(CNN) - The suits allege that McDonald's has forced employees to work off the clock, not paid them overtime and struck hours off their time cards.
The suits were announced in a conference call led by the workers' lawyers and organizers of the union-backed campaign to raise fast food wages across the country.
Workers in California claim that McDonald's and its franchisees did not pay them for all of the hours they worked, and did not give them timely breaks.
The employees in Michigan allege that they would start getting paid only when customers walked into the restaurants, even if they showed up to work hours earlier.
New York McDonald's workers, who filed their case in federal court, claim the fast food chain did not reimburse them for the cost of cleaning uniforms. They say it drives some workers' real wages below the minimum wage, which is a violation of federal labor law.
These claims violate the federal Federal Labor Standards Act (FLSA), which sets minimum wage, overtime pay, record-keeping and other standards for workers across the country.
But wage theft at fast food chains has been an long standing issue. Last year, the New York State attorney general said he was investigating if fast food restaurant owners cheated their workers out of wages.
McDonald's said in a statement that it is currently reviewing the allegations in the lawsuits.
