Work stress: symptoms, causes and how to prevent burnout
Pressure at work is normal. Stress that never switches off is not. This guide explains how to recognise the difference, what drives it, and what employees and employers can each do before it becomes burnout.
What work stress actually is
Work stress is what happens when what your job asks of you keeps outweighing what you have to meet it. It is not a personality flaw and it is not the same as being busy. The useful question is how long it lasts and whether you recover.
Pressure → Stress → Overload → Burnout
Most people can name where they are on this line within a few seconds. The point of measuring it is to catch the move from stress to overload, not to confirm burnout after the fact.
Pressure
A deadline, a launch, a difficult quarter. Demands rise, you rise with them, and afterwards you recover. This is normal and often energising.
Stress
Demands stay high while control, support or recovery time fall away. You still function, but evenings and weekends stop restoring you.
Overload
Recovery no longer happens. Sleep gets shorter, irritability rises, small tasks feel heavy, and you start compensating with caffeine, longer hours or withdrawal.
Burnout
Exhaustion becomes persistent, distance from the work sets in, and performance drops in a way rest alone no longer fixes. In the Netherlands stress-related absence averages around 252 days, and burnout around ten months.
Stress is not the enemy
The Yerkes-Dodson inverted-U describes how performance and wellbeing change with demand. Too little demand leads to boredom and disengagement; optimal demand drives peak performance and meaning; too much demand without recovery becomes strain. Work Experience identifies where on this curve your current work situation sits.
Your Work Experience report places you on the demands × resources map — a more diagnostic two-dimensional view of this same curve.
Causes: what actually drives work stress
Work stress is usually a problem with how the job is set up rather than with the person doing it. These are the drivers with the strongest evidence behind them — and the six areas this assessment measures.
Work pressure and demands
Too much work, too little time, frequent interruptions, and no realistic way to say no.
Control and autonomy
Little influence over how, when or in what order the work gets done. High demands with low control is the classic strain combination.
Support
A manager or team that is unavailable, unclear, or unsafe to raise problems with.
Reward and recognition
Sustained effort that is not acknowledged — in feedback, development, or pay. Effort that is never repaid predicts strain on its own, whatever the workload.
Recovery
Not switching off after work, short sleep, no real breaks, and holidays that stop working. How much recovery you need is one of the earliest measurable warning signs.
Work and home
Work spilling into private life — evening messages, mental preoccupation, caring responsibilities colliding with deadlines.
What chronic stress does to the body
Stress is not only a feeling. When the stress response stays switched on, it changes the same systems a health check measures — which is why work stress and physical health belong in one picture, not two separate reports.
- Blood pressure stays higher for longer, and night-time recovery drops
- Blood sugar regulation shifts, nudging people towards prediabetes
- Low-grade inflammation rises, a shared driver across heart and metabolic risk
- Sleep shortens and fragments, which worsens every marker above
- Behaviour changes — less movement, more alcohol, worse food — compound the effect
High blood pressure
High demands combined with low control is the best-evidenced work pattern behind raised blood pressure and heart disease in occupational health research.
Preventa test: Blood pressure at rest, 5 day home test average (ESC protocol)
Over time: Can strain the heart and blood vessels for years without symptoms.
Long-term blood sugar (HbA1c)
Cortisol pushes the body to release more glucose and respond less well to insulin. High pressure with poor recovery is linked to higher long-term blood sugar in working people, whatever their diet or weight.
Preventa test: HbA1c, average blood glucose over 3 months
Over time: An early stage on the path towards type 2 diabetes.
Cholesterol (LDL/HDL)
Chronic cortisol elevation promotes fat production in the liver, raising LDL cholesterol. Effort that is never repaid is linked to worse cholesterol profiles over time, independently of workload.
Preventa test: Full lipid profile (HDL, LDL, total, ratio)
Over time: Builds up in the arteries gradually and quietly.
Excess body fat
Chronic cortisol encourages fat to settle around the abdomen. Poor sleep, a common feature of high need for recovery, separately predicts a growing waistline.
Preventa test: Waist-to-height ratio
Over time: Often sits underneath the other risks on this list.
Kidney function
Sustained high blood pressure and disturbed metabolism gradually affect how well the kidneys filter. Picking this up early makes it easy to act on.
Preventa test: Urine albumin-to-creatinine ratio
Over time: Develops slowly and is largely irreversible once present.
Overall work-related risk
The Work Experience score brings demands, resources and recovery together into one picture of how your work is affecting you. This is the assessment on this site.
Preventa test: Work Experience assessment
Over time: Long-term pressure without recovery, which also affects the risks above.
These risks build slowly and quietly, and they reinforce each other. Work stress is the one on this list you can usually change first.

None of these fix a badly designed job on their own. They do protect your recovery while the bigger conversation happens.
Protect recovery, not just rest
Recovery is anything that fully takes your attention off work — movement, people, hobbies. Scrolling in the evening usually does not count.
Treat sleep as the first step
A consistent sleep window does more for your tolerance of stress than any productivity change. Track it if that helps you see the pattern.
Make one boundary concrete
One clear rule beats good intentions: no messages after a set hour, a real lunch break, or one meeting-free block a day.
Move, even briefly
Short daily activity lowers the physical cost of stress. Consistency matters more than intensity.
Name the driver, not the feeling
Bring your manager a specific cause — workload, unclear priorities, no say in decisions — rather than a general sense of pressure. It is far easier to act on.
Involve your GP early
If symptoms persist, get them assessed. Early support shortens recovery considerably compared with waiting until you cannot work.
Tips for employers
Resilience training for individuals has a poor track record when the way the job is set up is the real problem. These are the changes that move the needle.
Measure before you programme
Find out which areas are actually under pressure — demands, control, support, reward, recovery, work-home — instead of buying a generic wellbeing offer.
Act on watch-level signals
The value of measuring is catching areas that are drifting, not confirming the ones already in trouble. Watch level is where action is cheapest.
Fix demands and control together
Where demands cannot fall, increase influence: over scheduling, prioritisation, and how the work is done.
Equip managers for the conversation
Most early signals reach a line manager first. Give them a simple script, a clear escalation route, and permission to adjust workload.
Design recovery into the week
Meeting-free blocks, realistic on-call rules, and an explicit norm about out-of-hours contact do more than a resilience workshop.
Keep reporting anonymous
People only answer honestly when they trust the reporting. Group-level results with privacy thresholds, never individual answers.
