advice from any nurses out there

Im a nurse and I'm contemplating on doing local traveling assignments,however I'm concerned. Reason being is that i left without giving two weeks notice to a previous employer(hospital) which is a large corporation and i know they listed me as non- rehire im afraid that the travel agency could send me on a possible assignment to a hospital within that corporation and they refuse me because I was listed in the system as a non rehire. Is this a possibility and is there any advice you could give me?
