The union representing 55,000 education workers in Ontario schools has reached a tentative deal with the province in central talks.

The union is calling an end to its province-wide work-to-rule job action.

CUPE members have been without a contract since Aug. 31, 2014.

Education Minister Liz Sandals says in a statement that the deal is net zero, which means any salary increases are offset through savings elsewhere.

 Sandals, who is not at the legislature today as staff say she is "actively" supporting bargaining, won't release the terms of the deal until it is ratified.

 The Liberal government had threatened to dock the pay of support staff represented by CUPE and the Ontario Secondary School Teachers' Federation, as well as the Elementary Teachers' Federation of Ontario, if they didn't end their work-to-rule campaigns.

 Premier Kathleen Wynne had said that if the unions didn't end their administrative strikes by Nov. 1, she would give permission to school boards to trigger five days' notice to dock their pay.

CUPE has been bargaining under a new process whereby central negotiations are happening concurrently with talks at board levels across the province.  

The tentative agreement covers central issues negotiated on behalf of education workers in all four school board systems: English public and Catholic, and French public and Catholic.

Details of the settlement will not be released until members have had the opportunity to review it and conduct a ratification vote.

The members in the school board sector work as educational assistants, custodians, office administrators, early childhood educators, tradespeople, instructors, library technicians, speech pathologists, it specialists and other classifications.
