The elves, I think? Like that is my immediate conclusion. It is physical labor and craftsmanship, but they get to work as a team. They do work under a tight deadline, but ultimately Santa's is even tighter than that. And really, all of the pressure falls onto Santa because he's in charge and overseeing everything. But then we could also consider the wages and living conditions of the elves. Their standard of living, you know? Do you think they're slave labor?
