If it's any consolation, the day after I told my employer that i was transitioning I was fired and walked right out the door. I had dreams of transitioning on the job, getting surgery and living happily ever after, but that all turned out to be a pipe dream.
I had no choice, I had to start over. I was left with no other possibilities. I hadn't worked there very long for severance pay so I was pretty much in the cold for a while. Looking back, I have to think I had some pretty big kahunas because the day after I was fired I did my name change and said this is it.
You know going back to old employers turned out to be quite a blessing in disguise. I really really didn't want to do it, I was scared to death, but I did it. I had a really good reputation at other employers including the one who fired me, and I got a lot of tips, places that were hiring, etc. In the end, I had an old boss who surprised me utterly by helping to find me a job. If you would have asked me in a million years that he would have been helpful I would have said no. He was what women call a "sexist horn dog pig" but he was really nice to me and even greased the new employer with a solid endorsement. It was all I needed to get back in the front door and start a new job. At the end of the interview, they made me a job offer on the spot. I was so happy, I said yes. It was far less than I was worth, but that's the least wonderful part of the world of women, being underpaid.
