It doesn’t happen everywhere, but it can happen anywhere.

Usually it’s one or two people that set the tone and everyone else pretty much conforms, like you did. The next person to join your team, is probably going to go through the same thing.

I could make some guesses, but I don’t know how to fix it.

You’d probably be better off finding a new position and hoping it’s better, or until then, pray for major personnel changes.
