Just for once we have to stand up and say NO with a strong voice. The result may indeed lead us to industrial action, but lets cross that bridge when it happens. Don't forget the last thing the airlines want is looming strike with summer approaching. The pressure they would apply to PB and his minions will be considerable.
Lets get that dry powder out and use it, or at least threaten to use it.
2% is unacceptable unless PB and every manager is getting the same, which they wont.
I can only say that where I work its a pretty much solid no vote.
