It is very difficult to put myself in the position of a FR pilot. It is very easy to say how I would behave, what I would do, from the sidelines and with the comfort of working for a company that has union recognition. I certainly don't envy you guys (unless I become unemployed!).
I don't know the in's and out's of what has gone on before with Balpa and Ialpa. What I do know is that I have better T's and C's working for my lot because of our CC and membership (since 2001). We don't win all of our battles by any stretch of the imagination, but we do win some, and find a lot of middle ground on others, and of course lose the rest.
Maybe the opportunity for recognition for you guys is totally lost, as Ryanairpilot says I do not know first hand. But surely it is worth giving them another chance (even if they did drop you in it first time around), keeping the hope alive that there is a possibility of recognition.
