The union representing 12,000 French teachers in Ontario has announced plans to begin a work-to-rule campaign this week.
The campaign from Association des enseignantes et des enseignants franco-ontariens will be similar to job action from other unions, including the withdrawal of some administrative tasks.
Union officials say student learning will not be impacted.
The latest announcement means every teachers' union in the province will be engaged in some form of job action as negotiations with the province are going poorly.
