How to Deal with a Mean Coworker without Losing Your Cool

Have you ever felt your chest tighten after a meeting with that colleague? People can fuel joy, laughter, and momentum. They can also trigger stress, frustration, and real pain. Many of my clients come to me because they are struggling with someone at work who feels mean: dismissive comments, a cutting tone, interruptions mid-sentence, microaggressions, or quiet undermining that slowly chips away at confidence.

These moments can make you feel undermined, ashamed, and angry.

When we feel those things, our brain goes straight into protection mode.

It wants to defend us, often by assuming the worst about the other person.

If you have ever thought:

• “He doesn’t think I’m capable.”
• “She is treating me differently because I’m a woman.”
• “He is trying to make me look bad.”
• “They just don’t respect me.”

You are not alone. These thoughts are normal. They come from a desire to stay safe. But reacting from that place without slowing down often leaves us more hurt, more frustrated, and with less power to change things.

Below is the process I guide clients through to regain emotional ground, stay effective, and teach others how to treat them.

This approach does not excuse bad behavior.

It gives you the power to respond with clarity, not fear or anger.

Step 1: Separate What Actually Happened From the Story in Your Head

When clients first describe a situation, it often sounds like this:

• “He is just a mean person.”
• “She thinks I am useless.”
• “He talks down to me because I am new.”
• “She is undermining me.”

These interpretations make sense, but they are interpretations, not facts.

To get clarity, I always ask:

“What did they literally say and do, word for word?”

This part is uncomfortable, because when you strip away the meaning your brain created, the situation often sounds different.

Example 1

• You: “We have this problem.”
• Them: “What is your plan?”
• Your brain may say: “He thinks I do not have a plan. He does not trust me. He is doubting my capability.”

Example 2

• You: begin sharing an idea.
• Them, interrupting: “I do not think that is the right direction.”
• Your brain may say: “He did not even hear me. He does not respect me. He does not value my voice.”

I get it. The tone, timing, and body language matter. They often trigger emotional meaning and old experiences.

But by pulling apart 1) what was literally said and 2)what I interpreted that to mean, you create space to think clearly.

Most clients already feel calmer here, because the nervous system is no longer driving the moment.

Step 2: Possible Reasons That Have Nothing To Do With Me

The next step is to consider reasons that are not about you.

This does not mean excusing the behavior. It means removing a filter so you can see more possibilities.

Ask:

“What are other reasons someone might act this way that have nothing to do with me?”

For example:

• They are under pressure about the project.
• They think they are being efficient or “doing their job.”
• They do not realize it comes off harsh.
• They were taught this is “strong leadership.”

Before this step, many clients are sure the person has a bad intention toward them.

After this step, at least the possibility exists that the behavior is not about them. This is huge. You can put down your guard, stop being defensive, and choose a response that serves you.

This step is not about giving people excuses.

It is about considering all possibilities so you can regain your power.

Step 3: Inform With Curiosity

Now you can face what actually happened.

Name what they did. Name how it made you feel. Then get curious about what they are worried about or trying to solve.

Use two parts:

1. describe the observable behavior and your feeling

2. ask a curious question to understand the real concern

Example 1: “When you asked for my plan right away, I felt like you did not trust my ability to handle it. What are your real concerns here?”

Example 2: “When you interrupted me mid-sentence and changed the topic, I felt ignored and ashamed. What made you think that approach was not the right answer?”

In this way, they know what they did, which is a fact, and how it made you feel, which is your experience. Many people do not know how their behavior lands. Often they say they did not realize and that it was not their intention.

By asking questions with the intention to understand and support, they may open up about their real concern. You can then help address it. This is the beginning of a new relationship.

Step 4: Teach Them How To Treat You

If they simply did not know their behavior hurt you, share how you want to be treated. This is not an order. It is guidance. They can choose to do it or not, but at least they know your standard.

Example 1: “Next time, when you have a concern, I would appreciate it if you share the concern directly instead of asking whether I have a plan.”

Example 2: “Next time, if you think my idea is not aligned with your direction, please explain why so I can understand and come back with a better idea. I want our team to be successful.”

Healthy boundaries look like this. Clear. Respectful. Actionable.

Emergency: Make a Plan

In rare situations, you may not know how to respond in the moment.

Once, a new business partner I had never met got angry and yelled at me in our first meeting. He claimed I was lying and not doing my job. I knew he had a misunderstanding and I tried to explain, but he was not in a state to hear me. I kept trying to resolve it and it was emotionally exhausting. I was shaking and it took a few days to calm down.

After that, I made a plan. You can make your own plan too.

The plan is simple. Decide a phrase you will use. Practice it. Then use it to create time and space.

It can be short: “Ouch. That hurts.”

Or a little longer: “I cannot talk to someone who is yelling. Let us talk again when things are calm.”

Then walk away if needed. This buys you time to think about what you want to do next. It is okay to walk away from a situation that feels threatening to you.

Knowing your phrase in advance gives your nervous system something to hold onto when you need it most.

Final Thought

When someone’s words or tone hurt, your nervous system jumps in to protect you with assumptions, stories, judgment, and armor. That does not make you weak. It makes you human.

This four-step process helps you:

• regain emotional control
• see the situation clearly
• protect yourself without shrinking
• invite healthier behavior
• maintain your leadership presence

You deserve to be spoken to with respect.

