Not without additional compensation. The Michigan Workforce Opportunity Wage Act defines a workweek, overtime, and pay rates. Under the Act, a workweek is defined as 40 hours. If you’re asked or scheduled to work more than 40 hours a week, your employer must compensate you with the overtime pay rate of one and one-half times your standard rate.

Your employer can’t necessarily make you work overtime, but if you’re an at-will employee, you can be legally fired for refusing to work the extra hours.
