A basic underlying assumption of the psychological contract is that both parties come to a mutual agreement about the expectations and obligations of a contract of employment. Recent research provides evidence of the potential for employees to develop unrealistic expectations from this contract and this has been described as a sense of entitlement. In this article, we outline two studies. In the first study, we test the internal structure and reliability of a scale we developed and named the Measure of Employee Entitlement. In the second study, we test the predictive validity of the Measure of Employee Entitlement against a measure of reciprocity. The development and validation of the Measure of Employee Entitlement extends our knowledge of sense of entitlement in the workplace and situates entitlement as a factor that may impact on the development of psychological contracts. This research provides a platform from which researchers and practitioners can continue to coherently and consistently investigate the phenomenon of employee entitlement.
