I understand that relief teachers often feel a bit isolated and Education Departments don't support relief teachers much. They pretty much play the political game for all their employees but relief teachers don't seem to figure heavily in their support structure.
But a forum with other relief teachers might be a way of sharing common concerns and get new ideas.
I found this forum which is specific for relief teachers - well this section is anyway. (Beware though - there is a bit of bitching and complaining as well).
It's called Whirlpool Forums but this section is just for Relief Teachers - CLICK HERE to check it out.
