sector’s specific performance can be further analyzed and compared year by year to gain more insights into its growth and stability.
In 2010, there was a total of 1,168,265 firms, with 85,964 firms in the tourism sector. In 2021, the total number of firms increased to 1,359,035, while the tourism sector had 111,094 firms. The number of new firms in the overall economy varied each year, ranging from 138,362 in 2010 to 187,036 in 2021. In the tourism sector, the number of new firms ranged from 9393 in 2010 to 11,043 in 2021. The survival rate of firms in the overall economy remained relatively stable, ranging from 69.7% in 2010 to 75.7% in 2021. The tourism sector consistently exhibited a higher survival rate, ranging from 73.2% in 2010 to 80% in 2021. The average size of firms in the overall economy remained fairly constant, at around 3.2–3.3 units. The tourism sector also maintained a similar average size, ranging from 3.3 to 3.4 units. Total turnover in the overall economy fluctuated over the years, with the highest value of 337,761.1 in 2010 and the lowest value of 300,134.5 in 2020. The turnover in the tourism sector followed a similar trend, with the highest value of 115,665.7 in 2010 and the lowest value of 85,550.9 in 2020. GVA in the overall economy showed variation, reaching its peak at 120,240.6 in 2021 and its lowest point at 91,378.4 in 2015. The tourism sector’s GVA fluctuated as well, with the highest value of 6329.2 in 2018 and the lowest value of 3138 in 2012.
Inflation rates in the overall economy varied, with the highest rate of 4.5% in 2012 and the lowest rate of −0.8% in 2021. The tourism sector experienced similar fluctuations in inflation, ranging from the highest rate of 4.5% in 2012 to the lowest rate of −0.8% in 2021. Total investment in the overall economy increased over the years, with the highest value of 22,807.9 in 2019 and the lowest value of 10,001.9 in 2020. In the tourism sector, investment levels also showed an upward trend, with the highest value of 6907.8 in 2019 and the lowest value of 3138 in 2012.
Employment plays a crucial role in promoting decent work and social sustainability by providing individuals with economic opportunities, income stability, and access to social benefits [
12]. It contributes to poverty reduction, social inclusion, and overall well-being [
13]. However, the quality of employment, including factors such as job security, fair wages, and working conditions, significantly influences the extent to which employment contributes to decent work and social sustainability [
13].
Table 3 shows the number of employees across sectors. The number of employees in the tourism sector shows a fluctuating pattern over the years, with variations in employment levels. From 2010 to 2012, the number of employees in this sector experienced a decline from 180,038 to 166,346. This could be indicative of economic challenges or specific factors impacting the sector during that period. After the initial decrease, the number of employees gradually increased, reaching a peak of 251,350 in 2019. This suggests a recovery and potential growth in employment within the sector. However, in 2020, the number of employees dropped to 214,079, likely due to the impact of the COVID-19 pandemic on the hospitality and service industries.
The growth rates provide a quantitative measure of the relative performance of the tourism sector compared to the total number of employees across all sectors. They highlight the year-to-year changes and trends in employment levels for both sectors. From the analysis, we can observe the following: The growth rates for both the total number of employees and tourism sector workers fluctuate over the years; the tourism sector generally exhibits higher growth rates compared to the total, indicating a relatively stronger performance in terms of employment growth. However, in 2020, both the total number of employees and tourism sector workers experienced a decline, likely due to the impact of the COVID-19 pandemic.
Table 4 shows the employed population by gender. The number of women employed in the sector has been consistently higher than the number of men, indicating a higher representation of women in the industry. However, the overall population of employed individuals in the services sector shows a higher percentage of women (approximately 49%) compared to men; This suggests that although there is a higher representation of women in the services sector as a whole, there is still a gender pay gap within specific industries, such as accommodation.
The table highlights a persistent gender pay gap in the accommodation tourism sector in Portugal. Despite improvements over the years, women continue to earn less on average compared to their male counterparts. The higher representation of women in the sector, as indicated by the employed population data, suggests that efforts should be made to address and reduce the gender pay gap, specifically within the accommodation industry. Further analysis and targeted policies may be necessary to promote gender equalization in terms of remuneration and earnings in this sector.
