Some of the responses on here - good grief, #bekind didn't hang around long did it!
Its horrible for schools trying to manage through this pandemic. As a school governor I see the efforts in our primary school to keep kids in school, to try and offer wraparound care in September so parents can work, and I also see how knackered and upset the teaching staff are from trying to work this all out. Its really hard on them and I don't think anyone is out to blame schools.
However I can also see where the OP is coming from. I'm a single parent too, there is just one childminder (who's full) locally who collects from the primary school where I have children who as of September will be in reception and year 2. I am faced with 1/2 days for the first 8 days back, one has mornings, one has afternoons. Its wreaked havoc with my working hours, so I'm taking that week off to basically do school runs all day. Can't afford a holiday anyway!
When they go back full time they're on staggered start and finishes 20 mins apart. School run in the morning will take me an hour, same in the afternoon. I have a full time job, but admittedly do have flexibility and can work from home. However, this will really impact on my working day, I cant expect my employer to pay me for doing nothing, so I make up my hours every evening. Wraparound care has doubled in price to staff it safely, and I've been on a pay cut of 15% since the start of April. I think if school told me they were closing 1/2 a day a week and I'd got to find childcare or take unpaid leave I'd cry....
I get it OP. Comments about school not being childcare, not liking your own kids, its not all about you - not helpful, and probably not made by full time working single parents who would understand exactly where you're coming from.
