I've worked with similar people to this before and you're right, it completely disturbs the dynamic of a happy workforce when someone like this comes in. I'm sorry you have to put up with that.

I don't know if this could be an option, but perhaps if there is enough of a reason to take action, somebody could report it to a manager? For example if she's not abiding by covid rules, or she's being rude or snappy for no good reason, a manager could maybe have a word and get her to tone it down a bit? I completely get if this isn't something you'd want to do though.

Hopefully this PT settles down soon enough and doesn't cause too many problems.
