Advances in career theory and research: a critical review and agenda for future exploration.

In this review the authors critically examine the nature of contemporary careers and the direction in which careers research has developed over the past decade. Specifically, career concepts that emerged in the 1990s, including the protean and boundaryless career frameworks, as well as the next generation of career concepts, including integrative frameworks, hybrid careers, and the kaleidoscope career model, are discussed. The authors examine conceptualizations and measures of these models as well as related research. This review aims to improve our understanding of careers in today’s dynamic work environment, provide a comprehensive discussion of current discourse, and offer major directions for future research.
