So I'm a manager. One of my team started feeling sick. He sent me an email saying he wanted to go home, and he'd work for another hour and a half to make it to the halfway mark, then apply half of his comp day (he'd worked on a weekend) to cover it.
Here's me, rolling my eyes:
I was going to send him an email that said, "I refuse your request for a comp day today" as the subject line, and inside say: "You're sick--that's a sick day!"
But I decided his sense of humor isn't robust enough for that, so I wrote a more sedate one saying, "No, if you feel unable to work for a physical reason, that's a sick day. Leave now. Feel better. Keep your comp day in the bank."
It wasn't "above and beyond" on my part by any means--and in a way, the "unwarranted loyalty" was his, to think that he needed to "pay for" his sick day. (I think he was still in the "freelancer paid by the hour" mindset, or something.)
When my mom died, I'd only been there about 3 months; my bosses said, "Take the time you need, we'll sort it out." I never did get asked to file time-off requests. I just went and came back. It was nice to not have to worry about that.
