1. Introduction
In recent times, corporate ethics has emerged as a crucial aspect for businesses, spurring extensive exploration by both academics and practitioners alike in the realm of corporate social responsibility (CSR) [
1,
2,
3]. CSR encompasses a diverse array of interpretations and can be generally defined as the aggregation of strategies and practices implemented by organizations to augment their economic, social, and environmental performance while concurrently addressing the multifaceted needs of stakeholders, such as employees, consumers, local communities, governments, and the environment [
4,
5]. Although numerous investigations have been conducted to analyze the impact of CSR on organizational performance, the outcomes have remained ambiguous [
6,
7,
8,
9]. Certain studies propose that CSR initiatives function as a strategic “investment,” offering organizations a competitive edge [
10,
11,
12]. Conversely, a number of scholars have argued that allocating resources toward social responsibilities may be tantamount to a “cost” that can impede operational effectiveness [
13,
14]. In an attempt to harmonize these divergent viewpoints, researchers have examined various underlying mechanisms and situational factors that moderate the relationship between CSR and organizational outcomes [
4,
6,
9,
15,
16,
17,
18]. Despite numerous inquiries into the effect of CSR on organizational outcomes, various gaps persist within the current literature [
6,
7,
8].
First, although earlier research has delved into the ramifications of CSR on organizational members, the majority of these studies have primarily focused on individuals’ perceptions and attitudes. These encompass various aspects, such as identification with their organization, organizational commitment, job satisfaction, organizational trust, work meaningfulness, intrinsic motivation, and employee engagement [
19,
20,
21,
22,
23,
24,
25,
26]. Conversely, there has been a comparatively limited focus on employee behaviors [
6,
7,
8,
27]. Although perceptions and attitudes represent essential outcomes at the individual level within an organization, they are likely to ultimately manifest themselves in behaviors [
6,
7,
27]. Consequently, we postulate that employee behavior exhibits a stronger association with various organizational outcomes in comparison to perceptions and attitudes, rendering it imperative to investigate the impact of CSR on member behaviors.
Second, previous research has insufficiently investigated the impact of CSR on employee knowledge-related behaviors [
6,
7,
27]. While research has established the positive influence of CSR on various organizational outcomes, the impact of CSR on employees’ knowledge-sharing behavior remains underexplored. Knowledge-sharing is a critical determinant of innovation and organizational performance [
27,
28]. Owing to the considerable impact that knowledge possesses in generating value-added products and services, which subsequently exerts a substantial effect on a firm’s competitive advantage [
29,
30], exploring how CSR influences employees’ knowledge-related behaviors is essential [
31,
32]. In light of the significance of knowledge-sharing behavior, it is essential to investigate CSR’s influence on knowledge-sharing behavior.
Third, relevant to the second research gap in existing CSR literature, there has been an insufficient examination of the mediators and moderators that impact the links between CSR and knowledge-related behaviors [
6,
7,
27]. As recognizing the mediators and moderators can provide a comprehensive understanding of this connection [
6,
7], it is crucial to explore the mediating and moderating variables in the CSR knowledge-related behaviors link.
To address these research gaps, this study investigates the underlying procedures (mediators) and contextual variables (moderators) present in the link between CSR and knowledge-related behaviors. Among various knowledge-related behaviors, we focus on knowledge-sharing behavior, which is defined as the extent to which an employee disseminates knowledge, encompassing the act of exchanging information, skills, expertise, and knowledge among individuals or groups within an organization [
33]. The profound significance of knowledge-sharing in the contemporary business landscape cannot be understated. This important practice, as elucidated by Wang and Noe [
33], encompasses the dissemination of information, skills, expertise, and knowledge among employees or groups within an organization. When successfully implemented, knowledge-sharing cultivates an environment conducive to continuous learning, innovation, and growth, consequently empowering organizations to capitalize on their intellectual assets and achieve a sustainable competitive advantage [
30].
This paper proposes that CSR can increase the quality of employee knowledge-sharing behavior through the sequential mediating effect of perceived organizational support (POS) and organizational commitment (OC); in other words, CSR would sequentially increase the degree of POS and OC, which ultimately enhances the extent of knowledge-sharing behavior. Also, an ethical climate would function as a positive moderator in the link between CSR and POS.
Our purpose is to find the mechanisms through which CSR affects employees’ knowledge-sharing behavior. The contributions of this study are as follows. First, by exploring the influence of CSR on knowledge-sharing behavior, it expands the understanding of the factors that encourage employees to engage in knowledge-sharing activities within organizations. Second, by examining the mediating roles of POS and organizational commitment, this study offers an elaborated view of the underlying mechanisms through which CSR influences employee knowledge-sharing behavior, enriching the theoretical underpinnings of the CSR literature. Third, by investigating the moderating effect of ethical climate, the study highlights the significance of fostering an ethical work environment to enhance the impact of CSR on employee perceptions and behavior. Lastly, the rigorous methodology employed in this study, involving a longitudinal survey design with a diverse sample of Korean panelists, lends credibility to its findings and their implications for both research and practice. By shedding light on the critical mechanisms linking CSR initiatives with employee knowledge-sharing behavior, this research offers valuable insights for organizations aiming to foster a collaborative and innovative work environment through socially responsible practices.
By investigating these relationships in a South Korean context and using a longitudinal research design with three time points, this study contributes to the generalizability of the findings and offers implications for both researchers and practitioners in the field of CSR, organizational behavior, and human resource management.
