I’m not sure what you mean by the hours- there are lots of full time jobs that lots of parents simply can’t do around pick up & drop off, plus needing time off for holidays or paying for childcare.
2 of my friends had to leave their jobs when their children started school, 1 because she couldn’t do the job between the hours of 9am and 3pm, the nature of the job was set shifts which were no longer possible and the other because once she factored in the cost of breakfast & after school club plus clubs for school holidays it didn’t make financial sense to continue.
I also have a friend currently looking for a new job with a 4 year old and despite having plenty of experience and skill, her job search is hugely limited because she needs to find a job that is between the hours of 9 & 3pm, Mon-Fri which either pays enough to fund holiday childcare OR has enough annual leave for her to cover the holidays herself- the job doesn’t exist. She has said multiple times that her options for work would be massively different if she had reliable childcare from 8-5, and through school holidays, she could actually work most jobs at that point. But once she has to factor in the cost of all the clubs it’s not viable.
It’s not uncommon for parents to work full time to afford life, especially these days. They see their children the same time everybody else does, before and after work. Lots of things are important for children, but high up on that list is a roof over their heads and food in their tummy.
I’m not saying it’s the perfect answer but it would allow parents to look at a much wider range of jobs, rather than looking for a unicorn.
