Walmart may end up paying as much as $85 million to its workers for unpaid wages, according to a settlement reached this week in federal court. After combining more than 30 lawsuits, U.S. District Judge Philip Pro approved a deal that requires the nation’s largest retail chain to reimburse employees for hourly wages that were denied either because of denied meal breaks or doctored timecards by supervisors. The settlement is part of an international $640 million deal that the company has reached with claimants all over the world.
