Children attending Sudbury public elementary schools won't be in class on Friday as teachers across the province will hold a one-day protest over Bill 115.
They will voice their displeasure over legislation the provincial government put in place that imposes a contract on teachers.
As a result, the Rainbow District School Board in Sudbury has cancelled classes for Friday.
The president of the local union that represents elementary teachers with the Rainbow Board in Sudbury said "some people are very concerned that this is an illegal strike."
"We aren't in a legal strike position," Barb Blasutti said.
"That's obvious, because the minister has imposed terms and conditions upon us. This … is a political protest. It's directed at the government, and members will be exercising their right to protest this Friday."
The union said 92 per cent of its members voted in favour of the one day protest.
