As Suzanne noted, agencies will happily sign you up and throw you to the wolves -- they are interested in their profits, not your professional growth and development (or any risks to your license). Facilities pay agencies a lot
of $$$ for nurses, and, for the amount of money they're shelling out, they are expecting to get a seasoned pro who can walk in and do the job with minimal orientation.
Do you feel that you are competent to walk into an unfamiliar setting and practice nursing independently, with little or no orientation and little or no assistance or supevision? Also, it's not uncommon that the facilities that are willing to pay the big bucks for agency personnel have
to do so because working conditions are so bad that they can't keep permanent staff ... There are a number of recent threads about bad experiences that people have had with agencies (local and traveling); you may want to search and review them before you make a decision.
Best wishes for whatever you decide.