Work duration refers to the length of time individuals spend in employment. Long working hours without adequate breaks can lead to work-related stress, fatigue, and health issues, negatively impacting both decent work and social sustainability [
21]. Balancing work and personal life, ensuring reasonable working hours, and promoting work-life integration are essential for maintaining decent work and social well-being [
21].
Analyzing the average hours worked (
Table 5) by qualification level, we can observe that the tourism sector consistently exhibits higher average working hours compared to the overall average for all sectors. This suggests that employees in the tourism sector generally have longer working hours compared to the average for all sectors. Indeed, the average working hours for all sectors range from 39.3 to 39.5 h per week throughout the years. The average working hours for the tourism sector remain consistently higher, at 39.9 h per week. Across all sectors and qualification levels, the average working hours range from 38.0 to 38.6 h per week. In the tourism sector, the average working hours for all qualification levels are consistently higher, ranging from 39.8 to 40.0 h per week. This indicates that employees in the tourism sector tend to work longer hours compared to other sectors, regardless of their qualification level.
Part-time jobs can provide flexibility and employment opportunities for certain individuals. However, they can also contribute to job insecurity, reduced access to social benefits, and lower wages [
21]. The impact on decent work and social sustainability depends on the quality of part-time jobs, including such factors as fair remuneration, benefits, and opportunities for career advancement [
21].
Table 6 highlights the number of workers with part-time jobs. The tourism sector shows remarkable growth in the number of part-time employees, outpacing the growth rate of all sectors. This indicates the sector’s increasing reliance on part-time employment and its relative significance in the labor market. The total number of part-time employees shows fluctuations over the years, but there is an increasing trend. For all sectors, the number of part-time employees increased from 169,282 in 2010 to 212,932 in 2021, representing an overall growth rate of approximately 25.77% over the period.
In the tourism sector, the number of part-time employees increased from 13,836 in 2010 to 27,675 in 2021, which indicates a significant growth rate of approximately 100.12% over the period. The tourism sector has a consistently higher number of part-time compared to all sectors (total), indicating its relative dominance in part-time employment within the analyzed sectors. The growth rate of the tourism sector is generally higher than the growth rate of all sectors (total), which emphasizes its stronger performance in terms of part-time employment.
Wage levels directly affect workers’ livelihoods and economic security. Inadequate wages can lead to poverty, inequality, and social exclusion and thereby undermine social sustainability [
19]. Promoting fair and living wages is essential for ensuring decent work and reducing income disparities [
19]. The average wages in the tourism sector can vary depending on factors such as job type, qualifications, and experience. In general, wages in the tourism sector tend to be lower compared to some other sectors. This can be attributed to factors such as the prevalence of low-skilled and entry-level positions, seasonal fluctuations, and a highly competitive market. However, it is essential to ensure that wages are fair and provide a decent standard of living for workers in order to promote social sustainability.
Table 7 displays the average monthly base remunerations and growth rates. These growth rates highlight the year-to-year changes and trends in remuneration levels for both sectors, with the tourism sector generally showing stronger growth in remuneration. From the analysis, we can observe that both the total average monthly remuneration and the average monthly remuneration for the tourism sector show fluctuating growth rates over the years. The tourism sector generally exhibits higher growth rates compared to the total, indicating a relatively stronger performance in terms of remuneration growth. The growth rates for both sectors show positive trends, indicating an overall increase in remuneration levels.
Table 8 shows the average base salary by gender.
The average base salary for both men and women in the accommodation, restaurant, and similar sectors has increased over the years: In 2010, the average base salary for men was higher than for women (742.8 euros vs. 602.5 euros). This trend continued in subsequent years, but the gap narrowed. In 2021, the average base salary for men in the sector was 883.1 euros, while for women, it was 775.5 euros; Although there has been progress, a gender pay gap persists, with women consistently earning less than men in the accommodation sector.
