I work in a corporate advisory. Two months ago we were working on a project/documentation. My reporting manager and her intern prepared the said document, the intern left and the client made a request to add the information from the document we had prepared from scratch to the document they provided us.
As the intern left, the Reporting manager assured me that she has checked the entire document line by line and all I have to do is incorporate our document into the document provided by the client. That is exactly what I did.
However, the client has been feuding with us with respect to some clause in the document that we had added. As per the client we have a dded a wrong clause.
The Reporting manager has been very subtly trying to shift the blame of the fuck up on me.
Kindly note that my company's HR is a puppet who would do nothing even if I report it to them.
What do I do. This is my first job btw.
