I for one have faith in what he does say as since 1997, when the last big change was to foisted on us, we did stop this attempt to protect the rice-bowls of ASA employees at the time.
Rice bowl? That's a funny one
ASA is as busy as a one legged man in an arse kicking competition. They don't need work practices protected, they are a monopoly provider with steady increases of traffic year on year plus major projects. They provide separation in mandated airspace, any more of it and you are creating more work for them.
Charged back to you of course.
Apart from the fact that as much as you'll hate to hear it, Australian controllers are probably the most productive considering the size of their sectors and the traffic numbers.
