Workplace stress has increasingly been reported to be an issue of concern in the global, regional and local workforce. Several studies have contributed to knowledge on stress especially on effects of stress in several specific sectors leaving prevalence level and causes of stress with scanty information. This paper applied Conservation of Resources (COR) theory to address two study objectives mainly; to determine the prevalence of stress among employees and to examine the causes of stress among employees at Chemba District Council. The study employed a Cross-sectional research design and collected data from 14 key informants and from 60 respondents through interview and questionnaire methods respectively. The study collected both qualitative data and quantitative data which were analysed by content analysis method and descriptive statistics method respectively. The findings reveal that a good number of employees accounting to 80% have at least experienced stress whereby, huge workload, work deadlines, family challenges, financial challenges and job insecurity are significantly causing stress among employees at Chemba District Council. It is concluded that, the revealed prevalence of stress among employees as a result of several stressors needs supportive policies and mental health initiatives to address adverse effects. It is recommended that Chemba District Council should implement stress management programs like workshops, mindfulness training and relaxation techniques to help employees cope with stress.
