At Houston-based Metro Clean Commercial Building Services, some janitorial employees worked an average of 65 hours per week but were paid at their regular hourly wage, rather than receiving overtime pay. The company was also in violation of minimum wage laws, and in 2013, it agreed to pay $273,000 in back wages to 266 of its janitors.
