High school teachers with the Keewatin-Patricia District School Board have started their job action.
That after talks between the Ontario Secondary School Teachers Federation and the public school board broke off earlier this week.
Paul Elliott is a vice-president with the OSSTF and says even though they aren't allowed to strike, they can still exercise some of their labor rights.
Elliott says teachers are being urged to withdraw from their administrative duties, until a new contract can be negotiated.
Meanwhile, the Keewatin-Patricia District School Board feels contract talks with its high school teachers had been going well.
However, the OSSTF shut down all negotiations this week after the provincial government refused to approve a couple of contracts that had already been negotiated with school boards in southern Ontario.
Union negotiators are scheduled to meet on Monday to decide their next steps.
