Yep I understand that , what im trying to say is that they have to protect your right to stay at a certain place if personal circumstances dictate it , thus the mobile grade issue is one that is now a little obsolete under new Eupropean laws. So if you need to stay at a place and no job exists there any longer you would have to be amply compensated.
I don't know the ins and outs of it but already someone in NATS management has raised that issue regarding a different set of circumstances but to explain why they are no longer able to do something that was originally in the Staff manual.
Its worth investigating all avenues for those who may have to lose their jobs.
