If by seniority you are referring to pilot seniority, then please do tell how a different system would work? Should we be filling out KPI reports as we are conducting the ILS on the 6th sector of the day?
As pretty much everyone else has said, you need to get some FACTS into the public domain, preferably on the same day as the QF spin gets released.
Explain things like subload, like the average payrises you have had previously, like the fact crew rest cant be used for joe public anyway etc.....
