I am a Chair of Governors, and absolutely agree with what Luckygirl says. The schools have been preparing all Christmas for their return. Schools are absolutely safe for children, that is not the issue.
The problem is that, with this new variant, the pupils may act as a vector for transmission back to families. In the village we know that many people did not follow the rules over Christmas and New Year, and now there is a sharp rise in cases locally which means pupils are more likely to be carrying back to families who have been obeying the rules.
I understand how important it is that children are back to school, I was a headteacher myself once. Many children are not supported to learn at home, and many pupils are also safer in school if they come from homes where, sadly, they might be abused or neglected.
In addition, the gap between disadvantaged pupils and others has widened by 40%, there are tragic long term consequences for them.
This situation is terribly stressful for staff who are criticised whatever they do, and who are actually at risk themselves - many of them are vulnerable to infection too.
It is right that the government is trying its best to keep schools open for the sake of the pupils - I don't think playing a blame game is helpful for anyone. It is a complex situation which is changing from hour to hour.
