By the numbers

How much a manager shapes work and wellbeing.

Managers matter

70%of the difference in employee engagement between teams can be traced to the manager, at least (Gallup).
55% vs 10%of U.S. workers unhappy vs happy with their manager relationship described their work experience as toxic (APA, 2025).
81% vs 54%of workers happy vs unhappy with their manager relationship rated their mental health as good or excellent (APA, 2025).

Bullying bosses

65%of people who bullied others at work were bosses (Workplace Bullying Institute survey, 2021).
30%of U.S. workers said they had been bullied at work (WBI, 2021).
19%of U.S. workers said their workplace was very or somewhat toxic (APA, 2023).

What makes a boss toxic?

Tough, imperfect or harmful? How to tell the difference.

Most bosses have bad days, and many are simply not great at managing. A toxic boss is different. The harm is a pattern, it keeps happening, and it leaves you feeling small, scared or worn down.

Researchers use the term “abusive supervision”. It means a boss showing hostile behaviour, in words or in other ways, over and over, not counting physical contact.

Humiliating staff, making unrealistic or unethical demands and playing favourites are all signs of abusive leadership.

📏 Demanding but fairHigh standards, clear reasons, respect.

A good boss can still push hard, give tough feedback and say no. The difference is respect: expectations are clear, feedback is about the work, and you are treated as a person.

🫤 Just not a good managerDisorganised or unclear, but not cruel.
Read more

Some bosses are distracted, forgetful or poor at planning. That can be frustrating and stressful, but it is not the same as being targeted. Clear questions and written follow-ups often help here.

The “Work & mental health” guide has a section on difficult coworkers and tricky managers.
☣️ ToxicA pattern of harm that leaves you shaken.
Read more

It may be toxic if your boss often

  • Blames you for their mistakes
  • Humiliates or yells at people, especially in front of others
  • Makes unrealistic or unethical demands, like unpaid overtime
  • Plays favourites, giving chances to some and not others
  • Uses threats about your job to control you

One psychologist describes a toxic workplace as more of a feeling than a checklist. Your body often knows first.

If you keep doubting yourself (“Maybe I’m too sensitive”), that is common. Writing things down can help you see the pattern more clearly.

Common toxic boss patterns

Ways a harmful boss can show up. Tap any card.

Toxic bosses don’t all look the same. Naming the pattern can help you stop blaming yourself and choose a response. These are common descriptions, not labels for diagnosing anyone.

😡 The yellerOutbursts, sarcasm and public put-downs.
Read more

Anger that explodes without warning keeps everyone on edge. People start tiptoeing and hiding mistakes, which makes work harder for everyone.

What can help

  • Stay calm and keep your voice level
  • Say you’ll pick it up when things are calmer: “I want to fix this. Can we talk at 3?”
  • Write down what happened, word for word if you can
🔬 The micromanagerChecks everything, trusts nothing.
Read more

Constant checking can leave you feeling you have little control. Low control over your work is one of the WHO’s listed risks to mental health at work.

What can help

  • Offer regular updates before they ask
  • Agree what “done” looks like at the start
  • Ask for one area where you can work more independently
🏆 The credit-takerTakes the praise, hands out the blame.
Read more

Having your work claimed by someone else can feel deeply unfair. Fairness at work is closely linked to mental health.

What can help

  • Share progress in group emails or team channels
  • Keep your own record of what you did and when
  • Build relationships with other leaders who see your work
🌀 The unpredictable oneWarm one day, cold the next.
Read more

Not knowing which version of your boss will show up can keep your stress system switched on. You may find yourself reading their mood all day.

Try to focus on what you can control: your work, your responses and your support outside work.

👻 The absent bossNever available, then angry when things go wrong.
Read more

Unclear roles and no guidance are risks to mental health at work too. When a boss is never there, you may be blamed for decisions you had to make alone.

What can help

  • Send short written summaries: “Unless I hear otherwise, I’ll go ahead with…”
  • Ask for a regular 15-minute check-in
  • Ask who to go to when they aren’t available
🧲 The boundary-crosserLate-night messages, personal questions, guilt trips.
Read more

A boss who expects you to be always available, or pries into your personal life, can make it hard to rest. In 2025, about 1 in 4 workers without a disability, and over 4 in 10 with one, said their employer did not respect their personal boundaries.

