The ethics committee?
What ethics? When the majority of those on it's board were aware and even participated in the previous management scams?
GF, will be GF, until proven otherwise, practices and ethics aren't going anywhere and neither is the airline.
In the case of the ground staff inolved in the scam I would have fired everyone up to the VP, because it simply shows incompetency at every level, this pracitce of shielding some and berrating others is show only.
