Why You Lose Your Strongest People to Burnout First
David Buirs is a leadership coach in Amsterdam. In this article he shares, from his own experience as a manager, how to spot an approaching burnout in a team member early. You will learn three warning signs and what you can concretely do to help.
Burnout rarely comes out of nowhere. The person feels it building for months. They're tired, they sleep badly, and the worry never fully switches off. They just don't say anything. Out of shame, or because the work has to get done.
And you, as their manager? You often miss it. You look at the output, and the output holds up for a long time. They keep delivering, right up until the moment they can't anymore.
Preventing burnout as a manager comes down to one thing. Learning to see what's easy to miss, early, while you can still help. There are three signals you can catch before it's too late.
A quick note first. I'm not a doctor. This comes from my own experience as a manager. If you have any doubt about someone's health, always involve your occupational health physician.
Why performance points you the wrong way
Output is a weak measure. The people heading for burnout often keep performing well for a long time. They compensate, until they fall over.
That's exactly where the danger is. The qualities that make someone a star are the same ones that raise the risk. Perfectionism. Drive. Always finishing everything, always going one step further. That produces great work. And it pushes someone past their own limit, again and again.
Your strongest people rarely ask for help. They'd rather sort it out themselves. So you have to learn to watch something other than the output.
Signal 1: their engagement drops off
Watch for changes in how someone takes part. A team member who goes quiet in meetings. Who stops bringing ideas. Who runs on autopilot where there used to be energy.
Researchers call this mental distancing. It's one of the clearest early signs of burnout. The person still does what's needed, but they care noticeably less.
Signal 2: the physical signs show up
Pay attention to the body. More frequent short sick days, headaches, quicker irritation, a shorter fuse than usual.
Energy that never fully returns belongs here too. When someone needs an hour to recover after an ordinary workday, or a whole weekend, something is off. The body often shows this long before anyone dares to say the word burnout.
Signal 3: the habits that pile up
Watch the behaviour around working hours. Someone who keeps answering emails in the evening and at weekends. Who hasn't taken a day off in months. Who comes back from holiday still exhausted.
Say something about it. Encourage people to actually use their holiday days, and to close the laptop after hours. It sounds small, but working non-stop without recovery is exactly how people run themselves empty.
Your own habits set the tone here. Some executives even add a line to their email signature: "I sometimes send emails outside office hours because I like to work in the evening. Please don't feel you have to reply outside your own hours." A small message like that gives people permission to switch off.
Ask, and ask the right thing
Most managers ask about the progress of the work. Ask instead how the person is really doing.
A fixed moment each week, just to catch up, is your best early warning. Not about deadlines, but about how the week felt. Be open about your own limits too. When you admit that something was too much for you, you give others permission to do the same.
Check whether the cause sits outside or inside
Once you notice someone struggling, it helps to know where it comes from. The causes fall roughly into two boxes, and what you can do about them is different for each.
The first box is the work itself. Too much on their plate, too little time to think, back-to-back meetings with no gap to breathe. Clients who ask too much. Being interrupted all day. Unclear expectations. You can do a lot here. You redistribute the work, free up time, help with priorities.
The second box is the person themselves. That perfectionism and that drive from earlier. Not being able to let go of work after five. Demanding far more of themselves than you'd ever ask. Here you can only get so far as a manager, and that's important to know.
Adjust the work, even when the pressure is internal
I once had someone on my team who was making herself ill with stress. She wanted to outperform everyone around her. I kept telling her she was doing well. That it was enough. It barely made a difference.
That pressure came from within. From a bar she'd set for herself, long before she ever worked with me. How someone thinks about themselves is something you can't rewrite for them.
What you can do, when you're genuinely worried about someone's health: step in on the work. Force them to do less if you have to. Take tasks away. Those are levers you can pull, even when the cause is internal. Sometimes that's the only thing that protects someone from themselves.
Guard your own calm
Watch your own example too. Mood is contagious. If you rush around all day and fire off emails at eleven at night, your team picks up on it. Someone who never pauses tells the team, without words, that pausing isn't allowed.
A manager who stays calm makes the team calmer. You show that something matters without spreading panic. The message becomes: this counts, and we'll handle it together.
Why this is worth it
Burnout hits the person hard. Months at home, sometimes more than a year. And it hits the organisation hard too. An employee on burnout leave quickly costs an employer tens of thousands of euros. That's on top of the pressure that lands on the rest of the team.
Seeing it early pays off twice, then. For the person, and for the business.
In leadership coaching we practise exactly this kind of thing. How to pick up early signals, how to open a good conversation, and how to stay calm under pressure. For leaders at director level, coaching for senior leaders is a natural next step.
