TORONTO — Ontario has reached an agreement in principle with some high school support staff who have been on a work-to-rule campaign for nearly two months. A spokeswoman for the education minister says the agreement in principle was reached "pending internal approvals and ratification by the parties." A deal with the school support staff represented by the Ontario Secondary School Teachers' Federation is one of the last ones to be reached in this round of education-sector bargaining. The majority of support staff in Ontario are represented by the Canadian Union of Public Employees, which reached a deal earlier this month with the province. The province also reached a tentative deal Friday with Elementary Teachers' Federation of Ontario education workers, such as early childhood educators. Education Minister Liz Sandals says in a statement that the deal is net zero, which means any salary increases are offset through other savings.
