Kikko,
For your information, NSP will result in anyone from LGW being able to apply for transfer to either WW or Eurofleet. They will now be able to retain their seniority and see their general terms and conditions change also.
As you are aware, there is an issue as BA has a pool of external people awaiting placements to Eurofleet. Although we all feel for them they have simply received the offer of a job; no formal contract has been signed. For this reason, BA are well within their rights to amend their offer to LGW and if that offer is declined they can simply state that this is their final (and only) offer. My view is that this is what they will do as NSP will not allow them to recruit externally for LHR again - unlike they did a number of months ago. This really would cause uproar. They have already been warned of the possible implications such an action will have.
