In the United States, there are no federal laws prohibiting discrimination against employees based on their sexual orientation. However, Executive Order 13087, signed by President Bill Clinton, outlaws discrimination based on sexual orientation against federal government employees. If a small business owner owns his or her business in a state where there is a law against sexual orientation discrimination, the owner must abide to the law regardless of there not being a federal law. Twenty states and the District of Columbia have laws against this form of discrimination in the workplace. These states include California, Connecticut, Colorado, Hawaii, Illinois, Iowa, Maine, Maryland, Massachusetts, Minnesota, Nevada, New Hampshire, New Jersey, New Mexico, New York, Oregon, Rhode Island, Vermont, Washington, and Wisconsin. For example, California has laws in place to protect employees who may have been discriminated against based upon sexual orientation or perceived sexual orientation. California law prohibits discrimination against those "with traits not stereotypically associated with their gender", such as mannerisms, appearance, or speech. Sexual orientation discrimination comes up, for instance, when employers enforce a dress code, permit women to wear makeup but not men, or require men and women to only use restrooms designated for their particular sex regardless of whether they are transgender.
