My prediction for the next chapter.
ICAO & Airline pressure force Airservices to close Airspace on a scheduled basis due safety concerns over the incidents you havent heard about yet.
Airservices blame this on 'renegade' controllers, but cannot identify them, and will not answer questions when pushed by an irritated media what they are doing to manage these staff.
More controllers leave, and less are inclined to go the extra mile anymore.
Airservices refuse to negotiate an attractive contract when it comes up for renewal in December. Pissed off controllers withdraw their overtime to start with over the New Year period.
Even more closures.
Airservices blame controllers - "It was theire plan all along"
Government finally tells them to act, and stops taking sides with management.
CEO resigns.
New CEO arrives promising to 'restructure", 'Worlds Best practice', etc. etc.
Airspace still is closed.
There are no controllers left to blame anymore.
