The Illinois Supreme Court has completely changed the way the Courts are to look at non-competition agreements. The decision seems to favor the entity attempting to enforce the non-competition agreement. In the case of Reliable Fire Equipment Co. v. Arredondo, 2011 IL 111871 published on December 1, 2011, the court confirmed that an employer must demonstrate a “legitimate business interest” (LBI) to enforce an otherwise reasonable post termination restriction on competition.
