I could have done but haven’t. I’m a KW but DH works from home. We just couldn’t justify it.
I’m amazed, though, at how many kids are in (both in my kids’ school and in the school where I work). I think it’s partly because so many parents and kids found lockdown learning so hard last time.
But also I think it is because, as a society, we’re just so conditioned to take care of ourselves and our families first and foremost.
So most people are going ‘yay, I can technically have a key worker space, it’ll make my child’s/my life easier, I’ll take it!’
And not ‘actually, I could technically have a key worker space, but the right thing to do for society overall is for me to keep DC at home.’
People seem to have, as a general rule, a mentality like @JackyReacher. The ‘I’m entitled to it so I’ll take it’ attitude. Arguably, no parent should be sending a child to school unless they are definitively vulnerable (SEN, ECHP etc) or if both parents are KW. But most people seem to just be thinking of themselves and their DC. Not the wider issue. You can see the responses all over MN - all sorts of excuses about why THEIR situation, THEIR family, THEIR child is different and therefore deserving - but very often their reasons boil down to ‘It makes our lives easier.’
