Another teachers union is about to start rotating strike action.
The Ontario English Catholic Teachers' Association will walk off the job next week, if a deal is not reached with the province beforehand.
The Niagara Catholic District School Board will be targeted on Monday February 24th.
The OECTA will also be taking part in a province-wide walkout with three other teachers unions this Friday.
This will close all Niagara Catholic and DSBN elementary and high schools.
