Lieberman cosponsored the Domestic Partners Benefits and Obligations act of 2009, which will provide the same benefits to same-sex domestic partners of federal employees as spouses currently have. In 1996, Lieberman cosponsored the Employment Non-Discrimination Act (ENDA), which would prohibit employment discrimination on the basis of sexual orientation. Lieberman has adopted a non-discriminatory policy in employment decisions, which include sexual orientation and gender.
