Need some advice!

Im currently in the application phase for a nurse manager or clinical coordinator position in Boston due to my sig. other moving up to work out of Fort Devens. Currently i work in Fla as an assistant nurse manager of a smaller nicu. I was a CNII at level 3 NICU's for the past 6 years so my expirience with bedside nursing is strong. In this past year, even though titled assistant, i have been more of the manager of my unit due to our small unit being absorbed under L&D's manager (budget effective). I have done a fair amount in the past year that has made some very strong administrative skills. I am originally from NJ, so Im very used to the personalities and know i will never have it as good as here in fla, but so is life. I have never worked in a union hospital though, and would appreciate some advice on what it is like from the management perspective. What is the pay like for unit managers, how hard is it to deal with the specific regulations unions set forth? Anything would be helpful... if it is that hard and more lucrative to stay as a bedside nurse do my 3 12's then that would be fine with me also. I really do love my job as a NICU nurse, but have made a lot of professional growth in my new position. Thanks in advance for any insight!
