Two day orientation only

I have been working on a rehab unit licensed as a SNF for the past 6 months. It is within a hospital network and being that I have worked two years in an LTACH and did a very short stint in a trauma ICU, I really wanted to get more into acute care again, really wanting to do trauma. I accepted a position in a med/surg trauma unit in the hospital network (with my manager's blessing) and started about a week ago, feeling it would be a good place to learn more about trauma and develop my skills again. When I got there, I discovered I was only being given a 2 day orientation. I admitted I felt a bit out of practice being that I hadn't done telemetry, assessments, drips, etc... in about a year and would feel better with more time. The unit manager agreed with me as well. I requested about a month just to get up to speed. I was told today I could not have a month of orientation and it was suggested that I go back to my previous unit for now and that my previous unit would like me back. They also suggested I speak with the recruiters to see if there is an acute care unit with lower acuity so I can refresh my skills. I am of course returning to my precious unit for the time being that I am grateful the network does value me as a nurse and it is a job, however this is not necessarily what I want and I feel I will continue to lose my skills here.

Is two days of orientation the norm for experienced nurses? I feel like I'm going to be stuck in SNF nursing forever. And I actually got at least a 3 month orientation at the SNF, which I did not need at all. I'm really quite frustrated. I went to this new unit to learn and it didn't seem to happen.
