This research investigates the intricate relationship between mental health and workplace behaviors, specifically focusing on organizational citizenship behavior (OCB) and counterproductive work behavior (CWB). OCB and CWB are recognized as significant components of organizational behavior, with employees displaying these behaviors when they experience either job satisfaction or perceived threats. However, the factors influencing the choice of these behaviors remain elusive. This study contends that emotional states, shaped by the complex interplay of individual mental health, organizational climate, and culture, play a pivotal role in determining an employee's propensity to engage in OCB or CWB. Anxiety, stress, and depression are natural emotional responses to workplace situations, and they can both trigger and be triggered by OCB and CWB. This article aims to comprehensively investigate the impact of these emotional states on OCB and CWB behaviors. Furthermore, it explores the application of the conservation of resources (COR) theory in understanding these dynamics. The article underscores the necessity for further research in this area to enhance our comprehension of the intricate relationships among mental health, emotions, and workplace behaviors. This study contributes to the growing body of knowledge at the intersection of psychology and organizational behavior.
