It’s a start. 7 hr days more closely match school hours than 9-10 hr days. Plus 4 wks of vaca plus holidays will at least allow parents to take trips with kids and/or spend time with them during school breaks. Lastly, 35 hr weeks may allow for four day flex weeks for a lot more workers. Work 8.5 hr four days, take one day off to be with kids. If two parents do that on different days, then you end up having a parent around four days out of seven.
See my second part about income expectations — we should actually lower expectations, painful as that may be.
