Diversity in the workplace has made significant progress in United States companies. Unfortunately, much of the apparent progress has been at the surface level of diversity (Hiller & Day, 2004), where readily visible characteristics identify people of varying genders, ages, ethnicity, and religions. What are needed are prescriptions, based on solid theory and research, that will allow the deeplevel diversity to transform well intentioned affirmative action programs from their old reliance on surfacelevel diversity to a new reliance on deeplevel diversity. It is our hope that this volume will stimulate the scholarly activity needed to make progress toward the above stated goal of making deeplevel diversity the benchmark of human progress in the workplace.
