Here’s a good indicator of how common wage theft really is: The Labor Department announced Tuesday that federal contractors had shorted 674 Senate cafeteria workers to the tune of $1 million. Two companies, Restaurant Associates and its subcontractor, Personnel Plus, violated the law by misclassifying workers into lower-paying positions and having them work off the clock, the agency said. Workers in the Senate were being illegally underpaid—not below the minimum wage, in this case, but below the levels set for federal workers in specific jobs.
