The purpose of this study is to explore the mechanisms by which leader humor affects followers’ change-oriented organizational citizenship behavior. Specifically, we examine the mediation effect of team commitment in the leader humor–change-oriented organizational citizenship behavior link and whether it varied by leader Machiavellianism. Using multi-sourced data from the four battalions of the Republic of Korean Army, our findings show that team commitment mediated the positive relationship between leaders’ affiliative humor and followers’ change-oriented organizational citizenship behavior. Furthermore, the mediated relationship was stronger when leader Machiavellianism was lower. On the other hand, we found no support for the negative relationship between leaders’ aggressive humor and followers’ change-oriented organizational citizenship behavior. Theoretical and practical implications are discussed.
