BBXX I genuinely don't mean this in an offensive way, just a realistic/pragmatic/honest way...

Very, very few trans women are actually passing. Often, in polite society, people will pretend it to be the case, but it just isn't. Most individuals who have been through male puberty simply don't convincingly pass as women.

Testosterone has a huge effect on body development which is why the opposite problem I posed above is true - when a biological female has been on testosterone for a few years they will become very masculine and many will convincingly pass as male. It's also why it's very difficult for trans men to detransition (after a few years of T they will ALWAYS look masculine).

There are some obvious biological reasons for this. Male hormones have a huge transformative effect t on the human body in a way that female hormones (or removal of male hormones) does not.

But yeah. Tl;Dr there are going to be very few situations where a trans person is "outed" as trans to their coworkers because of this.

There are definitely plenty of other human moral/ethical concerns but I don't think this is one.
