Not sure, status quo in the office has always been that people passing as male are he/him, people passing as female are she/her and everyone else is they/them (including groups of people homogeneous and heterogeneous alike)

That we’ve managed to conduct our society so far without using alternative pronouns such as “xi/xir” is a strong indication that it’s a neo-political construct and, while I might be sympathetic to the person who prefers to be called by those terms, I will not go out of my way to force everyone in the company to - they’re also usually referential (without the person present) and I will get them wrong myself too.
