Researchers in public administration for the past few decades are interested in exploring how public service motivation (PSM) influences turnover intentions. This study puts the theory of PSM to test in a different cultural context and explores the relationship between PSM and leadership on turnover intentions via person-organization fit (P-O fit) in public sector employees from Trinidad and Tobago and Barbados. Results of structural equation modeling indicate a significant negative relationship between senior leadership and turnover intentions, but a positive and significant relationship between PSM and turnover intentions. The positive effects of PSM on turnover are different from the Western models of motivation in the public sector. Results also show a partial mediation of PSM and turnover intentions via P-O fit. This research highlights the need for studying leadership, motivation, and turnover by utilizing a cultural and value lens to examine and understand employee behaviors in public organizations outside of North America.
