Illinois Employment Contract Review
Illinois regulates restrictive covenants with numbers. The Freedom to Work Act, 820 ILCS 90, sets earnings floors for non-competes and non-solicits, requires 14 days to review, and makes the employer advise you in writing to see a lawyer. Those floors step up on January 1, 2027. Illinois also requires pay scales in job postings and makes earned vacation part of the final paycheck.
Non-compete in Illinois
Limited, enforceable only in narrow cases
Are non-competes enforceable in Illinois?
Here is Illinois non-compete law in plain English, with the statute it rests on.
Void for employees earning at or below a salary threshold under the Freedom to Work Act. Above it, must be reasonable with proper notice.
Governing law: Illinois Freedom to Work Act, 820 ILCS 90.
Whatever the label in your contract, Illinois courts look at whether the restriction is reasonable in duration, geography, and scope. A nationwide, multi-year, whole-industry ban is far more likely to be narrowed or struck down than a narrow one.
Who owns what you invent in Illinois?
Illinois has a statute protecting inventions you create on your own time, with your own resources, unrelated to your employer's business, similar to California Labor Code §2870. A blanket assignment of "all inventions" that ignores this carve-out may be unenforceable as to your personal projects. Look for the statutory exclusion in your agreement.
Arbitration and class-action waivers in Illinois
Illinois has passed rules aimed at forced arbitration of employment claims, but the Federal Arbitration Act limits how far they reach, so many clauses remain enforceable. Check whether the arbitration clause is mutual and whether it waives your right to join a class action.
What are the Illinois thresholds and procedural rules?
For agreements signed after January 1, 2022, a non-compete is void unless your actual or expected annual earnings exceed $75,000, and a customer or employee non-solicit is void unless they exceed $45,000. Earnings include salary, bonuses, commissions and other taxable pay. On January 1, 2027 the floors rise to $80,000 and $47,500. The employer must advise you in writing to consult an attorney, give you at least 14 calendar days to review, and show adequate consideration.
If an employer sues to enforce a covenant and you win, 820 ILCS 90/25 lets you recover costs and reasonable attorney's fees.
What does Illinois require at separation and in postings?
Under the Wage Payment and Collection Act, 820 ILCS 115/5, final compensation, including earned vacation, is due no later than the next regularly scheduled payday. Since January 1, 2025, employers with 15 or more employees must include a pay scale and a general description of benefits in job postings under the Illinois Equal Pay Act.
Illinois also protects inventions you develop entirely on your own time without the employer's equipment, supplies, facilities or trade secrets, under the Employee Patent Act, 765 ILCS 1060, unless they relate to the employer's business or result from your work for it. The Illinois Attorney General can also act against employers that engage in a pattern of using unlawful covenants.

Illinois employment contract FAQ
Are non-competes enforceable in Illinois?
In Illinois, non-competes are enforceable only in limited circumstances under Illinois Freedom to Work Act, 820 ILCS 90. Void for employees earning at or below a salary threshold under the Freedom to Work Act. Above it, must be reasonable with proper notice.
Can my Illinois employer own inventions I make on my own time?
Illinois is one of a handful of states with a statute protecting inventions employees make on their own time, with their own resources, unrelated to the employer's business, similar to California Labor Code §2870. A blanket IP-assignment clause that ignores that carve-out may be unenforceable as to those personal inventions.
Do I have to sign a mandatory arbitration agreement in Illinois?
Illinois has passed rules aimed at forced arbitration of employment claims, but the Federal Arbitration Act limits how far state rules can reach, so most arbitration clauses are still enforceable. Read whether it is mutual and whether it waives class actions before you sign. Everywhere in the US, the federal Ending Forced Arbitration Act lets you take sexual harassment and sexual assault claims to court even if you signed one.
What makes a non-compete reasonable in Illinois?
Illinois does not set a presumptive maximum term, so reasonableness is assessed on the whole restriction rather than against a number: how long it runs, how much geography it covers, how broadly it defines the restricted activity, and whether it protects something the employer can genuinely claim an interest in. A restriction that is narrow on one of those and broad on the rest is still vulnerable.
What if I work in Illinois but my employer is in another state?
It matters, because Illinois's neighbours do not all treat non-competes the same way: Indiana (generally enforceable), Iowa (generally enforceable), Kentucky (generally enforceable), Missouri (generally enforceable), Wisconsin (generally enforceable). Which state's law applies turns on the governing-law and venue clauses in your contract and on where the work is actually performed, so those two clauses are worth reading closely before you sign.
If a Illinois non-compete is too broad, does it get narrowed or thrown out?
Courts may rewrite an overbroad restriction to something reasonable. That cuts against you: an employer has little to lose by drafting wide, because a court can pare the clause back rather than discard it. Negotiating the wording before signing matters more here than in states where an overbroad clause simply fails.
What else should I check in an Illinois employment contract?
Beyond the non-compete: how invention assignment is worded and whether it reaches work done on your own time; whether disputes go to arbitration and whether class actions are waived; whether notice periods are symmetrical between you and the employer; and how any equity vests, including what happens if you leave before a cliff.
What counts as adequate consideration for an Illinois non-compete?
The Freedom to Work Act codifies the rule that you must either keep working for the employer for at least two years after signing or receive other professional or financial benefits, such as a signing bonus or a raise. If neither is true, the covenant can fail for lack of consideration even when your pay clears the threshold.
Can my Illinois employer forfeit my unused vacation when I leave?
Not vacation you have already earned. The Wage Payment and Collection Act treats earned vacation as part of final compensation, so it must be paid by the next regularly scheduled payday. An employer can limit how much you accrue going forward, but it cannot take back what has already accrued.
