In a sample of 522 police officers and staff in an English police force, we investigated the role of authoritarian leadership in reducing the levels of employee ethical voice (i.e. employees discussing and speaking out opinions against unethical issues in the workplace). Drawing upon uncertainty management theory, we found that authoritarian leadership was negatively related to employee ethical voice through increased levels of felt uncertainty, when the effects of a motivational-based mechanism suggested by previous studies were controlled. In addition, we found that the negative relationship between authoritarian leadership and employee ethical voice via felt uncertainty is mitigated by higher levels of benevolent leadership. That is, when authoritarian leaders simultaneously exhibit benevolence, they are less likely to cause feelings of uncertainty in their followers who are then more likely to speak up about unethical issues. We discuss theoretical and practical implications of the findings.

Using social learning theory, the job demands-resources model and idiosyncrasy credit theory, the present study casts additional light on the explanatory mechanisms underlying the effects of service leadership on service performance. We examine employee work engagement as an important mediator of this relationship and explore the moderating role of leader task-based professional and managerial skills on the indirect relationship between service leadership and service performance via work engagement. Drawing upon 903 leader–follower dyads nested in 187 teams, with data collected from two sources, we find that after controlling for transformational leadership, follower work engagement mediates the relationship between service leadership and follower service performance. Furthermore, the results support the moderating role of leader task-based professional skills, but not of managerial skills. Specifically, the indirect effect of service leadership on service performance via work engagement is stronger when leaders display high levels of task-based professional skills. Theoretical and practical implications of these findings are discussed.

We investigated how abusive supervision influences interactions between third-party observers and abused victims and hypothesized when and why third parties react maliciously toward victims of abusive supervision. Drawing on the theory of rivalry, we predicted that third-party observers would experience an “evil pleasure” (schadenfreude) when they perceive a high level of rivalry with the victims of abusive supervision and that the experienced schadenfreude then would motivate third parties to engage in interpersonal destructive behaviors (i.e., undermining, incivility, and interpersonal deviance) toward the victims. We further proposed that such malicious reactions would be attenuated if groups have a high level of cooperative goals. Results based on one experimental study and two time-lagged field studies lend support to our propositions.

Drawing upon two independent samples from mainland China, we propose and investigate the deterrence function of leadership behavior focused on control. We suggest that controlling leadership, specifically, authoritarian leadership, deters employees’ deviance under certain conditions. That is, authoritarian leadership thwarts employees’ interpersonal deviance behavior when leaders send clear signals of potential punishments of non-compliance by showing low leader benevolence, and when employees are highly dependent on the leaders for important work resources. Results from two independent studies largely support our key propositions. Overall, these results add to the range of possible impacts that a leader can play in decreasing employee deviance. Theoretical implications and directions for follow-up research are discussed.

Drawing upon self-concept and social-information processing perspectives, we theorize and test a model linking ethical leadership with ethical voice via ethical value internalization and integrity identity. In two field studies ( N = 972 and N = 765, respectively) of police officers and staff in the United Kingdom and an online three-wave study ( N = 448), we investigate the mediating role of ethical value internalization and integrity identity in the relationship between ethical leadership and ethical voice. Study 1 uses time-lagged data and demonstrates ethical leadership to be positively related to followers’ ethical value internalization, which in turn enhances their integrity identity and ethical voice. The serial mediation effect of the relationship between ethical leadership and ethical voice via employees’ ethical value internalization and integrity identity is also significant. Further support for our hypotheses is provided using multisource data (Study 2) and a three-wave cross-lagged design (Study 3). Theoretical and practical implications are discussed.
