My immediate supervisor was a dude who was best friends with the department manager, which is why he had his job. I know this because they had the same working relationship at their previous bank, and bragged about it. Anyways, my supervisor fancied himself a programmer, which he was not.
I was saddled with existing Perl code and it was my job to fix it and enhance it during the course of the day. I did my job well. Apparently, my supervisor would get bored late at night, and would wade through my code and reformat it and re-comment it to suit his own style tastes. No functional changes, just comment styles and formatting. And broke the code in the process. Every night.
Every morning I came in and there were people waiting for me wanting to know why the software was broken. Nothing I said to my supervisor or the department manager made any difference. I fixed the same stuff over, and over, and over.
And all my co-workers knew was that my software was always broken.
