<p>Research on faculty members’ work-nonwork conflict experiences has grown in importance in recent years. Yet, it has primarily focused on work-family conflict. Their work-leisure conflict experiences have been neglected. Considering work-leisure conflict as a job stressor, this study investigates the influence of work-leisure conflict on faculty members’ work engagement through work-related affective rumination. Additionally, this study examines the moderating role of neuroticism in this relationship. The conceptual framework is based on the stressor-detachment model. Data were collected from 478 faculty members. The findings revealed that (1) work-leisure conflict is negatively associated with work engagement and positively associated with work-related affective rumination; (2) work-related affective rumination negatively affects work engagement; (3) work-related affective rumination has a mediating role between work-leisure conflict and work engagement; (4) neuroticism moderates a positive relationship between work-leisure conflict and work-related affective rumination; (5) neuroticism moderates the indirect relationship between work-leisure conflict and work engagement through work-related affective rumination.</p>
