In order to ascertain the specific causes of job stress, it is important to measure it accurately. The present paper made a modest attempt to develop a job stress inventory through factor-analytic approach. Two-hundred-and-seventy-six practicing managers from various companies took part in the study, answering the initial pool of 66 items of job stress of which finally 38 items were retained under five meaningful factors, such as distressful and agonizing job feelings, perceived neglect and fear of supervisors, fear of attrition, stressful work conditions, insecurity, etc. The psychometric properties of items and Cronbach’s Alpha Reliabilities calculated for subscale were quite satisfactory, ranging from .95 to .80. The Pearson’s correlation coefficient with subscales and intention to stay were found to be negative. The findings suggest that stressed managers are not satisfied and are inclined to leave the organization at the very first opportunity, resulting in their inability to contribute to organization’s potential and productivity.
