Given recent prominent ethical scandals (e.g. Tesla, Uber) and the increasing demand for ethical management, the importance of business ethics has recently surged. One area that needs further research regards how ethical leaders can foster followers’ organizational commitment. Drawing upon social exchange theory, the current research proposes that ethical leadership relates to follower affective and normative commitment through perceived organizational support (POS). Moreover, based on self-determination theory, we expected follower psychological empowerment to positively moderate the relationship between ethical leadership and commitment components.

Data were collected using a three-wave study among employees from multiple organizations (N = 297) in Canada. Structural equations modeling and bootstrapping analyses were applied to test the hypotheses.

The results showed that ethical leadership was positively related to follower affective and normative commitment through POS. Furthermore, the relationship between ethical leadership and POS was stronger at high levels of empowerment. This moderating effect extended to the indirect relationship between ethical leadership and commitment components.

This study counts among the few investigations that have examined the mechanisms linking ethical leadership to followers’ organizational commitment and boundary conditions associated with this relationship. Moreover, our findings were obtained while controlling for transformational leadership, which highlights the incremental validity of ethical leadership.

Relying on the theories of substitutes for leadership and psychological empowerment, this study aims to explore how perceptions of customer positive feedback can substitute for managers’ transformational leadership in driving frontline employees’ psychological empowerment and, in turn, task performance.

The authors tested the research hypotheses with frontline employees working in 17 equipment rental stores. Employees completed a questionnaire about customer positive feedback, transformational leadership and psychological empowerment, and supervisors completed a separate questionnaire about employees’ task performance. A total of 178 employee-supervisor dyads formed the final sample of the study.

The results provided support for our hypotheses. Psychological empowerment fully mediated the relationship between transformational leadership and task performance. Moreover, customer positive feedback moderated the indirect relationship between transformational leadership and task performance such that it was significant and positive only when customer feedback was low.

This paper contributes to the service marketing literature by showing that customer positive feedback can substitute for managers’ leadership in helping frontline employees feeling more in control of their work and psychologically empowered. Another useful contribution for practitioners is that customers may have a positive impact on frontline employees’ motivation state, which past research has little explored.

Organizational change is usually stressful and destabilizing for employees, for whom coping with the induced stress is primordial to commit to the change. This paper aims to unravel how and when change recipients can enact different coping strategies and, ultimately, manifest different forms of commitment to change.

We propose a theoretical model that identifies challenge appraisal and hindrance appraisal as two primary appraisals of organizational change that fuel, respectively, proactive and preventive coping strategies and, indirectly, affective and normative forms of commitment to change. Moreover, this framework suggests that coping strategies and commitment are influenced by the secondary appraisal of two vital resources – resilience and POS – allowing individuals to react effectively to primary change-related appraisals. Finally, the relationship between coping strategies and the components of commitment to change is proposed to be moderated by employees' regulatory focus.

Using appraisal theory and conservation of resources theory as guiding frameworks, our integrated model describes the antecedents, processes and boundary conditions associated with coping with the stress of organizational change and how they ultimately influence commitment to it.

This is the first theoretical paper to identify a conditional dual path to disclose the different reactions that change recipients can manifest in response to the stressful aspects of organizational change.

The purpose of this paper is to examine a model linking directive and supportive leadership to group-level helping behaviors via group-level perceived organizational support (GPOS) and collective affective commitment (CAC).

Using data from 115 business units of an international retailer, the authors tested and compared the theoretical model against more parsimonious solutions using χ² difference tests. The hypotheses were examined within a structural model.

The results show that GPOS acts as a mediator in the relationship between leadership behaviors and CAC and between directive leadership and group-level helping behaviors. Supportive leadership is directly related to CAC and group-level helping behaviors.

Implications of these findings for research on supportive and directive leadership are discussed.

This paper proposed a model that examined intermediate linkages between directive and supportive leadership and group-level helping behaviors. In doing so, the authors provide a preliminary response to recent calls for examination of mediators of task-oriented and relations-oriented leadership effects (Judge et al., 2004).

This paper seeks to examine the relationships between affective commitment and organizational citizenship behaviors (OCBs) across four foci: organizations, supervisors, coworkers, and customers. Further, it aims to determine whether relationships among commitments and OCBs involve mediated linkages.

This study relies on matched employee‐supervisor data (n=216). The relative fit of different models representing relationships among commitments and OCBs was examined using structural equations modeling.

Results revealed that commitments to coworkers, customers and supervisors displayed positive relationships with OCBs directed at parallel foci. In addition, commitment to the global organization partially and negatively mediated the relationship of commitments to coworkers and customers to parallel OCBs dimensions. Results also revealed cross‐foci relationships between local commitments and OCBs. Finally, no commitment target was significantly associated with organization‐directed OCBs but the latter were positively related to local OCBs.

The paper demonstrates that multiple commitments and OCBs are involved in a complex net of relationships among which local foci play a critical, and positive, role.

The purpose of this paper is to contrast the foundations of (affective) organizational and career-oriented commitment. Using social exchange theory as a background, organizational commitment is proposed as a mediator between perceived organizational support (POS) and competence development activities and feedback-seeking behavior. Career-oriented commitment, defined as a self-interested orientation toward one’s career, is proposed to mediate a positive relationship between proactive personality and competence development but a negative relationship between proactive personality and feedback-seeking.

Data were collected from 126 employees using one-year time-lagged study in which POS and proactive personality were measured at Time 1, commitment variables at Time 2, and competence development and feedback-seeking at Time 3.

