It's sad that this issue degraded the teachers into being and acting like a trade union, rather than a profession, but I suppose that was necessary in order to bring the government to its senses.

The politically correct pointy heads decided that every child, no matter how severely disadvantaged, had the right to be in every regular classroom, and then refused to follow through to fund the classroom supports necessary to make that work for ALL of the children in the class.  Christy Clark was the Minister of Education at the time and lead the charge (gleefully).
