Laid off in Illinois: final pay, and what severance does not cover

A reduction in force is still a separation, and severance is not a substitute for wages already earned. In Illinois, a layoff follows the same rule as a discharge: pay at separation if possible, otherwise by the next regularly scheduled payday.

If you were offered severance in exchange for a release, the release covers claims — it does not convert earned wages into a favour, and it does not move the statutory deadline.

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.
Small claims limit
$10,000 for an individual

What to put in the file before you write anything

  1. The layoff notice or WARN letter, which usually states the separation date the employer will rely on.
  2. The severance agreement, read for two things: what it says about final wages, and whether it asks you to release the wage claim itself.
  3. Your accrual balance for PTO, and the employer policy that governs forfeiture in Illinois.
  4. Any commission or bonus plan document, because the payment date in the plan is what an employer will point to.

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 accepting severance waive my final paycheck in Illinois?

No. Severance is consideration for a release of claims; earned wages are already owed. A release that purports to cover unpaid wages is a separate question, and one worth reading carefully before signing.

Is my layoff deadline different from a firing in Illinois?

A layoff follows the same rule as a discharge: pay at separation if possible, otherwise by the next regularly scheduled payday.
