One of the core managerial responsibilities is to fill vacant or newly created jobs with suitable employees. Similar to [
1,
2,
3], we support the systemic human resources management. A strategic approach to the effective sustainability of the recruitment process requires the planning of human resources needs, job analysis reflected in job descriptions, and job specifications [
4]. An important part of the enterprise’s strategy is employer branding—strong branding and employer value proposition for potential and current employees [
5,
6]. Enterprises that have developed their brand by providing a popular product are better placed to get quality workforce and talented people [
7]. Chhabra and Sharma [
8] identified common organizational attributes which were compensation, career prospects and growth, job profile, brand name, corporate culture, employee empowerment, training and development, supportive and encouraging colleagues, innovative employer/novel work practices, humanitarian organization gives back to society, job security, recognition/appreciation, having a good relationship with supervisor, the organization is customer oriented, and acceptance and belonging. Several different concepts created by Berthon et al. [
9], which emphasize employers’ attractiveness as the envisioned benefits that a potential employee sees in working for a specific organization, are image and branch equity. While the result of employer branding is to attract and retain high-quality and talented employees, the role of Human Resource Recruitment and Marketing is to occupy a specific job with a suitable job seeker.
Recruitment strategy and policy are significantly affected by both the internal and external environment [
10]. The recruitment process consists of three consecutive phases, starting with searching, continuing by addressing the right people, and ending with the selection of potential employees. The advantage of internal searching is the acquaintance of employees, support for flexibility and internal mobility reflected in career development, stabilization, and improvement of work ethics [
11]. From an economic point of view, the cost of getting an employee to another job is lower; employees are familiar with the corporate culture and business goals. The disadvantage is a certain routine in the implementation of the established activities and lower openness to new approaches from the external labor market. The reason for looking for employees from external sources is the need to fill a job, but also the need to change the professional or age structure of employees with new competencies, thoughts, and ideas.
The aim of the second phase is to find the best job seekers and to form a workforce that matches the present and future needs of the enterprise. Identifying the most appropriate person to perform a job is a big dilemma, the core of which is to find a way to reduce errors in the prediction of a suitable candidate. Over the last decades, psychologists focus on reducing predictive errors by developing standardized recruitment procedures using a combination of multiple methods [
12]. The new ways include e-recruitment, which utilizes available computer network services, especially web sites and e-mail [
13]. In addition to the above-mentioned electronic recruitment procedures, the Internet offers employers additional options for communicating with potential job seekers, such as creating and developing social networks (Facebook, LinkedIn, Myspace, and Google+), and virtual communities of users with common interests. Social networks enable job seekers to publish their professional and personal profiles and give employers the opportunity to reach out to suitable job candidates in their enterprise.
The third phase of recruitment process is linked to selection and hiring. The effectiveness has to be considered while choosing the selection techniques, which is assessed using three criteria: Reliability, validity, and usefulness [
14]. Reliability means that the selected person (if the working conditions are not completely changed) performs the same work repeatedly or his/her behavior is completely or approximately the same even after a few months. Validity is the rate of prediction of successful work based on selection [
15]. Usefulness refers to the suitability of the selection technique used in relation to the nature of the work and the type of an occupied job. In assessing the employee recruitment process, Wilton [
16] recommends examining the costs of administrative work, job offerings, organizing the selection process, and the costs of employee fluctuation due to the selection of the wrong person. Dvořáková [
17] highlight the need to reallocate costs to one applicant, demonstrating the usefulness, validity, and reliability of the selection.
The variety of different types of social networks also allows a wide range of use. In this paper, we refer to key aspects of the recruitment process that can affect managers’ access to effective staffing in the enterprise. The aim of the paper is to present the current state and the possibilities of using social networks in the process of recruiting employees in SMEs, which is based on a long-term sustainable strategy eliminating traditional attitudes and the demanding administrative procedures used in this field. We verify the assumption that social networks are becoming an important tool for labor market orientation and an instrument of public opinion for enterprises. Using a sociological questionnaire, we examine the reasons for using social networks in SMEs, with emphasis on the recruitment process.
