In this study, a psychological contract typology based on both content and exchange balance was developed. Content was defined along the transactional-relational dimension. Balance was assessed by comparing employees' perceptions on the number of employees' obligations relative to employer's obligations. Furthermore, the typology was related to type of employment contract (temporary versus permanent) as perhaps the most important antecedent of psychological contracts, and to various psychological consequences (job satisfaction, life satisfaction, organizational commitment, and psychological contract violation). Results were based on Belgian and German data (N=1267). Latent Class Analyses suggested four psychological contract types which are clearly distinct with regard to content terms and exchange balance: mutual high obligations, employee over-obligation, employee under-obligation and mutual low obligations. Temporary workers were more likely to hold psychological contracts with few employer obligations, such as the mutual low obligations and the employee over-obligation type. Finally, the mutual high obligations type was most beneficial in terms of psychological outcomes. Implications for future research are discussed.