The “Setting boundaries & saying no” guide has scripts you can adapt for work.
🪞 The gaslighter“That never happened.” “You’re overreacting.”
Read more

Some bosses deny things they said, rewrite events or make you doubt your memory. Over time, this can shake your confidence in your own judgment.

Written records and a trusted person to check in with can help you stay anchored in what really happened.

The “Emotional abuse & gaslighting” guide explains this pattern in more depth.

How a toxic boss affects you

Mind, body, home life and confidence.

A harmful boss doesn’t just make work unpleasant. Research links abusive supervision with more distress, emotional exhaustion, lower wellbeing and people quitting their jobs.

The link can reach your body too. In a Swedish study that followed more than 3,000 men for about 10 years, those who rated their managers’ leadership more highly had a lower risk of heart disease. The link grew stronger the longer they had worked for that manager.

🧠 In your mindDread, self-doubt, replaying conversations.
Read more

You may notice

  • Doubting skills you used to feel sure of
  • Dread on Sunday evenings or before shifts
  • Feeling anxious or low
  • Replaying what your boss said, over and over
💪 In your bodyStress shows up physically.
Read more

You may notice

  • Headaches or a tight jaw
  • Poor sleep
  • Stomach upsets
  • Tiredness that rest doesn’t fix

Job stress can keep your body’s stress system switched on day after day, which can affect sleep, mood and physical health over time.

🏠 At homeWork stress rarely stays at work.
Read more

You may be short with family, too drained to see friends, or spend evenings talking about your boss. That is a sign of how heavy it is, not a personal failing.

Feeling this way does not mean you are weak. It is a normal human reaction to being treated badly by someone with power over you.

Protecting yourself day to day

Ways to stay steady while you decide what to do.

You can’t control how your boss behaves. But you can control how you respond, and how you care for yourself around it.

🧊 Stay calm in the momentDon’t match their heat.
Read more

Taking a breath and letting the first wave of feeling pass helps you stay steady. A neutral, non-defensive tone can calm things down.

Phrases to buy time

  • “Let me look into that and get back to you.”
  • “I hear that you’re frustrated. What would you like me to do next?”
  • “Can we talk about this in private?”
🪨 It’s about them, not your worthTheir behaviour says more about them.
Read more

Try not to take harsh treatment personally. A boss’s behaviour may come from their own stress, pressure or habits. Understanding that doesn’t make it okay, but it can loosen its grip on your self-worth.

🔋 Refill outside workYour life is bigger than this job.
Read more

Ideas

  • Time with people who know and value you
  • Movement, sleep and regular meals
  • Hobbies that have nothing to do with work
  • A “no boss talk” rule for part of each evening
⏸️ Short resets at workSmall breaks to calm your body.
Read more

Taking short mental health breaks during the day can help you cope in a stressful workplace.

Slow belly breathing can help you feel calmer: breathe in gently through your nose and out slowly through your mouth.

Talking to your boss

When it feels safe, a calm, clear conversation can help.

Sometimes a boss doesn’t realise how they come across. If you feel safe doing so, a calm conversation about one specific thing can make a difference. Speaking up assertively means being kind, clear, calm and fair.

A simple way to raise it

  1. Ask for a private moment at a calm time.
  2. Describe one specific event, not their character: “In Tuesday’s meeting, when…”
  3. Say how it affected the work: “It made it hard for me to share updates.”
  4. Ask for what you need: “Could we talk about feedback one-to-one?”
  5. Follow up with a short, friendly email summary.
If your boss is threatening, harassing or punishing you, you don’t have to confront them alone. Going to HR, a union rep or a trusted senior leader may be safer.
The “Plan a talk with my boss” worksheet helps you prepare. The “Speaking up & assertiveness” guide has more practice ideas.

Keeping records & going to HR

Writing it down, and taking it further.

If it keeps happening, short, dated notes are one of the most useful things you can keep. They help you see the pattern, and they help others understand it if you report it.

📝 What to write downFacts, not feelings, for the record.
Read more

For each event

  • Date, time and place
  • What was said or done, as exactly as you can
  • Who else was there
  • Any emails, messages or documents
  • How it affected your work or health

Keep notes somewhere private that you control, not only on a work computer.

🏢 Going to HR or a senior leaderStick to facts and ask for what you need.
Read more

Follow your company’s process for raising concerns. Stick to facts: no blaming, just stating what happened.

