Consumer goods company Procter and Gamble has joined a coalition of businesses backing a bipartisan effort of end workplace discrimination based on sexuality and gender identity.

The company is backing the Emloyment Non-Discrimination Act (ENDA), and has joined other Fortune 500 companies, as well as small businesses and politicians both Democratic and Republican in doing so.

The US currently has very few states with anti-discrimination laws. Few states have a law which prohibits an employer from firing or refusing to hire someone because he or she is gay, lesbian, bisexual or transgender.

ENDA would change that by adding sexual orientation and gender identity to federal workplace discrimination protection, including race, religion, gender and disability.
