Does Leader Humor Influence Employee Voice? The Mediating Role of Psychological Safety and the Moderating Role of Team Humor

Past research indicates that leader humor can bring many positive outcomes; however, its influence on employee voice has been largely neglected. We propose that leader humor can influence employee voice behaviors (i.e., promotive and prohibitive) via the mediating role of psychological safety. Drawing upon the substitutes for leadership theory, we further propose that team humor could moderate the influence of leader humor. Based on the latent moderated mediation structural equation modeling analysis, we found that employees whose leaders used humor more frequently perceived higher levels of psychological safety and in turn engaged in more promotive and prohibitive voice behaviors. Moreover, the indirect effects of leader humor were found to be more pronounced when teams have a low level of humor. On the other hand, leader humor has less influence on employee voice when teams have a high level of humor, which provides support for the leadership substitutes argument. Theoretical and practical implications are discussed.

Is Ethicality Itself a Boundary Condition for Ethicality: The Complementary Role of Employees’ Exchange Ideology and Moral Awareness in Restricting the Effect of Ethical Leadership in Reducing Workplace Deviance

Ethical leadership (EL) seems to be effective in reducing workplace deviance, questions remain as to whether its benefits are consistent across all situations. Specifically, whether its effectiveness remained in an already ethical environment. In this investigation, we explore two important boundary conditions of ethical leadership that are themselves related to ethicality. We first explore how employees’ moral awareness (MA) may lessen the need for ethical leadership. Drawing on substitutes for leadership theory, we suggest that when individuals already possess a heightened level of moral awareness, ethical leadership’s role in reducing deviant actions may be reduced. We also contended that Employees’ Exchange Ideology - the strength of an employee’s belief that the work effort should depend on treatment by the organization- also reduces EL effectiveness. This norm of reciprocity may not be ethical, as the leader’s positive or negative efforts towards employees may divert them from doing what is morally right to reciprocate. However, not all individuals value reciprocity to the same degree, hence higher Employees’ Exchange Ideology (EEI) may be another boundary condition of EL effectiveness. We conceptualize this framework by modifying Gok et. al. (2017) model to add Employees’ Exchange Ideology as a moderating factor along with Moral Awareness. Workplace Deviance was measured by organizational directed deviance (OD) and supervisor directed deviance (SD). Empirical validity was established by conducting a survey using a close-ended questionnaire. Data was collected from 310 employees working in different organizations in Pakistan and was analyzed using confirmatory factor analysis and structured equation modeling. Results indicated a significant negative complementarity of EEI, in the effect of EL on both dimensions of workplace deviance. This suggested, higher EEI seems to limit the effect of EL on organizational and supervisor-directed deviance. However, the moderating effect of MA was not substantiated for Pakistan. EEI also seems to have a positive effect on both OD and SD, while, SD seems to have a positive effect on OD. Interestingly, EL seems to be causing rather than reducing both OD and SD in the Pakistani environment.

Servant leadership and nurses’ upward voice behavior in an Egyptian hospital: Does prosocial motivation matter?

BACKGROUND: Servant leadership can be viewed as a leadership theory that stresses personal integrity and focuses on protecting and promoting the interests of others. OBJECTIVE: This article investigates whether the relationship between servant leadership and nurses’ upward voice behavior in an Egyptian hospital is contingent on prosocial motivation. Invoking substitutes for leadership theory, we propose that the relationship between servant leadership and nurses’ upward voice will be attenuated when nurses have a strong desire to protect and promote the well-being of others. METHODS: Using a sample of 341 nurses working in a large governmental hospital in Egypt, this proposition was tested using PROCESS Macro for SPSS. RESULTS: The results revealed that the relationship between servant leadership and nurses’ upward voice was stronger for those lower in prosocial motivation than for those higher in prosocial motivation. CONCLUSION: These results were explained through communal impulsion which adds a new insight into Greenleaf’s theory of servant leadership. Overall, the results of the study shed new light on the conditions through which servant leadership enhances upward voice behavior in an Egyptian hospital.

