I think you're getting a really hard time OP. All children deserve to be getting an education. In my kids school they have their class teacher teaching them Y3 work - yes it might be more limited than what they'd otherwise have, but it's a qualified teacher teaching the curriculum that most children in the class at home have no access to. They also have a condusive learning environment and friends.
We didn't use a key worker space last time, we swallowed it all - how staying home would help ALL kids get back to school faster and look what happened - our kids were welcomed in the pub and cinema before school which didn't let them back in until September. And even then the unions didn't want them back.
Some key workers absolutely have no option but to send their children to school and are working really hard in ridiculously bad circumstances - but most of the 200 children who were given a place at my kids school in May 2020 were not in that position and they were better off, it's why everyone that can has got a key worker letter this time because they can't bear keeping their children pretty much locked up for months. I know I can't.
And then there are those of us who work, whatever we work in..eventually it does all need doing. Many of us have been juggling this for over 6 months now in total, why we should listen to someone telling us it's a small sacrifice I don't know.
Who in society is completely voiceless, unionless, powerless and most vulnerable. Children. Who is speaking out for them? Pretty much only that Anne Longfield childrens commissioner.
Everyone feels happy now nipping to Tesco every 10 mins without a mask, grabbing a coffee and meeting a friend in the park now the children are locked up. Schools have already been closed for 3 weeks and are we seeing the fruits of our children's virtual imprisonment? No, because really you're not so likely to get covid in school as you are in Tesco.
Many teachers are fearful of their health, but many teachers are also taking the mick. My SIL has her two kids in nursery and she's on mat leave as a teacher. They're not all angelic, and they don't all care about your child. The only person that really cares about your child is you and your loved ones. So don't feel ashamed for speaking up for them, in my opinion it's a sign of a good mum!
