Ego management is also about not stepping on someone else's ego, and not taking offense when it doesn't make sense to.
At the place I worked, I saw how others were set up by certain people. It was a culture I didn't buy into. Like they kept on trying to tempt me to join in.
This poor guy that I worked with (I'm almost certain he was on the spectrum) had a day off and what my "colleagues" did was disgraceful. I will preface this by saying, he was a bit hippy-ish, but I never detected a problem with his level of hygiene, personal or otherwise (unlike some other members of staff!). The guys I worked with started spraying his desk and chair etc with disinfectant and saying horrible things and laughing while they did it.
I just internally shook my head and got on with my admin work.
They would often plot together in front of me about what they were going to do to stitch this guy up. There was no doubt in my mind that if their overt behaviour towards me was similar to their overt behaviour towards him, there was a good chance they were doing similar things to me.
I also confirmed this when I was carrying a bit too much to unlock the office door. I could hear them talking about someone, lots of crude names being used and what they were going to do to this person. I managed to juggle the things I was carrying and opened the door and entered to see them all looking a bit pensive but still talking about this person and how the manager wanted something to "use against" them in "the meeting on Tuesday".
I assumed to begin with that is was (I'm referring to him as) David that they were plotting to ambush. They even told me it was. Only one slight problem, David left that evening. I was helping him put something in his car, and I said "So we'll be seeing you again on Tuesday right?", To which he said "No, I'm leaving tonight, like right now." I could see one of my colleagues looking a bit worried. So I just said "Oh I thought you had some sort of debriefing on Tuesday?"
It turns out I had a meeting on Tuesday though.
