The Director of the Department of Labor shall publish in the Illinois Register no less often than once each calendar quarter a list of contractors or subcontractors found to have disregarded their obligations to employees under this Act. The Department of Labor shall determine the contractors or subcontractors who, on 2 separate occasions within 5 years, have been determined to have violated the provisions of this Act. Upon such determination the Department shall notify the violating contractor or subcontractor. Such contractor or subcontractor shall then have 10 working days to request a hearing by the Department on the alleged violations. Failure to respond within the 10 working day period shall result in automatic and immediate placement and publication on the list. If the contractor or subcontractor requests a hearing within the 10 working day period, the Director shall set a hearing on the alleged violations. Such hearing shall take place no later than 45 calendar days after the receipt by the Department of Labor of the request for a hearing. The Department of Labor is empowered to promulgate, adopt, amend and rescind rules and regulations to govern the hearing procedure. No contract shall be awarded to a contractor or subcontractor appearing on the list, or to any firm, corporation, partnership or association in which such contractor or subcontractor has an interest until 4 years have elapsed from the date of publication of the list containing the name of such contractor or subcontractor.
A contractor or subcontractor convicted or found guilty under Section 5 or 6 of this Act shall be subject to an automatic and immediate debarment, thereafter prohibited from participating in any public works project for 4 years, with no right to a hearing.
