A huge amount of teachers, esp primary, live in a bubble of school and then unwinding when they can, not engaging in any political stuff, don't read papers etc. If they do it's the guardian. Many full timers in primary are millennial women, they don't join unions, don't strike, senior leadership teams can now be anyone under 35 or 30 in some places.
I know you acknowledged the stereotype but even taking out the fact that we are a pretty unionised staff, with under 35 GC members of SLT (eg: me) included, our most non-GC colleagues are about 35-50. Sometimes they are part time women but more often the most non-GC are male. I have wondered if it is something to do with how in our school, more girls are identifying as male, and so right now there are few implications. Our students are kind and largely compliant, and so will use any new name without question; they enjoy campaigning for social issues; and the trans boys will use the couple of private, single toilets around the school and change in separate areas of the school. Therefore for your average teacher, it doesn't appear to be much of an issue.
For those reasons, our school has been able to hold off on the toilets issue, but I wonder if we're not going to be able to do so much longer and I am very prepared to be vocal about it when we have to, especially now we have more (older) boys identifying as female.
So it's heartening to read that many young people are not buying into this. It's a shame that looking at this forum it seems to be boys that are more GC, as girls need to be comfortable vocalising their criticism, but it's a real start and, as I said in my previous post, shows the vocal cries of the "Miss, you can't say that there's two sexes, that's discrimination!" aren't representative.
