On Monday, complaints were filed with the Occupational Safety and Health Administration detailing burns that McDonald's employees received while working. Nineteen employees filed complaints that stated the workers received burns from "popping grease". This series of complaints is part of a campaign by the Service Employees International Union to raise workers' minimum wage to $15 an hour and improve working conditions.
