Currently, no federal law prohibits private employers from discriminating based on sexual orientation. That could change in the future, if Congress passed the Employment Nondiscrimination Act (ENDA), a bill that's been introduced in nearly every Congressional session for the last 15 years. Polls consistently show that a majority of voters support providing these job protections to gay, lesbian, and transgender employees and applicants.
In the meantime, however, many states prohibit sexual orientation discrimination at work, as do a number of cities and counties nationwide.
