I transitioned so long ago that I barely remember office dynamics/politics at the job where I transitioned. Since that time, I've found myself in jobs where I'm either in a position of authority, or I'm in an all-female environment. (I presently work for a large order of Catholic nuns; my boss is the only man in the administration building, and he has immense respect and admiration for me.)
Here's a funny thing though. For over 10 years prior to transition, I was a truck and car mechanic; I even owned my own shop for a few years. Ever since transition, I find that whenever I have to take my car to a shop, the mechanics talk down to me as if I couldn't possibly comprehend what they're talking about. I once went with my father to drop his car off for repairs (he wanted me there because he didn't understand what the mechanics were talking about and he wanted to lean on my expertise.) The mechanic we met with would only address my father. At first when I asked questions, he would just ignore me. As I persisted in asking questions, the mechanic began answering my questions but to my father. So I'd ask a question, and the mechanic would give my father the answer. He acted as if I wasn't even standing there. It was very bazaar.
I hate to admit it, but I'm mostly okay with men talking down to me. I'm sort of submissive by nature, and I always prefer to be taken care of and protected generally speaking. Sometimes, like when dealing with mechanics for instance, I see my soft spoken submissive nature as a super power. I occasionally find it helpful to let mechanics and service people assume I know nothing about things mechanical/automotive; sometimes their assumption will bring out their inner protector and they'll bend over backwards to take care of me, and other times I'll catch dishonest mechanics with their guard down. Heck, if these guys are going to underestimate me, why shouldn't I use their misogynistic attitudes to my advantage?
I know; I should be ashamed of myself. I guess I'm just a femme fatale at heart.
