Teachers of the Renfrew District School Board walked out on the job, Thursday. All elementary public schools in that board were closed as a result.

It's the latest round of rotating one-day strikes by elementary teachers in Ontario.

In Arnprior, Mom Peggy Leger was looking for an activity for her 9-year-old twins who have the day off school because of the strike. The kids asked to join the picket line in support of the teachers.

“People against that are just thinking about themselves at the moment not what's going to happen,” says Rory Hogan.

Not all students agree. 11-year-old Hannah Fraser spent the day with friends and parents at a nearby toboggan hill.

“One day is fine but I'm going to miss all the extracurricular activites,” says Fraser.

The teachers are protesting Bill 115, which allows the province to impose a contract and stop the unions from striking. Even deeper than the bill are unresolved issues over moving up the salary grid, sick days, and banking sick leave towards retirement.

“We just want to be able to negotiate. Period. That was taken away from us. They don't want to talk to us, or even have a give and take,” says Madore.

Teacher Glenda Russett, who has worked for the board part-time for 23 years, has accumulated 9.62 years in experience. She doesn't make the 10 year cut to keep her banked sick leave.

"I feel I was lied to," says Russett.

Teachers of the York Region and Trillium Lakelands school board will also be out today.

This follows Wednesday's walkout by Ottawa public elementary teachers, which left nearly 50,000 students out of class.

The first week of walkouts will end Friday in Simcoe County, Kawartha Pine Ridge near Peterborough and Upper Grand around Guelph.

Ontario Premier Dalton McGuinty has said the government will not intervene as long as the walkouts only last for one day at a time.

The public teachers' union is giving at least 72-hours notice of any rotating strike.
