I would never condone breaking a contract delibrately with the intent of getting a type and leaving; however, sometimes life changes and you need to change jobs for whatever reason. Last full time flying job I had was a 12 month pro-rated contract. Left at month 8 (with a full type) for family reasons and offered to write a check for the additional months when I turned in my manuals. Got a "you were a good employee and we appreciate your candor, but that's not required." In a nutshell they waived it. Had a lot to do with my attitude about it I believe.
