Illinois Resignation Law: Final Paycheck, PTO Payout, Non-Compete

Illinois is at-will but has one of the more employee-protective wage-payment regimes in the country. The Illinois Wage Payment and Collection Act (820 ILCS 115) treats accrued vacation as earned wages, gives strong enforcement remedies for late payment, and the 2022 Illinois Freedom to Work Act amendments restrict non-compete enforceability against most workers.

Final paycheck: 820 ILCS 115/5

Section 5 of the Illinois Wage Payment and Collection Act (820 ILCS 115/5) requires that all final compensation be paid in full at the time of separation if possible, but in no event later than the next regularly scheduled payday for the period during which separation occurred.

Late payment incurs a 5% per month underpayment penalty and 1% per month damages, plus attorney's fees and costs in a successful private action. Illinois Department of Labor can also pursue administrative penalties. Wage claims must be filed with IDOL within 1 year for amounts under $3,000 or with private litigation under longer common-law limitation periods.

PTO payout: vacation is wages

Section 5 of the Wage Payment and Collection Act explicitly includes accrued vacation in "final compensation." Illinois courts (Fasten Group v Saiganesh, 2003 and earlier cases) confirm that earned vacation cannot be forfeited at separation. The 2024 Illinois Paid Leave for All Workers Act added a layered floor of paid leave for all Illinois workers, although the payout-at-separation rule for that statutory leave is policy-dependent.

Cap-on-accrual policies (capping at 1.5x or 2x annual entitlement) are permissible. Use-it-or-lose-it policies that zero out vacation at year-end are commonly held unenforceable in Illinois. Use-it-or-lose-it at separation specifically is not enforceable under section 5.

Non-compete: Illinois Freedom to Work Act

The Illinois Freedom to Work Act (820 ILCS 90) was substantially amended effective 1 January 2022 to restrict non-competes. Under the amended Act:

  • Non-competes are void as to employees earning $75,000 or less per year (indexed upward, $80,000 for 2027 under the statute).
  • Non-solicit clauses are void as to employees earning $45,000 or less per year (also indexed).
  • Above the threshold, non-competes must be supported by adequate consideration (the statute defines adequate consideration as 2+ years of continued employment after signing, or other sufficient professional or financial benefits).
  • Non-competes against COVID-related laid-off workers and against independent contractors paid below specified thresholds are void.

Employers must give 14 days to review a non-compete before signing and advise the employee in writing of the right to consult counsel. Failure to comply renders the clause unenforceable.

Unemployment after voluntary quit

Illinois Department of Employment Security (IDES) disqualifies most voluntary quits from unemployment benefits, with a well-developed body of good-cause caselaw. Good cause attributable to the employer (substantial reduction in pay, change in duties, hostile workplace, unsafe conditions, employer breach of agreement) is the most reliable basis. Personal medical reasons with documentation can qualify. The IDES Adjudication Manual gives a usable list of examples.

Practical Illinois exit checklist

  • Final paycheck (including accrued vacation) is due on the next regular payday after separation under 820 ILCS 115/5.
  • Confirm payout of all earned vacation. Use-it-or-lose-it at separation is unenforceable.
  • Check your salary against the Freedom to Work Act thresholds. If you earn $75,000 or less, your non-compete is void by statute.
  • File any wage claim within 1 year for amounts under $3,000 via IDOL, or pursue private litigation for larger amounts.
