In the new world of work and organizations, creating and maintaining a positive identity is consequential and challenging for individuals, for groups and for organizations. New challenges for positive identity construction and maintenance require new theory. This edited volume uncovers new topics and new theoretical approaches to identity through the specific focus on positive identities of individuals, groups, organizations and communities. This volume aims to forge new ground in identity research and organizations through a compilation of new frame-breaking chapters on positive identity written by leading identity scholars. In chapters that build theoretical and empirical bridges between identity and growth, authenticity, relationships, hope, sustainability, leadership, resilience, cooperation, and community reputation and other important variables, the authors jumpstart an exciting domain of research on new ways that work organizations are sites of and contributors to identities
