TORONTO -- The union representing Ontario's public high school teachers says it will hold another one-day strike on Dec. 11.

The Ontario Secondary School Teachers' Federation says the job action will impact only schools in Toronto and several other regions.

Earlier this week, the union held a one-day strike that closed all high schools -- and some elementary schools -- across the province.

High school teachers are pushing back against government plans to increase class sizes and introduce mandatory e-learning courses.

But the Progressive Conservative government says the key issue at the bargaining table is compensation

The province has offered a one-per-cent annual wage increase, but the union is seeking around two per cent.
