Jimbo, FWIW, the lawyer most of the HKA guys used told us the bond was not legal, also you can not " sign your rights away ", in other words, if it is in the HK labour ordinance ( which it is ) you signing a bogus contract does not allow HKE to take away your rights.
Surely if your lawyer was correct, HKA would be chasing the 30 odd guys that have left for their bonds ? 30 X 250,000= a lot of money
