Re-orientation?

I have a concern that I need help with. I just went back to my old L&D job after a two year break. Before then I had 1 1/2 years experience in L&D. When I left, I left the hospital scene completely and did not have anymore experience with ivs, 2wfs, etc. Well, I decided to go back and I did the interview with the new nurse manager. When I was in the hospital orientation on the second day (it is usually 4-5 days), the nurse manager called me up and wanted me to start on the floor the next day. I asked her would I be with someone since I have not had the experience in awhile and she said yes. The next day she was not working and no one knew what I was suppose to be doing. I paged her and left a message but when she called back she did not speak to me not even when the other nurse told her I called. I was told by the CN to go back downstairs for the hosp orientation. Well the NM did come in that day and I spoke with her (I went back to the unit to get my things and she was there). She said that she did not know that I was going to need the "full orientation" and for me to get back with her for she had to update the orientation manual. Well the day I was to report back, she still wasn't there. I precepted with a nurse but I checked the schedule and I was scratched off the next day and not on there for any other days. The next day I asked the CN bcause the NM was still not there if I could come in the next few days. I was told "Well we thought that you were going to be able to pick up where you left off so the chief nurse wants to talk to you"
Am I wrong for wanting to have some sort of re-orientation to the unit after a break? I know that in the real world you sink or swim but I feel that in l&d time is of the essence. The unit has been remodeled and the hospital had document changes and everything. I expected a rough time on the unit bcause they have had a huge turnover in the past months-year. Almost all of the nurses I worked with left (most have been there for 5+ years). From what I heard from a good many it was "management issues". Well now I am waiting for the Chief to clock in so I can call her. I kind of know what to expect. I went back to l&d because I missed it but now I don't want to be there. I just hate to keep job hopping. I guess that I am still trying to find me.
What would you do?
