Early in my career, a manager once had me repeat to him that I would be terminated if I failed to do X, like I was a 5-year-old.

X was referring to a technical implementation detail that he had zero understanding of. He read something in a blog post I guess.

My reaction was to act like it was a fun joke or something. But inside, I absolutely loathed him every second of every day until I quit, and now I take great satisfaction knowing that I’ve surpassed him and would never do a thing to help his stagnating career. (In other words, I’m holding an extremely petty and lasting grudge.)

But my point is, he probably thought I was fine with all his joking. I always laughed.

To expand on the article’s point, I think the biggest thing young managers don’t understand is that people are going to be insincere to you as a basic showing of respect and a basic desire for career preservation. They’re going to smile and appear to enjoy you and laugh at your jokes and seem ok with everything, much moreso than they otherwise would. So don’t make the mistake of using their reactions to define your boundaries of what’s acceptable or what’s funny, because it’s not a typical relationship, and you will invariably believe that you are funnier than you are and that a wider range of unacceptable behaviors are acceptable.
