Hmm, all of my friends in nontechnical 9-5 jobs (factories, bank tellers, car mechanics) are able to have a couple paid hours leave with a doctor's note or signed appointment slip. Except for one who's a restaurant shift manager. I'd imagine this is more the case with smaller companies. In Tennessee, US.

Works for serious illneses, not much for anything else. You won't get extra time off (which doesn't cut into your paid leave) for dealings with your bank, barberer, vet, HOA, etc.
