Ask a parent (usually mother) what happens if they try to bring a kid to their (non coronavirus era) office because they don't have anyone else to care for the kid that day. Almost always completely unacceptable, for reasons ranging from arbitrary fake professionalism to lack of interest in setting up a support structure and expecting employees to sacrifice their personal lives for the company.
I can only hope this "fake macho work persona" bubble-burst carries forward into post-covid.
I will try to overlook the sexism in your posting. In my company, its not umgingen that someone brings their kid to work. Be it to show the kids what they are doing all day, or because of some logistics thing, or daycare closed or whatnot. Never a problem. Also not uncommon to work from home for the same reason. And it's usually the men who do that (sorry if that doesn't fit into your stereotype).
