High work-related stress negatively impacts workers’ health and productivity in the Nigerian petroleum industry. Supervisors in the Nigerian petroleum industry who lack strategies to reduce work-related stress significantly lose worker health and organizational productivity. Grounded in person-environment fit theory, the purpose of this qualitative multiple case study was to explore strategies Nigerian petroleum industry supervisors use to manage work-related stress. Participants were six supervisors who have successfully used strategies to reduce work-related stress in the Nigerian petroleum industry. Data were collected from semistructured interviews and internal company documents relevant to reducing work-related stress and analyzed using thematic analysis. Three major themes emerged: (a) impact of work-related stress, (b) strategies successfully used to manage work-related stress, and (c) challenges impacting effective work-related stress management. The key recommendations include training workers and supervisors on stress management, defining minimum conditions of service for workers, having an organizational policy on stress management, and collaboration among managers, employees, and clients on work-related stress management. The implications for positive social change include the potential to improve employee health and well-being and enrich families in communities.
