Can I sue for wrongful termination in Illinois?

Federal & State Law Editorial TeamLast reviewed: 2026-05-18

1. At-Will Default

Illinois follows at-will employment subject to robust exceptions.

2. Public Policy Exception

Kelsay v. Motorola, Inc., 384 N.E.2d 353 (Ill. 1978), recognized a retaliatory-discharge tort for firing an employee for filing a workers' comp claim. Palmateer v. International Harvester Co., 421 N.E.2d 876 (Ill. 1981), extended the tort to firings for reporting criminal activity. Public policy must be clearly mandated by constitution, statute, or judicial decision.

3. Implied Contract

Duldulao v. Saint Mary of Nazareth Hospital, 505 N.E.2d 314 (Ill. 1987), recognized handbook-based implied contracts when language is clear, disseminated, and accepted by continued employment.

4. Implied Covenant of Good Faith

Not recognized for at-will employment (Mitchell v. Jewel Food Stores, 568 N.E.2d 827 (Ill. 1990)).

5. Statutory Discrimination Claims

Illinois Human Rights Act (IHRA), 775 ILCS 5/, covers race, sex, age (40+), disability, sexual orientation, gender identity, marital status, arrest/conviction record (with limits), and more. Enforced by Illinois Department of Human Rights (IDHR); charge within 300 days. EEOC within 300 days.

6. Retaliation Statutes

Illinois Whistleblower Act, 740 ILCS 174/ — protects disclosures of illegal activity to government and refusals to participate. Workers' Comp Act § 4(h). One Day Rest in Seven Act retaliation.

7. WARN Act

Illinois WARN, 820 ILCS 65/ — 60 days' notice; 75+ full-time employees (lower threshold than federal 100).

8. Damages

Retaliatory discharge tort: back pay, compensatory, punitive (Kelsay). IHRA: back pay, front pay, compensatory, attorney's fees, no punitive. Whistleblower Act: back pay, reinstatement, attorney's fees.

9. Statute of Limitations

Retaliatory discharge tort: 5 years (735 ILCS 5/13-205); IHRA charge: 300 days; Whistleblower: 5 years; written contract: 10 years.
