1. Introduction
Universities may not be excluded from companies of high economic force. They cannot be underestimated, especially in terms of their production. Indeed, this is because universities are centers of knowledge generation and sharing and play a very important role in solving the world’s problems and ensuring a sustainable tomorrow by providing awareness and new knowledge. Given this power, it is important to take a hard look at whether these corporate giants are indeed upholding their end of the social compact. The failure to study the impact of these companies on society represents a great risk, such as severe environmental degradation. Nevertheless, corporations have promised significant job creation and an overall improvement in social welfare [
1]. In fact, this might be needed to achieve a positive impact on sustainability issues, which will lead to long-term benefits for companies and society. Therefore, there is a need to move companies toward better social and environmental performance. This means being prepared and able to face the most difficult environmental challenges society faces, such as climate change, habitat destruction, and water scarcity. This is where the role of corporate social responsibility (CSR) should be considered essential.
Ogbonna and Harris [
2] showed that the interaction between organizational citizenship behavior (OCB) and transformational leadership style (TLS) affects the level of corporate performance. More importantly, this is due to the fact that corporate sustainability is mortgaged by TLS and OCB, which are linked to inherent human values [
3], meaning that the needs of the organization and all stakeholders in terms of economic, social, and environmental justice can be met—this is called CSR. That is, there is a need to integrate human values and institutions through CSR to achieve overall sustainability. Eventually, these practices are associated with OCB in terms of social identity theory [
4], in which the worker identifies themselves through their company.
Meanwhile, it has become clear that corporate leadership needs to spark the drive for a positive impact on the environment, which will also have long-term benefits for companies and society [
3]. Companies need to move toward better social and environmental performance. This means being prepared and able to face the most difficult environmental challenges society faces, such as climate change, habitat destruction, and water scarcity [
5]. In fact, this is where the role of CSR becomes synonymous with corporate citizenship and corporate sustainability [
6]. CSR is a self-organizing model to be socially responsible [
7]. This means that the company operates in a sustainable manner within itself, society, and the environment [
6]. Sustainability initiatives give hope for continued existence and life. Central to this is the integration of institutions and values. However, many institutional sustainability approaches relate to interaction and compliance, rather than creative competency to meet the needs and demands of stakeholders [
3]. Paying more attention to CSR practices and OCB is essential.
OCB improves sustainability performance for three main reasons: first, it builds the capabilities and values to effectively overcome internal and external threats facing a company, and secondly, it significantly enhances long-term performance, growth, and profitability. Thirdly, and most importantly for our study, it has a role in the development of CSR [
3]. The importance of CSR lies in the fact that resources cannot be consumed without taking into account their consumption, as resources are not endless, which means that companies, society, and the environment are interconnected [
5]. This means that focusing on one aspect of sustainability, such as the economy, is futile and harmful to the survival of the companies themselves, as it is necessary to combine both institutions and human values. That is why ISO 26000 was issued to help companies implement CSR [
8]. It provides specific guidance, because the nature of CSR still focuses on quantity more than quality. These standards target all types of organizations, regardless of their activity, size, or location. Nevertheless, there is international consensus regarding these standards, which is due to the fact that many key stakeholders from all over the world contributed to them.
According to Shephard and Guiney [
9], this necessarily applies to university institutions around the world, including universities in Jordan. Such institutions are always striving for competence, growth, and excellence to cope with the dynamic pace of changes. In fact, according to Nejati et al. [
10], the world-leading universities are committed to social responsibility, which in the end generates economic, social, and environmental benefits (i.e., to contribute to the three pillars of sustainable development defined by the United Nations Conference on Environment and Development in 1992) [
11]. In addition, organizations such as companies or universities are frequently responsible for severe environmental degradation [
12].
It further applies to universities because higher education institutions can cause “significant environmental impacts” [
13]. This is due to their large size, expressive movement of people and vehicles, high consumption of materials, and strong development of complex activities; from many perspectives, they may even be considered “small towns” [
14]. More importantly, universities are centers of knowledge generation and sharing. They play a very important role in solving the world’s problems and ensuring a sustainable tomorrow by providing awareness and new knowledge. Many organizational decision-makers were once students in universities, and it is important to know how universities regard CSR. This necessarily means that universities should be responsible toward society and their stakeholders. In fact, to strengthen this social contract, which allows such organizations to continue their operations [
15], they need to be socially responsible. Fortunately, as discussed by Leal [
16], there is a high level of acceptance regarding the importance of pursuing sustainability—including its economic, social, and environmental dimensions.
