You are all concentrating on the monetary value of the bond.What about the fact the you are entering in to a commitment giving your WORD to stay for X amount of time.
I find that people who lie about there intentions knowingly intentending to foxtrot Oscar once the training is complete shows a lack of integrity that doesn't belong in a profession such ours .
Quite rightly walk from your bond and suffer the consequences.
Funnily enough the individuals that I have meet that have walked from bonds without paying the outstanding sum have all been the first out of the Taxi and last one in the Bar.
