The Elementary Teachers Federation of Ontario has confirmed that it is to ramp up job action as of Monday.
The Union has also advised teachers to prepare for rotating strikes in October.
In a bargaining bulletin released Friday, the union is warning that if a deal is not reached by Monday phase three of job action will get underway.
The escalation in job action will see teachers ceasing to respond to emails from administrators unless it involves a safety concern or to report their own absence.
They have also been ordered to cease preparing comments for report cards or progress reports and will not be allowed to update classroom websites or blogs.
Meetings with parents will also stop unless there is a serious concern about a pupil’s progress.
The bulletin orders the wearing of union insignia and attendance at rallies, while specific job action will take place on Wednesday’s, dubbed ‘Wynne Wednesdays”, when teachers will not engage in any activity outside of the classroom.
No further talks with the province have been scheduled after negotiations broke down last week.
