The warning signs often appear in how someone handles accountability, attention, pressure, and power.
Ever worked with someone who always needs to be right, admired, or in control? That person may be displaying narcissistic tendencies—and over time, those tendencies can quietly sabotage your workplace.
Narcissistic traits are not always obvious at first. People with strong narcissistic tendencies often come across as confident, charismatic, persuasive, and highly capable. They know what to say, how to impress the right people, and how to project competence. The problems usually surface gradually. To be clear: you cannot diagnose a coworker or boss with narcissistic personality disorder. That requires a qualified mental-health professional. What you *can* do is notice repeated patterns of behavior that erode trust, damage relationships, and lower team morale.
Here are five warning signs worth watching.
1. Everything revolves around their needs
Someone with strong narcissistic tendencies often struggles to see beyond their own priorities, status, recognition, or needs.
If you’re a peer or leader, notice what happens when your interests conflict with theirs. Do they listen? Show curiosity about your perspective? Compromise? Or does every conversation eventually circle back to what *they* want?
One selfish moment means little. A consistent pattern means a great deal.
2. Pressure brings out their worst behavior
The real test of character appears when things go wrong. Missed deadlines, customer complaints, or failed projects reveal more than success ever does.
Healthy leaders may feel stressed, yet they continue to communicate, stay engaged, and help the team solve the problem. Leaders with strong narcissistic tendencies often become defensive, angry, distant, controlling, or preoccupied with protecting their image.
Pressure exposes what confidence sometimes conceals.
3. They deflect accountability
One of the clearest red flags is an inability to say:
- “I was wrong.”
- “I handled that poorly.”
- “That’s on me.”
Instead, responsibility is redirected. Someone else misunderstood. The employee failed to execute. The instructions weren’t clear. The process is broken. Conversations end with them defending themselves rather than owning the outcome.
When someone consistently explains away their own behavior while holding everyone else accountable, pay close attention.
4. Their treatment of you shifts based on what they need
One day you’re brilliant. The next day you’re barely acknowledged.
You may receive praise, attention, and encouragement when you are useful to them—followed by withdrawal, criticism, or indifference when you are not. This inconsistency leaves colleagues constantly trying to predict which version of the person will appear. Over time, people begin adjusting their own behavior simply to avoid triggering a negative reaction.
5. They are skilled at managing impressions
Some people with narcissistic tendencies are remarkably persuasive. They know how to charm, flatter, and tell senior leaders exactly what they want to hear.
That is why the most reliable way to evaluate someone is not to listen only to what they say, but to watch what they repeatedly *do*. Do they follow through? Keep commitments? Share credit? Character becomes far clearer when you stop focusing on promises and start tracking patterns.
What to Do If You Work With Someone Like This
Resist the urge to get drawn into emotional battles. You are unlikely to change someone’s personality through repeated confrontation, and arguing about motives rarely helps.
Focus on observable behavior instead. Set clear boundaries. Keep important communication in writing. Document decisions, assignments, deadlines, and agreements.
If the behavior becomes abusive, retaliatory, discriminatory, or otherwise serious, escalate through the appropriate channels—typically HR or higher leadership.
Most importantly, stop trying to earn approval that continually moves out of reach.
The larger leadership lesson is this:
Don’t judge people only by how they treat those above them. Watch carefully how they treat people who can do nothing for them.
Charisma and self-confidence can create a strong first impression. True character reveals itself over time.
