The distinguishing feature of this problem is proportion. Something about this one person occupies a share of your attention that their actual impact on your work does not justify. You have replayed a comment from Tuesday. You notice their name in a channel before you notice anything else in it. Meanwhile, colleagues who are objectively worse at their jobs cost you nothing at all.
That gap between impact and irritation is the thing to look at, because it is where the useful information is.
What is usually going on
They break a rule you keep. You do not interrupt, and they interrupt. You do not send work out until it is right, and they send drafts. You would never claim a team result in the first person, and they do it in every update. What stings is not the behaviour; it is that the behaviour is working for them while your restraint goes unremarked. Almost nobody experiences this as envy, because it does not feel like wanting what they have. It feels like an unfairness.
You are on opposite ends of an ordinary trait. Someone two standard deviations from you on conscientiousness or extraversion is not doing anything wrong and is going to grate constantly. The thorough person reads the fast one as careless; the fast one reads the thorough one as a bottleneck. Both are describing a real difference and both have attached a motive to it that is not there.
They have power over something you need and no obligation to you. Peers who control a dependency — the review, the approval, the data — produce a specific kind of irritation that is really about exposure. You cannot escalate, you cannot compel, and you have to be pleasant about it. That is a structural problem wearing a personality problem's clothes.
They remind you of someone. Unfashionable to say and frequently true. A tone of voice, a way of dismissing things, a particular smile. If the intensity of the reaction was there in week one, before they had done anything, this is worth considering honestly, because the colleague is then carrying a charge they did not earn.
They are genuinely behaving badly and you have been talked out of noticing. The opposite failure. Workplaces are good at reframing a real problem as a personality clash, and people who are conflict-averse accept the reframe quickly. If two other colleagues independently avoid the same person, your irritation is data about them, not about you.
What to do about it
- Name the specific behaviour in one sentence, with no adjectives. They answer questions addressed to me in meetings. If you cannot get it to one sentence, the reaction is currently bigger than the thing, and the sentence is what shrinks it.
- Ask whether you would mind if someone you liked did it. A surprisingly reliable test. If the answer is no, you have a relationship problem rather than a behaviour problem, and those get worse with silence and better with one ordinary conversation.
- Reduce the surface. Fewer shared meetings, asynchronous updates instead of live ones, a dependency routed through someone else. Distance solves more of this than insight does, and there is no prize for working through it.
- Say the one sentence to them, once, plainly, and near the event rather than six weeks later. Most of these never get raised at all, which is why they last for years.
- Check whether the irritation is arriving on top of an empty tank. Tolerance for ordinary colleagues is one of the first things exhaustion takes, and a rested person often finds the same behaviour merely mildly annoying.
What it depends on
Whether this is about them, about you, or about a gap between two ordinary positions is the question, and trait scores answer it faster than reflection does. Conscientiousness, extraversion and agreeableness are the three that produce nearly all office friction, and the reason the friction feels moral is that traits are experienced from inside as standards — the careful person does not think of themselves as high on a dimension, they think of themselves as someone who does the job properly. Seeing both positions as percentiles removes the moral frame without pretending the difference is not real, and the entry on traits covers why those positions are so stable that waiting for a colleague to change is a poor plan.
