They are restructuring all business support into one entity which will deliver from a catalogue of services. In the restructure all posts are being redefined and many tasks are going away because new business services will not deliver them. Much of what I do is not in scope but my post is. There will be a rude awakening at my work when they realise they cannot get the same service.   

So there are X number of posts and Y number of people. All put into a pot with a matrix of selection criteria. My specific job is gone. I might succeed to another post, but it is doubtful. Even so it will likely be lower band, reduced hours or so far away as to make commute expensive or a combination of all 3.

Fun days.
