A coworker takes credit for my work: what to do

Updated November 9, 2026

Talk to your coworker privately first, then make your contributions visible in writing so it can't happen again. Credit-taking usually works because the work was invisible: recaps, your name on files and presenting your own part fix that faster than a fight.

What to do

1. Check the facts. Pull the emails, drafts and file history that show what you did and when. You need dates and specifics, not a feeling.
2. Talk to them one-on-one, soon. Within a day or two, in private. Describe what happened, not their character, and ask how they'll fix it: a correction email, or naming your part in the next meeting.
3. Reclaim it calmly in the room. If they present your work, add: "Glad that landed. When I built that analysis, I also found..." Then share a detail only the author would know.
4. Leave a paper trail. After each meeting on a shared project, send a short recap of who owns what. Put your name on documents and slides.
5. Tell your manager if it repeats. Frame it as visibility, not blame: show what you delivered and ask how to make ownership clear on shared work.

What to say

Say this privately to your coworker, within a day or two:

Hey, can I mention something from the meeting? When the launch plan came up, it sounded like it was your work, and I built most of it. I'm sure it wasn't on purpose, but it matters to me. Next time, can we present it together, or can you mention my part? And could you send a quick note to the team clarifying who did what?

Avoid

• Calling them out in front of the team: it makes you look petty, even when you're right.
• Staying silent and hoping your boss notices: they usually don't.
• Complaining to other coworkers before you talk to the person: it travels fast.
