Abstract
Excessive job stress is a growing concern in many organizations, leading to reduced employee productivity and well-being. This study explored the mediating role of work engagement in the relationship between job stress and employees’ productivity at Adama Beverage Limited, Adamawa State, Nigeria. Using a descriptive survey design, data were collected from 161 employees out of a population of 270, selected through stratified random sampling and determined using the Taro Yamane formula. A structured questionnaire was used, and data were analyzed using percentages and multiple regression analysis. The findings revealed that job stress significantly reduces productivity and negatively affects work engagement, while work engagement positively influences productivity and mediates the effect of stress. The study concluded that excessive job stress leads to reduced efficiency, increased absenteeism, and low work enthusiasm. It recommended that Adama Beverage Limited implement stress management strategies such as employee assistance programs, relaxation techniques, and workload redistribution. Management should also enhance engagement by promoting career development, recognizing employee efforts, and fostering a supportive work culture.
