This question is purely out of curiousity - not to say I would EVER consider it because I live by pretty high moral standards - but what if someone just walked away and said 'to hell with you, I'm not paying you $7,500'. Is GLA going to take you to small claims court? From what I've heard from some people is that unless a bank note is attached and it is amortized appropriately - there is no legal 'stick' that companies can use to get the employee to pay that back...
