How will it end?
How indeed?
One of BA's problems is that, having bent over backwards in years gone by to be "super inclusive" and accommodate virtually every kind of employment type they have now made themselves hostages to fortune.
There are a significant number of very part time CC (50% or even 30%) who are, effectively "hobby jobbers". Over the years they have been nurtured on the "grievance" drivel that has passed for union comms from BASSA and now have a deep and abiding sense of injustice and entitlement. They also have (usually) someone else paying the bills at home and can therefore stay out for as long as they want.
I know that many people claim that part timers have a lower sickness rate than anyone else (which is not saying much, frankly!) and are therefore more "loyal" than others, but I am not so sure.
Given that one full time NF recruit could, potentially, replace up to 3 "hobby jobbers", mass sackings must be becoming an increasingly attractive proposition to WW. After all, he can demonstrate to 10 decimal places how reasonable he has been in trying to resolve this dispute, and that compulsory redundancies have now become his only choice.
