Illinois’ 10-Year Statute of Limitations for Written Wage Contracts: How to Recover a Decade of Unpaid Wages

Could My Work Contract Protect Me If I Sue My Employer?
An Illinois worker who discovers years of possible underpayment could have more than one type of claim. A federal claim under the Fair Labor Standards Act (FLSA) generally has a two-year filing period, which could extend to three years when a violation is proven willful. Illinois law provides a separate 10-year filing period for claims brought under the Illinois Wage Payment and Collection Act (IWPCA). The IWPCA generally covers compensation owed under an employment contract or agreement, but that agreement does not necessarily have to be a formally signed contract. A written agreement could still help show what the employer promised to pay.
The Important Distinction
Under 735 ILCS 5/13-206, actions brought under the IWPCA generally have a 10-year filing period. A worker would still need to show that the employer owed the compensation under an employment contract or agreement and that the claim was filed before the applicable deadline. A signed contract could be helpful evidence, but its existence would not automatically prove that wages are owed.
Why the Filing Deadline Could Matter
A statute of limitations is the deadline for filing a lawsuit. When the same alleged pay practice continues for months or years, that deadline could determine how many pay periods may be included in the claim.
For example, consider an employee who was allegedly underpaid by $100 each week for eight years. Two years of underpayments would total about $10,400, while eight years would total about $41,600 before any additional damages or other relief. This example only shows how the filing period could affect the amount of wages being reviewed. It does not establish that a violation occurred or predict what a worker could recover.
Under 735 ILCS 5/13-206, an IWPCA claim generally has a 10-year filing period. The clock begins when the claim “accrues,” which generally means when the worker has the legal right to bring that claim. The same section also applies to certain written-contract claims.
A different five-year period under 735 ILCS 5/13-205 could apply to certain unwritten-contract claims brought outside the IWPCA. The applicable deadline could depend on the type of claim and when each alleged underpayment occurred.
Illinois and Federal Wage Claims
The Illinois Wage Payment and Collection Act (IWPCA) could apply when an employer does not pay compensation required by an employment contract or agreement. Depending on the circumstances, the disputed compensation could include regular wages, commissions, bonuses, earned vacation pay, final pay, or money withheld through an allegedly improper deduction. A worker who proves an IWPCA claim could also qualify for statutory damages, court costs, and attorney’s fees.
The FLSA uses a different set of rules. A federal minimum wage or overtime claim generally has a two-year filing period. That period could extend to three years when the worker proves that the violation was willful. The FLSA could also allow liquidated damages, which are an additional amount that could equal the unpaid minimum wages or overtime compensation.
When the facts support both claims, an Illinois worker could rely on the IWPCA and the FLSA in the same lawsuit. Bringing both claims would not automatically extend the federal filing period or allow the worker to collect twice for the same unpaid wages. Each claim would need to be considered under its own requirements.
What If I Don’t Have the Original Contract?
A signed employment contract or commission agreement could provide clear evidence of what an employer agreed to pay. However, in some cases, even offer letter, bonus plan, handbook, written pay policy, or other communication could also be relevant. The IWPCA refers to an employment “contract or agreement,” so the document being titled “employment contract” is not necessarily limited to a single formal document. A court could consider the employer’s written policies, communication between you and your workplace, and the way compensation was calculated and paid.
For example, pretend you’re a sales representative that has worked for an Illinois company for seven years under a signed commission plan. The plan listed the commission percentage and the sales that would qualify, but the worker alleges that the employer repeatedly excluded qualifying sales. Those facts could support an IWPCA claim and possibly a separate contract claim. The worker would not automatically recover seven years of commissions. The result could depend on the wording of the plan, later changes to the agreement, payment records, filing deadlines, and the employer’s defenses.
A written contract is not required for every wage claim. For example, an employee who alleges unpaid overtime based on the hours worked and the duties performed could have an FLSA claim without any employment agreement. That federal claim could be limited to two years, or possibly three years for a proven willful violation. The existence of a pay stub, offer letter, or other document would not automatically create an IWPCA or contract claim.
Pay Practices That Could Raise Questions
Possible wage claims are not limited to one type of pay. Questions could arise when an employer does not follow a written commission formula, does not pay a promised bonus, automatically deducts 30 minutes for meal periods when work was allegedly performed, or requires work before clocking in or after clocking out. A worker’s classification as exempt from overtime or as an independent contractor could also affect the analysis.
None of these situations would prove a violation by itself. An automatic meal deduction, for example, could be lawful when the employee receives a genuine, uninterrupted meal period and has a reasonable way to report a missed or interrupted break. The same deduction could raise wage concerns when the employer knew or should have known that the employee continued working.
What Relief Could Be Available?
The relief available could depend on which claim the worker proves. It could include unpaid compensation, interest, attorney’s fees, court costs, and additional damages created by statute. Under the FLSA, liquidated damages could equal the unpaid minimum wages or overtime compensation.
The same pay policy could affect several employees, which could lead to consideration of a collective or class case. Whether a case could proceed on behalf of a group would require a separate review of the facts and legal requirements. Any amount recovered could vary from worker to worker based on the applicable law, available records, defenses, and the court’s findings.
Records That Could Help Evaluate a Claim
Employment contracts, offer letters, commission or bonus plans, handbooks, pay policies, pay stubs, time records, schedules, and messages about compensation could help an attorney evaluate a potential claim. A written agreement should be reviewed together with any later changes and the records showing how the employer actually calculated and paid compensation.
A worker could also prepare a timeline showing when the possible underpayment began, how often it occurred, and when it was discovered. Different claims could have different deadlines, so the timing of a legal review could affect which pay periods remain available.
Illinois Could Provide More Time for Certain Claims
Illinois’ 10-year filing period for IWPCA claims could make a substantial difference in some wage disputes, but it does not give every worker a valid claim covering 10 years. One worker could have only a federal overtime claim, while another could have an IWPCA claim, a separate contract claim, or several related claims. The employment agreement, pay records, timing, and specific facts could determine which deadlines and remedies apply.
