Your Employee’s Behavior Changed. Did You Ask Why?

Late twice this week. A missed deadline from someone who never misses deadlines. A sharp comment in a meeting that didn’t sound like them at all.

When behavior changes, most managers know what to do with the behavior. Talk about the lateness. Reset the deadline. Address the tone. That’s all reasonable, and sometimes it’s necessary.

But it skips a question that matters more: what changed?

The behavior is the signal, not the story

Behavior is what we can see. It’s the visible part of something we usually can’t see: workload, health, family, confidence, a conflict with a coworker, a decision that landed badly, a job offer somewhere else.

When we manage only the behavior, we might get the behavior to stop. We rarely solve the thing causing it. And the person walks away knowing that their manager noticed the lateness, but not them.

The question I want every leader to keep asking themselves is a simple one: Am I managing the behavior, or have I taken the time to understand the person?

Something feels off: start with their baseline

The most useful comparison isn’t between this person and your ideal employee. It’s between this person and their own normal.

Someone who has always been quiet being quiet isn’t a signal. Someone who has always been engaged going quiet is. Someone who regularly runs a little behind running behind isn’t news. Someone who is never late being late three times in two weeks is.

That change from baseline is your data. It doesn’t tell you what’s happening. It tells you that something is.

Ask one more question

You don’t need a formal meeting or a script. You need a private moment, a specific observation, and an open question.

Something like:

“I’ve noticed you’ve been coming in later the last couple of weeks, and that’s not like you. How are things going?”

Then stop talking.

A few things make this land better:

• Name the behavior, not a label. “You’ve been late” is observable. “You seem checked out” is a judgment they’ll want to argue with.
• Make it about them, not the rule. “That’s not like you” tells them you know their normal.
• Leave room for “I’m fine.” If that’s their answer, you can accept it and still leave the door open: “Okay. If anything changes, I want to know.”

Curiosity doesn’t remove accountability

This is where some managers get nervous. If I ask why, am I letting them off the hook?

No. You can care about the person and still hold the standard. You can create accountability and still ask what changed. In fact, accountability is usually better when it’s informed. You’ll make better decisions about flexibility, workload, or next steps when you understand what’s actually going on.

If they share something personal, like a health issue or a family situation, you don’t need to fix it, and you shouldn’t dig for details. Thank them for telling you, ask what would help, and point them toward support your organization offers. If it touches on medical issues, leave, or accommodations, that’s the moment to loop in HR so you’re handling it fairly and correctly, rather than improvising on your own.

And if the conversation reveals there’s no underlying cause, just a performance gap, that’s useful too. Now you can have a clear, direct conversation about expectations, knowing you asked first.

Zoom out

Before you sit down with them, check whether it’s really just them.

• Did something change on the team? New workload, new process, new people?
• Did something change with you? A tough conversation, a decision they disagreed with, less time together?
• Are others showing similar signs?

Sometimes the change in one person is the first visible sign of a change in the whole system.

Adapt it

• If you’re naturally direct: Naming the behavior is useful. Leading with consequences isn’t. Ask first.
• If they’re a private person: Checking in is useful. Pushing for details isn’t. Make it easy to say a little, not everything.
• If you lean toward empathy: Compassion is useful. Ambiguity about the expectation isn’t. You can be kind and still be clear.

Try this

Think of one person on your team whose behavior has shifted recently, even slightly. Before your next one-on-one, write down:

1. What you’ve observed, in one plain sentence.
2. What their normal looks like.
3. One open question you could ask.

Then ask it. Not to diagnose them. Just to understand them a little better than you did yesterday.
