So, did you stay long enough to accumulate FU money and then quit?

Because that's a bit easier than quitting or turning down a job when you need the income.

Since you say you're still working and have people to support I am guessing it was more the latter, but maybe the "very high paying job" gave you the runway needed to make that choice? I quit a high paying software job under different circumstances. The company wasn't doing anything unethical (that I know of) but I was just sick of how they managed people and projects. It had reached the point where I sat in my car for 15 minutes (or longer) every morning just trying to summon the willpower to get out and walk into the office. So I finally just quit. But it was easier as I had stashed away enough money to give me time to find a new job without having to jump on the first offer. I ended up freelancing a bit to extend the runway even longer.

I don't have FU money but I'm financially in a good spot, so definitely privileged compared to someone who would be out on the street with a few missed paychecks.

Congrats on getting out of a toxic situation btw, that's hard to do too if you're getting paid well. In a way I was similar, every morning started to be a real struggle for me.
