@SpanishPork are you suggesting that the unions are behind year bubbles, no social distancing, no masks, no blended learning, return of the vulnerable. etc. Not protecting the interests of members would be perverse. OTOH government blaming the unions for their failure is par for the course.
The illogical language is telling - DC will not be 'forced' to wear masks in school. All hail freedom. But, they will be 'forced' to remove them at the school gate having been 'forced' to wear masks on the journey to school? If viral transmission is within households where time is spent with the same people, why not workplaces, why not schools? From the POV of transmission the rules make no sense.
Issues of space and equipment are practical problems easily overcome. Those with no space can be classed as vulnerable and able to attend closed schools or other venues could be used. There is no need for specialist equipment - bog standard equipment and broadband are fine. Those without can receive laptops and internet access. The scorn heaped upon JC pre-COVID about inequality of broadband access doesn't seem so silly and irrelevant now.
Your assertion that secondary aged DC somehow can't work from home in the context of online supported learning is just an assertion. They really can. They can even be more productive. Just like slightly older people can work from home and be more productive. Who knew?
I'm not saying the case is the same if you have younger DC. Being in two places at once is a 'problem' not effected by COVID.
Often with older DC, it is just an issue of parental confidence thinking that there is some magic involved in teaching and that you can't possibly do it even when you have the time or don't need to actively teach or supervise all the time and the resources are easily found. I do have to personally supervise and support and couldn't do it if it weren't for the vast amount of resources that are freely available online. This is just sharing best practice and school teachers do it too. Personally I find maths the hardest because I hit my limit long before DS2 (14) who already has a GCSE and is moving on to A level. Internet/home schooled BTW.
Lack of parental confidence is a real fear that is exacerbated by the threat of fines or being told that you have to deregister and take full responsibility with no support. DS2 is SEND - I have faced this.
It doesn't have to be black/white, either/or. In exceptional circumstances or exceptional times it is possible to find a way of supporting DC and their families and communities.
I really hope that force of numbers will mean that the concerns of a large minority will have greater effect than the concerns of a smaller minority. I also hope that the large minority will not have to become the majority for their concerns to be seriously addressed as it doesn't seem their is currently a plan B.
