Not _at all_ true where I work.

I work with folks who have kids and folks that don't. There is absolutely no sign of this. I interact with a fairly large group of people; everybody is understanding and supportive.

Now. Perhaps I'm in a lucky bubble here, and it's different in other places. Perhaps the article is click-bait. Hard to know.

In the end it seems rather pointless to build up resentment this way anyway. There is so much evidence that a good work-live balance has a greater impact on productivity than skill - engineers who work less often get done more.

Managers who do not understand that should, frankly, do something else.
