The Elementary Teachers' Federation of Ontario (EFTO), which represents some 76,000 teachers and has just been through eight months of unsuccessful negotiations with the province, is set to release details about the "strike action" it announced earlier this week at 2 p.m. ET.
"We will be implementing what we think is in the best interest of trying to move our negotiations forward," said EFTO president Sam Hammond.
A bargaining bulletin obtained by CBC News suggested the strike action will be a work-to-rule campaign that won't cancel school but will make some differences inside schools. Teachers may refuse to nix written comments on report cards and avoid staff meetings during the campaign.
EFTO has so far declined to announce firm plans. Whatever happens will affect some 800,000 elementary students across Ontario.
While parents know schools will be open, parents are still concerned about the last-minute changes to their children's schooling.
"There's not a lot of information for me at the moment," said Gordon.
"Really, in the last couple of days, it's the first I've heard about a possible strike."
Education Minister Liz Sandals says it's "unfair" of the union to announce its plans so late.
"We shouldn't put parents through this uncertainty, we shouldn't put children through this uncertainty because this is really a dispute amongst the adults," Sandals said.
She said she'll consider amending the legislation surrounding teacher strikes so unions, like EFTO, must divulge more information about their strikes.
