Fatigue, stress, and burnout among South African law enforcement officers under the 12-hour shift system: An integrative review

The South African Police Service (SAPS) relies extensively on a 12-hour shift system to maintain operational coverage across a high-crime environment. While this scheduling model offers logistical advantages, accumulating evidence suggests it exacts a significant toll on the occupational health of officers. This study presents a comprehensive secondary data analysis examining the prevalence, antecedents, and consequences of fatigue, occupational stress, and burnout among South African law enforcement officers operating under the 12-hour shift system. This integrative review synthesises evidence from peer-reviewed journal articles, official reports, and empirical studies identified through targeted searches of relevant databases and institutional repositories published on shift work, fatigue, stress, and burnout in policing. A total of twenty-five sources were reviewed and analysed using thematic synthesis within the Job Demands-Resources framework. The reviewed literature consistently suggests that extended shift durations are strongly associated with sleep deprivation, heightened allostatic load, emotional exhaustion, depersonalisation, and reduced personal accomplishment. These outcomes translate into impaired decision-making, increased use-of-force incidents, elevated absenteeism, and accelerated staff attrition. Organisational, policy, and leadership-level recommendations are advanced, including the adoption of evidence-based shift rotation schedules, mandatory wellness programmes, and supervisory training in fatigue risk management. The manuscript concludes by calling for primary longitudinal research to address persistent gaps in the South African policing context.
