That's the point — most don't, and most men don't seem to understand why it's a problem (your comment above is not atypical).

I'm not sure how this proves the point that the lack of such policies at tech companies discourages women from working there. Only one company has been mentioned as offering this policy, and it's a major tech company. Are there others? Are there fields where it is common?

I've never heard of it before now, and I worked for years as a corporate lawyer. And my lack of awareness isn't because I'm a man, as you've implied — my wife has also never heard of such a policy (and she works outside tech). Both of us have heavily researched the leave policies in our respective fields, as we have used them on multiple occasions.

If there are a bunch of non-tech companies offering this policy, then perhaps that could lead to your conclusion that it's one of the reasons women choose other fields. But based on what has been described so far, it's equally likely that this is an incredibly rare policy that does pull people into or push people from the tech sector. If there are sectors where this is common, please enlighten us!
