How is it arrogance??
Lets look at the facts here.
Are your T's and C's under threat here in the ROI? NO
Is management asking you to take a pay cut? NO
Is management trying to alter your work practices? NO
The are simply trying to set up a base in another jurisdiction and hire crews under local conditions.
Yet in spite of all this, you are willing to ground your airline. The lost revenue, the screwing your customers, many of whom may never return and not just out of anger but because they will be unsure about using AL again if this action continues and also the potential damage this could do to your fellow workers.
I am painting the other side of the picture. And yet somehow this constitutes "trolling"!
(*internet chatroom rule No. 156. When someone disagrees with your viewpoint, accuse them of trolling)
It beggars belief.
