Perhaps I don't see the problem correctly? A bunch of people who are in a final salary pension scheme are striking because the scheme has been closed to new starters ie people who don't yet work for BAA.
Correct, you don't see the problem correctly.
I think you'll find there's a bit more to it than that. Specifically, the way it has been handled, an announcement, no negotiation, and for members of the current scheme, a guarantee of no changes, initially.......... then, well not for 6 years, then Oh, OK, not for 10 years. None of which was ever mentioned when the original announcement was made.
The management style has changed enormously over the last 3 years, from aviation knowledgable to short term, process driven.
Trust is the problem here.
