Closed DOL Wage & Hour Division cases (FLSA, FMLA, H-2B, MSPA, and related statutes). Backwages reflect amounts the agency assessed; civil penalty (CMP) is a separate fine levied on top, where the statute provides for one (FLSA / H-1B / H-2A / MSPA / FMLA / EPPA / FLSA Child Labor; other acts have no CMP column in DOL’s data).
