There is - or was - a feminist myth that women are cooperative and mutually supportive, and all the hierarchical bully bullshit is an essentially male trait.
I have worked in a university library, with mostly female staff, some sections all female.
I no longer believe this myth. Some sections were frankly vicious. I declined a promotion (more hours, better rate) because the all-woman team I would be joining was deeply internally hostile.
Mind you, despite the massive preponderance of women at lower and middle levels, the top two positions were held by men. Still.
(Hey, guys, you reckon we can blame the glass ceiling on women's mutual sabotage?
