Psychological contract is about what the employees beliefs and what they receive or should receive because they perceive that their employer conveyed promises to provide those things’ in exchange for their contributions (Robinson, 1996, p. 575). sometime, organizations are not able to meet all the promises that conveyed to their employees so this lead to state of psychological contract breach (PCB), which has been found to have detrimental effects on employee attitudes and behaviours (Raja, Johns ; Ntalianis , 2004; Robins, Kraatz ; Rousseau, 1994; Tekleab, Takeuchi ; Taylor, 2005; Conway ; Briner, 2002; Parzefall ; Hakanen, 2010) Job satisfaction and effective commitment are the continuous goals of every organization so this study examines the effects of PCB on two critical organizational outcomes job satisfaction and affective commitment. Second, the moderating effects of two variables tenure and educational level are also tested.
