I don't understand the psych of ASA controllers. If you don't want to work on your rostered day off - then DON'T. It's quite simple. If you do then I am guessing they are the one's not complaining.
The problem appears to be that there is more than enough controllers willing to work constant extra hours, have little in the way of a social life, give half of their earnings to the government and keep ASA management operating with a bare bones roster. This is a time bomb that will go off eventually where two airplanes will come together because of controller fatigue after working so many extra shifts he/she doesn't know what day of the week it is!
Oh yeah, and I bet somewhere in the contract it says it is the responsibility of the controller to identify and acknowledge when they are not fit for duty!
Maybe the union is too weak to handle the might of ASA upper management!!!
I do know that there are a few Aus-expat controllers in Canada that have a little black cross sitting next to there name? Don't think they will be coming home to nest anytime soon!
