It depends on the state that you live in and when you were hired.  When I was hired by EDJ, the contract was minimal and filled with loopholes.  Also - in my state of residence, there is a contract clause whereby if one item of the employment contract fails to comply with state law, the entire contract is null and void.  You should consult a lawyer for your situation to be safe.  I do know they have gone after FAs before for such expenses, but I've yet to hear a case where they actually won or received punitive or compensatory damages.
