A social hierarchy perspective on the relationship between leader–member exchange (LMX) and interpersonal citizenship


 Drawing upon contemporary social hierarchy research, the purpose of this study is to integrate a novel theoretical perspective to examine the taken-for-granted conclusions of the relationship between leader-member exchange (LMX) and interpersonal citizenship. We develop theoretically driven arguments and provide evidence of how LMX relates to power and status, the two prominent bases of social hierarchy. The results from our study support our assertion that the quality of LMX relationships provides social information about one's relative standing within a group's informal hierarchy. Specifically, LMX is positively associated with higher levels of perceived power and perceived status. Both power and status serve as important mediators that explain the relationship between LMX and interpersonal citizenship. We also identify the importance of citizenship pressure as a boundary condition for these relationships, finding that citizenship pressure interacts with power and status differently to influence the extent that employees engage in citizenship behaviors.
