I have PTO and time off from overtime which can temporarily go negative.and if it's negative at end of year the rest becomes unpaid time off. Due to special tax fuckery in my country, unpaid time off actually isn't objectively a thing, instead, my company pays tax based on my nominal salary and I have to pay them back with tax

To get out of this, I negotiated a rather special position where I'm registered for 6 hour days for a few months so that I can aggregate a bunch of overtime to be spent as extra unpaid time off that we aren't paying employment tax on for no reason when no work or payment is taking place.

This creates a rather funny loophole, in that my PTO days are worth 6 hours during these months but 8 hours for the rest of the year, whereas overtime and corresponding time off is measured in hours so it's always worth the same.

Naturally, like the strategic genius I am, I started recording all my absence in this period as PTO days without thinking because I wanted to see my time off on a nice universal counter. I realized about an hour ago that I'd been taking PTO at 75% efficiency.
