Threads about prejudice against women always miss the real underlying problem.
Our workplaces - and most of life - operate to the assumption that everyone's a healthy male aged 25-50. Also that this male has the background functionalities of his life handled by someone else.
The working world was set up by such men, and still views them as ideal employees: they fit perfectly into the system created by them, for them. Everything else is seen as an aberration, a failing, a weakness.
Adjustment policies are one way of trying to even this up a little. Other ways would have to be a hell of a lot more radical. With luck, a following wind and a lot of litigation, we might end up with a system that facilitates everyone to work productively while taking a fruitful, active part in the rest of their lives, too. We aren't there yet.
Since no woman is the default male, every step of women's working lives has been fought for, resisted and litigated. My generation did the heavy work here, but the job isn't finished ... and 'the patriarchy' still resists it, looking for excuses to reward only the work of default males. Anyone who thinks women are now safely on a level playing field is a bloody idiot.
It's bloody idiotic to promote the idea that women should try at all times to appear the same as men (does a man with boobs, wearing a skirt, remind you of anything else?) The female physique differs from the male. Women have periods, pregnancies and miscarriages, give birth, breastfeed, have more complicated reproductive and hormonal systems requiring more medical attention, go through menopause, face a heavier load of social expectations including childcare, elder care and domestic duties, are more subject to sexual assault and harassment and more likely to suffer domestic abuse.
If you're a woman - or a man who wants women and/or children in his life - and you insist that women should attempt to fit the ideal male template if they want the same rewards as that male - you're a fool.
