I have heard that they wouldn't stand up in a court of law if they tried to go after you. I asked a company that I interviewed with about a contract. They said they don't make you sign one because their lawyer told them that a contract wasn't valid. The reason they gave was that they couldn't hire you and put you in aircraft that you never flown before. So they didn't make you sign one until they upgraded you. Because they sent all there new hires to SIC school and didn't type you. If you want to leave before it expires try and get your new employer to pay it off. If they want you bad enough they will do that for you. I hear of places doing that all the time. Hope this rambling makes sense. I tried to make it. Good Luck.
