Happened to me, too. I found out that my whole team hated me, actually. I didn't notice and thought I would just reasonably argue my position(s). I have to add that I was working in Zürich in Switzerland (as a German) and my reputation got destroyed, so I had a problem finding a new job until I found one, where they did not check my past employer (as described in the article). This was unintentional and it can happen quicker than you think. The last rule of the Old Hacker "to stop insisting you are right after 2 attempts, even if you are sure you are" hints into the direction that this is a general problem for software engineers rather than just/only a personal flaw - But ofc I will work on and watch out for my "Leumund" much better and more carefully in the future. Also that he was affected: Excluded from decision making meetings. I am not sure, if he knows/understand how bad it might have been for(against) him.

It all still bites you/yourself.

Good luck in your job search!
