摘要:This paper is aimed at determining the effect of stress on job performance of employees. It is based on empirical research conducted on 133 employees of private sector-s Universities in Karachi that are providing education in the disciplines of Business Administration, Engineering, Medicine, Textile and Fashion. Pertinent data was collected through questionnaires based on close-ended questions. Multiple Linear Regression technique was used to test the hypothesis. The results obtained from the data revealed that workload and role conflict, and inadequate monitory reward are the prime reasons of causing stress in employees, and this stress reduces their efficiency. Thus it was recommended that employer should minimize stress by lowering the work load, abate the role conflict, pay adequate salary and provide training and counseling to employees in order to improve their job performance and job satisfaction.
