Ottawa's public school board has resumed talks with the union representing high school teachers in hopes of negotiating an agreement that will help end labour disruptions at the schools.

Ottawa Carleton District School Board chair Jennifer McKenzie told reporters at a board meeting Tuesday night that local bargaining talks have resumed the Ontario Secondary School Teachers’ Federation and that talks are scheduled with the bargaining units of local elementary teachers.

Public school teachers across Ontario have been taking part in a work-to-rule campaign to protest against the provincial Liberal government. The government legislated changes earlier this year that curb the ability of teachers' unions to strike and freeze wages.

Under the job action, which has not occurred in all schools, many teachers are forgoing administrative duties and other selected tasks, including the volunteer organization of sports teams and other clubs.

Board director Jennifer Adams wrote in a Tuesday night news release that several school districts have already worked with local teachers' to negotiate tentative agreements that the province supports.

The deadline for Ottawa's public board to come to an agreement with its unions is Dec. 31, 2012.

"The school district remains committed to negotiating a local agreement with our bargaining units by the legislated deadline," wrote Adams.

While talks have resumed with teachers, the union representing school support workers — including custodians, education assistants, secretaries — said they have voted 88 per cent in favour of strike action.

The Canadian Union of Public Employees said while some school boards have reached tentative agreements with teachers' unions, their union has not been involved in those negotiations.
