(1) millions of children will suffer poorer mental health, educational deficits and be at risk of physical harm.
Unfortunately many children are at risk mentally and physically regardless of whether schools are open or closed - and I'm afraid to inform you that the education system in this country has inequality built into it. If you are so concerned about these things I can only assume you have been pushing for greater funding for mental health services and domestic abuse services - and NOT voting for any party that cuts them - and campaigning for the abolition of private schools and a restructuring of an education system that middle-class parents game for their own benefit? And that you will continue to do so after the pandemic?
(2) if schools close now the government will struggle to get them back open.
The government will only struggle to reopen them if they continue to be unsafe. If the government doesn't fuck up the vaccine rollout any more than they already have, and prioritises teachers, and funds school safety, there will be no problem. No one WANTS schools shut.
(3) the unions are playing a highly political game preying shamelessly on people’s fears.
This is a meaningless sentence straight out of the Daily Mail Anti-Left Fearmongering playbook. The unions are standing up for their members, as they should. Do you not fundamentally understand that unions are a positive and necessary force in terms of workers' rights? Or do you think that unions are just aggravating irritants and workers should just shut up and accept a shit lot?
(4) online learning is of no use for most of the primary school years. Parents basically need to be available all day to support children.
(5) more parents are going to find themselves unable to work causing more financial hardship. This won’t affect your middle class sahps or people who can work from home as much- there are people who actually have to go out of their house to earn a living.
True. There should be more support for parents who find themselves stuck between a rock and a hard place now. The target of your ire should be the government, whose responsibility it is to enable people to abide by the restrictions necessary to combat a pandemic.
(7) educational transmission of the virus is low and infection control standards can be escalated where needed.
Well this last one is where your entire argument falls apart isn't it. Because it's just not remotely true, not backed up by numbers or evidence or what we can all see with our own eyes.
