Over the years, I have spoken to thousands of people about their working lives. Some conversations are exciting. They are about ambition, promotion, new opportunities and what comes next.
Others are very different.
They usually begin more quietly. Someone who has always been capable and dependable tells me they are struggling to concentrate. Sunday evenings have become something they dread. Small problems at work are affecting them far more than they used to. They are exhausted, frustrated and beginning to question whether they are still good at a job they may have done successfully for years.
Eventually, they say something along the lines of, “I think I’m burning out.”
What is striking is how often these people have been struggling for much longer than they realised.
Burnout rarely announces itself dramatically. More often, it creeps into someone’s working life gradually. A particularly busy month becomes a busy quarter. Staying late occasionally becomes normal. Someone leaves the team and their workload gets redistributed. Emails creep into evenings. Lunch breaks disappear. Holidays are postponed because there never seems to be a convenient time to take them.
Individually, none of these things necessarily feels significant.
Together, over time, they can completely change someone’s relationship with work.
When Tired Becomes Something More
Everyone gets tired at work. A difficult week, a major project or a particularly demanding period can leave anybody needing a weekend to recover.
The warning sign is when recovery stops happening.
People often describe reaching a point where they never quite feel restored. They may arrive at work already feeling depleted. Tasks that previously felt straightforward require more concentration. Patience becomes shorter. Motivation drops and relatively minor problems begin to feel disproportionately difficult.
One of the saddest things I have seen in recruitment is what this can do to someone’s professional confidence.
A person who has spent years building a successful career suddenly starts questioning whether they are capable anymore.
They tell themselves they have lost their edge.
Sometimes they begin looking for another job because they assume the role or profession is no longer right for them. Yet when you explore what has actually changed, their ability is rarely the issue.
They are trying to make judgements about their career while running on empty.
That distinction matters.
The Reliable Person Can Be Particularly Vulnerable
There is a pattern I have noticed repeatedly throughout my career.
The people who become overloaded are often the people everybody trusts.
They are competent. They meet deadlines. They solve problems. When something needs doing urgently, managers know they can rely on them.
So another responsibility lands on their desk.
Then another.
Because they continue delivering, nobody necessarily realises there is a problem. Sometimes the individual does not recognise it either. Being busy can initially feel like being valued.
But capability does not create unlimited capacity.
Eventually, the dependable person becomes the default solution to every problem, and their reliability starts working against them.
This is why workload needs to be judged by sustainability rather than simply by whether somebody is currently managing to get everything done.
There is a significant difference between I can do this and I can continue doing this indefinitely.
Good managers understand that difference. Good professionals need to understand it too.
Work Does Not Happen Separately From Life
Another mistake we make when talking about burnout is treating people as though they arrive at work with exactly the same amount of energy every morning.
Life does not work that way.
Someone might be dealing with bereavement, caring responsibilities, relationship difficulties, financial pressure or simply a particularly demanding period outside work. The workload they managed comfortably six months ago may suddenly feel very different.
That does not mean their standards have disappeared.
It means their available capacity has changed.
Unfortunately, this is often the point where people push themselves harder because they are worried about appearing less committed. They compensate. They stay later. They take work home. They say yes when they really need to discuss priorities.
For a while, that can hide the problem.
Eventually, something usually gives.
When Work Starts Taking Everything
Perhaps one of the clearest warning signs is when work begins consuming the parts of life that normally help you recover from it.
You stop exercising because you are too busy.
You cancel plans because something needs finishing.
You check emails while watching television. You wake during the night thinking about tomorrow’s problems. You take annual leave but spend half of it monitoring what is happening without you.
Slowly, work stops being part of life and begins occupying all of it.
There is an obvious irony here.
People often make these sacrifices because they want to perform better, yet the lack of recovery can make good performance increasingly difficult. Concentration suffers. Decision-making becomes harder. Simple tasks take longer. That creates more work, which encourages longer hours.
A cycle begins.
Working harder is not always the answer to having too much work.
Sometimes it is the thing making the problem worse.
The Importance of Having People Around You
One factor that does not receive enough attention is isolation.
A difficult job can feel completely different depending on who you are doing it alongside.
