The current research examines the consequences of supervisors' overtime hours on subordinates. Drawing upon the stressor‐emotion model of counterproductive behaviors, we argue that supervisors' overtime hours positively relate to abusive supervision behaviors through negative emotions, which in turn undermine leader–member exchange relationships. We further posit that this process is exacerbated among subordinates with a strong relational self‐concept. Multisource multilevel data collected from an organizational sample of 181 employees and longitudinal data from 416 employees from multiple organizations support our predictions. This research indicates that the consequences of working overtime extend beyond supervisors, as subordinates may be negatively affected when their supervisors work long hours. We discuss implications for both theory and practice.
