Work-Related Stress: When Does Pressure at Work Become a Mental Health Problem?

You finish work, but work doesn't really finish with you. You're making dinner while thinking about tomorrow's meeting, checking one email before bed and somehow ending up answering three, or waking at 3am because you've suddenly remembered something you forgot to do.

Then Sunday afternoon arrives and Monday already seems to be sitting heavily in the background.

Because you're still turning up, meeting deadlines and getting things done, it can be easy to tell yourself:

"It's just work. Everyone gets stressed."

Some pressure at work is normal, of course. But there is a point where pressure stops being temporary and starts affecting how you feel, sleep, behave and live outside work. That is when it is worth paying attention.

What Is Work-Related Stress?

Work-related stress is more than having a particularly busy day. The Health and Safety Executive describes stress as the adverse reaction people can have to excessive pressures or demands placed upon them.

And this is far from a minor issue.

In 2024/25, an estimated 964,000 workers in Great Britain were experiencing work-related stress, depression or anxiety, with 22.1 million working days lost as a result.

BACP's 2026 research also found that 19% of adults reported work-related burnout, rising to 30% among 25–34-year-olds.

So if work is beginning to affect your mental health, you are certainly not alone.

When Does Normal Work Pressure Become Unhealthy?

One of the simplest ways to think about this is to ask:

Do you recover?

A demanding week can leave anyone tired. A deadline might mean working later than usual, and a difficult project may temporarily occupy your thoughts outside work. But ordinarily, the deadline passes, the project ends and, after some rest, you begin to feel like yourself again.

Work-related stress becomes more concerning when that recovery stops happening.

You finish work but remain mentally at your desk. You take annual leave and spend the first few days simply trying to come down from the previous few months. Weekends stop feeling restorative and become little more than recovery periods before you have to start again.

That is different from simply having a busy job.

Signs Work Stress May Be Affecting Your Mental Health

Stress does not look exactly the same in everybody. You may notice that you're becoming unusually irritable or impatient, finding it harder to concentrate on tasks you would previously have managed easily, or feeling anxious before work.

Some people lose confidence in their ability or feel emotionally exhausted by relatively ordinary requests. Sleep may become disturbed, and you may find yourself drinking more because it feels like the only way to switch off. Others begin withdrawing from friends because they simply do not have the energy.

There can also be a persistent feeling that, no matter how much you do, it is never enough.

One difficult week does not necessarily mean you are burning out. It is the pattern, persistence and impact that matter.

Why Capable People Can Miss the Signs

Sometimes the people most vulnerable to excessive work pressure are also the people least likely to admit they are struggling.

You may be known as reliable, the person who gets things done, the one who does not complain and the colleague everyone turns to when something goes wrong. If that has become part of your identity, saying:

"I can't keep doing this"

can feel remarkably difficult.

You may interpret exhaustion as weakness rather than information, so you work harder, become more organised, stay later, answer emails at night and skip lunch. Because you can keep functioning for quite a long time, everyone—including you—assumes you're coping.

One point worth remembering is this:

Being able to cope with an unreasonable workload doesn't necessarily make the workload reasonable.

The Problem Isn't Always Your Resilience

Workplace wellbeing advice can sometimes put too much responsibility on the individual.

Exercise more. Meditate. Be resilient. Take regular breaks.

All of those things can be useful, but no amount of mindfulness can solve chronic understaffing. A lunchtime walk cannot fix bullying, and better breathing techniques will not change an impossible workload or a manager who contacts you constantly outside working hours.

The Health and Safety Executive treats work-related stress as a workplace health risk that employers have responsibilities to assess and manage. CIPD research has also found that employees commonly identify high workloads and poor workplace relationships among the factors harming their mental health.

Sometimes personal boundaries need attention. Sometimes the workplace itself needs to change. Often it is a mixture of both.

When Work Follows You Into Bed

Sleep is often one of the first things people mention when work becomes too much.

