Mamaput, I think we are basically saying the same thing. The gentleman who was told he could not work in Nigeria....did he not want to work elsewhere? If no, then why did he apply? Government and unions are involved too when you work in your home country.
As I said, apples and oranges.
AFAIK, he probably does better financially working in Nigeria than he would elsewhere.
Again, as a Nigerian national ETB isn't a CHC employee. Local management has clearly established that. The first step would be to apply to CHC (or Bristow, Heli-Union, etc) and once accepted resign from ACN. Then he would be just like the rest of us, without representation and living the life of adventure.
Not picking on you ETB, just the example at hand.
