Well BALPA can ask, and I've seen suggestions that company chairmen be sent letters by employees asking for assurances that pension obligations will be fulfilled. All very well, but they will either:
Ignore (most likely)
or
Say "No."
End of Chapter 1
What next? I don't like it any more than you do, but BALPA, along with other unions, is doing what it can in the face of hostile, anti-employee rules and a Government that doesn't like you having your own pension (it doesn't wantto give you one either, but that is a different story).
I'd already been to this website and read this- it told me nothing we didn't already know and have discussed in the BALPA forum. We know about it and it's not new- it's just a shock when realisation comes.
So, ball in your court!
