When my oldest was born I worked at night (and was working at night anyway as a copy and news editor) and my wife went to school during the day. Then we moved for her residency and I got a traditional timed job, and had a second kid, so we had to do child care. It was insane then and we got a discount through her work. That only lasted a couple of years, I hated the job (first non-newspaper job but still journalism) and went full SAHD. I was doing it all anyway, and it truly was a money saver then, especially on a journalist's salary. And while I have worked off and on since that has basically been the setup. I've always been the primary caregiver and not sure how we would have made it otherwise.
Only two left in school out of four. I have had brushes with real office work recently and they are old enough for us to figure it out without too much issue, but it is still a factor. Being there for them, not the school babysitting. Amazing how many activities, especially school sports, are at like 3 on a Tuesday too.
Anyway, there is a balance on schools taking care of kids and working. The kids have to go to school, most people have to work. Kind of hard when there is a two-hour early start or release to figure it out for a lot of people.
I think I brought it up here, but our school district has a heat day schedule. It is mildly annoying because I think their guidelines are a little liberal of when it is too hot (the buildings get hot regardless) and then the whole starting two weeks earlier than they should. But my wife's work is the largest employer here and the school district is the second largest. So my wife's work has a policy if the school district is out you can take off without using any personal time, sick or vacation. So far every day this week has been a heat day, which is a two-hour early release. She said there wasn't a lot of coverage today.
