RAFAT
Back in the 90's when there was no pay to fly and bonds were the way training finance was conducted there was a lot of speculation about the restraint of trade issue.
With the number of pilots who left companies before the end of the bond period I was always surprised that no pilot ever ended up in court with the company trying to recover the bond.
The only conclusion that I could come to is that the companies did not want to test the bond contract in open court, what usually happened is the both parties agreed on a settlement and a privacy clause so the true value of the bond did not become public knowledge.
The truth of the matter is that this issue will only be resolved if some one takes it to court.
