Part I of the Handbook dissects the theoretical reasons and shows how the study of workplace diversity follows different directions. Part II critiques quantitative and qualitative research methods within the field, while Part III investigates the parallels and distinctions between different workplace groups. Key issues are drawn together in an insightful introduction from the editors, and future directions for research are proposed in the conclusion. The book reviews issues concerning workplace diversity along several important dimensions (e.g., gender, race, ethnicity, weight, sexual orientation, disabilities, class), and it offers useful recommendations for how to conduct future research that will expand knowledge of the implications of diversity for individuals, marginalized groups, work organizations, and societies.
