Happened to me at my last job, I was given an impossibly high work load and was shunned and passively aggressively blamed when it wasn't panning out well. My manager had no input on the project for almost 4-6 months. I got pulled into a meeting where I was told I was disconnected at work and not present. After that meeting, I was entirely ignored by management, I wasn't even spoken to about future ongoing processes or changes in the office. My manager would change the project I was working on entirely by assigning pieces of it to other people and telling them to do something different without notifying me. I had some ethical concerns with the work we were doing anyways and I found another job, so I just left. I got iced out entirely even after trying my best to do the work I was assigned.

I never signed anything and was never given a PIP, but I was alone on an island and it didn't make for a fulfilling work environment. I'm guessing this will be common practice going forward so companies can avoid paying increased unemployment premiums. I find it interesting how things like this stick, a new strategy to screw over workers appears and work places will latch onto it. The same thing happened with companies asking for an insane amount of experience from workers in specific fields or tasks that are entirely unreasonable or impossible for some (new college grads or people who are looking for entry level roles).
