Someone on the team who always raised their hand for everything stops doing it. They show up to the daily right on time, answer in monosyllables, close what they have to close and not one ticket more. In the one-on-one they say everything's fine, just a bit tired. Two months later they ask for leave. Or they quit.
And the first reaction is almost always to look at the person. They couldn't set boundaries, they took everything too personally, maybe they weren't cut out for the role.
In its 2019 classification, the World Health Organization describes burnout syndrome as the result of chronic workplace stress that hasn't been successfully managed. It explains it through three dimensions: an exhaustion that doesn't go away over a weekend, a detachment from work that often looks like cynicism, and the feeling of being less and less effective.
There's a detail in that definition that I think is key: the WHO places it at work. The person is where it shows, but if the stress comes from work, what needs reviewing is the load and how the work is set up.
It's like driving in first gear on the highway. The engine screams, you're going twenty-five miles an hour, you burn three times the gas, and if you keep it up long enough something breaks. When it breaks, nobody blames the engine. You blame whoever didn't shift gears.
On teams we do it the other way around and blame the engine.
Plans built for an ideal team that only exists in a spreadsheet. Emergencies that become the normal way of working. Priorities that change every two weeks and throw away what was already done. People doing the work of two because nobody covered for whoever left. And the usual line, "it's just a crunch, it'll calm down after". It never calms down.
The first thing to let go of is the idea that burnout gets fixed with individual resilience. Sending someone to a stress management workshop while the system stays the same is changing the oil on a car you're going to keep driving in first.
Then, paying attention earlier. If someone who used to participate a lot stops giving opinions, stops arguing and accepts everything, it's worth reaching out and asking how they're doing. A team that doesn't push back on anything is usually more tired than aligned, and it looks a lot like living in the panic zone, where nothing gets learned because all the energy goes into surviving.
And finally, leading is taking responsibility for the load we put on the team too, for the commitments we accepted without negotiating and for every time we said yes knowing someone else was going to pay the cost.
Burnout doesn't get cured with a vacation if the same job is waiting for you when you get back.
More and more I think of leadership as design and less as pushing. Designing how much a team can sustain, what stops getting done when something new comes in, where there's slack so that a bad week doesn't turn into a bad quarter.
I don't know if there's a team that's immune to this. But when someone burns out, it rarely happened overnight. And often there was someone who could have shifted gears and kept driving in first.
