Illinois Employment Laws That Affect Your Severance
Understanding these IL-specific protections is the first step to negotiating a better package.
21-Day Review for ALL Workers
Illinois's Workplace Transparency Act gives every worker — not just those 40+ — a 21-day review period and 7-day revocation right on severance agreements. This is rare nationally.
IL WARN Act (75 Employees)
State WARN kicks in at 75 employees with penalties up to $500/day. Mass layoffs of 25+ workers or 33% of workforce trigger notification requirements.
Mandatory Vacation Payout
Illinois requires payout of all accrued vacation at termination. "Use-it-or-lose-it" policies at separation are illegal.
Separate Consideration for Confidentiality
Employers must specify the exact dollar amount allocated to confidentiality clauses in severance. Vague confidentiality terms may be unenforceable.
Non-Compete Restrictions
Non-competes banned for employees earning under $75,000. Employers must provide 14 days' notice and advise you to consult counsel.
Pending: Mandatory Severance (Secure Jobs Act)
Proposed legislation would mandate severance for most terminations starting Jan. 2027 — 1 hour of severance per 12.5 hours worked.
WARN Act: Illinois vs. Federal
| IL WARN | Federal WARN | |
|---|---|---|
| Employer Threshold | 75 employees | 100 employees |
| Notice Required | 60 days | 60 days |
Key insight: Illinois WARN applies at 75 employees (vs. federal 100) and covers mass layoffs of just 25 workers or 33% of the workforce. Penalties include up to $500/day per violation plus 60 days of back pay.
Non-Compete Agreements in Illinois
Non-Competes Are Heavily Scrutinized
Illinois restricts non-competes for employees earning under $75,000/year. Employers must give 14 days' advance notice and advise you to consult an attorney. Courts apply a strict reasonableness test. If you prevail in a challenge, the employer pays your attorney fees.
