You do not have to accommodate under the Americans with Disabilities Act. I know how hard this situation may be for you and the co-workers of this individual, because a member of my family is transexual. From all the medical literature I've read, this is a condition that has been known to humans since the beginning of time. In many cultures, including the Native American, transexuals were honored as having two spirits. My personal feeling is that you should do all you can to educate yourself and the workers about this condition, and treat this person respectfully as the woman she sees herself to be.
