Education workers in Ontario will begin a work to rule campaign Monday.
This comes after last-minute contract talks with the province this weekend failed to reach a deal.
Compensation, job security and funding for additional staffing - are some of the sticking points.
That means that some of the 55 thousand workers, including janitors, clerical staff and educational assistants will cut back on some of the services they provide.
Speaking to our media partner, CP24, Laura Walton, President CUPE's Ontario School Board Council of Unions, explains what Monday could look like:
"The administration's going to notice it the most. So, there will be no calling out early for supply staff and that will start when we get to work. There will be no coming early or staying late because that is unpaid time."
"Hallways will not be swept because at this point they're not being funded and that is resulting in us not having enough folks there, so those are some of the key pieces."
But other than that, Walton says, overall it will be business as usual.
TDSB spokesperson Ryan Bird echoes that, telling CP24, it's going to be school as normal for students.
"Students are not going to notice a huge difference - at least in the beginning."
"For us, what we have advised parents is as the partial withdrawal of services continues, it may have a more significant impact on things like school activities, permits and school operations."
And the union has previously told NEWSTALK 1010 that no CUPE member will ever do anything or omit any practice that makes a school unsafe or puts students at any risk.
