Abstract: The purpose of this study was to find out the work-related stress and job performance of employees. Using a descriptive research design, the study involved seventy-eight (78) employees as respondents. A self-made questionnaire, which was validated and reliability tested, served as the primary tool for collecting data. The research focused on how work-related stress—arising from factors such as workload, work environment, and interpersonal relationships—affects the job performance of employees. Findings revealed that most employees experienced a moderate level of stress in their workplace. However, even though stress was present, it did not significantly affect how employees performed their jobs. A comparative analysis showed no significant relationship between the levels of work-related stress and job performance, suggesting that stress alone does not directly determine employee output or efficiency. This could be due to various reasons, including individual coping strategies, workplace support systems, or a strong sense of job commitment. This paper emphasizes the importance of understanding the nature of work-related stress and its potential effects—not just in terms of performance, but also employee well-being. The insights gained from this study may guide organizations in developing better stress management practices and support programs to help employees thrive at work.
