Current and former employees of the Detroit MGM Grand Casino are suing the casino for unfair labor practices.
What could be up to 200 employees claim the casino refused to pay floor supervisors for overtime.
The Fair Labor Standards Act says certain employees who work more than 40 hours a week are entitled to overtime pay.
But the complaint claims the casino hasn't done that.
Megan Bonanni is a lawyer for the employees. She says what the floor supervisors are asking for is only fair.
