PurposeMoral leadership is a common leadership style in Chinese society and is of great significance to Chinese organizations. Unethical employee behavior also widely exists in all kinds of social organizations and brings great harm. The research on the relationship between moral leadership and unethical employee behavior has not been involved yet, but it is important. This paper studies how moral manager (senior leader) leadership trickles down to unethical employee behavior through moral supervisor (employee direct supervisor) leadership, and discusses the moderating effect of LMX and ethical climate.Design/methodology/approachThrough the questionnaire survey of 406 pairs of leaders and employees, and use multilevel path analysis, we test the hypothesis in this paper.FindingsThe research results show that (1) Moral manager leadership is negatively related to unethical employee behavior. (2) Moral supervisor leadership mediates the relationship between moral manager leadership and unethical employee behavior. (3) LMX positively moderates the relationship between moral manager leadership and moral supervisor leadership, and moderates the mediating effect of moral supervisor leadership. (4) Ethical climate positively moderates the relationship between moral supervisor leadership and unethical employee behavior, and moderates the mediating effect of moral supervisor leadership.Originality/valueFirst, this study further proves that moral leadership is a popular positive leadership among the three dimensions of paternalistic leadership that extends its influence to unethical employee behavior. Second, this study traces the source of the moral leadership of employees' supervisors and reveals the action mechanism of how moral manager leadership affects unethical employee behavior. Finally, LMX provides the organizational context of the trickle-down effect and the occurrence of unethical employee behavior.
