(1)    The legislature finds that employee hour and overtime requirements that are uniform throughout the state is a matter of statewide concern and that the enactment of an ordinance by a city, village, town, or county regulating employee hours or overtime would be logically inconsistent with, would defeat the purpose of, and would go against the spirit of the employee hour and overtime requirements. Therefore, the employee hour and overtime requirements shall be construed as an enactment of statewide concern for the purpose of providing employee hour and overtime requirements that are uniform throughout the state.
