Although prison officers experience working conditions associated with work–life conflict, little research has explored this issue. This study draws upon the work–home resources model to investigate relationships between working conditions (demands and experiences of aggression) and time-based, strain-based, and behavior-based work–life conflict in U.K. prison officers (N = 1,682). Associations between working conditions, work–life conflict, and emotional exhaustion were also examined. Two recovery behaviors (affective rumination and detachment) were considered as potential moderators of associations between working conditions and emotional exhaustion. High levels of all work–life conflict dimensions were found, which were related to working conditions and emotional exhaustion. Some evidence was found that higher rumination and lower detachment exacerbated the positive association between both job demands and aggression and emotional exhaustion. The implications of the findings for the well-being and professional functioning of prison officers are discussed, together with key areas for future research.
