If you're based in the US you can take FMLA and pause the pip. Then max out your use of your pto.

That should give you a few weeks to look for another position and then when you get back (even if you have another gig) force them to actually follow through and fire you so they can't try to claim you left before the 1 year.

Depending on the company you could also ask about severance pay and some companies will pay you just to leave. It really all depends how old you are, sex, ethnicity and a few other things.

Thanks for the advice, I will do that, I have 12days of PTO left so that should be a good start.
