While rotating one-day strikes by Ontario teachers enter their second day, Hamilton public elementary teachers don't have a walkout date set.

"When we have a date, we will let our members and the boards know," said Lisa Hammond, president of the Hamilton-Wentworth unit of the Elementary Teachers' Federation of Ontario (ETFO), on Tuesday.

"Parents will have 72 hours' notice," she added.

Members of ETFO locals across the province are staging one-day strikes to protest Bill 115. The union has said the controversial new law that gives the Ontario government the power to stop strikes and impose a new collective agreement on staff.

Public elementary school staff in the Niagara and Keewatin-Patricia school districts walked out on Tuesday, while those in Ottawa-Carleton, Lakehead in Thunder Bay and Hastings-Prince Edward school districts will walk out on Wednesday.

The one-day strikes will move to school districts in Toronto's York Region, Trillium Lakelands and Renfrew on Thursday.

The governing Liberals have the power to end the strikes, but Premier Dalton McGuinty has said they won't intervene unless the walkouts go beyond one day.

The government has said it has legal documents ready to stop any strikes should they stretch beyond a single school day.

The premier has argued that with Ontario facing a $14.4-billion deficit, the province can't afford pay hikes for teachers.