Things to ask

  • What happens next, and when will I hear back?
  • How will my report be kept confidential?
  • What protection is there from retaliation?
  • Can I move teams or report to someone else while this is looked at?
🪧 Unions and worker groupsYou don’t have to go in alone.
Read more

If you have a union, a representative can support you in meetings. In the U.S., most private-sector workers have the right to act together with coworkers to improve working conditions, with or without a union.

When it crosses legal lines

Harassment, discrimination and retaliation (U.S. basics).

This is general information, not legal advice. Being a mean boss is not always illegal. But some behaviour is against the law, and employers have special responsibility for harassment by supervisors.

🛑 Harassment and discriminationLinked to who you are.
Read more

Federal law covers harassment based on race, colour, religion, sex (including pregnancy, sexual orientation and transgender status), national origin, age 40 or older, disability or genetic information, when it is severe or pervasive or becomes a condition of keeping your job.

An employer is automatically responsible for supervisor harassment that leads to a negative job action, like firing or demotion.

🔁 RetaliationPunishment for speaking up is illegal.
Read more

It is illegal to punish workers for raising concerns about discrimination or harassment, taking part in an investigation, or asking for a disability accommodation.

⏳ Deadlines matterUsually 180 or 300 days.
Read more

In general, a charge must be filed with the EEOC within 180 calendar days, or 300 days where a state or local agency enforces a similar law. Federal employees have 45 days to contact an EEO counselor.

The EEOC can be reached at 1-800-669-4000 (TTY 1-800-669-6820) or eeoc.gov.

The “Workplace bullying & harassment” and “Your rights at work” guides explain your rights in more depth.

Stay, transfer or leave?

Weighing your options with a clear head.

If things don’t improve, it is okay to look at other roles, inside or outside the company. Leaving a harmful job is not quitting on yourself. Sometimes it is the healthiest choice you can make.

🔄 Moving teamsA new boss without a new employer.
Read more

An internal move can keep your pay, benefits and history while getting you away from the harm. Look at open roles, talk to people in other teams, and ask HR how transfers work.

🧳 Planning an exitLeave on your terms, when you can.
Read more

Things to think about

  • Savings or income to cover a gap
  • Health coverage between jobs
  • References from people other than your boss
  • Updating your CV or résumé quietly, a little at a time
The “Job loss & job hunting” guide covers job searching, and the “Should I stay or go?” worksheet in “Work & mental health” helps you weigh it up.
⏱️ If you need to stay for nowSurvive it while you plan.
Read more

Money, visas, health coverage or family needs can make leaving hard. Staying for now is not a failure. Focus on protecting your health, keeping records and building your support while you plan your next step.

How community helps

Allies at work and people outside it.

A harmful boss can make you feel isolated, especially if others seem afraid to speak up. Building relationships with supportive coworkers, and leaning on people outside work, helps you cope.

👥 A gut check from a coworkerSomeone who sees it too.
Read more

A trusted coworker can give you a reality check and may have noticed the same pattern. It can be a huge relief to hear: “It’s not just you.”

🧑‍🏫 Mentors and other leadersPeople who can offer perspective.
Read more

A mentor inside or outside your company can help you think through options, practise conversations and remind you of your strengths.

🤲 If you see a coworker targetedSmall actions help.

Ideas

  • Check in privately afterwards: “That looked rough. Are you okay?”
  • Offer to be a witness if they report it
  • Don’t join in the gossip or blame
  • Share where to find support, like the EAP
If you manage people, the “Mentally healthy workplaces” guide explains what good managers do.

When and where to get help

Signs it’s time to reach out, and where to turn.

It is a good idea to talk to a professional if stress or low mood lasts two weeks or more, or gets in the way of your work or home life.

Where to start

  • A therapist or counselor, to work through stress, confidence and next steps
  • Your primary care provider, especially if stress is affecting your body or sleep
  • Your workplace Employee Assistance Program (EAP), free and confidential
  • The EEOC, a lawyer, legal aid or your union for legal questions
Outside the U.S.? Workplace laws differ, so check your national labour agency. Free, confidential helplines in many countries are listed at findahelpline.com.
If you face violence or threats at work, get to a safe place and call 911. If you feel hopeless or are thinking about suicide, call or text 988 (U.S.), or text HOME to 741741.
