On the smaller front (TG) this is but further evidence we have a long way to go. But in the big picture, as Kat correctly pointed out, is employers are favored in discrimination cases and unless you have all your I's dotted and T's crossed, there's little chance of real fairness. The little guy loses.
This is why we can't just go online and bitch or complain. We have to get out there and make noise. Harvey Milk was quoted as saying, "If we all come out, we will win." To me, that means if everyone came out and their family and friends backed them, discrimination would end. The biggest problem the LGBT community faces is their own shame and fear. And it's worse for the T part of that.
I know this won't happen in what time I have left here but if we keep hiding and buying into the shame, it will take generations to see real change.
I'll do my part while I'm here but it's the youth who will make the most difference. In the meantime, anyone who plans on coming out at work, do your homework and document EVERYTHING! No matter what the laws say, it's the people who interpret them who will decide your fate.
