Don't forget that in the last survey, "intention to stay" was at 48%, which the DFO saw as a positive point.
Nevermind that 52% are actively looking at other jobs.
Even a 30% pay raise wouldn't stop most from leaving, knowing well how the company can cut their contracts at will.
The problem is not a recruitment issue, it is a retention issue.
Give us our old contract (like any other airline in the world did) and maybe we'll talk.
