We provide a review of psychological contract research, beginning with past conceptualizations and empirical evidence. We tailor this retrospective look by reviewing the antecedents and outcomes associated with psychological contract breach and discussing the dominant theoretical explanations for the breach-outcome relationship. This synthesis of past evidence provides the foundation for reviewing the present emerging and developing themes in psychological contract research. This discussion is organized around the expansion of resources exchanged and the antecedents of contract breach and outcomes, moving beyond reciprocity as an underpinning explanation. We highlight the practical implications of research to date on psychological contracts and end with directions for future research to include the need for greater attention given to ideological currency, employee health, polycontextual approaches, the role of psychological needs, and post-breach/violation.
