I'm not terribly well-informed about ENDA, but on many levels transgendered people are winning their rights. E.g. a friend of mine who works for a major TV network was able to get part of her surge paid for through her insurance company. AND the rest she was able to write off on her taxes as necessary surgery not covered by insurance.
After her operation her co-workers gave her party, took up a colection and gave her presents. There was also a booklet that went the rounds on how to deal with the transition. I thought it was all very properly done.
Of course the bigger the corporation, the bigger the potential lawsuit. But no-one made the co-workers throw a party.
