Ethical Climate and Whistleblowing Intentions: Testing the Mediating Roles of Public Service Motivation and Psychological Safety Among Local Government Employees

Local governments in several developing countries are plagued with corruption. This study draws attention to the role of organizational ethical climate in promoting whistleblowing intentions among local government employees and asks whether public service motivation (PSM) and perceptions of psychological safety mediate this relationship. Based on survey data of 365 employees in 40 local governments in Thailand, our multilevel analysis confirms that the relationships between ethical climate and internal and external whistleblowing intentions were indirect. In particular, psychological safety was found to play a mediating role at both the individual and organizational levels of analysis, whereas the mediating role of PSM was observed only at the individual level. The findings also revealed the presence of “collective PSM” at the organizational level, which in turn helped to facilitate external whistleblowing intentions. This research unveils the importance of individual- and organization-level factors in the whistleblowing decision-making process.
