You do not need to like everyone you work with.
You do need a way to work when the relationship is difficult.
Maybe they interrupt constantly.
Take credit.
Miss deadlines.
Send hostile messages.
Ignore requests.
Create drama.
Or simply make every ordinary task harder than it needs to be.
The first mistake is often turning a behaviour problem into a personality diagnosis.
"They are toxic."
"They are impossible."
Those labels may express how frustrated you feel.
They rarely tell you what to do next.
Focus on what happened.
Use:
Behaviour. Impact. Boundary. Record. Escalate.
Name the behaviour
Replace:
"James is impossible."
With:
"James agreed to provide the figures Tuesday and has missed the deadline three weeks in a row without warning."
Now you have something you can address.
Specific behaviour creates specific options.
Personality labels create arguments.
Separate irritation from interference
Not everything annoying requires intervention.
Someone talks loudly.
Uses too many emojis.
Has a different working style.
Likes meetings more than you do.
That may be irritating.
A different category is behaviour that affects your ability to work, deadlines, quality, credit, professional treatment or safety.
Save your energy for what materially matters.
Address the issue early
Minor problems often become major stories because nobody says anything.
Try a calm, direct conversation.
"When the figures arrive after Tuesday, I lose the time I need to finish the client report. Can we agree that if Tuesday is going to slip, you let me know by Monday afternoon?"
Notice what is missing.
No character judgment.
No history lesson.
No "you always."
Just behaviour, impact and request.
Create a boundary
If the problem repeats, the boundary may need to become clearer.
For example:
"I am happy to discuss disagreements, but I do not want to continue the conversation while we are speaking to each other like this. Let's come back to it at 3pm."
Or:
"I can review the deck if it arrives by 2pm. After that I will not have enough time to turn comments before tomorrow."
A boundary describes what you will or will not do.
It does not require controlling the other person's personality.
Keep records when the pattern matters
Documentation is not the answer to every workplace disagreement.
But when a repeated behaviour affects delivery, credit, conduct or escalation, contemporaneous records can be useful.
Keep dates, agreed actions, missed commitments, relevant messages and the effect on the work.
Write facts.
Not:
"James was being ridiculous again."
Write:
"14 August: agreed figures by 12pm. Received 4:45pm after two follow-ups. Client report moved to next morning."
If you later need help, facts are easier for another person to assess.
Avoid the gossip trap
A difficult coworker can become an addictive topic.
You start telling one colleague.
Then another.
Soon half the office has a version of the story.
You may be right about the original problem and still damage your own reputation through the way you handle it.
Talk to people who can actually help.
Your manager.
A relevant project lead.
HR where appropriate.
A trusted adviser outside the immediate situation.
Do not turn frustration into a campaign.
Protect your credit quietly
If someone regularly takes credit for shared work, increase clarity around ownership.
Use project updates.
"Sarah completed the client interviews, James built the model and I developed the recommendation and final presentation."
Or send progress notes that naturally document contribution.
You do not need to accuse someone publicly.
Make ownership visible.
Escalate the work problem
If direct conversation has failed and the behaviour is affecting delivery, raise the operating problem.
For example:
"I have tried to resolve the handoff directly with James, but we have missed the agreed input deadline on four of the last five cycles. It is now affecting the client delivery. Could we agree a different process?"
This is stronger than:
"James is a nightmare."
The first statement allows your manager to act.
Serious behaviour is different
Not every workplace problem should be handled with another communication framework.
Harassment, discrimination, threats, bullying, retaliation, serious misconduct or safety concerns may require formal workplace processes or professional advice.
Use the policies and support available in your organisation and jurisdiction.

Take the difficult person out of the sentence.
Write:
The behaviour is:
The impact is:
The request or boundary is:
If it continues, the next appropriate step is:
You may discover that the situation is more manageable once the problem has a shape.
What to remember
Deal with behaviour before personality.
Use:
Behaviour. Impact. Boundary. Record. Escalate.
You cannot control whether another person becomes easier.
You can become clearer about what you will do next.
