This going on much longer will render teachers obsolete. One would think the unions might want to avoid over-playing their hand.The teachers are the ones more worried about schools staying opened. There have been sporadic infections in Australian schools usually only one or two kids or one teacher, and one much larger outbreak in a school which was immediately closed for extra cleaning while self isolation and testing went on. Don't think there have been any Australian fatalities re schools so far. Australia has been using temporary closures, extra cleaning and online learning re schools but initially all schools were closed except for parents who had to work and could not make alternative arrangements for their children.
