An OHN? What kinds of jobs are out there?

I've decided to apply for an NP program with a specialty on Occupational Health. I have not much exposure to this field, but I'm interested in having that as my specialty. I was wondering what kind of jobs are out there for an Occupational Health Nurse with an NP degree/certificate. Also, what state do you practice? Is it true that it's hard to find a job as an OHN? I'm from California, what will my future be like here as a future OHN? Thanks!
