As long as everyone is actually on the same page with regards to what a salary increase actually is. Inflation corrections on your salary are not salary increases. They are compensation for the constant devaluation of money over time. Not compensating for inflation would be a pay cut, not a pay "freeze" as is being suggested. I expect the DPA will be hammering this With whomever they will be negotiating.
With regards to these productivity gains I keep reading about it's fairly simple: Gain them by increasing efficiency. We still have a lot to gain there if we do 170 duty hours for 75 block hours and 30 to 40 sectors.
Looks pretty straight forward from where I sit.
