That would be called vacation time vs sick time in my org, but there are definitely differences in when/how they’re used.
Sick time is like, “I don’t feel good today, I’m just not working today.”
Vacation time is like, “I’m feeling pretty good today, I’d like to take a feel-good day. But I better schedule schedule it a couple weeks out, check with my manager, make sure there are no deadlines coming up, make sure someone else can cover for me,” and so on.
This makes my bones hurt
