I think lots of people are using the 'lots of places closed during covid' as an excuse, sorry.
The reason is people don't want to pay. And I don't blame them, who would want to pay £50+ a day childcare if they can get away with wfh and keeping the child in the house. That's the same whether it's a COL crisis or not, if someone has the money or not - 99% of people would rather spend the money elsewhere.
I think having kids over say,8 or 9 at home is probably okay if they can be trusted to do their own thing with telly, toys, iPads etc, if there really is no other choice.
But where does it end though? People don't want to pay train tickets for the commute so they want to wfh. People don't want to buy lunch, get up 2 hours earlier, have the commute home etc. None of those reasons are bad as long as the production level is the same as in the office.
But when people don't want to pay childcare so they wfh, it gets dangerous as that could hard production levels. Maybe some roles you can, if you genuinely can work your own hours, but most you can't do with a young child there.
I worry where these demands will go in the end. People are already declining meetings at my company because they have to do the school run at 3pm. In their mind, their childcare needs come before meetings and work even during core hours.
In the end it will be wrecked for all of us and wfh jobs will become a rarity again. Before covid wfh just one day per week was a rare privilege in many companies and happened after you had proven yourself after a flexible working request. Now it's taken for granted.
When we are all ordered back to the office we will all be harmed - the childless people who work well from home, the mums who save 2 hours on their commute and can currently take their child to school / pick up their child from school/nursery earlier than they would in the office, the cash strapped people who are only surviving due to wfh and saving money on train fares, and just anyone else who prefers being in their own environment than a busy office. We will all lose.
