That sounds awful. Try to be aware so as to not bring any bad adaptations to your new job.

An old colleague shared a quote: "dysfunctional behaviors are functional in dysfunctional environments".

I've had to change up my style when I've moved to better (less political/dysfunctional) teams. I've also worked with some that never changed their mindset after being on a bad team: they then propagate that same broken behavior at their new workplace.

Best of luck in finding something better, it's out there.
