© Cambridge University Press 2008 and Cambridge University Press, 2010. We are pleased to introduce Peter Cappelli’s Employment Relationships: New Models of White-Collar Work, as part of the Cambridge Companions to Management series. The series is intended to advance knowledge in the fields of management by presenting the latest scholarship and research on topics of growing importance. Bridging the gap between journal articles and student textbooks, the volumes offer in-depth treatment of selected management topics, exploring the current knowledge base and identifying future opportunities for research. Each topic covered in the series is one with great future promise, and one that also has developed a sufficient body of research to allow informed reviews and debate. Management scholarship is increasingly international in scope. No longer can scholars read only the work conducted in their own countries, or talk only to their near neighbors; creative and innovative work in management is now being conducted throughout the world. Each volume is organized by one of our most prominent scholars, who brings researchers from several countries together to provide cross-national perspectives and debate. Through this series we hope to introduce readers to scholarship in their field they may not yet know, and open scholarship debate to a wider set of perspectives. We feel fortunate to be working with Cambridge University Press. Their rigorous independent scholarly reviews and board approval process helps ensure that only the highest-quality scholarship is published. We feel confident that scholars will find these books useful to their own research programs, as well as useful in their doctoral courses.
