ASK COACH LANI: My coworker keeps taking credit for my ideas. How do I address it without looking petty?

Q: My coworker keeps taking credit for my ideas. How do I address it without looking petty?

Protecting your contributions is not petty. Your work, ideas, and results are part of your professional reputation.

But before you march into your manager’s office and announce that your coworker is stealing your ideas, make sure you’re looking at the entire situation strategically.

First, ask yourself whether this happened once or whether you’ve noticed a pattern. Miscommunication happens. People sometimes build on ideas without intentionally taking credit. But if someone repeatedly presents your ideas as their own, leaves your name off work you’ve contributed to, or positions themselves as responsible for results you produced, that’s different.

Start by making your work more visible.

If you have an idea in a meeting, say it. If you develop a recommendation, put it in writing. If you’re leading a project, provide updates. After an important discussion, send a concise follow-up summarizing decisions, next steps, and responsibilities.

This isn’t about constantly announcing, “Look what I did.”

It’s about creating a clear record of your contributions.

If someone takes credit for your idea in real time, you can also correct the situation without turning the meeting into a confrontation.

You might say: “Yes, that’s the idea I raised when we discussed this last week. I’ve done some additional thinking about how we could implement it.”

Then continue with your recommendation.

You’ve reclaimed your contribution without accusing anyone or derailing the conversation.

If the behavior continues, however, it may be time for a direct conversation with the coworker. Keep it focused on specific behavior rather than assumptions about their intentions.

For example: “I’ve noticed a few instances where ideas or work I’ve contributed have been presented without my involvement or attribution. Going forward, I’d like us to be clearer about our respective contributions when we’re presenting this work.”

Then pay attention to what happens next.

If the pattern continues and begins affecting your reputation, performance evaluation, visibility, or opportunities for advancement, document specific examples and talk with your manager.

And here’s the bigger career lesson: doing excellent work is only part of career management. People also need to understand the value you’re contributing.

You shouldn’t spend your career screaming for credit for everything you do. But you also shouldn’t consistently do the work behind the scenes while someone else builds a reputation from it.

Visibility isn’t bragging. It’s making sure your work doesn’t become invisible.

Coach Lani’s Next Move: Think about your biggest contribution from the last 30 days. If I asked your leadership team who was responsible for it, would they know it was you? If you’re not sure, it’s time to work on your visibility.
