Public secondary and elementary schools are closed, as labour strife continues between the province and various teachers' union.
The Ontario Secondary School Teachers' Federation (OSSTF) is withdrawing all services Thursday, the third one-day strike the union has staged since December.
Because OSSTF covers elementary support staff, the move has prompted the closure of all schools in the Avon Maitland District School Board.
President of the Teacher's Bargaining Unit with the OSSTF Avon Maitland, Shane Restall, says teachers are prepared to continue their work action until either a new contract is reached, or legislation forces teachers back into the classroom.
The walkout comes two weeks after the escalation of teacher walkouts by the union's counterparts in the Elementary Teachers' Federation of Ontario (ETFO).
ETFO is two weeks into twice-weekly strikes, as they, OSSTF, and two other unions continue to ramp up pressure for a new contract with the Ministry of Education.
Restall says escalating work action by others unions has done little for the OSSTF, as the province has not recently returned to the bargaining table with the union.
During Thursday's walkout, members of the OSSTF will be delivering letters to the constituency offices of Lisa Thompson, Huron-Bruce Progressive Conservative MPP, and Randy Pettapiece, Perth-Wellington Progressive Conservative MPP.