1.1. Social Networking
The original term “social network” has not been linked to Internet social networks. It has expressed a group of people who associate due to a particular social interaction [
19]. Using a set of technologies, so called social media, the interconnection between individuals and groups in the virtual space through a joint communication platform has been established [
20,
21]. Social media, according to Li and Bernoff [
22], allow people to exchange ideas and opinions, to jointly download site content, and to build contacts online. There are differences in comparison to classical media, as each user creates their content and can also contribute or comment on it. Social media have a variety of forms, such as text, audio, video, photo, and other image forms, that connect communities and reach out to people who want to join. Social media include social networks, such as Facebook, Twitter, and others, as well as WordPress management systems, products created by joint efforts, such as Wikipedia, blogs, chat rooms, photo sharing sites, videos, and more. Social media is an infrastructure that creates contacts and transfers information [
23]. Kaplan and Haenlein [
24] differentiate between six types of social media: Collaborative projects, blogs and microblogs, content communities, social networking sites, virtual game worlds, and virtual social worlds.
Each type of social media has its own users with mutual relationships among them. Social networks are groups of people, communities that have shared similar interest or views. By Zimmerman and Ng [
25], social networks are generally user-friendly. In common practice, social networks consist of profiles that are created and completed by users themselves. Users can view information from friends, acquaintances, and enterprises, read and comment on posts, and upload content, either their own or downloaded from other sources [
26]. Social networks are also used by enterprises to present themselves on the Internet. They are based on establishing relationships between self-acting users who create networks and spread information to each other. These relationships increase the credibility of the information, as users know their source and believe the content is true. We can conclude from the above that two types of relationships arise on social networks: Mutual relations between users and user
–brand relations. It is important for enterprises to build a user
–brand relationship. Social networks are thus becoming an important tool for influencing the public, both on product offers and on tracking and influencing attitudes towards the brand itself. The enterprise’s brand can affect the decisions of jobseekers positively or negatively.
An important part of social media is the social environment that forms a range of acquaintances, cities, and interests that characterize how and why people connect through social networks. The concept of the social environment was popularized by Facebook founder Mark Zuckerberg in 2007 to explain the reasons for his company’s growth.
Every social networking or content sharing site offers communities assisting users “help” in personal and/or business use. A useful framework is the Honeycomb of Social Media adapted by [
27]. The honeycomb framework consists of the following seven blocks: Conversations, identity, sharing, presence, relationships, reputation, and groups. The differences in individual blocks are reflected in several types of social networks that differ from one another in their focus, level of privacy, or popularity. In particular, they are information, education, professional, or community networks. Each of the social networks offers different options and functionality [
28].
White [
29] divides social networks according to their content: Social, multimedia, professional, informational, educational, and interest networks. The primary purpose of professional networks is to offer opportunities for career development, and to get suitable jobseekers. Employers have the opportunity to look at profiles of potential employees, their previous experience and qualifications, and offer them a job if they are interested. When creating business profiles on social networks, according to Scott [
30], the following recommendations need to be respected:
Reach a particular audience in a way that interests them, i.e., to use the language of the target group;
Be a think-and-guide and offer interesting and valuable information that people are looking for, show what the enterprise is good at, how to solve employee and customer problems, and not only promote the products;
Be transparent and authentic, not to impersonate someone else and avoid unfair practices;
Encourage people to get in touch with the enterprise, do everything to make it easy to find a corporate website, to reserve enough time to answer questions;
Participate, create groups and regularly join Internet debates;
Experiment, try new things, bring a variety of ways to establish contact and create interest.
Social networks, considering their growing trend, help enterprises to become visible to consumers as well as potential employees. Interest in social networks and content sharing are increasing between individual users and enterprises alike. This trend is confirmed by the study of Mikalef and Pateli [
31], which builds on the technology
–organization
–environment (TOE) framework. Their results (conclusions) show the openness of large corporations and enterprises with a broad external knowledge transfer scope to adopt social media as part of their open innovation strategy. Social media adoption for open innovation is determined by a factor related to the company’s organizational and environmental context. The users of information posted on social networks are individuals or groups of different age categories. Pateli and Mikalef [
32], in their study, also state that social media have managed to radically change the way in which people interact, and thus have outpaced the adoption of several previous communication innovations, such as mobile phones, Internet, and television. Facing the dramatic increase of social media use, businesses are beginning to explore how these tools can help them grow and improve profits, not just with common practices such as marketing, but as part of their business collaboration and open innovation practices.
In Slovakia, social networking is no longer an issue of only the younger generation. This results from a survey by Gfk [
33], conducted in 2016 on a sample of 1199 respondents over the age of 15 (
Figure 1).
Among young people, 89% of generation Z (born after 1995) use social networks every day, 67% of generation Y (born 1966–1979), and 53% of the generation X (born before 1979) use social networks every day. There are differences in user involvement in social networks. While generation Z uses, on average, 5.2 different networks, generation X uses an average of 2.8 different networks.
