Length of hours per day for a 17yr old

Minors, ages 14 and 15, can work between 7:00 a.m. and 9:00 p.m. while 16- and 17-year-olds can be employed between 6:00 a.m. and 10:30 p.m. (11:30 p.m. on Friday or Saturday or when not regularly attending school) for up to 48 hours per week of school and work combined. "Michigan child labor laws require that minors cannot work more than five hours without a 30-minute break period," Finn said. "Adequate adult supervision is also required for the safety of working minors. Minors cannot work past sunset or 8:00 p.m., whichever is earlier, without adult supervision at a fixed location where cash transactions occur." This is MI state law on working under the age of 18.Hope it helps
