This flexibility and cost you are talking about is borne entirely by them as they rearrange their lives and attempt to make things work while men continue with barely any disruption.
I'm my opinion this is deep, unintentional, structural sexism. It is the biggest issue I have with articles like this.
Stamping out overt workplace harassment and sexism is barely the beginning. There are deep structures in place that have benefited men like me for millennia.
These need to be considered not as complicated side issues but as the core barrier to achieving equity (as opposed to equality) in these fields.
If the answer is no, then bigotry is at play. It's impossible to know this answer, so we should just make it painless to take time off. I know of plenty of academics who go on sabbatical, fall off the face of the earth, and ignore every department email for a year or however long. This process actually improves their career, not hinder it. Taking time off is harmless.
A 'career' is something pop singers and top athletes (male or female) have. They even have agents to manage those careers. But most people have a job; they do work, travail, tripalium.
The fact that people confuse the two is just capitalist propaganda.

Maybe I shouldn't be so surprised, since English still has the word "travails".
"Work" on the other hand means action, doing:

That's quite a difference: one is something no one wants, and the other is something everyone does.
"Labor" falls on the "travail" side, meaning exertion, pain:
Flexible hours impose large costs in terms of increased difficulty of coordination and communication and if you’re really serious about them you need to completely upend the organizational structure, like changing an on premise company to a fully remote one. There’s also a hard upper limit on your career because managers are the bottleneck for communication so they almost have to be available when active else is. Arrangements to make flexibility economically profitable are also often denounced, see Uber.
> Even if you disagree that there’s a problem here (and I think you’re wrong) how would these changes cause harm? Wouldn’t it just be a better world if people were less stressed by these things?
It would be a better world but flexibility imposes large costs. Obscenely convenient childcare is also far from a panacea. Sweden has cheap to free childcare and it’s available 24/7 for those whose jobs demand it. But while Sweden’s employment rate is very high it’s among the most sex segregated in the world and fertility isn’t noticeably different from countries that aren’t so generous, suggesting the effects on family formation are minimal.
