Resumo

Work shift is one of the factors that influence job satisfaction, especially for jobs that require 24-hour service for seven days, such as those in healthcare and law enforcement. In various parts of the world, police officers are required to have work shifts because their services are needed 24 hours a day, 7 days a week. This study explores the effect of work shift patterns on job satisfaction among police officers in the Njombe Region, Tanzania, focusing on the patterns and types of shifts. The study was grounded in insights from circadian rhythm theory, motivation theory, and the hierarchy of needs, which aim to explain factors influencing motivation and job satisfaction in relation to shift schedules. Out of 384 police officers in Njombe, the researchers randomly selected 169 respondents for this study using Yamane’s formula. Data were collected from 169 respondents using structured questionnaires and analysed using descriptive statistics, t-tests, and regression. Findings confirm that fixed shifts and morning shifts are more preferable and have a significant impact on increasing job satisfaction compared to rotating and frequent night shifts. Therefore, a work shift is a strong predictor of job satisfaction. The value of p of the fixed shift was significant, and the regression coefficient of fixed shift was +0.36, while that of rotating was -0.27, validating the argument that fixed shift has a positive effect, while poorly managed rotating shift has a negative impact on job satisfaction among police officers. Moreover, the regression output shows that shift pattern is a strong determinant of job satisfaction among police officers, fixed shift pattern improves satisfaction (B=0.65, p<0.001); however, frequent night shift affects satisfaction negatively (B=-0.270, p<0.001). The impact of age and years of service has a significant positive effect, as p>0.05 exhibits a positive, statistically insignificant effect. Also, based on T-test results, there was a high level of satisfaction among officers on the fixed shift (p < 0.001) and the morning shift. These findings emphasize the vital significance of scheduling practices in improving workforce well-being and reducing dissatisfaction associated with night work. The study recommends that there is a need for shift policy reform that takes into account fixed scheduling, reduces the frequency of night duty, and ensures that fitness and creativity programs are incorporated into the policy to maintain higher energy levels. Based on the results, the study concluded that stable and predictable work schedules promote psychological well-being, efficiency, and effectiveness in operations, increase employee satisfaction, and reduce absenteeism and employee turnover. Findings serve as a basis for critical evidence in promoting workforce management within the Tanzanian police force. By aligning officers' demands with best practices in human resources, it is straightforward to enhance service delivery, performance, and the well-being of officers. Therefore, it is paramount for governments and administrators to ensure that work schedules are effectively managed, allowing police officers to perform their critical duty of protecting the community and its assets, as well as providing public safety.
