The minimum has been 12 hours a week, so four lunchtimes bar maiding a week entitled people to benefits.
Now it'll be five lunchtimes a week to give access to those benefits. It's hardly a major ask.
I'm a single mum, I've worked 40 hours a week since the end of maternity leave and it hasn't been a problem. I'm late 50s and still doing it. I carried on doing it while being treated for breast cancer so I'm struggling to see why people whose children do not have additional needs would find this an issue.
