The central premise of this article is that organizations have social and economic interests in building policies and practices that support lesbian, gay, bisexual, and transgendered (LGBT) workers. This argument is based on empirical evidence that (a) LGBT workers continue to face discrimination at work from which they are not protected under federal law, and (b) discrimination has negative consequences for individual's mental and physical health, and on reasoning that (c) organizations share responsibility for the social good of the communities in which they operate. We offer practical suggestions for creating LGBT-supportive organizations and propose that industrial–organizational psychologists have an ethical obligation to support such efforts.
