This is compounded by many managers not understanding the details of what their direct reports actually do. I've had so many supervisors in my career who just have no concept of what I really do in IT, though it's pretty obvious to me and my coworkers. So when it comes to review time, I'm always having to walk them through what I actually do.

Contrast this to when I am tasked with creating a report that they need. They're amazed. Absolutely amazed that I can write something coherent. I can only assume that with the Peter Principle, they're all surrounded by idiots who write emails and reports like Epstein.
