Have you looked into how many new graduate nurses ate struggling to find a job?? There are numerous threads on here regarding that. Unfortunately, you may run into not being able to get a job, much less worrying about low pay. (nurses aren't rolling in money the first year out of school, they are often paid the bare minimum because that's how desperate the situation has gotten in some states)
Just think about the career move seriously. You'll be acquiring more debt and may be unable to find a job for months or years depending on your region and how saturated the market is with nurses.
As a Social Worker, you can wok in Case Management in the hospital as well. I know many who chose this route in Georgia, Florida, and Louisiana who only had a BSW. They see a lot of stuff an are actually able to help people get the treatments and assistance they need at their discharge.
Good luck I hope someone else is able to give you some insight as well. If I had known how bad it would be, even though I will be a BSN graduate, I would have gone with Surgical Tech or Respiratory Therapy or Radiology. Those fields seem to be hurting more in my area.
