Field survey was conducted using job satisfaction survey (JSS) questionnaire having closed-ended questions. Multistage sampling was conducted using a combination of cluster sampling, stratified sampling and random sampling techniques. Power and Precision software was used to determine the sample size. JSS questionnaires were administered amongst 225 electrical and mechanical engineers from five public sector organizations. 158 usable questionnaires were received and data were analyzed in SPSS. Statistical analyses showed existence of an open mouth U-shaped relationship between LOS/age and job satisfaction. It was found that age moderates relationship between LOS and job satisfaction. Non-responsiveness of senior engineers led to one of the limitations of this study. Results of this study can be used for policy-making decisions.
