BG the offer to undertake WW767 on EF was on a bidding basis and aimed to alleviate the removal of 2 PSR pos on WW .Thus trying to avoid an end to promotion.As to the promises, that is exactly the essence of the problem is that they are aspirational and unlikely to be contractual.In light of the recent court case to establish which parts of the agreements were contractual. The company's legal team argued that what they deemed contractual was your basic pay,annual leave and sick pay.Anything else is a nicety and not a contractual right.This was partly accepted by the Judge.
It's not so bad if you are SCCM on an old contract it very bad if you are main crew on post 97 contract.
