I live in New York, and commute to MA. It's equal distant to where I work in MA and Albany, NY. I make about 3 to 4 dollars per hour more than most hospitals in the Albany area for a person with my years of experience. This is because most hospitals in this area of MA are unionized whereas all hospitals in the Albany, NY area are not.
Now, I work in a small rural hospital located in the Berkshire Mountain area. (Right now this hospital is widely trying to keep its nurses, and to remain open too. Long story!
) I believe most if not all hospitals on the western side of MA are unionzied. I recently explored work for a couple of hospitals towards central MA. The two hospitals which I considered working at, again, were unioned and offered pretty good hourly rates.
I make a little over $30.00/hour including eve/night diff (I work 12 hour nights), 12+ years of nursing experience and a BS in Nursing.
Hope that this is helpful!