5. Discussion
Drawing on various theoretical foundations, the present study investigates the relationship between CSR and employee knowledge-sharing behavior, examining the sequential mediation role of POS and organizational commitment as well as the moderating role of ethical climate. Six hypotheses were developed to explore the sequential mediation effect of POS and organizational commitment on the association between CSR and knowledge-sharing and the moderation effect of ethical climate on the connection between CSR and POS, respectively. To address potential common method bias issues, data were collected from 204 South Korean employees at three separate time points. The findings provide strong evidence that CSR activities positively impact employees’ knowledge-sharing behavior, an effect that is sequentially mediated by both POS and organizational commitment. Additionally, the study reveals the positive moderating role of ethical climate in the relationship between CSR and POS. By integrating multiple theoretical perspectives, this research not only contributes to the existing literature but also offers valuable insights for organizations aiming to enhance knowledge-sharing through the strategic implementation of CSR initiatives.
5.1. Theoretical Implications
The theoretical implications of this study on the nexus between CSR and employee knowledge-sharing behavior make a noteworthy contribution to the extant literature by addressing several research lacunae and proffering novel insights into the underlying mechanisms that sculpt this relationship. By scrutinizing the sequential mediation of POS and organizational commitment, this investigation advances our comprehension of the intricate interplay among CSR initiatives, employee perceptions, and knowledge-sharing behavior.
First, this research enriches the literature by incorporating social identity theory, organizational citizenship behavior theory, and social cognitive theory to elucidate how CSR initiatives can bolster employees’ willingness to participate in knowledge-sharing behavior. By amalgamating these theoretical viewpoints, the study presents a comprehensive framework for understanding the impact of CSR on employees’ knowledge-sharing behavior (Hypothesis 1).
Second, this study extends the CSR literature by examining the mediating function of POS and organizational commitment in the CSR–knowledge-sharing nexus (Hypothesis 5). Drawing upon stakeholder theory and the conservation of resources theory, the investigation provides an innovative understanding of how CSR activities can augment employee POS (Hypothesis 2). Moreover, social exchange theory and social identity theory are employed to explicate the connection between POS and employees’ organizational commitment (Hypothesis 3). These theoretical foundations enrich our grasp of the mediating mechanisms linking CSR initiatives with knowledge-sharing behavior.
Third, this research sheds light on the moderating capacity of ethical climate in the CSR–POS relationship (Hypothesis 6). By incorporating social identity theory and social exchange theory, this study deepens our understanding of the boundary conditions that can either intensify or attenuate the influence of CSR initiatives on employee perceptions and attitudes.
5.2. Practical Implications
The practical implications of this study on the relationship between CSR and employee knowledge-sharing behavior furnish invaluable insights for top management teams and organizational leaders tasked with designing and implementing CSR initiatives that not only contribute to societal well-being but also cultivate a positive work environment that encourages employee knowledge-sharing.
First, this study underscores the importance of devising and executing CSR initiatives that effectively communicate the organization’s commitment to social responsibility. As the findings indicate, CSR activities can augment knowledge-sharing behavior among employees (Hypothesis 1) and POS (Hypothesis 2), which, in turn, can bolster employees’ organizational commitment (Hypothesis 3). By investing in substantive CSR initiatives, top management teams can engender a sense of pride and identification among employees, which can result in increased knowledge-sharing and collaboration within the organization.
Second, this research accentuates the role of POS in fostering employee commitment and knowledge-sharing behavior. Top management teams and leaders should be cognizant of the potential benefits of providing employees with adequate resources, support, and recognition for their contributions. By enhancing POS, organizations can fortify employees’ organizational commitment (Hypothesis 3) and stimulate knowledge-sharing behavior (Hypothesis 4).
Third, the study emphasizes the significance of cultivating an ethical climate within the organization. As the findings suggest, ethical climate positively moderates the relationship between CSR and POS (Hypothesis 6). Top management teams should prioritize the development of an ethical work environment that advocates transparency, fairness, and adherence to moral values. By fostering an ethical climate, organizations can further reinforce the positive effects of CSR initiatives on employee perceptions and attitudes.
In summary, the contributions of this study proffer practical insights for top management teams and leaders in organizations endeavoring to leverage the benefits of CSR initiatives. By concentrating on the design and implementation of efficacious CSR activities, enhancing POS, and nurturing an ethical work environment, organizations can promote employees’ commitment and knowledge-sharing behavior, ultimately contributing to a more innovative and collaborative organizational culture.
5.3. Limitations and Suggestions for Future Studies
Notwithstanding the considerable contributions of this investigation to the understanding of the interplay between CSR and employee knowledge-sharing behavior, it is imperative to recognize each study’s limitations and opportunities for future research.
First, we ought to consider the fact that the research sample was primarily sourced from South Korean companies, thus potentially preventing the applicability of the results to a wider array of cultural milieus. Consequently, in order to corroborate the findings and bolster their generalizability, subsequent inquiries should replicate the study across various settings, including an assortment of countries, industries, and organizational structures.
Second, the data collection method employed a self-reported survey, which might introduce common method bias. Future studies could consider using alternative data collection methods, such as observational data, supervisor evaluations, or secondary data sources, to verify the findings and mitigate potential biases.
Third, the study focused on the sequential mediation effect of POS and organizational commitment as well as the moderation effect of ethical climate. However, other potential mediators and moderators might also impact the relationship between CSR and knowledge-sharing behavior. Future research should explore additional variables, such as trust in the organization, psychological empowerment, or the role of leaders in shaping the relationship between CSR and knowledge-sharing.
Finally, the study relied on cross-sectional data collected at three distinct time points, which may not fully capture the dynamic nature of the relationship between CSR and knowledge-sharing. Future studies could employ longitudinal or experimental designs to investigate the causal relationships between CSR initiatives, POS, organizational commitment, ethical climate, and knowledge-sharing behavior over time.
