Unused PTO in Illinois: must it be paid out?

Illinois requires payout of earned, unused vacation only if the employer's written policy or contract provides for it; the policy is what a claim turns on.

The practical question is not whether your employer has a policy — most do — but whether that policy actually forfeits earned time, and whether it was communicated before you earned it.

Statute
820 ILCS 115/5 (Illinois Wage Payment and Collection Act); 115/14 (penalties)
If fired
Final compensation is due at the time of separation if possible; if it is not possible to calculate it then, it is due no later than the next regularly scheduled payday (820 ILCS 115/5).
If you resigned
Same rule on resignation: final compensation at separation if possible, otherwise by the next regularly scheduled payday.
Late-pay penalty
820 ILCS 115/14(a): damages of 5% of the underpayment per month it stays unpaid (2% per month where the underpayment is $200 or less), capped at 100%, plus a court-awarded attorney's fee and costs.
PTO
Illinois requires payout of earned, unused vacation only if the employer's written policy or contract provides for it; the policy is what a claim turns on.

What to put in the file before you write anything

  1. Your accrual balance on the last day of work, from the payroll system rather than from memory.
  2. The policy in force during your employment, with its effective date — a policy adopted after you accrued time is a weaker defence for the employer.
  3. Whether the policy says "use it or lose it", caps accrual, or is silent. Silence usually favours the employee.
  4. The payout rate: accrued hours are normally paid at your final rate of pay, not at an older, lower rate.

What the letter does that a phone call cannot

A demand letter fixes three things at once: the amount, the date each item was due, and the date the employer was on notice. Every forum that can help you — the Illinois Department of Labor — Wage Payment and Collection, a small claims judge — starts from those three facts. The letter is built from 820 ILCS 115/5 (Illinois Wage Payment and Collection Act); 115/14 (penalties) and your own figures, so the deadline it states is the one that applies to your separation, not a generic thirty days.

If the amount fits inside $10,000, small claims court is usually faster than an agency queue; if it does not, the agency route and a demand first is the cheaper path.

Questions

Does Illinois law require vacation payout?

Illinois requires payout of earned, unused vacation only if the employer's written policy or contract provides for it; the policy is what a claim turns on.

Can my employer retroactively cancel my PTO balance in Illinois?

A forfeiture has to come from a policy that applied while the time was being earned. A policy introduced at separation, or applied only to departing employees, is the weakest version of the argument and is worth challenging in writing.
