At some point in your career, you will work closely with someone you genuinely cannot stand. Not just a personality mismatch — someone whose communication style, work ethic, attitude, or behavior makes every interaction feel like a tax. And unlike a bad date or a difficult neighbor, you can’t simply avoid them.

How you handle that relationship will say more about your professional maturity than almost anything else — and it will directly affect your results, your reputation, and your peace of mind.

First: Separate the Problem From the Person

Before you decide how to handle it, get specific about what’s actually bothering you. “I don’t like them” isn’t actionable. The following are:

• They interrupt me in meetings and don’t acknowledge my input
• They consistently miss deadlines that affect my work
• Their communication is dismissive or condescending
• They take credit for shared work
• Their negativity affects the team’s energy

Naming the specific behavior — not the person’s character — is what makes it possible to address. It also helps you figure out whether this is a professional conflict, a values mismatch, or just a personality difference you need to manage.

Adjust Your Expectations — Not Your Standards

One of the most useful reframes for working with a difficult colleague is recognizing that you cannot change them. You can only change how you engage.

That means adjusting your expectations of who they are — not lowering your standards for the work. If someone is consistently late on deliverables, stop depending on them for last-minute input. Build their delay into your timeline. If someone is negative in meetings, stop expecting enthusiasm and start planning around it.

This isn’t resignation — it’s strategy. You’re removing the friction that comes from repeatedly being surprised by predictable behavior.

Communicate Directly — Once

If the behavior is affecting your work output or your ability to do your job, it’s worth addressing directly — once, clearly, and without escalation in the first instance. Research from Harvard Business Review consistently shows that direct, private conversations resolve workplace conflict more effectively than triangulation or avoidance.

Keep it specific and forward-looking: “When the deliverables come in after the deadline, it creates a bottleneck on my end. Can we agree on a buffer time going forward?”

You’re not attacking their character. You’re solving a shared problem.

Find the Overlap — However Small

You don’t have to like someone to work well with them. But you do need to find at least one point of genuine alignment — a shared goal, a mutual standard, a project outcome you both care about.

This is especially important in long-term working relationships. People who find common professional ground, even with people they personally dislike, consistently outperform those who rely on interpersonal warmth to collaborate, according to organizational psychology research from the Journal of Applied Psychology.

Ask yourself: what does this person actually care about at work? Start there.

Manage Your Own Reactions

The person who controls their reaction in a difficult dynamic almost always has more power than the person who doesn’t. That means:

• Not venting about them to mutual colleagues — it creates alliances and escalates tension
• Not matching their energy in meetings — if they’re dismissive, stay measured
• Not letting their behavior define your performance — your output is yours regardless of the dynamic

This takes genuine discipline. But the alternative — letting a difficult colleague affect your quality of work or your professional reputation — is far more costly.

Keep a Record If It Escalates

If the behavior crosses into harassment, consistent undermining, or conduct that’s affecting your ability to do your job, document it. Dates, specific incidents, impact on work. This isn’t about building a case immediately — it’s about having clarity if you need to escalate.

Escalation to a manager or HR should come after direct communication has failed and the behavior is ongoing. Go in with specifics, not complaints.

Know When to Disengage Strategically

Sometimes the most professional move is minimizing contact. If the relationship is genuinely toxic and irreparable, reduce collaboration to the functional minimum. Keep interactions task-focused, written where possible, and brief. You don’t owe anyone a warm relationship at work — you owe them professionalism.

And if the situation is serious enough that it’s affecting your health or career trajectory, that’s a signal worth taking seriously. Tolerating a damaging dynamic indefinitely is not toughness — it’s a cost you shouldn’t have to absorb alone.

The Bigger Picture

Working with people you don’t like is a skill, and like every skill it improves with practice. The women who navigate these dynamics best aren’t the ones who never encounter difficult colleagues — they’re the ones who’ve developed a clear framework for engaging without losing themselves in the process.

Professional doesn’t mean warm. It means consistent, capable, and controlled — regardless of who’s in the room.
