To Bay Area Dialysis Nurse

I requested a transfer to a Da Vita chronic dialysis in San Fran. bay area. I have 10 years experience in Hemodialysis as an RN. I was offered 33/hr working 12 hour shifts and of course, the time and a half pay after 8 hours so basiacally working 12 hours for $490. Does this sound about right. Seems like they are not offering much higher for experinced dialysis nurses as I was told by the manager they hire RN's without experience and start them with $31/hr. Seems unfair don't you think?
thankss
