This is what I am wondering. It would make an interesting test case, refuse to accept the pensions changes post 2015. Now with the current state of aircrew retention allowance, with you losing 12 months worth on PVR, I dont think they could keep you in, especially if you couldnt afford the 12 month 20% in pay.
All these pensions changes are targetted against civil servants with very few transferrable skills to the outside world. Either they have to throw the dog a bone with some pretty huge targetted FRI's or they are going to have to gap capability.
I dont intend to stay if they tax our gratuity and I will use the change in terms and conditions as the means to get out.
