Lesbian, gay, bisexual, and transgender (LGBT) people constitute approximately five percent of the population, but workplace discrimination based on sexual orientation and gender identity remains troublingly commonplace. This article summarizes a large and growing body of social science research demonstrating the economic benefits of LGBT inclusion (and the costs of LGBT exclusion) in the workplace. It concludes with recommendations for (1) future research, stressing the need for more China-specific studies, which would inform policymaking and theoretical understanding of diversity and inclusion practices on business performance, (2) improving employer LGBT-inclusion policies, and (3) strengthening state protection of the equal employment rights of LGBT people.
