Sorry, it appears as though my initial understanding was "just a little" out.
All the Serco Staff on the Abu Dhabi (airports, which includes Al Ain but not the ACC) contract have been given notice, EXCEPT the ATC's. The ATC's have been told that Serco will "try" and get them positions elsewhere.
A serious attmept to help the staff ? or a means to make it difficult for the next contractor to fill positions? I do not know.....