Table 9 allows us to analyze the average monthly earnings. Similar to the base salary, the average monthly earnings for both men and women in the sector have increased over time: In 2010, the average earnings for men were higher than for women (818.7 euros vs. 654.5 euros). This gap gradually decreased but remained significant. In 2021, men earned 987.7 euros on average, while women earned 856.5 euros in the sector; The gender pay gap in terms of average monthly earnings persists, indicating a disparity in overall compensation.
Table 10 displays the growth rates of average earnings by region. It highlights the variations in average earnings and growth rates across economic sectors and regions, emphasizing the relatively stronger performance of the tourism sector compared to all sectors (total). Specifically, both all sectors (total) and the tourism sector experienced growth in average earnings over the years, except for some negative growth in certain years. The growth rates for all sectors and the tourism sector vary by region and year.
For all sectors, the regions of Lisboa and Algarve consistently show higher growth rates of average earnings compared to other regions. In contrast, the tourism sector shows more fluctuation in growth rates across regions and years. In most years, the tourism sector outperforms all sectors in terms of growth rates, indicating that it had a relatively stronger performance compared to other sectors. The year 2018 stands out as a significant year for the tourism sector, with a relatively higher growth rate compared to all sectors, particularly in the region of Lisbon.
Table 11 shows the evolution of real average wages. We can observe that in some years, the tourism sector had lower real average wages compared to the total sectors (e.g., 2010, 2011, 2012, and 2015). However, there were also years where the tourism sector had higher real average wages compared to the total sectors (e.g., 2014, 2018, 2019, and 2021). Overall, the tourism sector shows some fluctuations in real average wages over the years compared to the total sectors.
Unionized workers and collective work agreements play a vital role in protecting workers’ rights, ensuring fair wages, safe working conditions, and promoting social dialogue [
6]. They contribute to decent work by advocating worker’s well-being and influencing labor policies and practices [
6]. Unionization can enhance social sustainability by fostering social cohesion, empowerment, and collective action [
6].
Table 12 shows the number of unionized workers or whose contract is under a collective bargaining agreement. It provides insights into the extent of coverage under different labor protection schemes. These schemes, such as collective bargaining agreements (CCT), employee representation (AE, ACT), and labor inspections (RCM, TCO), aim to safeguard workers’ rights, promote fair working conditions, and ensure social sustainability. By analyzing the number of workers covered by these schemes, it becomes possible to assess the level of protection provided to employees within the tourism sector. The presence of labor protection schemes indicates a commitment to upholding workers’ rights, including fair wages, reasonable working hours, occupational health and safety measures, and access to social benefits. When a significant number of workers in the tourism sector are covered by these schemes, it suggests a higher likelihood of decent work conditions, fair treatment, and social sustainability.
Labor protection schemes often contribute to the establishment of social safety nets for workers. These safety nets include provisions for healthcare, pension schemes, unemployment benefits, and other forms of social security. By providing such benefits, workers have a safety net that supports their well-being, protects against unexpected financial burdens, and promotes social sustainability.
Analyzing the coverage of labor protection schemes can also reveal any potential disparities or inequalities within the sector. Certain groups of workers’ underrepresentation or exclusion from these schemes may indicate a need for targeted measures to address social inequalities and ensure equal opportunities for all workers.
The total number of workers covered by AE, ACT, CCT, PRT/PCT, and TCO shows a fluctuating trend over the years. From 2010 to 2021, the total number of workers under those circumstances increased from 2,392,229 to 2,454,688, indicating a slight increase of approximately 2.6%. The number of unionized workers in the tourism sector also experienced fluctuations throughout the years. From 2010 to 2021, the number of unionized workers in the tourism sector increased from 176,519 to 207,875, reflecting a growth rate of approximately 17.8%. The growth rate of unionized workers in the tourism sector (17.8%) is significantly higher compared to the overall growth rate of all sectors (2.6%). This indicates that the tourism industry has experienced relatively stronger growth in terms of unionized employment compared to other sectors. This growth can be attributed to the improvement of labor conditions due to law enforcement.
Work accidents and sick leaves due to accidents have detrimental effects on both workers and organizations. They can lead to physical and psychological harm, loss of income, and increased healthcare costs [
23]. Ensuring occupational health and safety measures, promoting a safe working environment, and providing adequate support for injured workers are crucial for achieving decent work and social sustainability [
23].
