Effect of Economic Sector and Marital Status on Organisational Citizenship Behaviour among some Graduate Employees in Nigeria

The study investigated the effect of economic sector and marital status on organisational citizenship behaviour among some graduate employees in Nigeria, using the positivist explanatory cross-sectional (survey) research design, and a structured and validated questionnaire to systematically sample opinions of 1,532 male and female graduate employees across the various sectors of the nation's economy. Moreover, hypotheses were stated and tested using T-test of Independent Groups and Oneway Analysis of Variance. The results of the statistical analysis showed that graduate employees in the private economic sector expressed a significant higher level of organisational citizenship behaviour than their counterparts in the public economic sector (t= -2.122, df (1530) p <.05). The results also showed that there is a significant interaction effect of single, married, divorced and widow/widower on organisational citizenship behaviour F(3, 1528)= 3.33; P<.05. This is evident in the mean scores of participants across the four groups of marital status - single ( = 51.67); married ( = 52.69); divorced ( = 53.88) and widow/widower ( = 56.00). The study recommended that human resource managers should constantly facilitate seminar programmes and training schemes where employees could be more oriented on the importance of organisational citizenship behaviour.
