This third title in our "Understanding Organizational Change" series offers readers a selective, critical and synthetic historical review of the main literature and empirical research on change agency. In doing so it helps students to contextualise this complex subject area while providing an interdisciplinary review of the subject. The book takes a controversial approach designed to both heighten student criticality and challenge practitioners. The aim is that having read this book, readers will be able to evaluate independently the future prospects for effective change agent roles in organizations. A much-needed review of a fascinating area of organizational change.