The dynamic interaction between high-commitment HRM and servant leadership

Purpose Based on social exchange theory and the substitutes for leadership theory, this paper aims to investigate whether an organization’s high-commitment HRM strategy can substitute for the effect of servant leadership in promoting employees’ affective commitment, psychological empowerment and intent to remain with the organization. Design/methodology/approach This study’s hypotheses were tested with moderation and mediation analyses conducted on a sample of 172 Chinese employees. Findings The results show significant negative interaction effects between high-commitment HRM systems and servant leadership, such that high levels of one will reduce the positive effect of the other on affective commitment and psychological empowerment. Further, the effects of high-commitment HRM systems and servant leadership on turnover intentions are mediated through affective commitment and psychological empowerment. Finally, support was found for a mediated moderation model where the negative interaction effect between high-commitment HRM systems and servant leadership on turnover intentions is mediated through affective commitment. Practical implications The results of this study can help practitioners identify alternative means to influence employees’ positive attitudes and work motivation when implementing high-commitment HRM systems is not feasible for the organization. Originality/value This study contributes to the leadership literature by providing evidence supporting the substitutes for leadership theory and describing the specific conditions under which this theory is valid, as well as contributing to the HRM literature by examining the dynamic interaction of HRM and leadership.

Giving Rise to Creative Leadership: Contextual Enablers and Redundancies

Creative leadership plays a key role in realizing the competitive advantage of creativity for organizations, yet little is known about the contextual factors that give rise to creative leadership. We propose a model that includes enabling contextual variables that facilitate individuals with the motivation to lead for creativity to engage in creative leadership. In addition, building on substitutes for leadership theory, contextual redundancies that reduce the necessity for creative leadership as a means for realizing creative outcomes are proposed. This model provides new insights about the role of contextual enablers and redundancies at the organizational and external environmental levels of analysis for creative leadership. Theoretical and practical implications of this model are also discussed.

Ethical Leadership, Work Meaningfulness, and Work Engagement in the Public Sector

This study responds to recent calls for research on how and why ethical leadership is related to employee outcomes. Drawing on self-concept–based theory and substitutes-for-leadership theory, the study examines both the mediating and moderating role of work meaningfulness on the relationship between ethical leadership and work engagement. Using a sample of Egyptian public hospital nurses, the results of structural equation modeling (SEM) revealed that work meaningfulness partially mediated the relationship between ethical leadership and engagement. Furthermore, the results showed the positive relationship between ethical leadership and work engagement was stronger for employees who experienced lower rather than higher levels of meaningfulness. Thus, public sector organizations need to put emphasis on nurturing ethical leadership and stimulating employees’ sense of work meaningfulness. However, they need to be aware that, sometimes, they may not be able to get “double the benefits” when they invest in developing both.

Mindfulness as substitute for transformational leadership

Purpose Transformational leaders spark the intrinsic motivation of employees, thereby stimulating their extra-role performance. However, not all employees are lucky enough to have a transformational leader. The purpose of this paper is to investigate to what extent mindfulness can function as a substitute for transformational leadership. By being attentive to and aware of what is taking place in the present, mindfulness provides employees with a source of intrinsic motivation that lies within the person, thereby possibly making employees less dependent on transformational leadership. Design/methodology/approach An online survey was used to collect data of 382 employees working in diverse sectors in the Netherlands. Findings Moderated mediation analyses indicated that mindfulness partly compensates for a low levels of transformational leadership in fostering intrinsic motivation and in turn extra-role performance, thereby providing evidence for the substitutes for leadership theory. Moreover, the findings extend previous research on the contribution of mindfulness to in-role performance by showing its additional value for intrinsic motivation and extra-role performance. Research limitations/implications Despite the use of validated measures and the presence of an interaction effect, common-source bias cannot be out ruled completely. Practical implications Since mindfulness can be developed, the results suggest a training intervention to make employees less dependent on their leaders for their motivation. Originality/value This paper is the first to show that mindful people are more resilient against the absence of transformational leadership. Given the frequent changes in management layers in organizations, knowledge about resources for individual resilience and self-management is sorely needed.

High involvement management practices as leadership enhancers

Purpose – Based on the high-involvement management model and the Substitutes for Leadership theory, the purpose of this paper is to evaluate the moderating role of high-involvement management practices on the relation between managers’ transformational leadership and employees’ affective organizational commitment. Design/methodology/approach – Data were collected from employees of a large Canadian financial firm. Questionnaires were sent out and 219 received, representing a response rate of 63.3 percent. The hypotheses were tested using multiple regressions analysis with moderation effects. Findings – The results show three statistically significant interactions between transformational leadership and high-involvement management practices. More specifically, information sharing and power sharing practices acted as leadership enhancers, while skill development practices served as a leadership substitute. Practical implications – The results of this research could help immediate supervisors adjust their leadership strategies to their organizations’ HRM practices, and also guide top managers in choosing practices that can support these supervisors. Originality/value – This study contributes to the literature on leadership by considering how contextual factors may affect the influence of transformational leadership and by integrating HRM practices within the substitutes for leadership framework.