You are physically tired, but your mind is still holding a meeting. You replay a conversation with your manager, draft tomorrow's email in your head, remember another task and perhaps check your phone just once more.

Then you look at the clock and realise you've been awake for two hours.

The following day, tiredness makes concentration and patience harder. Tasks take longer, you fall further behind, and you may stay later to compensate. It is easy to see how a cycle develops.

CIPD research has identified sleep problems and anxiety among common health concerns for employees, with work an important contributing factor to poor mental health for many people.

What Happens When You Can Never Switch Off?

Technology has made some working lives much more flexible, but it has also made disappearing from work much harder.

Your office can now live in your pocket.

Nobody may explicitly tell you to answer a Teams notification during dinner, but you see it. You know somebody is waiting, so you reply. Then somebody answers, another message appears, and before long part of your evening has been spent mentally dipping in and out of work.

It may be worth asking yourself:

When was the last time you were genuinely unavailable to work?

Not technically off. Actually unavailable.

There is a difference.

Work Stress Rarely Stays at Work

Unfortunately, the people we live with often experience the consequences of workplace stress too.

You may come home with very little patience left, snap at your partner over something small, feel overwhelmed by noise or withdraw from friends because you simply have no energy.

You can also end up sitting beside someone you love while thinking entirely about tomorrow's workload.

Then guilt arrives.

"Why am I taking this out on everyone else?"

Now it can feel as though you are failing at home as well as struggling at work.

Stress has a habit of spreading beyond the place where it started.

Burnout Doesn't Always Look Like Falling Apart

People sometimes imagine burnout as the moment somebody simply cannot go to work anymore. It can reach that point, but it does not always begin there.

You may still be productive, still get promoted and still meet deadlines. From the outside, very little may appear to be wrong.

Internally, however, you may notice that you no longer care about work in the way you once did. You feel cynical, detached or irritated by everything. Tasks that used to feel straightforward seem much harder, and although your work is still getting done, it is costing you much more to do it.

That change is worth noticing.

What Can You Do About Work-Related Stress?

Before trying to fix everything, it can help to identify what is actually creating the pressure.

Is it workload, a difficult manager, conflict with colleagues, lack of control, job insecurity, perfectionism, difficulty saying no or fear that setting boundaries will damage your career?

For many people, it is a combination of several things.

Once the pressure is clearer, it becomes easier to think about what might realistically change. That could involve speaking with a manager, HR, occupational health or an Employee Assistance Programme. It may mean talking with your GP or considering whether the role, team or organisation remains sustainable for you.

Can Counselling Help With Work-Related Stress?

Yes.

Counselling cannot make an unreasonable manager reasonable or remove fifty emails from your inbox. What it can do is give you somewhere confidential to look at what work is doing to you and what may be keeping you stuck.

In counselling, we might explore why saying no feels so difficult, whether perfectionism or fear of failure is driving you, how imposter feelings are affecting confidence, or whether work has become too closely tied to your sense of worth.

Sometimes the question is not simply:

"How can I cope better?"

It may be:

"Why am I having to cope with this much in the first place?"

Those are very different questions.

When Might It Be Time to Ask for Support?

You do not have to wait until you're signed off work.

If work is regularly affecting your sleep, relationships, mood or physical wellbeing, it may be worth doing something before you become completely depleted.

Pay attention if you can no longer switch off, dread the working week, feel permanently exhausted or notice that you're increasingly relying on alcohol or other behaviours simply to escape how you feel.

You do not need to prove that you are burnt out enough. If work is affecting your life, that is worth talking about.

You Are More Than Your Productivity

Work can be important. It may provide income, purpose, identity, friendships and a sense of achievement.

But it is possible, over time, to start measuring ourselves almost entirely by what we produce.

How much did I achieve? Was I good enough? Did everybody think I performed well? Did I get everything done?

There will almost always be another email, another deadline and another target.

Being committed to your work and protecting your mental health are not opposites.

Sometimes recognising that something needs to change is not giving up. It is paying attention before your mind or body forces you to.
