Illinois treats accrued unused vacation as earned wages under the Wage Payment and Collection Act (IWPCA § 5). The rule is similar to California's and Massachusetts's, but the remedies are different — Illinois imposes 5% per month statutory damages and attorney's fees on prevailing employees, capped, rather than the multipliers found in Massachusetts.
The rule, in plain terms
- Vacation is earned wages: Once accrued, vacation cannot be forfeited at termination. IWPCA § 5(a) requires payment of all "final compensation," which includes accrued vacation.
- Cap on accrual permitted: The employer may cap accrual (pause further accrual at a maximum balance), but cannot retroactively forfeit earned vacation.
- Use-it-or-lose-it (limited): Illinois generally does not enforce policies that retroactively erase already-accrued vacation. A clear policy that caps accrual prospectively is enforceable; a policy that wipes the balance at separation or year-end is not.
- Sick leave (Paid Leave for All Workers Act, effective 2024): Paid leave under the new state act generally does not require payout at termination unless the employer's policy promises payout. Local ordinances (Chicago, Cook County) have separate rules.
- Commissions: Earned commissions are wages owed under IWPCA. Plan language controls the "earned" definition.
- Statutory damages: IWPCA § 14 entitles a prevailing employee to 5% per month statutory damages, plus attorney's fees and costs.
Scripts to use
To enforce vacation payout at termination:
"Under the Illinois Wage Payment and Collection Act (820 ILCS 115/5), my accrued unused vacation is earned wages owed at termination. My balance is [N] hours at my final rate of pay. Please include this in my final paycheck."
When the employer claims forfeiture:
"Illinois law does not allow retroactive forfeiture of accrued vacation at termination. A policy capping prospective accrual is enforceable; a policy erasing earned vacation at separation is not. Please correct the final paycheck."
Statutory damages reminder:
"Failure to pay all final compensation triggers statutory damages of 5% per month under IWPCA § 14, plus attorney's fees. Please cure any underpayment by [date]."
What to document
- The vacation/PTO policy in effect at separation, including any caps
- Your accrued balance at the last day worked
- Your final rate of pay
- Pay stubs showing accrual through the last day
- The policy's history of changes during your tenure
When to escalate
If the employer underpays or refuses to pay accrued vacation:
- File a wage claim with the Illinois Department of Labor. Online filing, no filing fee, no attorney required.
- IDOL investigates and can order payment plus statutory penalties. Decisions are enforceable through the courts.
- For larger or systemic claims, IWPCA § 14 allows direct filing in court for actual damages, statutory damages, attorney's fees, and costs.
- Chicago workers should also check the Chicago Paid Sick Leave Ordinance and local ordinances on final pay.
Note: IWPCA's strong remedies — including mandatory attorney's fees on prevailing claims — make these cases attractive to plaintiffs' attorneys. A clear demand letter referencing § 14 often resolves vacation-payout disputes quickly.