Table 13 and
Table 14 show the number of work accidents and days of sick leave due to the accident. The tables highlight the importance of ensuring a safe working environment within the tourism sector. By tracking accidents at work and the resulting lost workdays, organizations and policymakers can identify areas that require improvement in terms of occupational health and safety practices. Prioritizing workplace safety helps protect workers’ physical and psychological well-being, reduces accidents, and promotes social sustainability. Workplace accidents can have detrimental effects on workers, including physical injuries, psychological distress, loss of income, and increased healthcare costs. By monitoring and addressing the causes of accidents, organizations can better protect employee well-being, enhance job quality, and contribute to social sustainability.
In 2020, there were a total of 2796 workplace accidents across all sectors. Within the tourism sector, there were 12 workplace accidents. When comparing the total number of accidents, the tourism sector represents a small portion of the overall incidents.
Lost workdays due to accidents can result in productivity losses for both workers and organizations. By quantifying the number of days lost, policymakers and employers can assess the economic impact of workplace accidents. Implementing measures to prevent accidents and provide adequate support for injured workers can reduce productivity losses, contribute to sustainable economic growth, and support social sustainability.
Over the years, the total number of lost workdays due to workplace accidents has varied. In 2020, there were 4,389,303 lost workdays in total. The tourism sector accounted for 222,850 lost workdays in 2020. Although the tourism sector experiences a significant number of lost workdays, it represents a smaller proportion compared to the total lost workdays across all sectors. In general, the tourism sector shows a relatively lower number of workplace accidents and lost workdays compared to the total figures across all sectors.
We can now summarize the key findings for each social sustainability indicator shown in

Table 14:
Number of firms: The tourism sector in Portugal has seen an increase in the number of firms over the years, indicating potential job opportunities and competition. This can contribute to better working conditions and social sustainability.
Birth rate of firms: The tourism sector has shown a moderate increase in the birth rate of firms, indicating a dynamic and potentially innovative industry. However, the impact on social sustainability depends on the quality of these new firms.
Survival rate of firms: The tourism sector has consistently exhibited a higher survival rate compared to all sectors, indicating a stable and resilient industry. This can positively impact decent work and social sustainability.
Firm size: The average size of firms in the tourism sector has remained relatively constant and comparable to the overall economy. Larger firms generally have more resources to invest in employee benefits and working conditions, but it is crucial to ensure they prioritize employee welfare for social sustainability.
Turnover: Turnover in the tourism sector has followed a similar trend as the overall economy, suggesting its alignment with broader economic conditions. Stable employment and lower turnover rates contribute to better job quality and social sustainability.
Gross value added (GVA): The GVA in the tourism sector has fluctuated over the years, but it has generally contributed to the economy. It is important to ensure that the distribution of GVA benefits workers and promotes social sustainability.
Inflation: The tourism sector has experienced fluctuations in inflation rates similar to the overall economy. Controlling inflation and ensuring corresponding wage adjustments are important for maintaining decent work conditions and social sustainability.
Investment: Investment in the tourism sector has shown an upward trend, indicating potential improvements in infrastructure, technology, and worker training. However, it is important to ensure that investments prioritize long-term sustainability and decent work practices.
Employment: The number of employees in the tourism sector has fluctuated over the years, with indications of recovery and potential growth. The COVID-19 pandemic has had a significant impact, leading to a temporary decline in employment levels.
Gender representation: The tourism sector has a higher representation of women compared to men, indicating opportunities for gender equality. However, a persistent gender pay gap exists, requiring targeted policies to address and reduce the disparity.
Work duration: Employees in the tourism sector generally work longer hours compared to the average for all sectors. Balancing work and personal life is crucial for maintaining decent work and social well-being.
Part-time jobs: The tourism sector has shown remarkable growth in the number of employees in part-time jobs, outpacing the growth rate of all sectors. This trend raises concerns about job insecurity, reduced access to social benefits, and lower wages for part-time workers. The quality of part-time jobs and their impact on social sustainability need to be considered.
