All states have laws that govern the hiring and employment of minors, in addition to federal child labor laws. Ensure you are familiar and in compliance with both federal and state law before you hire minors. If federal and state law overlaps, and the rules conflict on a specific point, the law that is most protective of the minor must be followed. These laws typically relate to age requirements, work hours, hazardous and prohibited work, posting requirements, and work permits.
State requirements specific to Wisconsin, Minnesota, Illinois, and Iowa are listed in the guide.