However, while some literature claims a strong relationship between TLS and OCB, OCB and CSR, and TLS and CSR [
17], there is still a gap in the study of the mediation effect of OCB between TLS and CSR, as none of the previous studies have addressed this issue.
1.1. Statement of the Problem
In Jordan, the growth of the educational industry has been impressive in the past two decades. Jordan has 29 universities that collectively generate thousands of graduates each year, from mixed cultures [
18], in many specialties, including engineering and medicine, for the local market and for neighbouring countries, especially the Gulf countries [
19]. This means that the prosperity of the universities sector in Jordan and its impacts on sustainability issues merit closer attention. This might potentially impact the sector’s performance in general, as its performance is the outcome of the interaction of many factors, among which is the interaction between leadership style, OCB and CSR in particular, which is the main focus of this study.
However, as recent studies have confirmed that TLS and OCB have become a problem that significantly hinders the sustainability of higher education development and performance, and confirmed that OCB can allow the enterprise to meet multiple stakeholders’ needs and demands around sustainability, the researchers chose to investigate the impact of leadership in CSR through OCB mediation.
In this regard, as TLS has been highlighted as a critical determinant of OCB [
2], and OCB as a determinant of CSR [
3,
4], there remains a limited understanding of how these major factors interact. Therefore, the aim of this paper is to investigate this gap; assuming that although TLS may directly impact CSR, the indirect impact of TLS on CSR would be much greater and more significant when mediated by OCB [
17].
Nevertheless, the significance of this study comes from the fact that despite the existing research conducted on the interaction between TLS, OCB, and CSR, none has focused on investigating the mediating effect of OCB between TLS and CSR. For this reason, this study investigated the impact of TLS on CSR through the mediation of OCB. Moreover, the significance of this research lies in being new in the Jordanian context, offering a deeper insight and understanding into the relationship between OCB, TLS, and CSR. Most of the existing studies that have been conducted in the particular context of universities in Jordan are mostly descriptive in nature. More importantly, this study attempts to build a valid model, with an empirical proof that fits the Jordanian context, that can be used to measure the direct and indirect impact of TLS on CSR through the mediation of OCB.
1.2. Literature Review
1.2.1. Leadership and Leadership Styles
Leadership is considered a basic concept that implies influence over followers, and is involved in the development of organizational theory in management. Leadership is mostly conceptualized within the behavioral domains [
20]. According to Goleman et al. [
21], there has been an increased interest over time in the aspects related to practices of leadership from a quality point of view. Leaders are interested in achieving success through satisfying the goals and objectives of their organizations. In addition, people in general, and leaders or managers in particular, tend to possess leadership skills inherently and then learn certain leadership characteristics and skills to manage with challenges that may arise in various situations throughout life, assisting them in successfully overcoming such challenges and obstacles. Thus, individuals or organizations that do not have well-developed, skilled leaders may face insurmountable challenges.
Taking into consideration the widely accepted axiom that leaders are not exclusively “born leaders” but are, rather, most often “grown” or “developed”, researchers have worked to develop instruments and tools to measure styles of leadership that involve certain behavioral traits associated with good leadership. According to Yusra et al. [
22], the following are the styles of leadership one adopts: autocratic leadership (the boss), democratic leadership (all-inclusive), laissez-faire or free rein leadership (chilled-out), bureaucratic leadership, charismatic leadership (motivational), paternalistic leadership (family-oriented), transactional leadership, servant leadership, entrepreneurship leadership styles, the coaching style, cross-cultural/diverse leadership, the leader exchange style, situational leadership, strategic leadership, facilitative leadership, the participative leadership style, the visionary leadership style, and transformational leadership. However, people as leaders adopt different styles for different kinds of jobs according to the circumstances. In our study, the focus will be on TLS, as its primary focus is to make change happen in ourselves, others, groups, and organizations, which fits our goals. Therefore, the framework that is at the base of this research is the transformational leadership theory. According to Yusra et al. [
22], this theory encourages, motivates, and supports employers, often involves recognizing and rewarding people for their good work, and inspires their team to work together towards a common target.
