Part of Manipulation Tactics: Signs, Examples & Guides
It might be the manager who rewrites yesterday's instructions and then blames you for following them. Or the colleague who takes credit in meetings, praises you in private and undermines you in public. Or the director whose mood decides how the whole team's week goes. Work adds complications that personal relationships do not: you cannot always leave, a lot of the power may sit with the other person, and your livelihood is involved. This guide describes what people mean when they talk about a narcissist at work, the behaviors that tend to cause the most harm, and practical ways to protect yourself, your record and your health.

What people mean by "a narcissist at work"
The phrase is shorthand for a colleague, manager or leader whose behavior seems driven by a need for admiration and control and a lack of concern for others. It is not a diagnosis. Mayo Clinic describes narcissistic personality disorder as a mental health condition, and only a qualified professional can assess it. You cannot diagnose a boss or a coworker, and you do not need to. A difficult person at work can be harming you whether or not there is a clinical label.
What you can do is look at the behavior, at its effect, and at what your workplace's own standards say about it. The World Health Organization's fact sheet on mental health at work lists several risks to mental health in the workplace, which it also calls psychosocial risks. They include violence, harassment or bullying, discrimination and exclusion, limited support from colleagues, authoritarian supervision, and an organizational culture that enables negative behaviours. In other words, the conditions that make a difficult person at work especially damaging are recognized as workplace issues, not simply personal ones.
Behaviors people describe
None of these proves anything on its own. Many bosses and colleagues have bad days, and a single incident is not a pattern. What matters is repetition and the effect on you.
Several of these overlap with the tactics in our overview of 14 manipulation tactics. At work they often take a specific form because of reporting lines, performance reviews and reputation.
Why work makes it harder
The power is uneven
If the person controls your assignments, reviews, pay or references, it is harder to push back, and the risks of doing so are real. That is why documentation and outside advice matter more here than in many other situations.
It can be hard to name
Many of the behaviors are deniable and look like management: "high standards", "direct feedback", "a demanding culture". If everyone around you accepts it, you may start to wonder whether the problem is you.
Exclusion hurts
Being frozen out is more than unpleasant. A 2021 meta-analysis of 95 independent samples (N = 26,767) found that exposure to workplace ostracism was significantly related to employees' attitudes, wellbeing and behaviors; the authors describe workplace ostracism as rampant in organizations and as regarded as a kind of "social death". Psychologist Kipling Williams's review of research on ostracism describes being ignored or excluded as a signal of threat to which pain and distress is a reflexive response, and notes that prolonged ostracism can deplete coping resources. If you are being ignored or left out of loops on purpose, your reaction is a normal one. See also the silent treatment.
Your career is entangled
Leaving can mean losing income, references, visa status or a career you built. The decision to stay or go is yours and may take time. You can protect yourself in either case.
What it can sound like
"I never told you to send it to the client. You should have checked with me. I'm disappointed in your judgment."
"Thanks to everyone for their input. I developed the approach, and the team helped with the details."
"You're one of my best people. It's a shame you struggle so much with this kind of thing."
"Between us, Priya says you've been dragging the project down. I'm only telling you because I want you to succeed."
"Let's not waste everyone's time. Does anyone else want to explain what this is supposed to mean?"
Some of these could be a clumsy moment from a stressed manager. What makes them part of a pattern is how often they recur and which direction they push: toward you doubting yourself and relying on the person for approval.
A difficult person at work can be harming you whether or not there is a clinical label.
First steps
1. Stay steady and professional
It is tempting to respond in kind, vent to colleagues or send an angry email. Slow down. Anything you write may be forwarded, and the aim is to make your own conduct unimpeachable.
2. Create a paper trail
You are not being paranoid. Keeping a record is standard practice when a work relationship is difficult.
- Keep dated notes of incidents, what was said, who was present and the effect on your work. Write them soon afterwards, and keep them somewhere private, such as a personal device or notebook, not on a work system.
- Confirm verbal instructions in writing. After a conversation, send a short email: "Thanks for the chat today. To confirm, you asked me to prepare X by Friday and to send it to Y. Let me know if I've misunderstood."
- Save key communications such as praise, instructions and deadlines, following your organization's rules on data. Do not copy confidential material you are not entitled to.
- Record facts, not feelings. "On 12 March in the team meeting, my manager said X" is stronger than "he was awful".
The National Domestic Violence Hotline notes that documenting abuse in personal relationships can help people process complex emotions and serve as evidence if necessary. The same logic holds at work: a calm, dated record is more credible, and often more useful to you, than memory.
3. Protect your credit
If someone tends to take credit, make your work visible in a neutral way: send summaries to relevant people, copy your manager's manager when appropriate, present your own results where you can, and say "As I mentioned in my email of Tuesday…" in meetings.
4. Keep communication clear and brief
Where you need to deal with the person directly, our guide to the grey rock method shows how to keep exchanges short, factual and professional. At work, that often means communicating in writing, sticking to the task and not reacting to provocations.
5. Do not join the games
Avoid venting about the person to colleagues, passing on their remarks or taking sides. It can feel like solidarity, but it often gets repeated and can be used against you. Choose one or two trusted people, ideally outside the person's circle of influence, to talk to.
Setting boundaries
Boundaries at work are about your time, your scope and how you are treated. A few examples:
- Scope: "I can take this on if we move X to next week. Which would you like me to prioritize?"
- After-hours contact: "I'm offline after six. I'll pick this up first thing tomorrow."
- Tone: "I want to get this right. Can we go through the specifics without raising our voices?"
- Public criticism: "I'm happy to discuss this, but I'd prefer to do it after the meeting."
- Information: "Could you send that in writing so I'm sure I've got the details?"
These are not magic. A person who dislikes limits may push back. But they establish a record of reasonable requests, and they signal what you will accept without escalating.

