Transformational leadership and employee communication behaviors : the role of communal and exchange relationship norms

Purpose: This study aims to examine the effects of transformational leadership on employees' internal (i.e. voice) and external (i.e. megaphoning) communication behaviors and to explore the mediating role of employees' communal and exchange relationship norms with their organization. Design/methodology/approach: An online survey was conducted with full-time employees working in various industry sectors in the USA. Findings: Transformational leadership significantly increased employees' voice behaviors and their positive and negative megaphoning behaviors. Communal relationship norms exerted a significant mediation effect on employees' communicative behaviors and exchange relationship norms had positive impacts on employees' megaphoning behaviors. Originality/value: This study is among the first attempts to test the effect of transformational leadership style on employees' communicative actions within and outside of a company and the mediating role of exchange-communal relationship norms.
