Any CC is made up of those who are willing to stand up and represent their colleagues. Anyone can stand for CC elections and they are held every year. If the end result is a collection of people of more senior background round then either they are the only ones standing or they have previously gained the respect of their colleagues (or both). I believe the case in easyJet to be both.
If an individual on the CC has failed to respond to emails there's probably a good reason for it but in any case it can be easily rectified by using the CC group email address or go to the National Officer.
If you really want the answers to legitimate questions then get involved in (or start) debates on the BALPA forums.
It's pretty crass to create a new pprune ID just so you can accuse somebody of taking backhanders. If you really think this sort of thing goes on in Balpa circles then you have an awful lot to learn. For the record I'm not on the easyJet CC either but they deserve better than this
