Abstract: The study examines the impact of critical organizational factors (organizational culture and excellent leader performance) on public relations professionals’ overall job satisfaction by focusing on testing the joint mediating effects job engagement and trust could generate. A national online survey of 838 public relations professionals working in a variety of organizations was used as the empirical data to test the relationships in a proposed conceptual model. Results confirmed the strong impact organizational culture and leader performance could have on public relations professionals’ job engagement, trust, and job satisfaction. More importantly, results revealed the significant joint mediating effects of engagement and trust on professionals’ job satisfaction, when supportive organizational culture and excellent leader performance were presented. The study concludes with research and practical implications.
