I was put on PIP this year. I came to this site and talked about my experience. I received many, many kind words and suggestions from anonymous current/former coworkers here. Thank you all.
The past three months were quite difficult and tiring for me both physically and mentally. I lost countless hours of sleep and quite a few pounds, and skipped many activities I used to do with my kids... But now, I finally have the start date confirmed for a job I like --- a growing business, well known work life balance, 30+% increase in compensation, work from anywhere, and a 90+% approval rate of CEO on Glassdoor... So, It's time for me to leave XOM.
To anyone who might be in a similar situation: you do not deserve being treated that way. Don't be afraid of stepping out of the comfort zone and you will find something much, much better...
