The South African Police Service (SAPS) has implemented a shift system in which police officers are scheduled to work for four consecutive days, resulting in a total of 48 hours per week. The implementation of the 12-hour shift pattern has been found to have an adverse effect on police officers. Consequently, this appears to have a detrimental effect on police effectiveness. Studies investigating the effects of the 12-hour shift have revealed that this work schedule significantly influences the reaction time, sleep patterns, and overall health of police officers, thereby impacting their performance. This study aims to provide a qualitative analysis of the effects of the 12-hour shift on police performance at Pretoria Central (SAPS) Police Station in Gauteng Province, South Africa. Data was collected from eight (8) individuals from the SAPS, namely at Pretoria Central Police Station, using semi-structured interviews. The participants have suggested that officials in the SAPS should evaluate the existing shift structure and increase the deployment of police officers at the police station. This would help alleviate the workload of the officers and enhance service delivery.

The rapid growth in civil aviation operations in recent years has raised expectations from flight attendants. Their duties have been intensified, and flight attendants have become subject to physical and mental fatigue due to irregular sleep, inadequate rest time, and long working hours. This study investigates the causes and effects of fatigue among flight attendants of a Turkish airline company through a self-administrated questionnaire. The survey is run online by 152 flight attendants. The results show that flight attendants have trouble falling asleep before flight duty. Before night flights and during layovers, the sleep duration is dramatically low. The results also reveal that factors related to scheduling, i.e., long duty days, night flights, and consecutive working days, play an essential role in fatigue. Thus, airline companies should revise their scheduling practices. In balancing work and social life, men struggle more than women, and married flight attendants have more difficulty than single ones. The findings provide valuable insights for airline companies and policymakers to seriously manage fatigue-related factors to ensure the safety of aviation operations and the well-being of flight attendants.
