The term job satisfaction was first coined by Hoppock in 1935. He defined it as the satisfactory feeling on both psychological and physical sides of the employees about the working conditions. It is the subjective responses of subordinates to work situations. Porter (1973) suggested that the extent of job satisfaction was the difference between the one who “really acquires” from work and the one who believed that he “should acquire” from work. A common view among managers is that satisfied employees were more productive than dissatisfied employees. Robbins (2001) suggested that job satisfaction was not only a general attitude toward one’s job, but also the differences between the amount of reward workers received and the amount they believe they should receive. In addition, he presented that the term of job satisfaction refers to an individual’s general attitude toward his or her job. A person with a high level of job satisfaction holds positive attitudes toward the job, while a person who is dissatisfied with his or her job holds negative attitudes about the job. As a psychological need and a factor to well being, job satisfaction is believed to have an environmental and genetic component (Arvey et al., 1989). There are several different variables, which are related to job satisfaction, such as cultural values, transformational leader behaviours and organizational commitment (Kirkman and Shapiro, 2001; Podsakoff et al., 1990; Feather and Rauter, 2004). There has increasing attention to the possible relationship between job satisfaction and organizational citizenship behaviour. Transformational leaders are those who ‘broaden and elevate the interests of their followers, generate awareness and commitment of individuals to the purpose and mission of the group, and … they enable subordinates to transcend their own self-interests for the betterment of the group’ (Seltzer et al., 1989). Transformational leadership is one of the groups of models describing leadership as an influencing social interaction or process. The process refers to one or a group of individuals which influence the behaviour of other people in an organizational setting for the purpose of achieving or accomplishing organizational objectives (Yukl, 2002). Transformational leadership behaviours raise the consciousness of followers about what is important, move followers to transcend the self-interest for the good of the organization, and raise their concerns for higher level needs on Maslow’s hierarchy (Bass, 1999). Studies have found that transformational leadership behaviours were positively associated with followers’ job satisfaction, and transformational leaders could increase followers’ job satisfaction motivated their followers (Podsakoff et al., 1990; Morrison et al., 1997) There is substantial support for the relationship between job satisfaction and organizational citizenship behaviors. Bateman and Organ (1983) found a significant relationship between general measures of job satisfaction and supervisory ratings of citizenship behavior. Schappe (1998) also suggested that cross-lagged patterns of the relationships between organizational citizenship behaviours and specific facets of job satisfaction revealed essentially the same results as overall satisfaction. Smith, Organ, and Near (1983) identified two separate dimensions of OCB: altruism and generalized compliance. Altruism refers to behaviours aimed at helping specific people directly and intentionally. Generalized compliance refers to a more impersonal type of conscientious behavior that does not provide immediate aid to a particular individual but is indirectly helpful to other people in the organization. Job satisfaction could be a major determinant of an employee’s organizational citizenship behavior. A satisfied employee seems more likely to talk positively about the organization, help others, and go beyond the normal expectations in their job. Moreover, satisfied employees mig>
