How to Tell a Colleague Their Work Is Affecting the Team

Telling a colleague that their work is affecting the team is a conversation that most people either avoid entirely or handle badly — either by saying nothing until the situation becomes critical, or by saying something in a way that feels like an attack rather than feedback. The middle path, which is honest and specific and delivered without judgment, is both harder and more useful than either extreme.

This conversation is also, depending on your role, sometimes necessary. If you're the manager, it's your job. If you're a peer, it's more of a judgment call — but a peer who can have this conversation honestly is often more effective than waiting for it to escalate to management.

Be specific about the impact

General feedback is easy to dismiss. "Your work has been slipping" is a verdict. "The last three reports had errors that I had to catch before they went to the client, and it's taking time I don't have" is specific enough that there's something concrete to address. The specificity isn't punitive — it's what makes the feedback actionable.

Focus on the impact to the work, the team, and the output rather than on the colleague's character or effort. "This is creating downstream problems" is different from "you don't care about quality." The first can be addressed. The second just makes the person defensive.

Ask before you assume

Before delivering a verdict, consider asking what's going on. "I've noticed things have been harder lately — is everything okay?" gives the person a chance to tell you there's something happening that you don't know about. They may be dealing with something personal. They may be unclear on expectations. They may not even know there's a problem. The answer changes what the conversation needs to be.

If there's a real issue affecting their work, you finding out is better for everyone than you delivering feedback without that context.

Be direct without being harsh

"I wanted to talk to you directly because I think you'd want to know, and because I'd rather address it with you than have it become a bigger issue. I've noticed [specific thing] and it's been creating [specific impact]. I wanted to flag it because I know you care about doing good work."

That's honest, it's specific, and the last sentence matters — it attributes good intention to them while still naming the problem. People respond better to feedback delivered by someone who assumes they want to do well than to someone who assumes they don't care.

This conversation, done well, often lands as a kindness. Most people would rather hear it from a colleague who cares than be blindsided by it from above.
