I've posted a bit about this over the past few days on the MN response to Spartacus thread in site stuff, but someone suggested I start a new thread about it here.
Earlier this week I was surprised to encounter an apparently male person in the women's loos at work. I understand from a colleague that they have just started the transitioning process, and it appears from all the research I have done that there is no way to avoid them invading our space. It would be discriminatory to prevent them.
We also have showers, presumably the same applies. I plan to take it up with HR, since none of the women in the building were told this could happen, but I haven't managed to speak to anyone about it yet.
I feel angry, powerless, silenced. It's obvious using the next cubicle that they use the toilet as a man would. We will have to adapt our behaviour, hide any discomfort so as not to make them feel uncomfortable. There are unisex accessible loos on every floor, but no, they want to be in ours.