When to escalate
Informal approaches do not always work, and sometimes the pattern is serious enough to need official channels. Consider escalating when:
- the behavior is repeated and affecting your work or health
- there is harassment, discrimination or threats
- you have tried to address it directly and it has continued or worsened
- you are being excluded from work you are entitled to do
- your records show a clear pattern
How to approach it
- Read your organization's policies. Look for anti-bullying, harassment, grievance and whistleblowing policies, and find out the process and timelines.
- Talk to someone independent first. A union or employee representative, an employee assistance program or a trusted mentor can explain how the process works in practice.
- Prepare a concise summary. A one- or two-page timeline with dates, facts and effects is more useful than a long narrative.
- Describe behavior and impact. Avoid diagnostic labels such as "narcissist". They are easy to dismiss and can make a complaint look personal.
- Ask for what you want. A change of reporting line, a mediated conversation, a formal investigation, a written commitment on conduct.
- Keep copies. Store your own records safely and outside work systems.
What to expect
Processes vary a great deal. Some organizations take complaints seriously and act; others do not. There can be a risk of retaliation, even where it is prohibited, and outcomes are not guaranteed. In many places there are legal protections and outside bodies you can consult, and the rules differ by country and by type of complaint. This article does not give legal advice. If the stakes are high, consider speaking to a qualified employment lawyer or an organization that advises workers before you act.
Looking after yourself
Working under someone who undermines you affects more than your mood. People describe trouble sleeping, dread on Sunday evenings, trouble concentrating and a loss of confidence.
- Keep routines outside work. Sleep, exercise, friends and interests give you somewhere to stand that does not depend on your job.
- Name what is happening. Having words for it can reduce the self-blame. The WHO's list of risks to mental health at work is a reminder that these are recognized workplace problems.
- Talk to someone. A friend, a counselor, an employee assistance service or your doctor. In the UK, the NHS provides an overview of mental health treatments, including talking therapies.
- Set limits on rumination. Writing things down, then closing the notebook, can help you stop replaying conversations all evening.
- Seek help if you are struggling. If you are having thoughts of harming yourself, contact a doctor, a crisis line or emergency services.
Staying or leaving
There is no right answer, and the decision may change over time.
If you stay
Decide what you need: a transfer, a change of manager, clearer boundaries, or simply to get through a project. Keep your record up to date, build allies and keep your options open by maintaining your network and your skills.
If you leave
Prepare calmly where you can. Keep your records, think about references, and consider what you will say about why you are leaving. You do not need to explain every detail. A neutral line such as "I'm looking for a role that's a better fit" is enough.
If you cannot leave yet
Many people stay for good reasons: money, visas, family responsibilities, an uncertain market. You can reduce the impact in the meantime with documentation, boundaries, allies and care for your health. Staying does not mean you accept the behavior.
It is one perspective, it can be wrong, and it does not diagnose anyone.
If you manage or work alongside the person
If you are a manager or colleague who sees this, you have power too. Listening without taking sides, checking facts directly with the person concerned, and not repeating what you hear about people all help. If someone brings you a concern, take notes, ask what they need and point them to the process. The Hotline's guidance for supporters in personal situations, to avoid judging people's decisions and to remember that you cannot rescue them, applies reasonably well at work too.
If you recognize some of this in yourself
Everyone can be defensive, take credit unfairly or snap under pressure. If colleagues seem afraid to disagree with you, or you find you often feel under attack, it is worth asking for feedback from someone you trust and considering coaching or therapy. Noticing is a good sign.

Frequently asked questions
How do I know if my boss is a narcissist?
You cannot know, and you do not need to. Nobody can diagnose someone from the outside. What matters is the behavior, its pattern and its effect on you and your work, which you can document and address whatever the cause.
Should I confront a coworker who takes credit for my work?
Often it works better to make your work visible than to confront. Send summaries, copy relevant people and say what you did in meetings. If the behavior continues, a calm private conversation, framed around specifics, can help. Keep a record of what happens.
Should I tell HR?
It depends on your organization and your situation. Before you do, read the relevant policies, talk to someone independent such as an employee representative, and prepare a factual timeline. Be aware that processes vary and that retaliation can occur even where it is prohibited. If the stakes are high, consider getting advice first.
Is being ignored at work really that harmful?
Research suggests yes. A meta-analysis of 95 samples found that workplace ostracism was significantly related to employees' attitudes, wellbeing and behaviors. Being excluded on purpose is a recognized problem, not oversensitivity.
What if no one believes me?
A record helps. Facts with dates are harder to dismiss than impressions. Talk to someone outside the team, such as an employee representative or a mentor, and consider a professional such as a counselor or an employment adviser.
Can I use the grey rock method at work?
Yes, in the sense of keeping exchanges brief, factual and professional, and not reacting to provocations. If the behavior amounts to bullying or harassment, grey rock is not a substitute for the complaint process.