Wage levels: The average monthly base remunerations and earnings have increased over time in the tourism sector. The sector generally exhibits stronger growth in remuneration compared to the overall average for all sectors.
Gender pay gap: Despite improvements, a gender pay gap persists in the tourism sector, with women consistently earning less than men. Further efforts are needed to address and reduce this disparity.
Average monthly earnings: Both men and women in the tourism sector have experienced an increase in average monthly earnings over time. However, a gender pay gap remains, indicating a disparity in overall compensation.
Growth rates of average earnings by region: The growth rates of average earnings vary across regions and years in both the tourism sector and all sectors. Regional disparities need to be considered for inclusive social sustainability.
In a nutshell, the tourism sector in Portugal exhibited both positive developments and challenges in terms of social sustainability between 2010 and 2020. While the sector has shown growth, stability, and improvements in remuneration, there are nevertheless persistent issues, such as the gender pay gap and the increasing reliance on part-time employment. Addressing these challenges, promoting gender equality, ensuring decent working conditions, and supporting sustainable growth are essential for enhancing social sustainability in tourism firms in Portugal.
5. Discussion
The concept of decent work, as defined by the International Labour Organization (ILO) [
13], encompasses four pillars: employment creation, social protection, rights at work, and social dialogue. It emphasizes the provision of productive work opportunities with fair income, secure workplaces, personal development prospects, freedom of expression and organization, and equality of opportunity and treatment for both men and women. However, empirical research reveals a mixed perception of the quality of work, working conditions, and practices in the tourism sector from a “decent work” perspective [
12,
14,
15].
The literature highlights several issues within the tourism workplace that affect the achievement of decent work. These include informal work arrangements, extended working hours, low wages, limited social protection, and gender discrimination [

18,
19,
20,
21,
22,
23,
24,
25,
26,
27,
28]. Moreover, inadequate working schedules, insecure employment contracts, overwork, insufficient pay, lack of progression opportunities, missed mealtimes, wage disputes, low recognition of trade unions, income insecurity, split shifts, unpaid overtime, physical violence, sexual harassment, and stress are prevalent concerns [
25,
29,
30,
31]. Additional issues identified in the literature include lack of respect and recognition, limited workplace autonomy, monotonous tasks, poor communication, inadequate fixtures and fittings, issues related to people’s identity at work, sexualized labor, sex tourism, racism, and seasonality [
32,
33,
34,
35,
36].
It is important to recognize that decent work extends beyond job creation and emphasizes the quality of employment [
13]. Workplace dignity is positively correlated with corporate social sustainability, suggesting that firms need to provide decent working conditions to enhance social sustainability [
37]. The study categorizes corporate social sustainability indicators into eight dimensions: physical working conditions, wages, career development, health, community, clients, competitors, and the economy [
37]. These indicators, derived from the literature, reflect the stakeholders’ perspective and cover a range of aspects relevant to social sustainability.
Social sustainability in tourism often focuses on specific aspects such as community engagement, local perceptions, and social impacts. It emphasizes the involvement of local communities in tourism development and the promotion of their well-being. This approach typically addresses issues such as community participation, cultural preservation, and the equitable distribution of benefits. While important, this narrow definition may overlook other crucial dimensions of social sustainability, such as labor rights, gender equality, social justice, and inclusive practices.
Adopting a broader approach to social sustainability in tourism involves expanding the scope beyond community involvement to encompass a wider range of social considerations. This includes addressing issues related to decent work, fair employment practices, social justice, gender equality, human rights, and the well-being of all stakeholders involved in the tourism sector. By adopting a comprehensive perspective, tourism destinations and stakeholders can strive to create an inclusive, equitable, and socially responsible tourism industry.
In the context of tourism and Portugal, social sustainability encompasses not only the involvement and well-being of local communities but also considerations such as labor conditions, gender equality, cultural diversity, and social inclusion. Portugal has recognized the importance of social sustainability in its tourism development strategies and policies. The country has made efforts to promote responsible tourism practices, support local communities, and safeguard cultural heritage. However, challenges still exist, including issues related to seasonality, informal work, labor rights, and the need for more inclusive and equitable tourism practices.
