The COVID-19 pandemic has created tremendous challenges for organizations’ corporate social responsibility (CSR), communication, and relationship management with internal stakeholders such as employees. This study conducted an online survey of 466 employees working for large Chinese corporations during the pandemic. A structural equation model based on insights from expectancy violation theory was used to examine how negative violation valence increases employees’ turnover intention as mediated by uncertainty, CSR cynicism, and distrust. The survey results showed that employees’ negative violation valence positively influenced their uncertainty about their organizations’ CSR activities, which fostered their cynicism about CSR and distrust of their organization. Employees’ CSR cynicism increased their distrust toward their organizations, which increased their turnover intention. The theoretical and practical implications of the study are discussed as well.
