Illinois Statutes Chapter 820. Employment § 192/25. Retaliation

§ 25. Retaliation. It is unlawful for any employer to threaten to take or to take any adverse action against an employee because the employee (1) exercises rights or attempts to exercise rights under this Act, (2) opposes practices which the employee believes to be in violation of this Act, or (3) supports the exercise of rights of another under this Act. It is unlawful for any employer to consider the use of paid leave by an employee as a negative factor in any employment action that involves evaluating, promoting, disciplining, or counting paid leave under a no-fault attendance policy. Such retaliation shall subject an employer to civil penalties pursuant to this Act.

An employee who has been unlawfully retaliated against shall also be entitled to recover through a claim filed with the Department, all legal and equitable relief as may be appropriate.