International and EU Operational Environment for Socially Sustainable Tourism: At the international level, organizations like the United Nations World Tourism Organization (UNWTO) and the International Labour Organization (ILO) play significant roles in promoting socially sustainable tourism. The UNWTO has developed guidelines and initiatives to support destinations in achieving social sustainability objectives. The European Union (EU) also emphasizes social sustainability in its tourism policies, highlighting the need for responsible and inclusive tourism development.
The results indicate an increase in the number of firms in the tourism sector, suggesting potential job opportunities and competition. The growth in the number of firms can contribute to better working conditions and social sustainability. Further, the results show a moderate increase in the birth rate of firms in the tourism sector. This indicates a dynamic and potentially innovative industry. Encouraging the birth of new firms can contribute to the overall social sustainability of the tourism sector. Both findings align with the results of [
54], which emphasizes the importance of local community perceptions and development guidelines for socially sustainable tourism in cities. Moreover, the results show that the average size of firms in the tourism sector has remained relatively constant and comparable to those in the overall economy. Larger firms generally have more resources to invest in employee benefits and working conditions, in agreement with [
70].
Replying to the research question: “What are the employment and remuneration trends in the tourism sector in Portugal, and what are the implications for social sustainability?” The results indicate that employment and remuneration trends in the tourism sector in Portugal have shown both positive developments and challenges in relation to social sustainability.
Tourism firms in Portugal between 2010 and 2020 have made contributions to the social dimension of the Sustainable Development Goals (SDGs) in various ways.
Job Opportunities and Competition: The increase in the number of firms in the tourism sector suggests potential job opportunities and competition. This contributes to SDG 8 (Decent Work and Economic Growth) by creating employment opportunities and promoting economic development. However, it is essential to ensure that these job opportunities come with fair wages, adequate working conditions, and opportunities for career advancement to fully address the social dimension of SDGs.
Stability and Resilience: The tourism sector has exhibited a higher survival rate compared to other sectors, indicating its stability and resilience. This is beneficial for SDG 1 (No Poverty) as it helps provide stability and economic opportunities for individuals and communities. Stable employment contributes to poverty reduction and social well-being.
Gender Representation and Pay Gap: The higher representation of women in the tourism sector suggests opportunities for gender equality, aligning with SDG 5 (Gender Equality). However, the persistent gender pay gap indicates a disparity in overall compensation. To fully contribute to SDG 5, efforts should be made to address and reduce the gender pay gap and ensure equal opportunities for women in terms of wages, job positions, and career advancement.
Part-time Employment and Job Insecurity: The growth in the number of employees in part-time jobs raises concerns about job insecurity, reduced access to social benefits, and lower wages. This poses a challenge to SDG 8, as it may lead to inequalities and hinder the social well-being of individuals. To contribute positively to the social dimension of SDGs, tourism firms should strive to provide stable and secure employment with fair working conditions for all employees.
Wage Levels and Job Quality: The increase in average monthly base remunerations and earnings in the tourism sector indicates some improvement in job quality. This aligns with SDG 8, as decent wages contribute to reducing inequalities and improving living standards. However, efforts should continue to address the persisting gender pay gap and ensure that wage increases are inclusive and benefit all employees.
Overall, tourism firms in Portugal from 2010 to 2020 have made contributions to the social dimension of SDGs through job creation, stability, gender representation, and improved wage levels. However, challenges remain, such as the gender pay gap and the reliance on part-time employment. To enhance their contribution to the social dimension of SDGs, tourism firms should prioritize fair working conditions, equal opportunities, and sustainable employment practices that benefit all employees. Additionally, collaboration between government, industry stakeholders, and communities is crucial to address these challenges and achieve sustainable social development in the tourism sector.
Furthermore, maintaining good relationships with stakeholders can enhance a firm’s social sustainability by developing and preserving intangible assets [
44]. Workplace benefits, such as improved health and safety conditions, can motivate employees, foster loyalty, reduce recruitment and training costs, and increase productivity [
45,
46]. Socially sustainable practices can also contribute to a firm’s sustainable competitive advantage by enhancing reputation and consumer trust in brand value [
47,
48].
