Earlier quoted context omitted.
Employability isn't the only factor, there's insurance, health, debt, rising cost of living, visa status, and so on that can make it such that, while you can _technically_ leave at any time, it may be disastrous to do so. Which has knock-on effects like "people with disabilities are pressured to not speak out on social media for fear of losing the job that is covering life-saving treatments" without better protection…
All of that stuff is irrelevant, you get a new job and all of that stays the same. You're just flailing for social justice buzz words now. As for "speaking out" on social media, that's not really a loss, it's useless. Talk to a lawyer, if you have a case, they'll take it for free. It's funny that slacktivism is so normalized that people think it's the right thing to do when they are trying to help themselves.
I'm glad life is so simple for you that you can just get free lawyers and new jobs whenever anything goes wrong, but others can't and they're concerns and fears that people deal with every day.
