Sexuality, gender, gender identity, and gender expression are fluid constructs, and the ways in which identity development intersects with organizations and exists in society are complex. The book is comprised of a range of multi-disciplinary and globally inspired perspectives representing leading-edge scholarship by authors from over a dozen countries on a range of issues and contexts regarding LGBTQ identity and experience. It is intended for a wide readership: those who are in LGBTQ-related academic fields; those who want to broaden their coursework by offering supplemental readings that center the perspectives of LGBTQ identities; and those who want to acquire knowledge and education on the subject of LGBTQ identity. There are 36 chapters written by scholars in fields such as social work, law, queer studies, business, human resource management and development, entrepreneurship, criminal justice, economics, marketing, religion, architecture, sport, theater, psychology, human ecology, and adult education. The chapters can be read in sequence, and the book can also be used as a reference work for which educators, practitioners, and non-academics can identify and select particular chapters that inform areas of inquiry. This handbook is the recipient of the R. Wayne Pace HRD Book of the Year Award 2025.
