Feel for anyone stuck in that spot... Miaharris is right about the laws on paper, but the fear of getting crushed by lawyers is so real. It just makes the whole thing feel impossible to win.
Seriously, stronger laws don't always stop companies from making your life hell. I've seen it happen, so you gotta have every single thing in writing before you say a word. The legal fight after is brutal, even if you win in the end.
