Discrimination against men in employment

I trust this post to a large extent (though I also understand that no sources were provided with it) as I have seen job openings specifically for women (as in it was written in the advertisement itself that only women could apply- have seen this kind of thing 2-3 times in the last 6 months ) .Based on what I have read- the wage gap seems to be mainly caused by women temporarily leaving the workforce while they’re pregnant and after having children ( https://www.google.com/amp/s/www.vox.com/platform/amp/2018/2/19/17018380/gender-wage-gap-childcare-penalty ) but for more than half a decade now, it has been implied by media, activists etc that it is primarily due to a bias against women. This has led them to try and combat a bias that never existed to the extent that they think it did. So, this explains the CS part of this person’s experiment. The second part was about customer facing jobs, in which I think women are preferred usually. I think someone should repeat what this person did and properly record their experiences etc.

Note- want to it clear that I am 100% for more spending on childcare by governments and companies, which is something that would actually close the wage gap.
