Whether you strike or not over O/S will come down to whether you give value to BA's word. The dispute is about a written agreement, sch. K. In it BA gives it's word to work with it's pilots to "enable BALPA to proceed with confidence that the interests of Pilot Officers are being and will be protected and enhanced...". In exchange "BALPA agrees not to inhibit the deployment of aircraft for best commercial or economic advantage..." and basically not get in the way of BA making pots of money.
Sch.K only works if there is honesty of intention on both sides. To this aim BA agree to keep in regular confidential communication with a select BACC panel. The spirit of the agreement is that BA/BALPA won't make under-hand changes that affect the aims of sch. K, whilst acknowledging the need to move with the times. With this equality of arms BA/BALPA can enter any discussions knowing the facts and intentions.
Well BA mentioned P/L (O/S) in the spring yet wouldn't even discuss it until December when they had already started recruiting. If you look outside the Heathrow goldfish bowl their are glaring examples of what happens when an airline turns it's affection on a younger willing sibbling. JAL/JALways, Qantas/Jetstar, Iberia/Clickair, Cathay Pacific/Dragon Air. All OneWorld.
If you believe that BA's word is it's seal then there is no need to strike. If you think they haven't honoured Sch.K then only a complete fool would trust their latest O/S Summary Document promises.
I think their word is a crock of s
