I can understand the point on leadership roles largely being men in some fields like government and finance, much as in education and mental health leadership is largely women - but the UK is a country with a significantly majority White population so any equitable balance of leadership would still be mostly White here.
Who brought race into it? Marjority white isn't the issue here. Majority men is. And as pp said: in jobs/professions where there are a lot of women (teachers, nurses) you will often find men come in and then move up through the ranks swiftly (for many reasons) and women are doing all the grunt work while they are "managing"
Here's everyday sexism. I was in the army a long time ago. In a job and a place that was vastly majority men. We did all the things they did including guard duty, going out on exercise for weeks on end, sweeping leaves etc etc. There was a lot of overt sexism. Often a lot of groping there was sexual assault the works.
Now we're all in various fb groups and once one of the chaps said "well we were ok, you lot never complained, did you?" and we all said "fuck no you weren't fine and we did complain. A lot. And everything was ignored, swept under the carpet or we were 'managed out' or just made out to be liars"
And believe me, it didn't go down well. But we were ALL (women) saying it, and reminding each other, in the groups "remember x when y..." until they just all told us to stop.
That is what we're up against.
