The one day, rotating strikes by Ontario elementary teachers has hit the Upper Canada District School Board, along with three other provincial boards.

Roughly 18,000 students with the UCDSB won’t have classes or regular programs, but schools are open and supervision will be provided.

The last day of planned strikes for teachers is Thursday, with educators in Kingston, London, Brockville and northern Ontario staging a walkout.

The rotating teacher walkouts have now affected every public school board in the province.

Upper Canada board members met Wednesday night and passed a motion calling on Education Minister Laurel Broten to retain a mediator to speed up the bargaining process with teachers.

Meanwhile, Broten said she wants to see the union that represents public elementary school teachers do more bargaining and less time planning job actions.

Broten also said any strike action by teachers in the new year will be illegal.

The Elementary Teachers’ Federation of Ontario (ETFO) said there will be a province-wide day of protest next year if the government uses Bill 115 to impose a contract on them.

The ETFO has scheduled a news conference for Friday to announce details of its next steps in its ongoing labour dispute with the provincial government.

Meanwhile, a spokeswoman for the union representing public high school teachers says its members are voting this week on whether to support a day of political protest against Bill 115.
