The Employment Non-Discrimination Act (ENDA) is a proposed bill in the United States Congress that would prohibit discrimination against employees on the basis of sexual orientation or gender identity for civilian nonreligious employers with over 15 employees.
ENDA has been introduced in every Congress, except the 109th, since 1994, albeit without gender identity protections, but gained its best chance at passing after the Democratic Party broke twelve years of Republican Congressional rule in the 2006 midterm elections. However, some sponsors believed that even with a Democratic majority, ENDA did not have enough votes to pass the House of Representatives with transgender inclusion, and dropped it from the bill, which passed and subsequently died in the Senate. LGBT advocacy organizations were divided over support of the changed bill.
