I’m not just saying this flippantly, as I can garner enough info from our past interactions to give specific-enough advice. You should join the public sector union. I know past and present members closely. I have a trans friend who got their help getting a manager who wouldn’t use her correct pronouns reprimanded by HR. My mum was also a member for over a decade.
I completely agree with where you’re at, and I’m really sorry that you’re living with this fear. I do believe though that a strong public sector union, with queer members in its ranks, would be capable of fighting the government on it. The construction union where I’m at showed up in force to protect trans folks from the alt-right at a TDOV rally.
