Internal control plays an important role in managing the risks of banking system activities. Controllers are always under pressure from control activities due to the bank’s diverse activities. The resignation of internal controllers is relatively common in commercial banks. It is also a matter of concern for the banking and finance industry, which coordinates economic resources for the country, especially when the internal control period occurs again with the pandemic. The study aims to explore the turnover intention of internal controllers in the context of COVID-19 in Vietnamese commercial banks. The study uses the convenience sampling method to collect data from 339 respondents who are working or worked as internal controllers in commercial banks. The study was surveyed in 2023. The study uses quantitative methods for exploratory factor analysis. Ordinary least squares process the data to test the hypotheses. Some factors affect the turnover intention of internal controllers, such as occupational awareness, employment conditions, office environment, and career opportunities, in the context of COVID-19. The result is a useful resource for researchers to comprehensively understand issues related to the turnover intention of internal controllers in the banking industry. The study supports managers of commercial banks in planning the strategic objectives of human resource stabilization for the stable growth of the banking system.
