This study was conducted to find out the effect of occupational stress on job performance at Aspet A. Company Limited. The study employed descriptive approach. The sample size adopted was one hundred and nine through the help of convenience sampling techniques. Descriptive analysis factors like frequency tables, mean scores and percentages were generated, and their interpretations thoroughly explained and interpreted. Based on the findings of the study, it was clear that there are multiple causes of stress which have physical, emotional and psychological effects on employees at the company. The study revealed that stress relation with workforce marital status, education, and working experience was negative. However, the study found out that stress among employees does enhance their job performance in a positive manner (r = 0.348, sig. value=.000). This gives the indication that as employee stress increases, their job performance also tends to increase and vice versa. This section concludes on the premise that stress to an extent enhances job performance at the company. It was therefore recommended that management of the company must come up with an overall coping strategy policy on stress reduction focusing on employees’ marital status, education and working experience at the workplace. Also, the study recommended that tasks should be assigned taking into much consideration the marital status, education and working experience of employees in order not to overburden them with so much work and negatively affect them. Lastly, the research recommended the need to look at any further study concerning the effect of occupational stress on job performance to either confirm or refute the outcome of this study.