You can advocate for that with clarity and courage. Real strength is not reacting the fastest. Real strength is choosing your response with intention.

Boundaries That Protect Your Energy and Power

We often hear about “setting boundaries,” but the phrase can sound vague or even harsh. What does it really mean? A boundary is the line you cannot allow others to cross.

It is not about small preferences or things you would rather avoid. A boundary protects what you need to feel safe, respected, and whole.

Boundaries are also an invitation for others to meet you with respect.

Why Boundaries Are Essential

When you do not hold your boundaries, you may find yourself giving until nothing is left, or drained because you never refill your own energy. When you do hold them, you protect your wholeness, and from that place you can show up more powerfully for yourself and others.

Boundaries are not optional niceties. They are the foundation for sustainable leadership, meaningful relationships, and personal well-being.

For you, boundaries:

• Protect your core values and rights
• Preserve energy to show up at your best
• Prevent you from carrying obligations that are not yours
• Build confidence by proving you matter
• Ensure you are respected as a person, not only as a role

For others, boundaries:

• Create clarity so they do not have to guess
• Build trust through consistency
• Help relationships thrive instead of eroding under tension

Boundaries are not a “no” to others. They are a “yes” to what really matters.

👉 Reflection: Why are boundaries important to you?

The Many Shapes of Boundaries

When people hear the word boundary, they often picture a rigid rule like, “Do not call me after 9 PM.” But boundaries are not about arbitrary limits on a clock. They are about respect. Respect for your time, your energy, your values, and the space you need to thrive.

Boundaries take many forms in everyday life:

• Time – How you spend your hours and when you are truly available
• Energy – What restores you, what drains you, and how you protect the balance
• Emotional – How you allow yourself to be spoken to or treated
• Physical – Your body and your personal space, including what touch or closeness feels safe
• Responsibility – What is yours to carry and what is not
• Values – The principles you will not compromise, no matter the circumstance

Each of these areas gives you a different way to draw the line and claim the space you need. Some boundaries will be visible and clear, like telling a colleague when you are not available. Others are quieter, like choosing not to take on someone else’s emotional burden or saying no to work that goes against your values.

When I work with women leaders, the most common struggles show up in time and responsibility. Too often, they say yes too quickly, or take on what was never theirs to begin with. Over time, this leaves them exhausted and frustrated, with little left for what actually matters.

👉 Reflection: Which type of boundary feels most important for you right now?

Healthy Boundaries vs. Walls

A common hesitation is: “If I set boundaries, will I come across as cold, selfish, or difficult?” The truth is the opposite. Healthy boundaries are not about shutting people out. They are about letting people in, in a way that honors both you and them.

Think of it this way:

• A wall says: Stay out. I will not let you in. It is rigid, isolating, and built on fear or hurt.
• A boundary says: Here is how you can come closer while respecting me. It creates safety, clarity, and trust.

Boundaries are not barriers to connection. They are pathways to better connection. When you hold them, you are not rejecting others. You are inviting them to meet you where trust, respect, and authenticity can grow.

Healthy boundaries also signal to others that you value yourself. And when you model that, you give them permission to value themselves too. That is why boundaries do not just protect relationships, they strengthen them.

👉 Reflection: With one person in your life, how would things change if you set a boundary instead of a wall?

Spotting Where You Need Boundaries

Understanding boundaries in theory is good, but the real question is how you recognize when one is missing or when an existing one needs refinement. Often your body and emotions will alert you before your mind catches up. Pay attention to these signals. They are like warning lights on your dashboard.

Some of the most common ones are:

• The “yes, but” moment: you say yes on the outside, but inside you feel a heavy no.
• The “have to” moment: you feel trapped in something you never chose, weighed down by obligations that are not yours.
• Lingering irritation: small requests or interactions leave you disproportionately drained or resentful.
• Deep exhaustion: not healthy tiredness after effort, but depletion from overextension.

These signals are not inconveniences, they are clues that your guardrail is missing or too low. When ignored, they can build into resentment, burnout, or even a sense of losing yourself.

The good news is that every signal is also an invitation. Instead of pushing through, you can pause and ask: What boundary do I need here? What line would protect my energy, my values, or my well-being?

👉 Reflection: When did you last feel pushed past your limits?

How to Set a Boundary

Once you notice the signals, the next step is to define and express the boundary you need. A boundary is never about rules for their own sake. It is about honoring what matters most to you, your time, your values, your peace of mind.

When you frame boundaries this way, they stop feeling like restrictions and start becoming affirmations of what you need to thrive. For example, instead of thinking “Don’t call me after 9 PM,” the deeper boundary is “I want my personal time to be respected.”

The clearer you are about what you are protecting, the easier it becomes to express it. You can then choose simple, calm language to share it, not as an attack or demand, but as a statement of respect for yourself.

Examples:

• “Evenings are my time to recharge, so I don’t respond to work emails after dinner.”
• “I protect my peace, so I leave conversations where there is yelling.”

Notice how each one points back to a principle: respect for time, peace, or role. The phrasing matters less than the clarity of what you are honoring.

👉 Action Step: What principle do you most want to protect, and how can you express it in one boundary statement?

Closing Thought

Boundaries are not about shutting people out. They are about keeping yourself whole. Strengthen just one boundary this week and notice how your energy and confidence shift.
