Every day this week, thousands of Ontario students will be out of school. Rotating one-day strikes will hit every school board in the province in the biggest escalation yet of a labour war that's been raging for almost six months. At issue? Class size, salaries, mandatory E-Learning, and other issues on which the teachers and the provincial government share no common ground. So how long can this go on? What's behind the latest tactics, both by teachers and the government? Who's winning the battle for the hearts and minds of parents across Ontario? And is there any hope of a happy ending?
