The internal audit department is a career ender. If you do as your told by IA management, no other IA department that will hire you as you will have demonstrated a lack of understanding of the function of an internal auditor. I've heard this from several large organizations. As IA you are expected to seek out control issues to improve the company, bring the issues to Compliance/CFO/CEO and the board, and be transparent with external auditors, clients, regulators, etc. IA management does not endorse these actions.
