Increasing workplace diversity has given rise to growing intergroup challenges that persistently manifest in discrimination. An emerging science in psychology, sociology, and management has yielded useful evidence to be brought to bear on the important problem of discrimination, but most literature available focuses on social (rather than work) settings or legal (rather than interpersonal) issues, or focuses on the general phenomenon of diversity rather than the social problem of discrimination. Contributing authors address the unique experience of people from diverse perspectives (such as religious minorities, gay and lesbian workers, and those with disabilities) and the ways in which discrimination can be manifested and its consequences, and offer explanations for discrimination and strategies for its reduction.
