As a 'napster' I am really sad to see the apparent lack of support for 'barpers'! (I hope, from a vocal minority!). I voted against the pension proposals of balpa. These effectively led to the creation of the quite appalling barp. It was a disgrace then, and still is.
Hand Solo may be correct that barpers will "be in the minority by some margin for at least ten years" But bear this in mind. Once they approach 50% BA will be after your naps pension again. If I were a barper, when considering whether to go on strike to protect somebody else's pension I couldn't avoid remembering how supportive they were of my predicament.
Don't be stupid guys, if you are a napster much below 50 years old, retiring on naps will depend on the support of barpers!
They need you now and sooner or later, you're going to need them!
