Um. So, I've read the article. My TL;DR:
There is no scientific research on the adequacy of the current working schedule, as it was adopted arbitrarily by managers. Furthermore, it was established by men for men, without asking women for input, which makes juggling family, career, relationships... difficult for women.
Yeah, there's a wonkish phrase in the middle of it, which reeks of pseudo-evo-psych. I'm talking about "it’s well-established that men perform more effectively under routine and structure." So what.
