If you're allowed to get out! There are some vicious managers out there. The worst among them will force a PIP if they so much as think you might be hoping ship.
Luckily, in my time here, it has seemed like managers with this egregious behavior tend to get forced out of the company. However, they do insane amounts of psychological damage while they're here. Some teams have faced real tyrants :(
I had a friend who had exactly this happen, they wanted to switch teams and suddenly they had a PIP( that they were not even told about but which blocked the process ). She had to get the manager on the other team to investigate and once he started digging he found a completely empty draft PIP in place of a actual one. When he brought that up it disappeared the next day without a response from the original manager :////
