From what I hear, there's fault on both sides (as there usually is in these matters).
CX management is to blame for taking advantage of their people over the rostering situation - and especially with the 5:1 ratio. Sure, the current contract offers higher basic pay - but does it improve the standby ratio?
On the other hand, the union (AOA) is to blame for its intransigence over the seniority system - despite the fact that it is well aware that in order to alleviate the rostering problems, a large number of additional rated and experienced pilots are required.
To make matters worse, I understand that the 'lunatics' (in the form of the '49ers') are currently 'running the asylum' at the AOA in the absence of its president - which is simply worsening relations between the AOA and CX management.
I think some binding independent arbitration is called for as soon as possible - problem is, will either side go for it?
