Some rather sad views being expressed but in many ways I understand why. If Manchester management had been half honest with their staff in the last 3 years much of this "debate" would not be taking place.
The final decision to move MACC into the then NSC was taken and published by the NATS board in October 2001. The fact that the Manchester management have failed to convey that simple fact and the associated business case is for MACC staff to ask of their managers.
It will be Prestwick and not another site because in addition to the fine MACC staff there will be over 600 of the present staff who will be working at NPC. Nobody has ever even contemplated a business case which moves the lot.
For the purposes of anything to do with NATS ATCOs, engineers and ATSAs are mobile grades. Those same mobile grades were moved to Swanwick and will be moving, without choice, from TC to Swanwick. I have to agree with other posts that you can choose to move to Prestwick or resign. There are no other logical offers.
If you read the notice on sabbaticals it quite clearly says that Operational grades are very unlikely to be included and read that to mean if you are an ATCO you can forget it.
