If the schools close they are shut. Schools are not equipped to deliver teaching online. Teachers have not been trained to teach online. Children are not equipped to learn online. The curriculum has not been designed to be taught online. If schools close then children will not be receiving an education. It is dishonest to pretend that they are.
So if the schools close then teachers should be furloughed and children's education should be paused at the point of closure. Closing schools should not be disguised as something it is not. This would allow the damage to continue indefinitely. If schools remain closed for a longer period then teachers should be made redundant so that they are free to do other work. This of course would be terrible and would hopefully not be allowed to happen... But then schools have already not been fully open for nearly a year.
