Yes, employees in the United States are protected from discrimination on sexual orientation under federal law. The landmark 2020 U.S. Supreme Court ruling in Bostock v. Clayton County affirmed that Title VII of the Civil Rights Act of 1964 prohibits such as discrimination, interpreting it as a subset of sex discrimination. This protection applies to employers with 15 or more employees, covering all aspects of employment hiring, firing, compensation, and promotions.

Additionally, state and local laws in jurisdictions like California and New York often provide even broader protections. Complaints can be filed with the Equal Employment Opportunity Commission (EEOC) or pursued through legal counsel.
