For me, it should've been 40 hours, but thanks to insanely ignorant management when I was working at McDonald's, it was more like 45 hours for me.

I said to them, "Get another patsy to do the overtime. I gotta go home and feed my dog." My manager then said, "F--- your dog. Get back to work." It took all my restraint not to pull my clip-on tie off and beat his ass down. (Everyone working at that McDonald's had to wear a tie.)
