beyond the call of duty because they want to reciprocate their positive experiences. Organ suggested that the empirically supported relationship between job satisfaction and organizational citizenship behaviours could be described as a reflecting relationship between perceptions of fairness and organizational citizenship behaviours. On the other hand, he also suggested that the cognitive component of job satisfaction appears to be related to orgaizational citizenship behaviours probably reflects the influence of perceptions. However, some studies argued there are no association between job satisfaction and organizational citizenship behaviours, which were considered to be related to other variables, such as transformational leadership behaviours (Podsakoff et al., 1990) and personality (Organ and Lingl, 1995). Other studies show that there is a positive relationship between job satisfaction and organizational citizenship behaviours (e.g. Chiu and Chen, 2005; Foote and Tang, 2008). Researchers suggested that job satisfaction could be a mediating variable between organizational citizenship behaviour and other variables, such as job characteristics and team commitment (Chiu and Chen, 2005; Foote and Tang, 2008). Studies show that both job satisfaction and organizational citizenship behaviour are associated to organizational outcomes significantly (Koys, 2001). Job satisfaction and organizational citizenship behaviour could thus be important variables for both employees and organizations. Methodological differences Methodological differences could explain differences between studies. Most of the earlier studies were based on samples from America and Australia, and almost all participants were employees in industrial companies. There is little focus on people with a higher education level, for example academics. The relation of job satisfaction and organizational citizenship behaviour could be different among academics, because of the high education level and features of academic work. The purpose of the study was to investigate and get a better understanding of the relationship between organizational citizenship behaviour and job satisfaction. In order to guide the investigation, the following specific questions were formulated: 1.What is the relationship between organizational citizenship behaviour and job satisfaction? 2.Are age, gender and length of service related to job satisfaction and organizational citizenship behaviours? The hypotheses of this study are: H0: There is no significant correlation between organizational citizenship behaviours and job satisfacton. H1: There is a significant correlation between organizational citizenship behaviours and job satisfaction. Methods Survey questionnaires were administered to staff of Department of Human Sciences in Loughborough University. Both academic staff and support staff were invited in this study. Participants were invited to participate in this study by e-mail. The e-mail outlined the survey details, such as the research proposal and the type of questionnaires.
