IA to Quality Control

We do not have an Internal Audit Charter. There are two of us in the department. I would like to draft a charter and submit for approval. However, it appears as if they would like to make one of us quality control. This I believe is so that we (one of us) is able to make corrections and findings are not necessarily reported to the Audit Committee. Can senior management change one of us from IA to Quality Control? Thanks in advance.
