My Coworker Took Credit for My Work. How Do I Address It?
Your colleague is presenting the project. The analysis you prepared is described as their work, and nobody mentions your part. You want the record corrected, but you do not yet know whether the omission was deliberate. Start with the attribution you can describe, rather than the explanation you fear.
Identify exactly what was attributed to your coworker, what you contributed and what existing records support it. Decide what needs correcting and who can make that correction. Ask for that specific change without claiming to know the motive. Their response, and whether the attribution is actually corrected, will give you more information for the next step.
What exactly did people hear?
Write down the meeting, message or report and the attribution that concerned you. “I developed the analysis” is different from “I am presenting our analysis.” Being thanked for delivering a presentation is also different from being credited with creating everything in it. If you do not remember the precise words, record your recollection as a recollection, not as an exact quotation.
Then ask who received that account and whether it is now being used somewhere else. An inaccurate line in a report may need changing before the report goes further. A passing omission in a meeting may call for a clarification in the next update. The audience and the consequence help determine the correction; they do not establish intent.
Separate your part from the shared work
Describe the task you actually did: proposed the original approach, gathered the data, wrote a section, checked the calculations or developed the final version. Be equally clear about what others contributed. If the project changed through joint work, asking for accurate shared credit is different from claiming sole ownership.
Check any agreement about who would present and how contributors would be named. You may discover that everyone assumed something different. That ambiguity does not erase your work, but it gives you a more accurate starting point than assuming a colleague knowingly broke an agreement.
Use the records that already exist
Relevant drafts, task assignments, messages and the version history of a shared file may show who did which part. Use material you are entitled to access and follow workplace rules for handling it. You do not need to search someone else’s account, make secret recordings or collect unrelated material to raise an attribution question.
A record supports the contribution it actually shows. An early suggestion may establish where an idea began without proving that you produced the whole final result. Where the record is incomplete, say what you can show and what still needs clarifying. Keep the request about the work, rather than building a case about the person’s character.
Choose the correction and the recipient
Would adding your contribution to the final report solve the problem? Does an email need correcting for the people who received it? Does the project owner need an accurate account before evaluating the work? A private apology may matter personally, but it does not itself correct an inaccurate account already given to other people.
For an ordinary omission your coworker can amend, a direct conversation may be a reasonable first step. If the attribution is part of a manager’s decision or a project record, the manager or project owner may be the relevant recipient. If a deadline makes waiting consequential, raise the correction with the person responsible in time. There is no rule that you must always speak privately first.
Keep the request concrete: “The report lists you as having prepared the analysis. I collected and analysed the data, as shown in the shared draft. Can we update the report to reflect that before it goes out?” You can be direct about an inaccurate statement without adding “you tried to undermine me.” If the attribution itself is unclear, ask how the contributions were being represented before demanding a particular amendment.
The response is new information
If your colleague acknowledges the omission, agree what will be changed, who will do it and when it will reach the affected audience. Check the corrected version rather than treating agreement as completion. If they dispute your account, return to the specific tasks and records; find out which contribution is actually contested.
An explanation may make the situation clearer, but neither a friendly response nor a defensive one proves the original motive. What matters for the immediate problem is whether the representation becomes accurate. If it remains unresolved, ask the relevant project owner to clarify the contributions and decide how the record should read.
If the attribution keeps happening
Keep a factual record of distinct incidents and the corrections requested. Before the next joint deliverable, agree how roles and credits will be recorded. If the same issue recurs despite clear agreements, bring the documented pattern to the appropriate manager or organizational channel. You can describe repetition without declaring sabotage or diagnosing a coworker.
A formal employment, retaliation, discrimination, contractual or intellectual-property dispute needs the appropriate organizational process and, where necessary, qualified professional advice. This page cannot determine rights or the safest formal route. Its ordinary communication task is narrower: establish the contribution and ask for an accurate account.
