As organizations globalize, culturally based variation in the ways employees conceptualize their relationships with their employers increases in importance. In the competition for talent, organizations must understand employee preferences and expectations regarding their treatment by the firm. Recently, culture's influence on the psychological contract (individual perceptions of employer obligations) has been noted with regard to the extent that employees perceive their psychological contracts as relational or transactional. We provide results from a survey conducted in a multinational corporation (MNC) indicating that the cultural value of collectivist orientation likely has its effect on the psychological contract through beliefs about the nature of social exchange. Data were consistent with creditor exchange ideology (appropriateness of giving more than has been received) mediating the relationship between collectivist orientation and perceptions of a relational psychological contract. By examining this relationship empirically, we go beyond the demonstration of cultural effects to describe an intermediate mechanism through which culture operates. Exchange norms are likely to play a mediating role in a variety of cross-cultural relationships, and may be used by managers as a lever to improve relationships with employees, as opposed to engaging in attempts to change individual cultural orientation.
