Hear me out!
I often think about how it might simplify things for alot of people if the "average" working day started at say 9.30 or 10.00.
When I was at college (many years ago) our class actually voted in favour of a later start time - it allowed parents to see children off to school before starting their day without having to source childcare early in the morning and work around a longer drop off (eg. Childminders, relatives, breakfast clubs).
I've always had jobs with irregular shift patterns so I'm by no means in a nice little 9-5 bubble but I do think there are many roles which follow this pattern and that it poses a problem for lots of parents.
Surely having a staggered start time to that sort of day would solve problems for alot of people - even if your own shifts don't follow such a pattern it might open up an oppertunity for friends, neighbours, relatives to help each other out more rather than dropping children off at breakfast clubs and childminders really early in the morning?
