Things are absolutely not like this everywhere. I don't know where you got this idea that things can never be better than terrible, but it isn't true.

> My goal of doing bare minimum is to teach them a lesson

I mean, you do you, but to me this vindictive motive reads as super unprofessional and could backfire on your career, even outside of this company. It's one thing if you're trapped at this job because of circumstances outside of your control, but assuming you have the opportunity to look for something else, you owe yourself more than to intentionally stay in a toxic workplace just to get some kind of misguided revenge (?).

Move on. Your career is not a torpedo whose only remaining purpose is to detonate itself at a target that's done you wrong. Leave the toxicity behind and do something you'll feel good about.
