How to fight for a better package for new joiners?
Easy.
Don't allow the company to disrupt the roster of 5 pilots because they didn't want to call the reserve. Don't allow the company to call pilots on G days before all reserves are called out.
Wait... they don't have pilots on reserve anymore? Just roster more pilots for reserve duty.
Not enough pilots for that? Hire more
Not enough candidates? Improve the package
That's how we should get rid of C-scale.
