do i want to be an occupational health NP w master in public health?

i am in a RN to masters program at USF and I need to choose a masters course of study. They offer a program that gives you a masters in public health and an occupational health adult NP. I am very interested in this program but I am having trouble finding info on the career itself. The program is pretty long and I am concerned if it is worth it. according to the info that I have found on occupational health nurses I wont be making any more money than I am making now. But that info also seems to apply to ADN and BSN nurses and does not seem to include MSN nurses nor the Public health degree. Does anyone know what type of position that this will land me and what salary it will demand.
