Coworkers’ interpersonal justice and team citizenship behaviors: mediation of social exchange and identity and moderation of extraversion

Purpose The purpose of this study is to examine the effect of coworkers’ interpersonal justice (defined as the extent to which one is treated by coworkers with dignity, courtesy and respect) on team citizenship behaviors. More precisely, the authors first test the mediating role played by both team-member exchange and team identification in this relationship. Further, they examine the moderating role of extraversion in these two mediating mechanisms. Design/methodology/approach Based on 134 subordinate–supervisor dyads, the authors conducted moderated multiple mediation analysis. Findings The results of this study showed that, for highly extraverted employees, coworkers’ interpersonal justice positively influences team citizenship behaviors because of an exchange relationship of better quality among the team members. In contrast, for employees with low or medium levels of extraversion, the positive effect of coworkers’ interpersonal justice on team citizenship behaviors is explained by their higher identification with the team. Practical implications This paper holds important implications for management practice in teamwork environment. Given coworkers' interpersonal justice role in determining team citizenship behaviors, the findings of this study highlight the importance of establishing a work culture where each employee treats others fairly. Originality/value Overall, these findings indicate that, depending on the level of employees’ extraversion, mechanisms grounded in the social exchange and the social identity perspectives act as complementary mechanisms in the team-focused justice–citizenship behaviors relationship.