When people have supportive colleagues and a manager they can speak openly with, pressure can be shared. Problems are discussed before they become crises. Someone notices when another person is unusually quiet or clearly overloaded.
Without that support, relatively ordinary workplace difficulties can become much heavier.
I have spoken with candidates who struggled silently for months because they did not feel comfortable telling anybody what was happening. Their manager assumed everything was fine because the work kept getting completed.
By the time the conversation finally happened, the individual had already decided they needed to leave.
Sometimes organisations lose excellent people not because the original problem was impossible to solve, but because nobody talked about it early enough.
Asking for Help Is a Professional Skill
Many high performers are uncomfortable saying they are overloaded.
They worry that asking for support will make them appear incapable. So instead of discussing workload, they quietly absorb it.
There is a better way.
If three important pieces of work all need completing at the same time, asking your manager which should take priority is not failure. It is sensible workload management.
If a new responsibility is added, discussing what needs to move in order to accommodate it is reasonable.
You do not necessarily have to say, “I can’t cope.”
You can say, “I can take this on, but I currently have X and Y due this week. Which would you like me to prioritise?”
That changes the conversation.
You are not refusing responsibility. You are making the trade-off visible.
Strong professionals do this well because they understand that managing capacity is part of delivering consistently good work.
Boundaries Usually Start Small
People sometimes imagine boundaries as dramatic confrontations with employers.
Usually, they are much less exciting than that.
It might mean taking your lunch break rather than eating at your desk every day. It could mean switching work notifications off when you are not expected to be available. It might involve using annual leave instead of continually postponing it.
It can also mean becoming more comfortable with the fact that not everything can always be urgent.
The difficult part is that nobody else can completely manage these boundaries for you.
A good employer can create the right environment, but professionals also need to recognise when their own habits are contributing to an unsustainable pattern.
If you answer every email immediately at 10pm, eventually people may assume you are available at 10pm.
Patterns become expectations surprisingly quickly.
Do Not Make Every Career Decision From Exhaustion
This is particularly important from a recruitment perspective.
There are absolutely situations where leaving is the right decision. Some workloads genuinely are unreasonable. Some cultures do not improve. Some managers repeatedly ignore concerns. No amount of personal resilience can turn a fundamentally unhealthy working environment into a good one.
But exhaustion can also affect how we interpret everything around us.
When someone is depleted, every problem can begin to feel permanent. A difficult colleague feels unbearable. A frustrating policy becomes the final straw. A career that once felt rewarding suddenly appears completely wrong.
Before making a major career decision, it is worth asking whether you dislike the profession, the organisation, the particular circumstances you are working under — or simply the way you currently feel while doing it.
Those are not necessarily the same problem.
Sometimes the answer is a new job.
Sometimes it is a conversation with your manager, a change in workload, proper time away, additional support or clearer boundaries.
The important thing is identifying the problem accurately before choosing the solution.
A Career Has to Be Sustainable
One of the biggest lessons recruitment teaches you is just how long a working life actually is.
A career can span thirty or forty years. You cannot approach that kind of timescale as though every month is the final sprint.
There will be periods when extraordinary effort is required. Businesses have difficult months. Teams become stretched. Important projects need completing. Careers sometimes demand more from us.
But exceptional effort cannot become the permanent operating model.
The people who build strong careers over decades are not necessarily the people who can tolerate the most pressure. They are often the people who become good at recognising their limits, communicating early, recovering properly and understanding what they need in order to perform consistently.
That is not a lack of ambition.
It is what makes ambition sustainable.
If work has started feeling noticeably heavier than it once did, pay attention to that change. Do not immediately assume you need to resign, and do not automatically tell yourself you simply need to become tougher.
Get curious about what has changed.
Is the workload realistic? Are you recovering properly outside work? Have responsibilities increased without anything else being removed? Are you trying to carry problems that should be shared? Have you spoken honestly with the people around you?
Sometimes those questions reveal a problem that can be fixed.
Sometimes they confirm that it really is time to move on.
Either way, recognising what is happening early gives you choices.
And ultimately, that is the point.
Your career should challenge you. It should stretch you occasionally. There will inevitably be difficult weeks and demanding periods.
But it should not require you to permanently exhaust yourself simply to remain in it.
The strongest career is not the one you survive.
It is the one you can sustain.
