What part of NC? I live in North Eastern NC. I would expect no less than $20 an hour to start. I have heard of nowhere that offers less than that round these parts...
The only exception to that rule may be a MD's office. Some LTC Facilities in this area offer weekend option above $30 an hour no matter your experence. However someone on weekends must die for you to get that spot. I have only worked at one LTC Facility in this area and it is by far the worst. Offered me $19 an hour prn. I did that long enough for orientation to be over and for me to secure a hospital prn spot to supplement my weekend option pay. If its what you want to do.. Great. If not atleast its a job. If they try to lowball and won't come up on there offer, work long enough for the experence and to pay bills but keep looking. Continue to send out applications. Also, one thing I learned as a overbearing arrogant new nurse is don't burn any bridges. Finally, its also nice to keep your foot in the door some where else also. Just in case.
