Taking the new generation employees as the study objects, this paper explores the influencing mechanism of service-oriented leadership on the new generation employees' pro-social illegal behaviors. It constructs a theoretical model of the relationship between service-oriented leadership, psychological safety and pro-social illegal behaviors and conducts an empirical analysis of the data from the questionnaire survey of 283 employees born after 1980 or 1990 in Guangdong, Yunnan, Hainan and other places. The findings show that the service-oriented leadership has a positive impact on the pro-social illegal behaviors of the new generation employees, that the service-oriented leadership has a positively impact on psychological safety, that psychological safety has a positive impact on the pro-social illegal behaviors of the new generation employees, and that psychological safety is playing an mediating role between the service-oriented leadership and the pro-social illegal behaviors of the new generation employees.
