A difficult coworker can make a good job miserable. You can't control how they behave, but you can control your response, your professionalism, and your paper trail. Keep the high ground and it usually works in your favour.

First, manage yourself

  • Stay professional even when they don't — it protects your reputation.
  • Don't get pulled into gossip or drama; it makes you look part of the problem.
  • Depersonalise it where you can — difficult people are usually like that with everyone.

Address it directly (once)

If it's affecting your work, a calm one-to-one often helps. Use an “I” statement and stick to specifics:

“When feedback comes in front of the team like that, it's hard for me to act on it. Could we do those one-to-one?”

Escalate the right way

  • Document specific incidents — dates, what happened, impact.
  • If it continues or crosses a line, raise it with your manager or HR with those facts.
  • Frame it around work impact, not personal dislike.

Common mistakes that make it worse

Most people don't lose these situations because the other person is difficult. They lose because they hand the difficult person ammunition. A few traps that reliably backfire:

  • Venting to the wrong people. Complaining to shared colleagues feels good for five minutes and then travels straight back to the person you're complaining about. Vent to someone outside the team, or not at all.
  • Matching their tone. If they're passive-aggressive in email and you fire back sarcasm, you've just made yourself look as bad as them. Stay flat and factual. Boring is a weapon.
  • Collecting grievances silently. Saying nothing for six months then dumping everything at once reads as an ambush, and half of it will be too old to act on.
  • Going in to win. If your goal is to get them in trouble rather than to fix the working relationship, managers can smell it, and it costs you credibility.

The 24-hour rule

When something lands badly, draft your reply, then don't send it for a day. Nine times out of ten you'll soften it, and the softer version is the one that actually works.

Match the tactic to the type

"Difficult" isn't one thing, and the same fix doesn't work on all of them. Read which one you're dealing with, then respond in kind:

  • The credit-taker. Put your work on the record before they can. Send a short update to the group, cc the relevant people, and name who did what. Visibility beats resentment.
  • The blocker who never replies. Move from chat to email with a clear deadline: "I'll assume you're happy for me to proceed unless I hear back by Thursday." Then proceed.
  • The undermine-in-meetings type. Don't defend on the spot. Ask a calm clarifying question — "What would you do differently?" — and make them own the criticism in front of everyone.
  • The mood-bomb. Keep contact short, specific and transactional. Don't try to fix their mood; just protect your own time from it.

How to know it's working (and when to stop trying)

Don't expect them to change into a friend. A working relationship is a low bar on purpose. It's going in the right direction if replies come faster, meetings get less tense, and you stop rehearsing conversations in the shower. Give a direct approach four to six weeks before you judge it. If nothing shifts, or things get worse after you raise them, that's your signal to stop absorbing it and escalate with your paper trail. Protecting your own sanity and reputation is the win here, not fixing them. If it's genuinely affecting your health or your standing, that's not a personality clash any more, and it's worth a quiet chat with HR about your options.

Frequently asked questions

Should I confront a difficult coworker or just ignore them?
Ignore the small stuff that costs you nothing. Address anything that affects your work, your reputation, or repeats. The middle ground of silently seething is the worst option: it changes nothing and slowly wrecks your mood. If it matters, say it once, calmly and specifically. If it doesn't, genuinely let it go rather than keeping a private scoreboard.
What if the difficult coworker is my boss?
The playbook is similar but the paper trail matters more. Confirm decisions and requests in writing, keep tone neutral, and never criticise them to the team. If it's serious, go up a level or to HR, but frame it around business impact and specifics, not personality. Line up another job option too; leverage changes how these conversations go.
How do I stay professional when they've genuinely made me angry?
Buy time. "Let me come back to you on that" is a complete sentence. Step away, write the angry version somewhere you'll never send it, then respond to the facts only a few hours later. Anger read as fact by others makes you look like the problem, so protect the record even when they don't deserve the restraint.
Is it worth going to HR about a difficult coworker?
HR is worth it when there's a pattern, evidence, and real impact on your work or wellbeing, less so for a one-off clash. Remember HR protects the company, not you, so bring dates, examples and what you've already tried. Frame it as wanting a workable solution. Keep your own copies of everything you share.
