The Elementary Teachers Federation of Ontario will hold a series of local meetings to prepare its members for a work-to-rule campaign that will start November 26.
The campaign is not expected to affect students, but rather ministry and school board administrative tasks.
"Our goal is to turn up the heat on Premier Ford and his Education Minister, Stephen Lecce. It's critical that they finally come to contract talks prepared to address the real issues of concern," said ETFO President Sam Hammond.
The union has identified issues like greater support in the classroom for students with special needs, protecting full-day kindergarten, and addressing violence in schools.
"We are making this known well in advance to assure parents that this strike action will not affect students, their learning, or their safety," continued Hammond. "ETFO members will be withdrawing from Ministry and school board administrative activities, which will give them more time to focus on working with students."
The results from strike votes held across the province in September and October showed 98 per cent of the union's members supported strike action if need be.
The union represents 83,000 elementary public school teachers, occasional teachers, and education support workers.
The union that represents Catholic teachers across Ontario released the results of a strike vote Wednesday. It said 97.1 per cent of its members were in favour of strike action if talks fail to reach a tentative agreement.
Talks between the Ontario English Catholic Teachers Association continue Thursday and Friday.
The Ontario Secondary School Teachers Federation also recently released the results of a vote showing strong support for strike action from its members.
