HR vs Manager

I interviewed in one of the hospitals in my area and the manager and I clicked right away that she offered me the position during the interview. After the interview, HR sent me a list of paperwork I had to complete. They hire third party companies to do all these paperwork. Apparently one of the document they wanted me to submit got left out, and they didn't submit it to the HR of my hospital. HR called me and told me I had to submit all of it or else I won't be able to start. I explained to her that I already submitted them and I don't understand why they don't have it. She gave an attitude and threatened me that she won't let me start and implied in taking back the offer. I understand that she need all of those and I didn't say I won't submit them but I was just trying to explain my side. Now I'm worried. Should I tell the manager about this? Can she actually take back an offer?
No, don't tell the manager. Why would you want to include her in a problem that sounds like it could be easily solved, before you even begin? Unless your offer is in writing it can easily be rescinded. Play nice with HR and get the paper they want done...Pronto.

I agree to not get the manager involved. As annoying as hr is. Just get the paperwork bak sooner then later. Good luck !!
