If you have already signed an agreement, you'll want to carefully review it before you take a job with another company. Some who have failed to do this, are accused of violating their agreement and end up jobless. Besides becoming jobless, many who lose in court are also burdened with extensive legal fees. If you need to change jobs to advance your career you may need to consider doing it in a way that does not violate your Noncompete Agreement such as by moving to another region or changing industries. You may also be able to simply ask them to be released from the agreement. If they agree, get the release in writing.
