Posters saying this is a project management role, so he will basically be ticking boxes, perhaps you should let Mr Grant know that? He thinks he's going to be fostering conversations, educating and engaging audiences.
In Jason Grant's own words:
"In a press release announcing his appointment, Grant said: “I think being a man will help me to break down barriers, reduce stigma and encourage more open discussions. Although affecting women directly, periods are an issue for everyone. We’ll also raise awareness of the menopause, which, although a natural process for women, has wider repercussions in the world of work and family.
“It’s time to normalise these topics and get real around the subject. I believe I can make progress by proving this isn’t just a female topic, encouraging conversations across all genders and educating and engaging new audiences.”
If he's simply managing that certain items are available in woman's loos (I guess mens loos too because "some men menstruate"..) there's not much discussion needed. A list of products made available online that every place with public toilets needs to provide and "mystery shoppers" to ensure they are as well as phone lines to call if they're not. Fines for non compliance and it would be sorted relatively quickly. That's not what Mr Grant seems to think he's going to be doing. Not anywhere near it in fact. At best he seems to be some kind of ambassador for period dignity.
