For me it is not just about cubicles, but the room. What happens if I spill coffee on my blouse and need to change, or want to get ready for something after work.
Its fine. PPs, Aimee Challenor, BBC bosses and Pips Bunce would all, presumably, tell me that it is fine.
They won't ask me because I am only a women and in their world I am not entitled to a view.
The BBC has lots of buildings. My bet is that there is more choice of provision in larger buildings. Gender neutral toilets are not a problem at DH's work as their building has male, female and gender neutral on each floor. He claims not to have seen anyone use the last, which says a bit about preferences. In contrast I met someone working for a University whose building only has gender neutral loos, and who regularly sees female, muslim and overseas students walking out in the rain to go to the single sex. Discrimination in action, or have we accepted that a small number of "influencers" get to dictate societal change over majority wishes.
