"Sleeping with an instructor to advance her career" is just a bit of an unfounded inference.
How do we know Starfleet prohibits such things? How do we know her relationship with Spock is anything but genuine?
Her field is xenolinguistics, which implies a fascination with alien cultures. So she shows up one day in Vulcan class and here's this smokin' hot guy who's an alien (well, half, but that's even more exotic). Why wouldn't she go after him like a tribble after quadrum tritocale? I sure would.
Unlike practically every other Trek romance I can think of, Spock/Uhura actually comes off as convincing. Uhura is a consistent, coherent character in the movie: strong, capable, not afraid to get her way, committed to a serious relationship with Spock, which looks like it's reciprocated, and contemptuous of idiot males. As a good-looking female, that last part is inevitable.
I'm sure Kirk is not the first drunk fool to give her good reason for that contempt.
