I am new to nursing myself, having spent 20+ years as an oil field deep-sea diver. Overall, men seem to make more at my facility. One thing I noticed when interviewing and when discussing the hiring process with my cohort, was that the men at my facility and my school were better prepared for wage negotiation, having researched the pay matrix and highlighting experience that would help the initial salary, whereas the women were more interested in the personal and connection side of the interview. Not a single woman from my class was aware of the pay, pay matrix, or benefits being offered ahead of time, but every man was. I also know that I make more than most with the same experience because I did not accept the initial offer, counterproposing, and getting about 8% more. I don't know if this holds true everywhere, but from my personal experience men are more likely to ask for more, request raises, change positions for pay, etc. than women.
