VICTORIA As Vancouver Island saw a surge in new COVID-19 exposures at schools this week, several teachers unions are renewing a call for new safety measures. Unions in Nanaimo and Victoria say extensions or alterations to the upcoming winter break could give teachers and families more of a chance to isolate. We know that students and their families are spending time with others against the health orders, said Nanaimo and District Teachers Association President, Denise Wood. That s creating issues. Teachers are asking for an extension to the normal holiday break to give families that might bend rules this holiday season, more of a chance to quarantine before coming back to class.