In TLS, the leader identifies changes that are needed and creates a vision with commitment. Transformational leadership consists of many components. Pillai et al. [
23] studied four of these components: The first component, charisma (idealized influence), is defined as “followers trust and identify emotionally with the leader”. The second component, inspiring motivation, means that followers receive emotional symbols and appeals to w focus on achieving goals, and having high expectations. The third component, intellectual stimulation, refers to “promoting the ability to question the ways of doing things”. The last factor, individualized consideration, means that “tasks provide employees with learning opportunities”. Wagude et al. [
24] added in their study the concept of idealized behavior, which is defined as the need for change and a vision and to mobilize employees to effectively perform beyond expectations. Moreover, Castillo et al. [
25] conducted a study that focused on the associations between coaches’ value priorities and their transformational leadership behaviors, exploring the potential mediation versus moderation effect of two alternative variables in this relationship: perceived club pressure or an autonomy supportive environment. The study concluded and highlighted the importance of identifying the value base on which to develop transformational leadership programs in order to enhance positive experiences in the sport domain.
1.2.2. Organizational Citizenship Behavior (OCB)
OCB is recognized as an individual’s behavior that collectively and effectively increases the performance of any particular organization. However, although the ethical impact of OCB in organizations is known, its causal influence on employees has not been fully investigated [
26]. In their study, Cohen [
27] expressed their opinions about the importance of OCB in organizations, and emphasized the role of OCB in the effective performance of organizations.
According to Igor et al. and Khan [
28,
29], most scholars define OCB as a latent variable consisting of five components: conscientiousness, civic virtue, courtesy, sportsmanship, and altruism. Altruism refers to the readiness of workers to help their colleagues in their tasks in an organization. Courtesy is the respect expressed by employees to colleagues. Sportsmanship refers to the readiness of employees to accept less optimal conditions and the presence of a positive attitude, without making complaints. Civic virtue refers to the improvement of a company. Conscientiousness is behavior that is not required by the organization.
OCB can be argued to include activities that are extra and above an employee’s formal job requirements [
30]. Smith et al. and Yildiz [
31,
32] emphasized that OCB does not depend on incentives. The study by Akinbode [
33] did not show a positive association between some factors among participants, including age, gender, tenure, management level organization, demographic variables, and OCB. For example, Okediji et al. [
34] did not show any role for gender in OCB. Kim [
35] showed that OCB does not depend on financial returns, but on the perception of employees of their personal values in their organization. However, other studies have showed that females are more likely to exhibit OCB than males, and OCB increases with age. Moreover, Broucek [
36] evaluated the reasons behind student OCB, and found warmth to be the strongest predictor of OCB.
Nusair et al. [
37] provided a good understanding of how TLS is related to innovative behavior. They demonstrated that TLS is a good predictor of innovative behavior. In addition, they found that the place of work significantly impacts attitudes and innovative behavior. Moreover, Tareq [
38], in his research into three banks operating in Jordan, considered the role of TLS in terms of its four components—inspirational motivation, individual consideration, idealized influence, and intellectual stimulation—and their impact on organizational performance. The results showed that leaders need to focus on inspirational motivation, individual consideration, and intellectual stimulation to improve the results of organizational performance, while idealized influence was found not to contribute significantly to this outcome. Moreover, Akif and Sahar [
39] investigated the impact of three leadership styles of academic staff on modifying students’ behavior in Jordanian universities. They showed that the academic staff using a democratic style most effectively modified students’ behavior.
Alsheikh and Sobihah [
40] emphasized how organizational commitment, leadership style, and organizational culture influence OCB, with the moderating role of job satisfaction in the relationship. Moreover, Abd and Cohen [
41] examined the interaction between values, social exchange variables, and OCB and in-role performance. The results showed that openness to change was related to altruistic OCB, while self-transcendence was related to in-role performance. More importantly, they showed that employees’ behavior can be better understood through these values and variables in the workplace.
