Elizabeth, my heart goes out to you. My daughters best friend and housemate has been teaching for four years in the government system and the dreams she built lie shattered.
She went to the same private school as my daughter, budget catholic with lay teachers, and really had no idea what the mosh pit was like.
Sounds like you may have upset the hierarchy in which case you might have to find some mates and start up your own school where education is the priority and you are not bound by regulations that are absurd. It is not such a dumb idea really. If you limited your class sizes to ten and charged $10k a year you would be able to rent pemises and collect a decent wage. There are penty of small schools shut down in NSW and more than enough dissillusioned parents.
The government system is by and large an absolute mess. This can only have been achieved deliberately. As the Doctor says, the protocols of Zion make very interesting reading.
I cannot help comparing todays system to the one I went through in South Africa. I went to Queens College, Tony Grieg, in primary school. Caning was administered but not abused and it kept the wildest manageable. School started at 7.20 am and went through to 1.30, hour for lunch then compulsory sport until 4.30 run by teachers who were also rostered on on saturdays to referee or umpire.
I then went to Kingswood College which is quite up market. We had prefect supervised early morning prep 6.30 to 7.15, breakfast, chapel 8-8.15, Classes through till 3.20, compulsory sport till 5 with Wednesday arvo off, then supervised prep from 6.15 until 9.30.
To cap it all we had four periods on a Saturday morning in winter and three in summer.
And if you try and tell the young folks that today they won; believe you

but the point I am making is that teachers did pretty big hours.
I know that if I had my time over I would home school my kids. Look at what it achieved for Jessica Watson.
