Our hospital policy is for RN's to keep seniority when changing departments. After 15 years in the ED I accepted a position in Interventional Radiology. It wasn't until 8 months of being there, (when it was time to bid on vacations and holidays based on seniority) was I told I am at the bottom of the seniority list. There are only eight of us nurses and I would be second from the top. I brought it up to my manager who said she would "look into it" but of course did nothing. What would you do? Do I push the subject and really upset my co-workers in a small department? Or do I just deal with it and be happy I got the job?
