Andrea Belk Olson: A meddling coworker is a symptom, not a disease

Every organization has one, that colleague who weighs in on decisions that aren't theirs, redirects work they don't own and offers detailed opinions on how you should be running things. The standard advice is to have a calm, direct conversation and politely ask them to stay in their lane.

That advice isn't wrong. It's just aimed at the wrong target. Most overstepping isn't a character flaw. It's a response to an environment that left a question unanswered.

People rush to fill a vacuum

Behavioral science is consistent on this point: human beings are deeply uncomfortable with ambiguity, especially when they feel accountable for an outcome. When it isn't clear who owns a decision, someone moves into it. Usually it's the most confident, most invested, or most anxious person in the room — and from your view, that looks exactly like meddling.

Before you label the behavior, look at the conditions that produced it. Is the boundary of your ownership actually clear, or is it clear only to you? Has anyone said out loud who makes the final call on this work? When two capable people both believe a decision is theirs, the resulting friction isn't solely a clash of egos, but also a design flaw.

The difference between collaboration and encroachment

This matters because the natural reaction of telling people to mind their own business can do as much damage as the problem. The organizations that perform best are the ones where people think beyond their own turf. You don't want to train that instinct out of your team — you want to channel it.

A colleague offering a perspective on your work is collaboration. A colleague overriding your decisions or directing your team is encroachment. The line between them has nothing to do with how much people care. It has everything to do with whether everyone agrees on who decides.

Fix the structure, then have the conversation

This is where clarity does the work that confrontation can't. When a team operates from a shared set of commitments — what we're trying to accomplish, and who owns which part of getting there — the ambiguous areas shrink. People still contribute across lines, but they do it as input rather than override, because the decision rights are no longer up for grabs.

That's the important power of a clear decision framework. It doesn't only tell people what the organization is trying to do, it establishes how choices get made and by whom, which means the ambiguity that invites overstepping never forms in the first place. The meddler has nothing left to do.

You'll still occasionally need the direct conversation, and when you do, have it. But frame it around clarity, not territory. “I want to make sure we're clear on who owns this” is very different than “stay out of my work.”

The meddling coworker is rarely the real problem. It’s almost always the unanswered question about who's genuinely in charge of what, and putting that conflict out is leadership's job.
