I’ve seen this situation play out, where the PIP was termination with X days notice. Because the manager knew, and employee should have known, the manager didn’t really work with the employee or review their work because why bother, nothing will change (outside of something exceptional happening). Somewhat similar thing happened on the final review, but without pointing to hard data of the fact. The decision of course remained final, the manager got a light, informal water cooler “hey be more careful of optics” chat, and that was it. Notably when the former employee tried to go a competitor, former company killed that.
