On the work hours for students, I empathize with the need to focus on school, but there's some families that really need the money to survive and I lean toward giving them the right to do that, which I think is more important than their education (sadly).
Is there legislation that makes attendance compulsory for high school students?
I don't think there is anything in Atlasia. The reset put everything on US law, so generally it is, but it varies based on the state. Some states require students to stay until they're 18 and others allow them to leave earlier. I assume the reset included state law, but I actually have no idea on that.
