Non-Disclosure Agreements in Illinois
Illinois enforces NDAs under general contract law and the Illinois Trade Secrets Act, which protects confidential business information from misappropriation. Courts require confidentiality restrictions to be reasonable in scope and duration.
Illinois' Freedom to Work Act restricts non-compete and certain confidentiality-adjacent restrictive covenants for lower-wage employees, so employers should ensure NDA-adjacent restrictions comply with these employee protections.
