With the increasing prevalence of team-based work in organizations (Kozlowski & Bell, 2013; Mathieu, Maynard, Rapp, & Gilson, 2008), managers have to delegate power to their employees and encourage them to be more autonomous, responsive, and proactive at work. As a result, empowering leadership, which is defined as "sharing power with a view toward enhancing employees' motivation and investment in their work" (Zhang & Bartol, 2010, p. 107), has received burgeoning scholarly attention in the leadership literature. Whereas prior studies focusing on the consequences of empowering leadership have demonstrated the positive effect of empowering leadership on employee work performance, including not only routine task performance

Past research suggests that interactional justice plays a pivotal role in facilitating high-quality leader-member exchange (LMX), with downstream implications for employee performance. However, the broader context in which these effects unfold has received scarce attention. Drawing from deontic justice and social exchange theories, we suggest that interactional justice differentiation is an important contextual moderator of the link between interactional justice and LMX. Specifically, we argue that high interactional justice differentiation attenuates the link between interactional justice and LMX, in turn influencing the effects of interactional justice on employee task and creative performance. Results from two studies employing both experimental and multisource, multilevel survey designs provide convergent support for the hypothesized model. We conclude by highlighting several key theoretical and practical implications of our findings.

Purpose – Prior researches have indicated that leadership had an important impact on employee creativity. However, the authors know little about the link between the dark side of leadership-abusive supervision, and employee creativity, as well as its underlying mechanisms. Combining psychological safety theory and social identification theory, the purpose of this paper is to examine the relationship between abusive supervision and employee creativity and the mediating role of psychological safety and organizational identification between abusive supervision and employee creativity. Design/methodology/approach – The authors conducted a multi-source and time-lagged data collection. At Time 1, team members evaluated abusive supervision and psychological safety, and at Time 2, team members evaluated organization identification, and team leaders evaluated members’ creativity. Abusive supervision, psychological safety were evaluated at first stage and organizational identification, creativity were evaluated at second stage, being conducted 2-4 weeks later after the first stage. Finally 423 participants completed two waves of data collection. Findings – The results suggested that, abusive supervision had negative effects on psychological safety and organizational identification, and psychological safety partially mediated the relationship between abusive supervision and organizational identification, and organizational identification fully mediated the relationship between psychological safety and creativity, and the negative effect of abusive supervision on employee creativity was mediated by psychological safety and then by organizational identification. Originality/value – This study identifies and examines the mechanism underlying the effect of abusive supervision, and suggests that psychological safety and organizational identification are two important mediators of the complex relationship between abusive supervision and employee creativity. Therefore, this study not only re-examines the inconsistent effect of abusive supervision on employee creativity, but also represents the first attempt at integrating the psychological safety perspective and social identification theory to study employee creativity and offers important implications for theory development.

Drawing on the componential model of creativity (Amabile), we examined how shared leadership and a formally appointed leader's transformational leadership jointly cultivate team creativity in two studies. We conducted an experiment with a sample of 109 undergraduate students (32 teams) enrolled in a business plan competition (Study 1) and a field survey based on multisource, time‐lagged data collected from 251 full‐time employees working on 64 research and development teams (Study 2). The results from both studies revealed that shared leadership enhanced team members’ individual creative self‐efficacy and individual creativity, which in turn improved team creativity. Moreover, the results from Study 2 showed that a formally appointed leader's use of different transformational leadership behaviors had different impacts on individual and team creativity. Individual‐focused transformational leadership strengthened the positive effect of shared leadership on team members’ average individual creativity, whereas group‐focused transformational leadership facilitated the translation of teams with high average individual creativity into teams with high levels of team creativity. The theoretical and practical implications of the findings are discussed.

Drawing from self-concept and implicit leadership theories, we propose a multilevel model to examine whether, why, and when self-sacrificial leadership motivates followers’ affiliative and challenging citizenship behaviors in China. Data from 329 full-time employees in 83 work groups provide support for the hypothesized model. Specifically, we demonstrated that self-sacrificial leadership was positively related to followers’ relational self-concept constructs of leader identification and leader-based self-esteem, which had differential, downstream implications for followers’ two types of citizenship behavior. Whereas leader identification was found to mediate the positive relationship between self-sacrificial leadership and affiliative citizenship behavior only, leader-based self-esteem mediated the positive relationships of self-sacrificial leadership with both affiliative and challenging citizenship behaviors. We further demonstrated individual power distance orientation as a significant cultural contingency in the above mediation relationships, which were found to exist among followers with low rather than high power distance orientations. We conclude by discussing the theoretical and practical implications of these findings.
