David vs Goliath
In a comment to "The $160,000,000 Gorilla", Mr. Wainscotting points out that we live in a democracy and the unions have a perfect right to lobby on behalf of their members. He further suggests that people with opposing views go out and support the campaigns of political candidates with whom they agree.
Of course, Mr. W is right about the democracy part, but he is not taking into consideration the disproportionate amount of power wielded by the teachers' unions. Here are some of the government and school board policies that give the unions an unfair (IMHO) advantage and render them arguably the most powerful political lobby in Ontario.
1. In order to teach in Ontario, people must join a teachers' union. This gives the unions a guaranteed flow of revenue and power no matter what they do.
2. The school boards collect individual teachers' union dues on behalf of the union, thereby saving the union the considerable expense of collecting their monthly dues and keeping records. It also eliminates the possibility of teachers defaulting on their payments.
3. Teachers continue to be paid by the school board when they leave the classroom to conduct union business. And if teachers take a prolonged leave of absence to work as a union official, the clock keeps running in terms of their retirement benefits and seniority. This saves the union a lot of money and makes it easier to recruit union stewards.
4. The school boards give the unions privileged access in terms of using their facilities for meetings, mailings, and posting information. There is also typically a time slot at staff meetings for union announcements.
5. The provincial government contributes significant amounts of money to the teachers' unions every year for various activities.
Taking all of these subsidies into account, the annual revenues of the Ontario teachers' unions are realistically equivalent to well over two hundred million dollars. Against this, the amount of money and power individual citizens can wield pales into insignificance.




Here is a NP article, addressing another point that should be added to the 5 above.
“Indeed. Walker understands that a one-time giveback means little. The state’s financial straits — a $3.6 billion budget shortfall over the next two years — did not come out of nowhere. They came largely from a half-century power imbalance between the unions and the politicians with whom they collectively bargain.
In the private sector, the capitalist knows that when he negotiates with the union, if he gives away the store, he loses his shirt. In the public sector, the politicians who approve any deal have none of their own money at stake. On the contrary, the more favorably they dispose of union demands, the more likely they are to be the beneficiary of union largesse in the next election. It’s the perfect cozy setup.
To redress these perverse incentives that benefit both negotiating parties at the expense of the taxpayer, Walker’s bill would restrict future government-union negotiations to wages only. Excluded from negotiations would be benefits, the more easily hidden sweeteners that come due long after the politicians who negotiated them are gone. The bill would also require that unions be recertified every year and that dues be voluntary.”

It is the relationship between the politicians and the public sector unions that creates an imbalance of power that favours teachers unions and other public sector unions.