1.2. Types of Social Networks
When creating content on social networks, it is necessary to respect the principles of user’s behavior, be creative, stay on top of things, and be self-critical, in other words, the attributes that attract attention [
34]. This statement led us to the need to explore the focus on social networks and their users from the point of view of corporate sustainability. The corporate sustainability concept should respect the economic, environmental, and social line [
35]. An enterprises’ main communication tool with the public is its website and presence on social networks. Enterprises should not only depend on their own benefit by acquiring reliable and efficient employees, but should also monitor the interests of customers, job seekers and employees, develop ethically correct relationships with them, present true website data, and create proper working conditions and social security in the workplace to develop resources for future generations.
The MySpace Social Network has been on the market since 2003, allowing its users to create a one-page yet comprehensive presentation. The presentation may contain graphic, text, or multimedia elements. Users can communicate with each other, but the “who to whom belongs” principle is applied. In some countries, MySpace is a popular service. In our territory, it is mainly used for the presentation of cultural events, musical groups, theater ensembles, etc. [
36,
37].
LinkedIn primarily connects a professional community. Upon its launch in 2003, the data from business networks of more than 40 million users were collected and LinkedIn became the largest and the most important business social network. It connects people from diverse spheres, from consultants, through to HR managers, to people in the IT sector [
38]. The aim is mainly to establish business relationships, to find employment, or to recruit employees. The advantage of the network is that each member can set up and manage groups that associate similarly professional or opinion-oriented people. This network is particularly interesting for individuals, associations, or communities looking for the right contacts [
23].
Twitter, despite media support by engaging celebrities compared to MySpace and Facebook, has more limited opportunities [
39]. Users, so-called tweets, can send and read text messages with a maximum of 140 characters, which are displayed on the user’s page. They are usually publicly visible, but the privacy of these messages can be changed using special settings. Twitter offers the user to set his/her own background or design his/her profile [
40]. Users can share photos and web links with others with abridged URLs. The popularity of Twitter, despite the simplicity of the infrastructure, is increasing and other social networks are learning its functionality.
Facebook, the world’s most used social network, dates back to 2004. Originally, membership was only allowed to Harvard University students. Facebook was released to the public in September 2006 [
41,
42]. Facebook differs from many other networks by the level of customization, many types of communication, and interaction. Since 2008, Facebook is the leading social networking site, based on monthly unique visitors, having overtaken the main competitor, MySpace. One of the popular interactions is to join groups of colleagues, classmates, or people with the same interests.
Google+ [
43] is a social network operated by Google since June 2011, with integration through Google products, including Buzz. One of the key elements of Google+ is to focus on targeting the user’s profiles by creating social groups called “circles” [
44]. Circles are small groups of people that can be named by the relations, such as a circle of friends, a family circle, classmates, and co-workers. Even within Google+, Google has created a special chapter for viewing, managing, and editing multimedia. Any content can be shared, from internet links to photos, and this social network also offers its own photo editor. The editor allows users to edit the photo directly on the social network.
Skype [
45] is a free program, available anywhere in the world. By simple installation and registration, the user has all the features available. Skype is very popular, especially among young people, but it is also used by enterprises to communicate with their distant employees or simply to make conference calls with business partners. For a small fee, the user gets additional features. For example, calling to mobile phones, accessing WiFi, or sending SMS. It is possible to pay for services either continuously or in advance. Skype accounts can be linked to accounts of other social networks. Skype now supports activities in 38 world languages.
YouTube [
46] is an online database, mostly of short videos. It was created in 2005 and was acquired by Google in 2006. It is currently the largest network to share video files on the Internet. Users create profiles for uploading videos on YouTube, creating their own channels, or marking individual videos as favorites. Profiles are linked to Google login. YouTube is used by enterprises to promote their activities through video.
1.3. Corporate Sustainability in SMEs
SMEs play a very important economic and social role, both through their importance in the economy and in job creation, a role which is greatly appreciated in these times of ever-increasing globalization. The European Commission defines SMEs as businesses which employ less than 250 staff and have an annual turnover of less than 50 million EUR, and/or their balance sheet total is less than 43 million EUR. Staff headcount is the main factor determining whether an enterprise is a SME. Further factors determining whether an enterprise is a SME are turnover and balance sheet total. The data to apply to the headcount of staff and the financial amounts are those relating to the latest approved accounting period, and are calculated on an annual basis. They are taken into account from the date of closure of the accounts. The amount selected for the turnover is calculated, excluding value added tax and other indirect taxes. However, it would not be desirable to use turnover as the sole financial criterion, in particular because enterprises in the trade and distribution sector have, by their nature, higher turnover figures than those in the manufacturing sector.
