Whatever you think of them being open, the fact is that with thousands of group gatherings of non mask wearing, non socially distanced, non personal distanced, non handwashing people for hours and hours every day in poorly ventilated building, this thing will continue to spread
On top of that, sleepovers and parties and play dates will continue to happen because ‘they’re in school together anyway’. Do you know how often parents say ‘They're in the same bubble’ like it’s a magical force field?
Families with a mix of primary and secondary kids will allow the secondary kids to meet up even if they’re not in school because what’s the point stopping them when the younger kid is exposed to hundreds of families a day anyway? How can they justify its ‘not safe’ to their teens?
Parents will meet up at the school gates twice a day and stand and chat. Some will also meet in their houses, as their kids are friends and sitting together all day anyway so they know that any Covid family 1 has is most likely going to be spread to family 2 anyway.
Parents will do more things, go more places and take more risks because ‘If we’re going to get it from anywhere it will most likely be from school anyway’.
Ditto teachers. And who can blame them? Teachers should have full access to all of society even under lockdown IMO as they’re not being granted safety in any shape or form so should at least be allowed to have their lives.
Employers will expect employees in in a way that they wouldn’t be able to if primaries were off. But schools are open so there will be an expectation of presenteeism in many many workplaces.
Roads will continue to be busy with schools in so people will get a general feeling of ‘business as usual’ and they will carry on cramming themselves into unnecessary shops.
You might disagree with some of the above. I do. But that’s what is going to happen and there will be many deaths as a result.
