A general rule of thumb for work is as long as your job gets done and you aren't creating a distraction you'll probably be OK, to a point. I've heard from others in my group many times now, how basically people either ignore, haven't a clue, or just don't really or see much of anything going on. Yeah, you're looking or dressing a little different. Perhaps the rumor mill is settling in on going gay. That they can deal with. Boobs, hair, even nails won't mean much. Unless you have a lot of direct customer contact.
The moment of truth comes when it comes to which toilet you want/need to use. That is when all the ranting, gnashing of teeth, rending of clothes, and general uproar tends to start. It might be just the bosses/owners, or an uproar swelling from the users. In an area with no trans protections there is likely absolutely nothing you can do about it legally. Now, if your company has some "Diversity" statement which is referenced in their employee handbook that also includes "gender identity", you may have an wedge. I haven't done any research into who has tried this route yet.
Time for the bubble burst portion - Having been in upper management,as well as having seen life from the trenches, I can assure you any company, any boss, in any state, with any/all trans protection laws, WILL find a legitimate business reason to terminate you, if they no longer want you around, no matter what value you may be to the company. There are the few rare cases of a PHB actually putting being trans on paper, almost all are not that dumb.
