I signed a paper that states I cannot work for any of my employers competitors for two years, is it legal and can I be sued if I take a job offer?

This is not a simple question. To answer it, you should sit down with an attorney and review all of the surrounding facts. I can make a few general comments. This kind of agreement is not favored in the law. The courts will enforce it only if it is reasonable, in terms of the actual legitimate business interests of the employer. For example, it is more reasonable to have this agreement with an employee who has access to business information, such as customer lists, than with someone who does not have any confidential information. The length of time, and the geographic area must both be no longer, or larger, than necessary to protect the employer from actual harm. If the agreement was entered into after your employment began, there may be a necessity that you received something in return for signing. Putting aside the question of how much he might recover in damages, this is not the kind of debt for which your employer could garnish your wages.
