Yes Ozzie,
Reflecting on your post, institutionalised is the perfect way of describing your typical ATC in the centres. As morale plummets ATC's adopt the wonderful Australian trait of turning on their own.
There a very few people on any one group you can trust as self interest becomes the guiding principle.
Don't believe the BS rhetoric from your union either, they're as bad as the managers described from ASA, once again self interest rules.
