I have recently moved from one employer in SE Asia to another. The airline I left has no union representation and a weak operating authority. Most of the time I flew for them I considered myself fatigued and this fatigue was one of the reasons I sought alternative employment. I now fly for an airline that has good management, union representation and a strong operating authority. Guess what? Little or no fatigue and sufficient post flight rest (legally required by the authority) to recover completely before the next long haul.
And the strange thing is, its my new employer that is making record profits and the ex employer that continues to struggle.
There has to be a moral there somewhere.
