QF graded wage scale
From what I've read and am aware of your system although not perfect allows you to move up a grade over time (4 years). This in effect pays you for experience on type, consider the possibility of no movement once at that grade. If you aren't deemed worthy of another type, you will only get an increase at EBA.
How would you feel that having held a license for 4 years, gained experience to be able to diagnose and fix problems faster than somebody who has held the license for a week. Yet you are on the same pay.
Sunnies have locked their guys down forever at the same point - only interested in the standard EBA inc 3%/year for ever. Also trying to stitch up next aircraft payment before you know type (turboprop or jet).
Be very careful with tweaking the GWS
