BALPA are now a backwards looking talking shop where everyone moans about how bad things have got with absolutely no culture of getting anything done about it at the fundamental level.
WHYEYEMAN, with all due respect (which in this case isn't very much) the makeup of BALPA has been amply explained above, and if things are not being done to your satisfaction then get off your idle arse and do something about it yourself instead of expecting to have it handed to you on a plate. If your CC is that bad only the membership in your company is to blame - no one else, but then your basic understanding of what a Union is and does is so wide of the mark I doubt you'd see yourself having a role in shaping your own future. If you can't be bothered to learn what a union is, let alone join in and help then please stop spouting such, er, bullshine, or just lift a finger elect more effective people into your CC. Do you see no irony at all in bemoaning "no action at the fundamental level????" That's YOU!
A change of attitude would cost nothing.
QED
Why can people not understand this simple concept? Post 9 is spot on - if nothing was illegal neither BALPA not the House of Lords can stop it.
In any case, does anyone suppose that easyjet or anyone else went bleating to BALPA in advance? Get real! About what? People with a legal right to work in UK being given employment? Have a care people, that table could equally turn on YOU! Only once the deal was done did it become public knowledge, I'll bet, and it's a bit late to initiate a discussion by then.
The iniquity here is one of respect for employees, and seniority and command prospects amongst existing FOs; shameful, underhand and appallingly bad for morale. All of that is very upsetting, but it ain't illegal. There will be nothing "binding" in the company's promotion policy, merely advisory, so what could possibly be done beyond a protest to the company who will only claim commercial necessity?
Work to rule perhaps?
