How to Set Boundaries with an Overbearing Colleague

Colleague boundary issues are some of the most uncomfortable to navigate because you share a workspace and can't simply stop seeing this person. A calm, direct conversation that focuses on the behavior (not the person) almost always works better than letting resentment build.

Original Message

You keep interrupting me and getting involved in my work when I didn't ask for your help.

Hi [Name],

I wanted to find a moment to chat — or I can share this in writing if it's easier.

I've noticed that [specific behavior] has been affecting my ability to concentrate and work through things independently. I want to raise it because I think we work well together, and I don't want this to become a problem.

Would you be open to [proposed change — checking in at a set time, reaching out by message first, giving me space to complete a first draft before offering feedback]?

Thanks for hearing me out,
[Your Name]

Polite Version

Hi [Name],

I hope you're well. I wanted to mention something — a bit awkward to bring up, but I'd rather say something than let it fester.

I've been finding [specific behavior] a bit disruptive lately. I know it's not intentional, but it does affect my focus. Do you think we could try [proposed change]?

Thanks so much for understanding,
[Your Name]

Firm Version

Hi [Name],

I need to address something directly. [Specific behavior] has been affecting my work, and I need it to stop.

Going forward, please [specific request]. I'd prefer to resolve this between us rather than escalate it.

Regards,
[Your Name]

When to Use This Template

  • When a colleague frequently interrupts your focused work time
  • When unsolicited feedback or involvement in your projects has become disruptive
  • When a colleague's behavior is affecting your wellbeing or output
  • When you want to address the issue before it requires HR involvement

Common Mistakes to Avoid

Using 'you always' or 'you never' language: Absolute statements put people on the defensive. Be specific about what you've observed.
Raising it publicly or in a group setting: This kind of conversation needs privacy.
Not being specific about what you're asking them to change: 'Please give me more space' is vague. 'Could you check in with me at noon rather than throughout the day?' is actionable.

Frequently Asked Questions

What if they deny the behavior when I raise it?

Stay grounded in specific examples rather than general claims. 'On Tuesday at 2pm' is harder to deny than 'you always interrupt me.'

When should I involve HR instead of handling it directly?

If the behavior involves harassment, discrimination, or a pattern that hasn't changed after a direct conversation — escalate to HR.
