It's ridiculous to suggest that anyone working as part of a team can do it, in my opinion. I completely understand that it solves problems for the parents themselves in terms of childcare costs etc., and that's why they think it's great, but there is a noticeable difference in a team environment when you have team members doing it(people constantly away from their desks during 'normal' working hours). It creates frustration in a collaborative environment, in my experience.
It was unavoidable during Covid for a lot of people, but I really don't think it's a feasible strategy long term. If everyone was in the exact same situation, then maybe there could be a solution based on redefining common work hours, but when the majority of the work force either don't have kids, or have kids that don't need constant minding, I don't see how it works.
