Abstract
Drawing on the logic of positive organizational scholarship and anchored in an integration of moral licencing and social cognitive theories, we examine social-relational processes relating affiliative citizenship behaviour to promotive and prohibitive voice. Based on respondents from private sector organizations, Study 1 examines why affiliative citizenship behaviour relates to these two types of voices. Results of path analysis reveal affiliative citizenship behaviour to indirectly relate to both the promotive and prohibitive voices through the serial mediation of moral credits and voice self-efficacy. Study 2 draws on a sample of firefighters and their team leaders to replicate as well as extend the findings of Study 1 by examining a boundary condition of the preceding relationships. Results of path analysis replicate the indirect effect of affiliative citizenship behaviour on promotive and prohibitive voice through the preceding social relational pathways. Additionally, the findings extend those of Study 1 by showing these relationships to be conditional upon servant leadership such that they are stronger when servant leadership is low rather than high. Specifically, servant leadership enhances the voice self-efficacy of those low (but not high) in moral credits leading to promotive and prohibitive voice.
