Work Stress: Common Causes and What You Can Control

Most work stress starts in how a job is designed and run, not in a weakness of the person doing it. The International Labour Organization (ILO) says work-related stress is determined by work organization, work design and labour relations, and that view changes where effort is best spent.¹

The World Health Organization’s (WHO) list of risks to mental health at work includes excessive workloads, low control, limited support, unclear roles, harassment or bullying, and job insecurity. The WHO’s advice to employers starts with changing working conditions; training workers to manage stress comes later in its list.²

That leaves you a smaller but real share. You can often shape the order you work in, how early you flag overload and how you recover after hours. Staffing, deadlines, roles and job security are mostly the employer’s to assess and fix.

The body’s side of the story is in what stress does to your body and brain. This piece, one of the guides to managing stress and anxiety, stays with the job.

What causes work stress: seven conditions that keep recurring

Seven working conditions recur in the lists of what makes work stressful kept by international bodies and national regulators: heavy workload and pace, low control, poor support, unclear or conflicting roles, poor relationships, badly managed change, and job insecurity. The European Agency for Safety and Health at Work (EU-OSHA), whose list names all seven, calls them psychosocial riskspsychosocial risk: A feature of how work is designed, organized or managed that can harm mental or physical health, such as heavy workload, low control, poor support, bullying or job insecurity. Guidance puts changing these conditions ahead of asking workers to cope better.Full entry in the glossary, which arise from poor work design, organization and management, or a poor social context at work.³

The ILO splits them in two: the content of work (workload, pace, hours, task design) and its context (your role, career prospects, how much say you have, relationships, and the pull between home and work).¹

National regulators cut the list differently but land in the same place. The Health and Safety Executive (HSE), Britain’s regulator, uses six areas of work design: the demands of the job, control, support, relationships, role, and change.⁴ Safe Work Australia’s longer list adds poor reward and recognition, unfair treatment, remote or isolated work, and traumatic events.⁵

The practical use of any of these lists is diagnosis. “I’m overloaded” is a feeling; “three deadlines, one of me, and no say in the order” names conditions that someone can change.

Why the same workload can feel fine in one job and heavy in another

Work stress comes from a mismatch, not from effort alone. The ILO describes work-related stress as what happens when the demands of a job do not match, or exceed, the worker’s capabilities, resources or needs.¹

That is why the conditions in the table rarely act alone. Safe Work Australia notes that hazards can combine: a high workload becomes riskier when workers cannot take breaks or there is no one around to help.⁵ EU-OSHA draws the other side of the line: demanding, stimulating work is not a psychosocial risk when people have a supportive setting, enough autonomy and the training to do it well.³

Picture two accountants in the same month-end crunch. One sets the order of her own tasks, has a colleague who covers when she is stuck, and knows the rush ends on a fixed date. The other gets new priorities by message every afternoon, works alone, and has heard the team may be cut. Same hours, very different load. (The example is ours, for illustration.)

When the same conditions drag on for months, they are also where researchers look for the roots of burnout, the subject of what causes burnout at work.

What you can influence: priorities, early warnings and switching off

Three levers are often within an individual’s reach: the order of the work, how early you flag overload, and recovery after hours. The WHO’s 2022 guidelines say stress-management training for workers may be considered, but rate the evidence behind it as low certainty and make only a conditional recommendation, so treat these as sensible habits rather than cures.⁶

The first lever is order. Deciding the sequence yourself gives you back some control over your workload, one of the listed causes, and it turns a vague pile into something you can show a manager. Say a report, a client pitch and a budget review all land on Thursday. Rank them, put a rough number of hours beside each, and the gap between the time you have and the time they need is on paper (our example). A method for prioritizing when everything feels urgent helps with the ranking.

The second is timing. Britain’s HSE tells workers who notice signs of stress to talk to someone, such as their manager, as soon as they can, because early notice gives the manager a chance to help before things get worse. When the pressure comes from the manager’s own actions, it suggests checking workplace policies and talking to people such as a trade union or worker representative, HR or a GP.⁷ Speaking up is harder on an insecure contract or with a difficult manager, which is when those other people can help most.

The third is recovery, and it has a catch. A 2017 meta-analysis pooling 91 samples of employees, paid for by Germany’s federal occupational safety institute (BAuA), found that people who mentally switched off from work in their free time reported less exhaustion and better sleep, while heavier job demands went with less switching off. The links with health were small to medium and the link with demands was small; most pooled studies were one-off surveys or diary studies, so the pattern is not proof of cause. The authors note that guided recovery training has improved switching off in earlier studies, and suggest social and physical activities after work might help too.⁸

So the heavier the job, the harder the evening, which is one more reason to raise a workload problem rather than only absorb it. Switching off can start small: jot down tomorrow’s first task before you close the laptop, then go for a walk, play a sport or meet a friend (our example, in the spirit of the activities the review names). For the personal side, everyday ways to reduce stress compares the habits and their evidence.

Workload tops the list in workers’ own reports, from Europe to Japan

When workers are asked what strains them, heavy workload and time pressure come first. EU-OSHA’s 2025 OSH Pulse survey, Britain’s HSE statistics and a 2025 survey by Japan’s Ministry of Health, Labour and Welfare all put workload at or near the top, although each asked a different question of a different workforce.

