How many would leave if the rise was 1/1/1 for all, not many.
The current deal.
It's targeted at retention not fairness or inflation. If it is rejected then in 6 months time there will be an inferior one on the table, perhaps no back dating. If it is accepted then the next target will be xxx and pitched accordingly. This is no longer a career airline and has not been for several years.
Reject the offer and see no pay correction for years, but will perhaps make the co think twice about axing too quickly.
The present CEO is intent on cutting costs our salaries are in his gun sight.
