I'm gonna give you one last post, once again you prove my point. It's not a "revolving door policy". Did you know teachers aren't even aloud to restrain a violent kid? So when the **** head is physically harming a teacher, the teacher can't even push him back to defend them selves? Can't physically restrain them from bashing another kid? So while these kids are at school (which every australian citizen has a right to be) there is no way to control them apart from saying no you can't do that (you can suspend them all you want but it doesn't do anything, why? because wait... The parents can't even punish a kid these days for mucking up at school!). If you can not see something wrong with that then you need a effing reality check. Get in the real world and go ask some teachers, hell if you want I will go to my mums work and hand out a survey and post the results.
The union is as limp wristed as this goverment that rules us. They don't even represent the view of the people they are supposed to be representing (FYI I also know the NT Education unions top person).
