I was at a work conference last week that was supposed to go M-F. It ended a day early and I drove home Friday during the day instead of Saturday. When I got back in the office today, my manager told me that I'd have to use one of my unpaid time-off days for this, since they didn't get any value out of my day. Is this a reasonable request or something I should push back on? For what it's worth I got the hotel I was staying at to refund one night, so it ended up saving them some money. I feel like this should at least count for something.
I'm in the US, and I'm paid a salary, not hourly. Unpaid time-off days are a limited benefit (we get ~5 per year). I could probably also use one of my PTO days, but those are very limited at 10 per year and I already have plans for them.
edit: It was a 6-hour drive, so it took most of a work day. I'm supposed to be reimbursed for gas+tolls+wear and tear on my personal car, but according to my coworkers it takes a lot of pulling teeth to get them to actually write the check. That's probably best left to another question though.
