Stop in for a cup of coffee

I should have took a day, but supposed to give 2 weeks notice and was just getting back from covid. They were supposed to pay out my remaining days for when I was off, but didn’t. So still have a few available….
I’m sure my supervisor would give me the day if I called right now, but he has no control on the payout. New guy in HR would likely screw me out of OT pay and I would end up working Saturday for straight time
