820 ILCS 115/11
It shall be the duty of the Department of Labor to inquire diligently for any violations of this Act, and to institute the actions for violations and penalties herein provided, at the request of the employee or on motion of the Director of Labor, and to enforce generally the provisions of this Act.
An employee may file a complaint with the Department alleging violations of the Act by submitting a signed, completed wage claim application on the form provided by the Department and by submitting copies of all supporting documentation. Complaints shall be filed within one year after the wages, final compensation, or wage supplements were due.
Wage claim applications shall be reviewed by the Department to determine whether there is cause and sufficient resources for investigation.
The Department shall have the following powers:
(d) In addition to the aforementioned powers, subject to appropriation, the Department may establish an administrative procedure to adjudicate claims and to issue final and binding administrative decisions on such claims subject to the Administrative Review Law. To establish such a procedure, the Director of Labor or her or his authorized representative may promulgate rules and regulations. The adoption, amendment or rescission of rules and regulations for such a procedure shall be in conformity with the requirements of the Illinois Administrative Procedure Act. If a final and binding administrative decision issued by the Department requires an employer or other party to pay wages, penalties, or other amounts in connection with a wage claim, and the employer or other party has neither:
(i) made the required payment within 35 days of the issuance of the final and binding administrative decision; nor (ii) timely filed a complaint seeking review of the final and binding administrative decision pursuant to the Administrative Review Law in a court of competent jurisdiction, the final and binding administrative decision is a debt due and owed to the State and may be collected using all remedies available under the law, including, but not limited to, those found in Article XII of the Code of Civil Procedure. The findings, decision, and order of the Department may be enforced in the same manner as any civil judgment entered by a court of competent jurisdiction. Nothing herein shall be construed to prevent any employee from making complaint or prosecuting his or her own claim for wages. Any employee aggrieved by a violation of this Act or any rule adopted under this Act may file suit in circuit court of Illinois, in the county where the alleged violation occurred or where any employee who is party to the action resides, without regard to exhaustion of any alternative administrative remedies provided in this Act. Actions may be brought by one or more employees for and on behalf of themselves and other employees similarly situated.
Nothing herein shall be construed to limit the authority of the State's Attorney of any county to prosecute actions for violation of this Act or to enforce the provisions thereof independently and without specific direction of the Department of Labor.
