The study examines the effect of job involvement and participation on 'on-the-job' factors and 'off-the-job' factors of job satisfaction in different groups. Data were collected from a sample of 145 officers and 135 clerical personnel of a large banking organisation in west zone. The results tend to support previous research findings regarding the moderating effects of job involvement and participation on 'on-the-job' factors and 'off-the-job' factors of job satisfaction in different groups. In fact, significant interactions, between job involvement and participation, and job level and participation are obtained. The relationship between 'on-the-job` and 'off-the-job' factors are also discussed.
