My resignation letters have always been fact-based and short. Nothing about reason or cause. Just: "I'm resigning. Date, last day, Thx, Bye."

On one job a while back, I resigned, but management had a PIP quota. So they put me back, pipped me, and gave me a severance check.

Like an idiot, I was like: "But I already quit."

Manager and HR on line are like: 🤦🏻‍♂️
