How to Deal With Difficult Coworkers

It’s 9:40 on a Tuesday. The meeting started ten minutes ago and you’ve already been interrupted twice, your idea from last week has just been presented by someone else as theirs, and there’s a message from your manager asking for “a quick update” on something you updated yesterday. Nobody has raised their voice. Nothing dramatic has happened. And yet by lunchtime you’re more tired than if you’d run a marathon.

Most of what makes work hard isn’t the work. It’s the people. Not monsters, usually, just people doing things that make your day harder, often without seeming to notice.

This guide is about those people: why they behave the way they do, and what you can actually do about it. It won’t turn a difficult colleague into a friend. But understanding what drives someone usually changes how much of their behavior lands on you, and that alone makes Monday mornings lighter.

Why some coworkers are difficult

It helps to start with an uncomfortable idea: almost nobody thinks of themselves as the difficult one. The colleague who never answers a direct question thinks they’re being careful. The one who corrects everyone thinks they’re keeping standards high. The one who says “fine” in a tone that clearly means “not fine” thinks they’re being polite.

That’s not because they’re lying to themselves on purpose. It’s because we all judge our own behavior by our intentions and other people’s by its effects. Psychologists have a name for the second half of that habit, the fundamental attribution error: when someone else does something irritating, we blame their character; when we do it, we blame the situation. We look at this habit in more detail in Why Do People Behave the Way They Do?.

Once you allow for that, most difficult behavior at work comes from a short list of drivers.

Pressure. People under pressure narrow. They stop noticing how they come across, they cut corners in conversations, and they push their stress onto whoever is closest. A colleague who is abrupt with you in a deadline week may be perfectly pleasant in a calm one.

Insecurity. A lot of controlling, credit-taking and point-scoring behavior comes from people who feel their position is fragile. If you believe you could be found out or replaced at any moment, every meeting becomes a place to prove your worth, sometimes at someone else’s expense.

Status and territory. Workplaces are full of small hierarchies: who decides, who gets copied on emails, whose project gets the budget. People defend their patch, and a surprising amount of friction is really an argument about territory dressed up as an argument about process.

Avoidance of conflict. Many people never learned to disagree directly. So disagreement leaks out in other ways: a late reply, a sarcastic comment, a “per my last email”, a quiet word with someone else instead of with you.

Habit and culture. Some behavior is simply learned. Someone who spent ten years in a team where you had to fight for airtime will keep interrupting long after they’ve left it. Some offices reward gossip, some reward being seen to work late, some reward never admitting a mistake.

None of this excuses anything. But it changes the question you ask. Instead of “why are they doing this to me?”, which has no useful answer, you can ask “what is this behavior doing for them?”, which often does.

The behaviors that wear people down most

Difficult coworkers come in many shapes, but a handful of behaviors account for most of the stress people describe. Each of them has its own guide on this site; here is the short version.

Passive aggression

The colleague who agrees in the meeting and then doesn’t do it. The email that is perfectly polite and somehow insulting. The “no worries!” that clearly means worries. Passive aggression is anger that someone doesn’t feel allowed to express openly, so it comes out sideways. The way through is usually to make the indirect thing direct, calmly and without accusation.

Gossip

Gossip has a bad name, but most of it is harmless: people swapping information about who is doing what. It turns toxic when it becomes a way to build alliances, punish people who aren’t in the room or spread stories that can’t be checked. Understanding why people gossip makes it much easier to decide when to listen, when to change the subject and when to step out. See Why Do People Gossip at Work?.

Micromanagement

A manager who checks everything, rewrites your emails and wants to be copied on every decision is exhausting. It is almost always about the manager’s anxiety, not your competence, and that’s actually good news, because anxiety can be reduced in ways that incompetence can’t. See Why Do Some Bosses Micromanage?.

Bullying

Bullying is different from ordinary friction. It is repeated, it is targeted, and it is meant to diminish. It needs a different response: documentation, allies and, often, formal channels. We look at what drives it and how to protect yourself in Why Do People Bully?.

Interrupting

Some people interrupt because they’re excited, some because they’re anxious about losing their thought, and some because they want control of the conversation. Each type responds to a different approach. See Why Do People Interrupt?.

A simple way to respond to almost any difficult behavior

Different behaviors need different handling, but there is a basic approach that works surprisingly often. It has four steps.

1. Separate the behavior from the person

“Mark is impossible” leaves you nowhere to go. “Mark replies to my emails with questions he could answer himself” gives you something to work on. Describing the specific behavior, as precisely as you would describe a bug in a piece of software, takes some of the heat out of it and points you toward a response.

2. Guess at the need behind it

Ask yourself what the behavior gets the other person. Reassurance? Control? Recognition? Safety from blame? You won’t always guess right, but even a rough guess changes your tone. It’s hard to be furious with someone you suspect is frightened.

3. Say one clear, calm sentence

Most difficult behavior survives because nobody names it. Naming it doesn’t need to be a confrontation. A single sentence, said in a normal voice, often does more than a long conversation:

• “I’d like to finish my point, and then I want to hear yours.”
• “I noticed the report went out without the changes we agreed. Can we check what happened?”
• “I’d rather hear that from you directly, if something’s bothering you.”
• “I can have this to you by Thursday. If you need daily updates, let’s agree a format so you don’t have to chase.”

Keep it short, specific and about the future. The aim is not to win the argument about what happened. It’s to change what happens next.

4. Protect your work, your time and your record

When a behavior repeats, write it down: dates, what was said, who was there. Not to build a case for war, but because memory is unreliable under stress and patterns are easier to address than incidents. Copy yourself on important agreements. Put decisions in writing. These small habits are boring, and they are what protects you if things escalate.

What not to do

A few reactions feel good in the moment and almost always make things worse.

Matching their behavior. Answering passive aggression with sarcasm, or gossip with counter-gossip, gives the other person a new grievance and puts you in the same mud.

Venting to everyone. It’s healthy to talk to one or two trusted people. Telling the whole floor turns a problem with one person into a reputation problem for you.

Waiting for them to change on their own. They might. But most people don’t change behavior that is working for them, and if nobody ever names it, from where they sit it’s working.

Assuming the worst every time. Once you’ve labeled someone as difficult, you’ll start reading everything they do through that label. Some of what annoys you will be perfectly innocent. Keep checking.

When to involve your manager or HR

Most friction with coworkers is best handled directly, between the two of you. But there are situations where you shouldn’t carry it alone:

• The behavior is repeated and targeted at you, or at a particular group.
• It involves harassment, discrimination, threats or anything that may break the law or company policy.
• You’ve tried to address it directly and it has continued or got worse.
• It’s affecting your health, your sleep or your ability to do your job.

When you do raise it, bring the record you’ve kept. Describe behaviors and their effects, not personalities. “On these four occasions, my work was presented in meetings without credit, and I was not invited to the follow-up” is much harder to dismiss than “she’s a credit thief.”

Looking after yourself

Working alongside someone difficult takes a quiet, steady toll. A few things help more than they seem to.

Keep the problem in proportion. One difficult colleague is one person, not your whole job. Make a point of noticing the people at work who are easy to deal with, and spend a little more time with them.

Leave it at work when you can. Replaying a meeting at dinner gives the other person your evening as well as your day. A simple rule helps more than it should: write the problem down once before you leave, with the one thing you’ll do about it tomorrow, and don’t reopen it at home.

And keep an honest eye on your own part. Not because it’s your fault, but because it’s the part you control. Sometimes the most effective change in a difficult working relationship is a small change in how you respond.