According to data from the Slovak Business Agency for the year 2016, SMEs in the Slovak Republic represent as much as 99.9% of the total number of entrepreneurial subjects, provide job opportunities for nearly 75% of the active workforce, and contribute to gross production and creation of added value by more than 50%. Additionally, they are a source for new innovations and technologies, create a competitive environment, enhance economic growth, and at the same time produce and offer products or services that large corporations are not willing to provide [
47].
Employees are one of the sources of the strategic competitive advantage; therefore, the opportunities for their career growth can be beneficial for the staff quality in key positions, mainly in SMEs. Getting and stabilizing capable and efficient employees in an enterprise is the duty of managers. Each of the HRM processes needs to be carried out in line with Sustainability Characteristics. The Brundtland Commission [
48] defined sustainable development as development which meets the needs of the present without compromising the ability of future generations to meet their own needs. Since then, the term corporate sustainability has emerged and been defined many times.
Sustainability should go beyond social and environmental responsibility, and should include all management processes that aim at creating long-term well-being [
49]. According to Marrewijk [
50], corporate sustainability focuses on value creation, environmental management, environmental friendly production systems, human capital management, and so forth. Corporate sustainability requires managers to measure and supervise this internal development, as well as to engage in a dialogue with external stakeholders on sustainable development issues [
51]. Sustainability does not mean that an enterprise adopts a one-size-fits-all approach [
52]. Thus, SMEs owner–managers are challenged to choose and implement a set of tools that help them operationalize corporate sustainability relevant to their particular business and surroundings [
53].
The recruitment process and its sustainability are influenced by external factors, but primarily by decisions of managers covering all HRM processes, corporate culture, and workplace climate. Managers adopt guidelines about which sustainability management tools may be adequate for the enterprise. If there is no interest in a job in a particular enterprise or in a job offer, there is a need to analyze the internal conditions and compare the average wage, employee benefits, work regime, and other work conditions with competitors. It is not enough to have an overview of jobs with the highest fluctuations, it is important to examine the level of employee satisfaction and the reasons for leaving, to know their expectations when entering and fulfilling or failing. The adopted criteria and guidelines included in the sustainability strategy oblige managers to address sustainability issues [
54]. However, Parisi and Maraghini [
55] advise that any sustainability-oriented strategies should reflect the level of informality and flexibility of the enterprise’s size and structure.
From an economic point of view, managers have to consider if either accepting staff with the required qualifications or training inadequately qualified staff for the job is more advantageous. The interest of each employer is to know the reasons for the failure of the recruitment process. One of them may be that there is a shortage of qualified and suitable staff on the labor market to offered job positions. In order to occupy a job, a candidate who does not meet the required criteria and has no potential to obtain it during the adaptation period [
56] is accepted. Prior to making such a decision, it is more appropriate to conduct a social network survey, explore work portals, use contacts at secondary or higher education institutions, thoroughly study candidate profiles, check their quality in advance, and verify whether other enterprises have similar problems and cannot fill job vacancies with competent employees.
There are similar studies in this area. The authors Montuschi et al. [
57] present the survey of current job search and recruitment tools focused on applying a computer-based approach to job matchmaking. The study of Pramod and Bharathi [
58] aims at collecting the industry practices and the factors influencing the adoption of social media in recruitment process. Bohnert and Ross [
59] investigated how the content of social networking Web site pages influenced others’ evaluation of job candidates. The research of Al Shehi et al. [
60] evaluates the effects of social networks on the recruitment of professional staff to Ras Al Khaimah’s government and private sector within the United Arab Emirates. The objective of Böhmová and Malinová [
61] is to find out how data presented publicly in Facebook profiles can influence the recruitment process and the decision about hiring new employees. Rajeswari [
62] tested the popularity and effectiveness of the social media sites on one hand and also finding out the reliability and trustworthiness of these websites on the other side in recruitment process. The findings indicate that the quality of social networking sites does attract high number of job applicants through social media networks, thereby resulting in benefits to both employers and employees.
Our survey about the use of social networks for recruitment in comparison with traditional techniques in SMEs is unique and based on the evaluation of Slovak SMEs with domestic and foreign capital participation. The results are evaluated from a database of available information through beta regression analysis. Beta regression analysis is applied within the framework of the use of individual types of social networks for recruiting employees, depending on the company’s capital structure. The uniqueness is also in the visual and numerical clarity of the presented results.
