This includes 2.4 million workers in the 10 most populous states.
“This report assesses the prevalence and magnitude of one form of wage theft—minimum wage violations (workers being paid at an effective hourly rate below the binding minimum wage)—in the 10 most populous U.S. states. We find that, in these states, 2.4 million workers lose $8 billion annually (an average of $3,300 per year for year-round workers) to minimum wage violations—nearly a quarter of their earned wages. This form of wage theft affects 17 percent of low-wage workers, with workers in all demographic categories being cheated out of pay.”
