The concept of organizational commitment has received attention particularly in the field of industrial and organizational psychology (Cohen, 2003). It is a feeling of identification with organization’s values, contribution in the interest of the organization, and loyalty, expressed by employees (Steers, 1977). Organizational commitment is regarded as a dynamic construct comprising affective, continuance and normative commitment (Malik, Wahab and Naheem, 2010; Meyer and Allen, 1991). Commitment is also described as the psychological connection that binds employees to their employing organization. The concept of ‘investments’ defines membership and commitment is perceived as a force directing individual behaviour (Kiesler, 1971; Becker, 1960)
