As an interested observer, I cannot understand how employees of various BA divisions allow themselves to fall for the oldest trick in the book......divide and conquer.
Whether you like it or not, you all work for the same company, no matter which division or agreement you belong to. Surely the idea of going to work is to achieve the best remuneration possible so why are some employees trying to drag their collegues down to the lowest level. That is managements job.
Management will try to achieve this by quoting what they want to quote to achieve a result. Thus the Brymon division was far more efficient and profitable than BAR. Anybody could be if they were allowed to regularly cancel flights at short notice due little or no infrastructure in the way of standby crews,aircraft or technical support and then just hand over the ensuing mess to BA and BAR ground staff to sort out and pay for.
Stick together boys and girls.....it is the only way forward
