Psychological contracts, an individual's system of beliefs regarding exchange arrangements, are key components in the construction and development of individual careers and the career systems of organizations and societies. In explicating careers and their management, multiple stakeholders are increasingly relevant to worker psychological contracts as individuals shoulder greater responsibility for their own careers and seek resources and ties with diverse career agents.
