The image is formatted in a tweet with image format. The caption says "handle with care" over two pictures. The first picture is of an Amazon package with "fragile" written in sharpie. The second picture is on the inside the box with a paper and the text "a middle manager's ego" on it.
I'm not going to blame this on insecurity, but I think ego is a bit more accurate. I was working under a senior software engineer in maybe his 50's in my first real job out of college. A big part of our time went to maintaining a build system that was fairly large, maybe on the order of tens of thousands of lines of Ant code.
The bone that I have to pick looking back is that I got the blame when I had trouble organizing myself. Our team didn't use any sort of issue tracker. There was absolutely zero collaboration tools beyond verbally issued instructions in meetings and email. Looking back, I realize it was madness. As an experienced developer, my manager should have had known that an issue tracker would be a high priority. Yet instead I was blamed.
Wait how did you even get anything done haha
Well, I didn't get much done. I relied some on internal organization with Emacs org-mode to keep track of things. I didn't know this at the time, but that particular position had a high turnover rate. Apparently a year was pretty typical, which was how long I lasted. I have never outright quarreled with any other manager except this one.
