As cybercrimes continue to proliferate, researchers and professionals worldwide are exerting efforts to identify factors that may increase the risk of data breaches. To contribute to this scholarly endeavor, we posit that employee turnover is a potential factor for data breaches. Therefore, the objective of our research is to empirically investigate the impact of employee turnover on data breaches. Grounded in fairness theory, our research explains how perceptions of unfair departure (either voluntary or involuntary) can prompt former employees to engage in retaliative activities such as cyberattacks. Through a unique panel dataset, we aim to offer novel insights into how employee turnover can increase the risk of data breaches.
