Diversity and its management has become a feature of modern and postmodern organizations. Different practices have spread around the globe focusing on the organizing and management of inclusion and exclusion of persons and identities based on different genders, sexual orientations, racial and ethnic backgrounds, ages, and (dis)abilities, as well as religious beliefs. Different diversity dimensions are identified and different explanations provided as to how and why these dimensions should be organized and ‘managed’ professionally. The discourses of equal opportunities, gender mainstreaming, and diversity management address these inclusion and exclusion processes each in their own ways while also intersecting. However, although increasingly recognized as important, the discourses of diversity are multifaceted and not without controversy. Furthermore, diversity management discourses and practices have the potential to reproduce both inclusion and exclusion. This book covers the rich and diverse field of diversity studies in organizations in one book. It presents the foundations of organizing and managing diversities, offers multidisciplinary, intersectional and critical analyses on key issues, and opens up fresh perspectives in order to advance the diversity debate. It also inspires new debates on diversity by encouraging scholars to broaden their research agendas and assists students and scholars to increase their understanding of the field and its current discussions. The authors are leading experts in the field from all over the world.
