I spent some young teen years working in McD's and other short order gigs way back when (late 70's). Let's have a look.

>More than 3 hours per day and after 7 p.m. on school days when the law forbids work beyond that time.

Seven PM is the cutoff? Seems a bit early. Counting in at least 1-2 hours of homework time after school, that's barely enough to make it worth the parent's taxi. As to doing homework after work, screw that - after a few hours working Mickeys you wanna get a long shower and relax. Past 10 or 11 PM would be right out, but 7 is lame.

>Later than 9 p.m. on days between June 1 and Labor Day, when they may legally work until 9 p.m.

I was probably raised wrong as a child. When I work summer vacation is between me and my parents and I could get hours + shift differential, so much the better for me.

>More than 8 hours on a non-school day, and more than 18 hours a week during a regular school week.

I can go with half of this; working more than 8 hours almost anywhere should never be part of a game plan. But 18 hours max sounds a bit restrictive. I could get 8-12 hours of that on weekends alone.

I dunno. I'm some sort of ancient barbarian I guess, or maybe grade school is far more grueling than I remember.
