In today's world, stress has become a global phenomenon, manifested in different forms in every workplace worldwide. For this study, role stress and its influence on job performance in selected banks in the Sunyani Municipality was assessed. A descriptive survey was conducted to identify the factors responsible for role stress in banks, effects of role-related stress on job performance, and stress coping strategies employed by bank employees in Sunyani municipality. Both secondary and primary data was used to gather information for the study. Questionnaire was used to collect data from 140 workers of five selected banks. The study revealed that workload, long working hours, reporting early to work, and lack of regular stress management practices were identified as the major factors contributing to role stress to the bank workers as affirmed by majority of the respondents. Again, the study found that there is a negative impact of role stress on job performance. Those workers who had high level of job stress exhibited low job performance. The study observed that management of the bank did not have established measures of managing stress among workers as affirmed by majority (85%) of the respondents. The study recommends that since the role-related stress from long working hours and workload were high among workers; the management of banks should pay attention to solving the issues of inadequate resources and equipment’s in order to prevent stress among staff and also improve upon performance.
