I think the most telling experience I ever had, was once, I was put on a PIP because I had a period where my sleep was extremely unhinged and uncontrollable, and no matter how deliberate I was in my sleep hygiene and avoiding stimulant and adjacent intake, I would sometimes be unable to get to sleep or stay awake, and this caused significant heartburn at my employer, who had fairly rigid in-office time requirements on high, but adored my work.

On my first meeting with someone in HR about it, they exclaimed in surprise "Wow, they really want to keep you. Usually when I'm talking to someone, it's because their manager wants them gone."

(I was not, ultimately, let go at the end of that process.)
