During the last fifteen years, researchers have shown increasing interest in the exchange relationship between the employee and employer. Until now, the literatures examining the employment relationships have tended to operate either from the employer or the employee perspectives and have typically approached the topic from a single discipline be it psychology, sociology, human resource management, organizational behavior, industrial relations, law or economics. Failure to consider multiple perspectives has created a fragmented understanding of the employment relationship. This volume incorporates social exchange, economics, industrial relations, legal, and justice theory perspectives. In addition, chapters have been written by authors that reflect the full international body of research on the employment relationship and provide information about legislation, governance, and cultural differences across nations. The conceptual and empirical foundations for understanding the employment relationship from these different theoretical perspectives facilitates the establishment of the convergent and discriminant validity of the psychological contract and the investments-contributions models of the employment relationship in relation to related exchange constructs such as perceived organizational support and leader-member exchange. The interdisciplinary and international nature of the employment relationship literature reviewed and integrated in this volume providesa richness that is rarely available in studies of the workplace, and many new and provocative ideas are presented in this volume. Bringing these perspectives together provides greater comprehensiveness, clarity, synthesis and understanding of the employment relationship. This volume is designed to promote the thinking of scholars in the employment relationship area. It will also have relevance to practitioners primarily through the implications of this multi-disciplinary perspective. The volume offers implications of a holistic, multi-disciplinary, international, conceptualization of the employment relationship for theory development, empirical research and measurement, and policy.
