The Coworker You Can't Stand
The Scene. There's one in almost every office. The one who takes credit in the meeting, replies-all to correct your typo, sighs theatrically at your ideas, or simply grates on you in a way you can't quite name. You've started rehearsing arguments in the shower. You dread the calendar invite with their name on it. And the worst part: you can't fire them, and neither can you quit over it.
The Voice. Marcus Aurelius ran the Roman Empire, which means he managed difficult people at a scale you will never have to. His trick was to see them coming. In his private notebook — the Meditations, book two — he braced himself each morning (George Long's public-domain translation): "Begin the morning by saying to thyself, I shall meet with the busy-body, the ungrateful, arrogant, deceitful, envious, unsocial." He wasn't being bitter. He was pre-loading his patience, so that difficult people cost him no surprise and no peace.
The Method. You can't change the coworker. You can change the system around the friction. Here's the well-established playbook:
Separate the person from the behavior. "He's insufferable" gives you nothing to act on. "He interrupts me in meetings" does. Name the specific behavior and its concrete effect on your work — that's the only thing worth addressing.
Audit your own share first. Are you snubbing back, going cold, cc'ing their boss? Fix your half before you raise theirs; it also protects you if this escalates.
Address it directly, in private, early. Use a plain, non-accusing script: "When X happens, the effect is Y. Can we do Z instead?" Private and specific de-escalates; public and vague inflames.
Reduce the surface area. If talking doesn't land, engineer less contact and more clarity — agendas, written decisions, defined ownership. Move volatile exchanges to channels with a paper trail.
Document the pattern. If the behavior is genuinely disruptive — sabotage, credit-theft, hostility — keep dated, factual notes: what happened, when, who saw it. Facts, not feelings.
Escalate through the right door. When it's affecting the work and self-help has failed, bring the documented pattern to your manager or HR. Frame it around business impact ("this is slowing the project"), not personal dislike.
Protect the relationship you actually need. You don't have to like them. You have to be able to work with them. Aim for functional, not friendly.
And when none of it changes them — as often it won't — fall back on the emperor's real point: their character is theirs to carry, and your calm is yours to keep.
Marcus met the arrogant and the ungrateful before breakfast, on purpose. Expect the friction, and it stops running your day.
