I get it, I truly do. But no one needs to pick a school hours job. You can use childminding services or wraparound care, which if you’re working full time is affordable. If you’re on a low income you can claim a good portion back via universal credit too. Again, I did that for a while until I worked my way up the career ladder so it is definitely doable if you want it
No, you don't get it. Your posts indicate you have one child. At one point, I had a child in nursery, one in an infant school and one in a junior school. That's three drop offs/pick ups at three slightly different times in three different places and only when that had been acheived was I able to try and get to work on time. I had a car and it was impossible. Imagine doing it on public transport.
Not all schools have wrap around care and where they do there can be a long waiting list. Finding a childminder who can fit your child in on the days you need, let alone fit in 3 children, can be difficult. Again, waiting lists can be an issue. Matching childcare to start a new job, particularly if you haven't been working, isn't easy.
I don't have any knowledge on Universal Credit but childcare costs are capped on Tax Credits. So again, probably fine with one child if you're not in London or the South East but if you have 3 children to pay for (and where I am, morning/after school childminders charge at least half a day to cover their costs because of the numbers issue and not being able to fill the space during the day if they're taking your child later on), even covering 80% of the cost doesn't help if after the first £150 you're having to pay the full amount on minimum wage.
Don't get me wrong, I have worked full time for the last 10 years and have juggled and juggled but I was fortunate to have school wraparound and as I teach, school holidays off. I'm not reliant on minimum wage work and for a number of those years, had my mum to help out if I was ill. I am now managing a serious, life-threatening condition in one of my children without my mum and things have become very tricky because I am constantly being called out of school for my own child's needs where his school struggles to manage. We are hopeful things will settle but if they don't, I will have to re-consider what to do.
If you have been single and juggled the childcare etc. you really should have the ability to realise that for some people, it just isn't possible.