Exploitative employment practices often lead to employee dissatisfaction and disengagement, high absenteeism, and resignation. Such feelings negatively affect client satisfaction and indirectly impact economic viability [
71,
72]. The lack of decent work in tourism poses a threat to future recruitment, engagement, and retention [
73,
74,
75].
A renewed understanding of decent work, promoting dignity and fostering positive changes in firms’ settings, can be key to achieving decent tourism employment, as envisaged in SDG8 [
76]. Actions such as integrating dignity in the workplace through communication and manager education [
77], taking pride in work as a meaningful contribution to the organization’s success, reaffirming one’s values and capabilities to overcome low social standing [
78], and promoting a more humanistic and collaborative approach to running operations [
79] are suggested in the tourism literature.
This research provides quantitative data and trends on employment and remuneration in the accommodation sector, enabling policymakers and stakeholders to make informed decisions. The analysis of the gender pay gap and gender representation adds an important dimension to the study, highlighting the need for gender equality measures in the sector. The examination of regional variations offers insights into regional disparities and the potential for targeted policies to address specific challenges in different regions.
While our study sheds light on prevailing trends in tourism work conditions and contributes to understanding decent work within the context of tourism employment and the broader global sustainability agenda, it is important to critically assess the limitations of our research. Firstly, the lack of comparable data on global work quality [
80] hinders a comprehensive analysis of the quality of work in the tourism sector. This limitation restricts our ability to make robust comparisons and draw definitive conclusions about the social sustainability of tourism employment beyond the Portuguese context. Secondly, the concept of decent work itself lacks a clear and universally accepted definition [
81]. This ambiguity introduces challenges in assessing and measuring decent work, making it difficult to fully capture its implications for social sustainability in the tourism sector. Additionally, conflicts arise between the goals of economic growth, full employment, and decent work [
82,
83,
84]. These tensions highlight the complex trade-offs that policymakers and businesses face in pursuing social sustainability while ensuring economic prosperity and job creation. Moreover, neoliberal practices in the workplace, emphasizing competition, progress, and profitability [
85] can have adverse effects on job quality, security, and benefits. These practices may undermine the social sustainability of tourism employment by prioritizing financial gain over the well-being of workers. Furthermore, the difficulty in aligning social sustainability objectives with measurable indicators [
72,
84,
85] poses challenges in assessing progress and setting normative targets. The lack of conceptual clarity in the field of social sustainability further complicates the task of effectively measuring and monitoring social sustainability outcomes in the tourism sector.
This study’s reliance on outdated data [
80,
86] limits our ability to capture recent developments and trends in the tourism sector. This restricts the depth of our understanding of the underlying causes and dynamics influencing employment and remuneration in the industry. Additionally, our analysis does not provide a comprehensive examination of all relevant factors that may influence employment and remuneration trends, such as economic conditions, policy changes, or industry-specific dynamics. This narrow focus limits the holistic understanding of the complex interplay between social sustainability and employment dynamics in the tourism sector. Furthermore, while statistical data can provide valuable insights, they have inherent limitations in capturing qualitative aspects, personal experiences, and diverse perspectives. Social sustainability is a multifaceted concept that cannot be fully captured by numbers alone [
80,
81]. Therefore, complementing statistical sources with qualitative research methods, stakeholder consultations, and participatory approaches would enhance our understanding of social sustainability in tourism by incorporating the perspectives and experiences of relevant stakeholders.
By and large, this analysis underscores the significance of corporate social sustainability in the tourism sector. It emphasizes the need for businesses to prioritize decent work, provide safe and fair working conditions, and promote equitable pay practices. By doing so, firms can enhance their social sustainability, maintain positive relationships with stakeholders, and contribute to their sustainable competitive advantage. Policymakers should work towards creating an enabling environment that supports these principles and fosters the long-term sustainability of the tourism industry. However, while this study provides valuable insights and highlights important trends, further research and analysis considering a broader range of factors would enhance the understanding of the dynamics within the tourism sector and facilitate the development of more targeted policies.
