I also dont see why the OP is getting a pasting. In the olden days, mr man would work as he pleased, safe in the knowledge that wifey was at home to mop up all the childcare/housework/admin that needed doing, amd if not granny was just around the corner.
That world has gone. Now both parents are likely to work so getting to work and ensuring the kids are looked after is likely to be a very fine balance of both parents doing what they can around their work schedule, some paid childcare and a bit of informal family/friends. Disrupting this balance because work needs change is a total pain in the arse.
My work paid for my childcare expenses because my partner had no option but to work. However, had he not been working those weekends, the reality for him would have been working 4 long days, in a v senior job. Having to call in favours for pick up and drop off, and then having the kids by himself all weekend, several times in a short period of time. We both have busy periods in work, where we have to drop a few family things, but we then make it up to eachother. I don't think i could have made this stint back to him without breaking myself.
So, my work paid for someone else's labour to make up for my absence, but had hr not been working my partners labour to make up for my absence would have just been expected.
