So I just got my annual PPD redone and I sent the results to the travel company I am starting with in October. The agency is now telling me that I have to take another PPD so that it's within one month of my start date... Has anyone ever heard of this ?! I thought PPD's were an annual thing? Why would I need to get one in August and then another in September?

So I have just signed my first travel nursing assignment... Yay! But the only bad thing about it, is that the hospital that I will be working for has told me that they will be doing all my scheduling themselves. Aka "filling me in the gaps where needed." I will also be working night shift, so working shifts that aren't in a row is going to be horrible for me. Has as anyone else encountered this in travel nursing? I was under the assumption that I signed myself up for the days I was available through my agency and those were the dates the hospital got my help. I feel like maybe I'm being taken advantage of since I'm new and I am unaware of how this all works. Let me know your all's thoughts! (:
