How to identify the similar-minded women at work?

How to find other feminists: Quite simple.

Suggest setting up a woman-only group, or a feminist group, see who goes for it. Say 'women's rights', use the word 'woman'.

Make no mention, at all, of males, when discussing women. Clearly and calmly focus on women.

Remember your focus is on women. You need use no qualifying words, no concessions to 'not all men', no waffle about identity or thoughts about men's feelings. Men are free to set up their own groups if they wish.

Feminists will show up. Anyone who tries to get you fired, sends death or rape threats, starts whanging on about inclusion of males - not them.

Just realised I assumed you meant a tech company when you said large and male dominated!

Hi Sybill, I too work in tech, although in a small company and in one in which we are too busy to talk about much other than work.

My daughter is early 20s and gets frustrated that all her friends share woke/be kind messages. It's an incredibly hard orthodoxy to argue against because people are scared of being on TWSOH.

Make it a Strike book - even more under the radar!

I do very much like the idea of the green scarves, purple ribbons and subversive copies of Mary’s book

"Carry an “adult human female” bag."

Too obvious I think. JK Rowling OK.

I think there is a good balance , with the trans people reporting feeling very supported, it really is just the extreme side of things that is objected to ( and the local transwoman was part of that )

Wouldn't it be useful if we could all use some kind of sign that means nothing, so we'd be invisible to everyone except those in the know?

A narrow purple ribbon tied around the handle of a handbag, maybe? Almost invisible to anyone who wasn't looking for it. An emerald green scarf dangling over the back of an office chair or worn during a Zoom. A copy of Mary Wollestoncraft's A Vindication of the Rights of Women left on a desk or prominent on the bookshelf for Teams meetings. I've just checked on Amazon and currently there's a copy with an orange cover. How about leaving an orange-covered book or an orange-coloured file on your desk? Could be anything, could be empty. You could take any old book and wrap it in a sheet of orange card or paper. Or just carry an orange file around with you wherever you go. Orange stands out: best chance of other women noticing, perhaps. Just keep passing the word on the every GC woman you know. It would be wonderful to walk into the office, wouldn't it, and be able to see a dozen orange files and green scarves that are invisible to most of your colleagues.

I think the diversity stuff doesnt work well in largely male environments, particularly science based rather than silicon valley where they love it and love policing it.
My husband's work tried introducing diversity stuff, committees and pronouns and it all got dropped as everyone ignored it and no one volunteered for any committees.
My work place is mixed and most people are openly GC.
In a large company I'd just chat to people and maybe make an occasional comment but look after yourself and your income.

JK Rowling book a good shout, zero risk strategy.

I work in a male dominated , scientific environment and have no need to out myself as the men clearly have no truck with it. Eg volunteered to identify as women to sort out the sex inbalance

Read a JK Rowling book in your tea break, and leave it prominently displayed on your desk. Carry an “adult human female” bag.
Start innocent conversations about why on earth rapists are allowed to choose a women’s prison to serve their sentence, and watch the responses you get?
