Not every point of Kevlondon's various points is ignorant.
There is an awful trend in employment world wide, which is often called the chase to the bottom. Lower prices means employers want to pay less for everything. Unfortunately it applies to many Labour markets.
Personally, I have always said that BA massively overdid this in its MF contracts, but they did have to reduce their Legacy costs. They did over do it, though, because the TU, (T & G/Unite/BASSA) let them do it. BASSA did try to defend Legacy crew, with mixed success, (won some, lost some) but failed miserably with MF.
I have no idea how MF crew survive in the South East.
