Healthy teachers...are tough to find right now and the hunt may get harder still. As winter ills hit ..including covid, some schools are being forced to split classes or send students home as they struggle to find cover for unwell staff. On Thursday, Mt Cook School in central Wellington asked parents not to send their children to school because half its teachers were off sick with Covid. And they are not alone ..Wellington Regional Primary Principals Association confirmed the problem's been building, particularly over the last few weeks and other schools are findig it hard to get relievers too.
