Heard about this statistic today (I follow a transgender twitter account that feeds all sorts of TG related news). Apparently, out of 50 states there are only 12 that protect transgender rights (mine included). That's right, 38 states can fire you if they don't like transgender, and they don't need a good reason, and you can't sue them for it:
"Wisconsin was the first state to ban employment discrimination based on sexual orientation, in 1982, while Minnesota was the first state to ban employment discrimination based on both sexual orientation and gender identity when it passed the Human Rights Act in 1993. Currently, 12 states and the District of Columbia have policies that protect against both sexual orientation and gender identity discrimination in employment: California, Colorado, Iowa, Illinois, Maine, Minnesota,New Jersey, New Mexico, Oregon, Rhode Island, Vermont, and Washington in the public and private sector. An additional nine states -- Connecticut, Delaware, Hawaii, Maryland,Massachusetts, Nevada, New Hampshire, New York, and Wisconsin -- have state laws that protect against discrimination based on sexual orientation only."