Organizational commitment mediated a positive relationship between POS and competence development but not feedback-seeking. Career-oriented commitment mediated a negative relationship between proactive personality and feedback-seeking but did not mediate the relationship to competence development. Proactive personality exerted direct and positive effects on competence development and feedback-seeking, but had a negative effect on feedback-seeking through career-oriented commitment.

An implication of these findings is that organizations need to reduce the detrimental effects that the proactivity trait exerts on feedback-seeking through career-oriented commitment. One way to do this is to increase the fit between organizational career opportunities and the career expectations of employees with high career-oriented commitment.

This study indicates that social exchange and self-interest motives act as distinct drivers of organizational and career-oriented commitment, respectively, and that these motives have implications for how individuals learn and socialize in the workplace.

The purpose of this paper is to investigate the possibility of curvilinear patterns of relationships between workplace affective commitment and in‐role performance, organizational citizenship behaviors and burnout. As most commitment theories assume strictly linear relations with these outcomes, demonstrating that these positive associations do not hold above some ceiling point in the commitment continuum is potentially important for research and practice.

The possibility of nonlinear relations was examined in a sample of 273 hospital employees.

The results yielded strong support for the authors' hypotheses. Indeed, most of the relations observed (ten of 15) between affective commitment foci and work outcomes were curvilinear, revealing a ceiling to the positive association between commitment and outcomes. Although these results vary in strength across work outcomes and commitment targets, they reveal that affective commitment has negative associations with employee productivity and psychological health at extreme levels.

Methodologically, these results illustrate the need to systematically explore the true nature of relations among constructs, even in areas where it is assumed to be well known. Practically, these results suggest that, ultimately, moderate levels of commitment may be more beneficial than extremely high levels.

The purpose of this paper is to examine the moderating role of passive leadership in the relationships of perceived support from organization, coworkers, and physicians to affective commitment and organizational citizenship behavior (OCB) among hospital employees.

Using a sample of 182 hospital employees and a time-lagged design in which predictors and moderator were assessed at Time 1 and self-reported OCB was obtained 2.5 years later, the authors examined whether passive leadership moderates the relationships of perceived supports to commitment and their indirect effects on OCB.

Analyses indicate that at high levels of passive leadership, the relationship between support from organization and coworkers and commitment is less positive and the relationship between support from physicians and commitment is negative. Moreover, the indirect effect of perceived support from coworkers and physicians on OCB through affective commitment is weaker at high levels of passive leadership.

Although the data used were self-reported, the analyses show that method variance accounted for only 9 percent of the variance among constructs at Time 1. Findings contribute to highlight the boundary conditions associated with perceived support and establish that passive leadership severely limits the beneficial effects expected from support available to employees.

Findings suggest that supervisors should be trained not only on improving positive leadership skills but also on reducing passive behaviors in the face of problems in their teams.

This study extends the understanding of social exchange processes in organizations and invites managers and researchers to look at factors that slow down the development of social exchange relationships with employees.

The purpose of this paper is to shed light on the type of exchange relationship that small business owners establish with their employees. In particular, this study examines how the personality trait of “conscientiousness” among small business owners relates to relational “psychological contracts,” breach and violation that develop between owners and employees.

This was a quantitative survey design conducted in Canada. Participants were 253 employees and the 50 small firm owners for whom they worked.

Results indicate that owner conscientiousness was positively associated with a relational psychological contract with employees and perceived breach mediated a negative relationship between owner-rated relational contract obligations and feelings of contract violation among employees. Owner-rated relational contract obligations also mediated a negative relationship between owner conscientiousness and employee perceptions of breach and violation.

Given the link between conscientiousness and relational contracts, small business owners who get involved in selection and training ought to present to the newly hired employees an accurate picture of their role and job requirements in order to create successful organizations. In addition, less conscientious business owners, through training, should try to develop further skills, such as goal setting and performance appraisal, in order to increase their ability to establish effective relationships (i.e. relational contracts).

The current study is an initial attempt toward a better understanding of exchange relationships in small firms, thus strengthening the links between organizational behavior and small business research. It also contributes a quantitative perspective on issues that have typically been explored qualitatively.

The purpose of this paper is to examine the links between work stressors, perceived stress, emotional exhaustion, and workplace aggression, using the traits of negative affectivity and external locus of control as individual moderators.

Data were collected using a survey questionnaire among 477 blue-collar workers from a Tunisian manufacturing company.

Results indicate that perceived stress mediates a positive relationship between work stressors (quantitative workload, role ambiguity, and interpersonal conflicts) and emotional exhaustion. Moreover, the relationship between quantitative workload and interpersonal conflicts and perceived stress is stronger among individuals with high levels of negative affectivity. Similarly, the relationship between quantitative workload and perceived stress is stronger at high levels of external locus of control. Finally, emotional exhaustion mediates a positive relationship between perceived stress and interpersonal and organizational aggression.

The findings suggest that Tunisian organizations may reduce perceived stress and aggressive behavior among blue-collar workers through reducing quantitative workload, role ambiguity, and interpersonal conflicts. Moreover, specific training programs, job redesign, and formal mentorship that provide employees with improved social skills can also be recommended as soon as early signs of frustration or intentions to misbehave appear. Finally, leadership development practices may help supervisors better manage workplace stressors and reduce the occurrence of workplace aggression.

The current study is an initial attempt to look at an integrated model of stress and aggression among blue-collar workers in Tunisia. While some of the findings are consistent with the literature, others might reflect the unique aspects of the Tunisian culture.
