I do not agree with this at all. Unless the unions are going to support teachers teaching via online video calls.
But this has been done to death, online video calls all day only suit a tiny number of people. Why on earth can't you support videos which can be accessed at any point in the day? Then all the people who need to support their children in the evenings and weekends can access the learning too. It's people like you who bleated "my child is not plugged in 9-3, so my school are doing nothing" who make life hard for the vast majority who are just trying to keep their children on track in the time they have available.
