Here's some hard (but free) advice from somebody who has been there and I hope you follow it:
Look.
What's happening to you is you're being managed out. It happened to me, it (might) be happening to you, and it's happened to countless other people at Target. It's just how they fire.
While sometimes a bad performance review is needed if you're not meeting management's expectations, it should feel somewhat obvious to you what the pain points are.
However, If you're blindsided after years of stellar performance, and the review you're getting seems excessively nitpicky or irrational, then what's happening to you is strategic and is not actually a reflection on your day-to-day performance, but instead, is a legal strategy to remove you from your employment. It's also miserable and demeaning to endure should you endure it. It's not designed to be fair, it's designed to get you to quit.
Take this as a sign that it's time to look for external employment, and get the jump early. Don't wait. It's pointless, fruitless, and doesn't solve anything. Think of it like staying in a bad relationship for too long hoping it will fix itself. Yeah, 1 out of 50 times it might, is it worth the grief? No. Life is to be lived. Move on.
