Background: My transition plan includes presenting as a guy at work until I'm ready for full-time, at which point I'll change jobs. I'm not particularly concerned that I'd lose my job were I to attempt transition in-place, but I've been planning to look for a sweeter deal since before deciding to transition.
The other day, my roommate pondered if there's danger of losing my job as I begin looking more like a girl from HRT. I said I don't think so, silly butt.

They won't fire someone because of how their face looks; just possibly if they start dressing as the opposite gender. But I've been rehashing it in my mind and I'm not so sure now. I mean, people have been fired for dressing like a girl while still looking like a guy, so isn't it logical to be fired for dressing like a guy while looking like a girl?
Has anybody heard about or had any incidents with this?