The study

Moderate evidence

Which risk do EU workers report most? Time pressure, in EU-OSHA's 2025 survey

In spring 2025 the research firm Ipsos, working for EU-OSHA, polled representative samples of employed people aged 16 and over. Across the EU, 44% said they were exposed to severe time pressure or work overload, the most common of six risks asked about, while 17% reported a lack of autonomy or influence over their work. Separately, 29% said they had had stress, depression or anxiety caused or made worse by work in the previous 12 months.⁹

Read those figures as exposure, not illness: many people who named overload were not unwell, and a single survey cannot show that one caused the other. It does show where the weight sits: the commonest complaint is the amount and pace of the work.

Official national figures agree. In Great Britain, self-reported work-related stress, depression or anxiety made up about half of all work-related ill health in 2024/25, and workers named workload, especially tight deadlines, as the main cause, though those cause data date from 2009 to 2012.¹⁰ In Japan, about two-thirds of workers surveyed in 2025 at private workplaces with 10 or more staff reported strong anxiety, worry or stress about their work, and among them the amount of work tied with mistakes and responsibility as the most-named source.¹¹

Overload rarely arrives as one huge task. More often it is a slow build: a colleague leaves and is not replaced, a new reporting tool adds an hour a week, a client pulls a deadline forward (our examples). Each step is small, so nobody ever decides the job has become too big. A two-week log of what arrived and what slipped turns that drift into something a manager can see.

Myth

Work stress mainly shows that a person is not coping well enough.

Fact

The WHO, ILO and EU-OSHA locate the main causes of work stress in how jobs are designed, organized and managed, and favor preventing risks by changing those conditions.

What employers are responsible for, and what the law says in some countries

In many countries, managing the causes of work stress is part of the employer’s health and safety duty, not an optional extra. In the EU, EU-OSHA says managing psychosocial risks is a legal requirement under the EU’s 1989 Framework Directive (89/391/EEC), and that employers must make sure workplace risks are properly assessed and controlled.³

For Great Britain, HSE guidance updated in January 2026 says employers have a legal duty to protect workers from stress at work by doing a risk assessment and acting on it, and must write it down if they have five or more workers.⁴ Safe Work Australia’s guidance, checked in September 2026, says the country’s model work health and safety laws require a business to eliminate psychosocial risks or, if that is not reasonably practicable, minimize them so far as is reasonably practicable; each state and territory enforces its own laws.⁵ How such an assessment runs is set out in how employers manage psychosocial hazards.

Rules elsewhere differ, and many workers have none of this protection: the WHO notes that more than half the world’s workforce is in the informal economy, with no regulatory protection for health and safety.² Look up your own country’s labour inspectorate or workplace safety regulator for what applies to you.

1. Often within your reach: the order you tackle the work in, how early you say it will not fit, and whether you switch off after hours
2. The employer's to assess and change: staffing and deadlines, how much say people have, clear roles, bullying and abuse, and how change and job security are handled

For action at the source, the WHO recommends that employers use organizational interventions that assess, then reduce, change or remove risks at work, such as flexible working arrangements or a framework for dealing with violence and harassment.² Its guidelines back those interventions only conditionally, on very low-certainty evidence, and back training managers to support their teams’ mental health strongly, on moderate-certainty evidence.⁶ The ILO is plain about the order:

The best way to address work-related stress is by means of strategies to tackle the psychosocial hazards at their source in working conditions

Workplaces do not always follow that order. In the 2025 OSH Pulse survey, about half of EU workers said their workplace offered awareness raising or training on coping with stress, while only about a third reported measures such as changes in how work is organized or clearer priorities.⁹

If work stress is affecting your health: who to contact, and how fast

Stress from work can build into health problems that need care, whatever caused them. The help routes below come from the bodies named; we have grouped them by how urgent they are.

• Right away: if suicide or self-harm is on your mind, or anyone’s safety is at immediate risk, start with your local emergency number. Anywhere in the EU, 112 is the emergency number and costs nothing to call.¹² For US readers, the 988 Suicide & Crisis Lifeline takes phone calls and text messages on 988 at no cost, in confidence, day and night.¹³ UK readers: the NHS directs anyone who needs immediate help to 999 or A&E, and Samaritans take calls on 116 123.¹⁴
• Soon (days or weeks): the NHS points people to a GP when they are struggling with stress or their own efforts are not helping, and to NHS 111 in England for urgent needs short of an emergency.¹⁴ Outside the UK, your own doctor or local health centre is the usual place to begin.
• At your next check-up (our suggestion): work stress that keeps coming back for weeks is worth mentioning, even if it seems small, so it can be looked at before it grows.

The bottom line

Work stress has well-mapped causes: too much work at too fast a pace, too little say, thin support, unclear roles, harassment and insecure jobs.² You can often shape your priorities, how early you raise overload and how you recover, but the conditions themselves are mainly the employer’s to change, at the source.¹ Name the specific condition, and take it to whoever owns it.
