Why and when workplace friendship has a differentiated effect on relationship norms and helping behavior: a relationship motivation theory approach
摘要
Existing scholarship acknowledges workplace friendships as complex relationships integrating exchange and communal interaction patterns governed by distinct norms. However, critical gaps remain in understanding how these relational complexities differentially influence organizational citizenship behaviors, particularly regarding contextual boundary conditions. This study advances a motivational framework examining how workplace friendships shape helping behaviors through dual normative pathways. We propose that perceived relationship motivations determine whether workplace friendships activate communal norms (fostering proactive helping) or exchange norms (promoting reactive helping). Using multi-wave field surveys (Study 1, N = 615) and experimental methods (Study 2, N = 214), results demonstrate that autonomous relationship motivation perceptions strengthen the link between workplace friendships and communal norms, enhancing proactive helping. Conversely, controlled relationship motivation perceptions amplify the connection between workplace friendships and exchange norms, increasing reactive helping. These findings resolve theoretical ambiguities about normative pluralism in workplace relationships, identify motivational antecedents of norm activation, and establish boundary conditions for relationship-driven citizenship behaviors.
