For many Illinois business owners, protecting trade secrets and competitive advantages is a top priority. One of the most common ways to safeguard these interests is through a non-compete agreement. These contracts restrict an employee from joining a competitor or starting a similar business for a certain period after leaving your company.
However, recent changes in both Illinois state law and federal policy have significantly limited when and how employers can use non-competes. If your business operates in DuPage County, check with a Wheaton business law attorney before asking an employee to sign one.
What Does Illinois Law Say About Non-Compete Agreements?
Illinois does not prohibit non-compete agreements outright, but as of October 2025, the Illinois Freedom to Work Act (820 ILCS 90/) still places strict limitations on when they can be used.
