It is completely achievable; it is only a trade dispute. The CSD's are working and there is a new fleet. The savings are made. All you need is arbitration for the dismissed and suspended workers and some creativity for staff travel..........
We seem to be at cross-purposes?
The original point you made was about there being various different contracts at LHR/LGW to which I responded that for new fleet being an entirely separate fleet was critical to achieving savings targets.
On the point you raise above, WW is unconvinced that if staff travel was restored BASSA would agree to the deal on the table.
On disciplinaries, I see no reason why there should be a departure from the established procedure. It is entirely proper that they are dealt with in this way, to do otherwise would create a dangerous precedent.
