This is a huge problem all over.
British laws make it so it's best to never, ever hire a woman under 55. Even women bosses don't like hiring breeding age women.
Feminist have fought and won to extend maternity leave and benefits for women, but have ignored the very real problems those same things are causing women in general.
Problem is that on a company's viewpoint, females in the breeding years end up causing more expenses than income and even if the ones in the positions of power are female themselves they have to answer for the company's profits. At least here is not unheard of women taking maternity leave and being skipped for promotions (contacts and influence and the usual dark inner workings of work environments aside)
Dunno what would happen in one of your 3rd wave feminist countries (though I'm pretty sure it would involve suing, accusing of sexism and whatnot). Also makes me wonder how those 'women-only' or 'female-mayority' companies work.
