Illinois Code § 35

§ 35.

Refusal to pay wages or final compensation; retaliatory discharge or discrimination. (a) Any employer who has been demanded by the Director of Labor or ordered by the court to pay wages due an employee and who fails to do so within 15 days after such demand or the order is entered shall be liable to pay a penalty of 1% per calendar day to the employee for each day of delay in paying such wages to the employee, up to an amount equal to twice the sum of unpaid wages due the employee. (b) Any employer, or any agent of an employer, who knowingly discharges or in any other manner knowingly discriminates against any employee because that employee has made a complaint to his or her employer, or to the Director or his or her authorized representative, that he or she or any employee of the employer has not been paid in accordance with the provisions of this Act, or because that employee has instituted or caused to be instituted any proceeding under or related to this Act or consulted counsel for such purposes, or because that employee has testified or is about to testify in an investigation or proceeding under this Act, or offers any evidence of any violation of this Act, shall be liable to the employee for such legal and equitable relief as may be appropriate to effectuate the purposes of this Section, the value of any lost benefits, backpay, and front pay as appropriate so long as the employee has made reasonable efforts to mitigate his or her damages and an additional equal amount as liquidated damages.
