Several studies showed that the empowerment is pathway to organization citizenship behaviour (OCB) among teachers. Therefore this study focuses on investigating the relationship of psychological empowerment, demographic characteristics and organizational citizenship behaviour Participants of the survey were both from public and private sector universities of Punjab. Data was collected using the self-administered questionnaire. 213 questionnaires were distributed among the different 18 universities in Pakistan. We received 194 questionnaires from our respondents but only 180 was accurately filled and used for further analysis. Thus the response rate is 85%. To determine relation between empowerment and OCB regression analysis was used. ANOVA analysis and independent sample t-test was used to examine the influence of demographic characteristics on OCB. Our findings show that psychological empowerment is significantly and strongly related to OCB. Furthermore, demographics are also found to be important to promote the OCB in university teachers, whereas tenure of the job is found to be significant predictor of employee empowerment.
