This study examines the relationships of servant leadership to organizational commitment, voice behaviors, and antisocial behaviors. Adopting a multifaceted approach to commitment, we hypothesized that servant leadership would be positively related to affective, normative, and perceived sacrifice commitment, but unrelated to few alternatives commitment. We further hypothesized that affective commitment would be positively related to voice behaviors, controlling for the other commitment components, and would mediate a positive relationship between servant leadership and voice behaviors. Similarly, we hypothesized that normative commitment (...) would be negatively related to antisocial behaviors, controlling for the other commitment components, and would mediate a negative relationship between servant leadership and antisocial behaviors. These predictions were tested using matched data from a sample of 181 Canadian customer service employees and their managers. Results largely supported the above predictions. Importantly, affective commitment mediated a positive relationship between servant leadership and voice behaviors. Yet, while servant leadership was positively related to normative commitment and the latter was negatively related to antisocial behaviors, the indirect effect of servant leadership on these behaviors through normative commitment was nonsignificant. Theoretical implications and future research directions are discussed. (shrink)
