I agree that you definitely should consult an attorney on this question. The answer, based on what you have said, is a frustrating "Maybe, maybe not." The first question is whether the contract language even restricts what you want to do in the first place. If it does, then the second question is whether the contract language is enforceable. In Wisconsin, restrictive covenants are not per se unenforceable, but that can change if they are overbroad or unreasonable. What constitutes overbreadth and unreasonableness is the subject of hundreds of cases and depends on the facts and circumstances of every situation. The standards are intentionally vague because almost no two fact situations are alike. Best of luck and I hope this works out for you! Go see a lawyer! Next time you sign an employment contract, have a lawyer review it first.
