The Illinois Department of Labor is responsible for the enforcement of the Prevailing Wage Act, which requires contractors or subcontractors to pay not less than the prevailing wage to all laborers, workers, and mechanics engaged in the construction or demolition of public works. The Act also outlines the record-keeping requirements for contractors and subcontractors and requires that municipalities and other public bodies advise all contractors and subcontractors in writing of the Prevailing Wage Act when soliciting bids, awarding contracts, and issuing work orders.
