Reading the Wind: Impacts of Leader Negative Emotional Expression on Employee Silence.

Employee silence has multiple negative effects on the organization. Studies on the influence of leader negative emotional expression on employee silence are extremely limited, and there are inconsistent findings for the expression of negative emotion among leaders, which highlight the need to explore boundary factors in this field. The purpose of this paper is based on EASI model to examine the impact of leaders' negative emotional expression on employee silence through the perceptions of psychological safety. Moreover, drawing on social exchange theory, this paper proposed a moderated mediation model to explore how leader-member exchange (LMX) moderates the indirect relationship between leader negative emotional expression and employee silence through perceptions of psychological safety. We employed a bootstrapping technique to analyze the hypotheses. This study adopts two-wave surveys and the results shown that leader negative emotional expression triggered employee silence by employees' perceptions of psychological safety. This study also demonstrated that LMX weakens the relationship between leader negative emotional expression and employees' perceptions of psychological safety. Furthermore, LMX weakens the indirect relationship between leader negative emotional expression and employee silence through employees' perceptions of psychological safety. Using multiphase data collection, we found that when LMX is at a low level, the indirect effect of leader negative emotional expression on employee silence through employee psychological safety is stronger. The theoretical, practical implications and future research suggestions are discussed.

Leader Humility and Machiavellianism: Investigating the Effects on Followers' Self-Interested and Prosocial Behaviors.

Existing research on leader humility primarily demonstrates its positive effects. This study challenges this view by proposing the potential negative effects of leader humility on followers' behaviors. Furthermore, this paper employs the person-situation interactionist perspective to extend the research on integrating followers' personality traits and leader humility. Specifically, this study proposed that leader humility triggers their followers' sense of power; moreover, this study wagers that whether followers' sense of power encourages self-interested or prosocial behavior in followers depends on their particular Machiavellian traits. The theoretical model was tested using the time-lagged supervisor-subordinate matched data obtained. Our findings revealed that follower Machiavellianism fosters the relationship between a sense of power and self-interested behavior but it weakens the relationship between a sense of power and prosocial behavior. Thus, this study provides a better understanding regarding the effect of follower personality and leader humility on follower behavioral reactions.
