Best way to handle this would be TALK. The best way to handle someone taking credit for your work is through clear communication. Set up a meeting with the person, address the situation calmly, and understand their perspective. Be prepared with your points in case they push back. If the issue is significant, involve your manager and suggest a conversation between all parties to clarify contributions. Approaching this professionally will help resolve the issue while maintaining good relationships. Ultimately, open and honest communication is key in situations like this.

Start by actively listening to them—really hear what they say, and show you’re engaged by paraphrasing their points. Next, express your feelings assertively, focusing on your experience rather than blaming them. For example, say something like, “I feel my contributions weren’t fully recognized.” Self-awareness is crucial, so check in with your emotions before the conversation. Stay calm by using deep breathing if needed. Choose your words carefully, aiming for a respectful tone that encourages collaboration rather than conflict. Finally, try to see things from their perspective; this empathy can lead to a more productive discussion and help strengthen your working relationship.

You could communicate directly. Have a private conversation with the team member who is taking credit. Express your concerns calmly and professionally, and provide specific examples of the behavior that is troubling you.