1.2.3. Corporate Social Responsibility (CSR)
The literature includes many studies related to different aspects of CSR in conjunction with leadership style and OCB. Nejati et al. [
10] questioned whether world-leading universities are concerned about CSR and, if they are, to what extent they are committed to their social responsibilities. The findings showed that world-leading universities are committed to their social responsibility, and they provide sufficient information on most of the core areas of CSR. Oo et al. [
42] examined organizational pride as the underlying psychological mechanism explaining the relationship between CSR perception and OCB. It was found that organizational pride mediated the CSR perception–OCB relationship. In addition, collectivism orientation strengthens the CSR–pride relationship, while person–organization fit strengthens the OCB–pride relationship. Cingöz et al. [
43] examined the relationships among CSR, OCB, and ethical leadership. The findings indicated a significant and positive relationship between CSR and ethical leadership. However, no significant relationship was found either between OCB and CSR, or OCB and ethical leadership. Gao and He [
44] proposed a trickle-down model and examined the mediating role of supervisors’ ethical leadership and the moderating role of perceived organizational distributive justice in the CSR-OCB relationship. Their empirical findings demonstrated that CSR had a positive effect on employee OCB, as mediated by supervisors’ ethical leadership. In addition, this mediation effect was found to be moderated by perceived organizational distributive justice, such that the mediation relationship was stronger when perceived organizational distributive justice was lower than when it was higher. Wang [
45] proposed and tested a sequential mediation model in which CSR promoted organizational prestige. They found that organizational prestige increases employees’ collective organizational identification and, consequently, enhances their collective OCB at the firm level. Mohammad and Nik [
46] investigated the implementation of CSR programs and their impact on OCB among employees. It was found that employee behavior OCB is also dependent on the organization’s commitments toward non-business social agendas, and that the commitment seems to correlate positively with employees’ own altruistic behaviors among themselves. Ong et al. [
47] developed a CSR sensitivity framework that explains how task significance, a micro-level job characteristic, can sensitize employees to their organizations’ macro-level CSR efforts, thereby strengthening the association between CSR and OCB. It was found that CSR and task significance interact to predict OCB, where CSR is more positively associated with OCB among employees who report higher task significance than among those who report lower task significance. Iqbal et al. [
48] examined the effect of authentic leadership on OCB, as well as examining the mediating mechanism of CSR on the aforementioned relationship. It was found that authentic leadership positively predicts OCB. Furthermore, it was found that CSR positively mediates the relationship between authentic leadership and OCB.
1.3. Development of the Hypotheses
The literature indicates a positive correlation between different types of leadership, such as ethical leadership, transformational leadership, and transactional leadership, and CSR [
49,
50]. In addition, the current literature shows a positive and significant correlation between TLS and OCB [
51,
52,
53,
54]. However, the psychological mechanisms underlying such relationships are still unclear, as there is the potential for a missing link with some mediating effects. However, some studies have emerged to investigate certain mediation roles, such as that of Iqbal et al. [
48], who studied the impact of authentic leadership on OCB and the mediating role of CSR. However, studies related to the link between TLS and CSR with the mediating effect of OCB are scarce. Based on the above literature, it is suggested that TLS plays a vital role in influencing CSR practices through the mediation of OCB. Therefore, we hypothesized that:
Hypothesis 1 (H1): The measurement instruments present adequate properties regarding the reliability of the scores and evidence of the validity of the internal structure;
Hypothesis 2 (H2): TLS directly impacts CSR practices through OCB;
Hypothesis 3 (H3): TLS indirectly impacts CSR practices through OCB.
4. Discussion and Conclusions
In this study, we investigated how transformational leadership style (TLS) indirectly impacts corporate social responsibility (CSR) practices through the mediation of organizational citizenship behavior (OCB). This was done after testing the properties regarding the reliability of the scores and evidence of validity of the internal structure of the measurement instrument. For the first hypothesis, we found that the three instruments needed to be modified, wherein the initial 20 items of the five components of TLS, 24 items of the 5 components of OCB, and the 4 items of the single component of CSR practices were not all accepted. Thus, the hypothesis was reconsidered to include 14 items for the 5 components of TLS rather than the original 20 items, and 14 items for the 5 components of OCB rather than the original 24 items, and 3 items for the single component of CSR practices rather than the original 4 items. The re-specified factor loadings were all accepted. In addition, 31 items remaining from the 48 items of TLS, OCB, and CSR practices were shown to be accounted for by the TLS-OCB-CSR practices model, which means that each item loads only onto the TLS or OCB or CSR practices constructs, additionally, the TLS-OCB CSR practices hypothesized model showed a relatively good fit with the sample data. However, with the deletion of the mentioned items, this supports H1.
