Transport issues, childcare etc is not a valid excuse in my view - people are already managing these for the twelve hours they currently do so will just need to adapt for a further three.
Where I live there is one bus service running between Town A and Town B. It takes 90 minutes to get from A to B, a distance of around 15 miles. If you want to go elsewhere then you need to get a connecting bus at either Town A or Town B, the availability and timetabling of these connecting buses varies greatly. First bus in the morning is at 6am, it runs every 30 minutes until 6pm at which point it runs every hour until 10pm. After 10pm there are no buses. On Sundays the first bus is at 9am, they run once an hour, and last bus is at 9pm. On some Bank Holidays they run to Sunday timetable and on other Bank Holidays they don't run at all - for example this Christmas there is no bus after 5pm on Christmas Eve and New Years Eve and no bus at all on the 25th, 26th, 27th of December and the 1st and 2nd of January (the Bank Holidays).
They're expensive too. £6.80 return for an adult, £3.40 per child. This only covers you for that operator, the connecting buses at Town A and Town B are both operated by a different company and so need their own tickets.
As for childcare, we have one nursery for ages 0-3 and it's closing this month due to no longer being financially viable. School nursery starts age 3 but is only mornings 9am to 12pm. There is wrap around care at the First School, limited to 40 places and only available up to Year 4 (age 8 to 9). The middle school (age 9+) doesn't have wrap around care. There are eight childminders locally, they all have a waiting list and none of them serves the middle school so, again, only up to Year Four/age 8-9.
Back when I worked full time I had to get the DC up at 430, then preschool aged, and get them fed and dressed and take them to my mum's for 530 so I could get the 6am bus to work (no staff parking available), DH also got this bus. Mum would look after the DC until 8am when the childminder opened and drop them there on her own way to work. Childminder closed at 5pm so mum would collect DC on her way home and feed them at hers. DH and I would get back at 6, collect DC, take them home for bed and then do it all again the next day. It was exhausting and there is nothing more shut than having to drag a sleepy toddler out at 5am on a winter morning when really they should be in bed.
