The problem that the employees have is that every section of the airline thinks that they run it.
I have seen time and again one section working against each other or at least not helping during a dispute.
Each section is only interested in themselves and the company not only knows it but is happy to help that along.
Divide and conquer.
What would be the best for us all would be for a single airline employees union however for the obvious self interest,political and egotistical reasons that will never happen.