The results of the SEM support hypothesis H2, in which we anticipated that TLS would have a positive direct effect on employees’ CSR practices. More importantly, results support H3, in which we anticipated that TLS would have a positive indirect effect on employees’ CSR practices through the mediation of OCB. TLS appeared to have a total significant effect on CSR practices equal to 0.122, which is due to both the direct (unmediated) significant effect (equal to 0.060) and the indirect (mediated by OCB’s significant effect for TLS on CSR practices; 0.062). These results confirm four major issues. First, they show the direct effect of OCB on CSR practices, which is very important to the indirect effect of TLS on CSR practices, because if this were zero, no mediation would happen at all. Second, they show that there is a significant direct effect for TLS on CSR practices. Third, and most importantly, they show an indirect effect for TLS on CSR practices through the mediation of OCB, and that the magnitude of the indirect effect of TLS on CSR practices through the mediation of OCB is larger than that of the direct effect.
Thus, it is evident from the analysis that TLS in all of its components, as perceived by employees, has significant effects on CSR practices through the mediation of OCB in all of its components. Indeed, this can support the importance of (TLS) and be supported by Yusra et al. [
22] who claimed that transformational leadership style is one of the most implemented styles because it has integrity, defined and clear goals, encourages clear steps to communication and being expressive. However, as the direct effect of TLS on CSR is lower in effect and in significance than the indirect effect of TLS on CSR through the mediation of OCB, this means that the impact of TLS on CSR practices can only be better predicted by the mediation of OCB, and of course by computing and adding both the direct and the indirect effect of TLS on CSR together. Eventually, this may lead leaders to highly focus on instilling OCB, should they be willing to achieve and encourage CSR practices on their employees. By so doing, organizations can only achieve their objectives in carrying out their duties while achieving ethical, environmental, and humanitarian purposes. Based on these results, improving CSR practices will lead to achieving sustainability in higher education corporations in Jordan. This is supported by Anderson and Cavanagh and Matten [
1,
6], who argued that organizational effectiveness and sustainability performance requires OCB, which, once improved, causes CSR practices to improve directly. Nevertheless, one can conclude that OCB and CSR practices are integrated in addressing many of the sustainability issues, as OCB builds capability and values in an organization to face endogenous threats, and CSR practices build capability and values to face exogenous threats, both meeting multiple stakeholders’ needs and demands. This is supported by the fact that building a sustainable world requires consideration of the intersection of leadership and ethics.
4.1. Implications
This study has several practical implications. First, we found a positive indirect effect of the transformational leadership style on corporate social responsibility through the mediation of the organizational citizenship behavior. This result could help leaders to perceive the advantages of being part of ethically imposed corporate social responsibility practices. Moreover, as supported by Dhiman [
3], leaders could become more aware in reconsidering and associating business with ethical, philanthropic, and environmental issues, and in shaping their organizations and being aware that this requires them to act as a model for employees of being engaged in corporate social responsibility practices. Hence, organizations should pay more attention to their leadership styles, and ensure it instills the organizational citizenship behavior to achieve corporate social responsibility practices for the good of sustainability that would reflect positively to stakeholders, employees, customers, suppliers, and the community, leading to long-term business success. Moreover, this study will assist future researchers with further examining the relationship between the transformational leadership style, corporate social responsibility and the organizational citizenship behavior.
4.2. Contributions
This research contributes to this field by providing a validated model in the Jordanian context, that is capable of measuring TLS, OCB, and CSR practices and their impact on each other, especially the indirect effect of TLS on CSR practices through the mediation of OCB. In addition, this research contributes to the literature on TLS-OCB-CSR practices by increasing academic knowledge concerning the mediation of OCB between TLS and CSR practices; no research has so far been conducted on this mediation topic, giving this research its value and originality. This means that researchers, in their future studies in this field, will now be aware of the probable missing link between leadership style and CSR practices.
4.3. Limitations
It is possible that the findings are unique to any of the demographic variables which have not been checked. For example, this study showed that males dominated females with a 241 (61.5%)/151 (38.5%) ratio. Therefore, future studies are needed to consider such limitations. This is in addition to considering moderator or mediating variables, such as demographic variables, in achieving better CSR practices.
