This study tested an extended model of job satisfaction and life satisfaction, based on revised model of Life Satisfaction propounded by Daily and Near (2000). Results of regression analysis and path analysis of 379 full time Nigerian University staff, representing a national probability sample, indicated that relationship stress mediated the relationship between non-work satisfaction and life satisfaction, but that time conflict did not mediate this relationship. Job satisfaction had no direct effect on life satisfaction in this sample, and its indirect effect was mediated by non-work satisfaction.
