The IAC rubber-stamping the so called "agreement" is a forgone conclusion.
Many will leave after the back-pay is settled, may it be the full amount or just 6 months.
The pilots who can do both talk and action are those who have alternative employment lined up or who are no longer bonded.
If flight ops think that crew morale is low now (mdv has said that there is no problem with morale as no flight has been cancelled or delayed, still having enough crew to fly), wait till after SQ ram the "agreement" through IAC.
The idea is to pi$$-off those on a higher pay scale encumbent batch and replace them with new pilots who draws minimum pay to keep the cost down.
