I had a bad manager. As in verbally and physically aggressive. When I did the "correct" things: formally register my disability (autism) with my employer and file a complaint with HR... they gave me a syrupy story about how what I desribed was unacceptable and that the main investigator was on PTO, but to please reach out if I was retaliated against.
I reached out after said bad manager terminated me, and got a syrupy story about how maybe this week, but it's a busy meeting so the week after, they might bring up my concerns about retaliation.
I'm currently facing possible homelessness, because exercising your legal rights in these matters is time consuming even if you find a lawyer willing to help.
So dude... if you have these concerns, enough to ask for advice? Polish your CV and apply around before you have a CV gap.
