BA have in the past given re-deployed people permanent places at WW LHR. An example that comes to mind is when the BFS base was closed. They were offered WW LHR as there was nowhere else for them to go at the time. As far as I know, those who took it are still there. This was around 2002/3 and they were already cabin crew, so that may have made a difference.
So have the rules changed or is this just a sneaky way of getting rid of staff without having to pay redundancy?
