Burnout Explained: Signs, Symptoms and What's Causing It

Workplace burnout has become one of the defining wellbeing challenges of the modern workplace. Once dismissed by some as little more than a corporate buzzword, burnout is now recognised as a serious occupational issue with significant consequences for employees, organisations, and productivity. As workloads intensify and the boundaries between work and personal life continue to blur, prioritising employee wellbeing has never been more important.

The evidence is difficult to ignore. According to a 2024 study by Indeed, more than half (52%) of UK employees report feeling burned out, with 67% saying their symptoms have worsened since the pandemic. Similarly, Deloitte UK's research found that 63% of employees experienced at least one characteristic of burnout- an increase of 51% compared with two years earlier.  

The message is clear: burnout is not a passing trend or workplace cliché. It is a growing threat to employee health, wellbeing, and organisational performance. Understanding what burnout is, recognising the warning signs, and taking proactive steps to prevent it are essential for creating healthier, more resilient workplaces.

What is burnout?

Burnout is defined is a state of significant mental, physical and emotional exhaustion caused by chronic and unmanaged stress. Whilst burnout is typically caused by stress, the two are not the same.  

Stress is often short term and whilst it may impact your energy and emotions, it does not typically prevent individuals from engaging in day-to-day activities. Conversely, burnout often leads individuals to feel detached, demotivated and exhausted to the point that even routine tasks can feel overwhelming.  

One of the most challenging parts of burnout, is that it can often creep up on us. It can begin with feeling overwhelmed but assuming that these feelings will improve once the busy period has passed. Recognising the warning signs is one of the most important steps in protecting your wellbeing.

Physical Symptoms:

  • Feeling exhausted most of the time
  • Struggling to sleep
  • Headaches
  • Nausea or lack of appetite
  • Frequent illness due to lowered immune function

Emotional Symptoms:

  • Feeling trapped or defeated
  • Self-doubt and self-criticism
  • Feeling detached from things that used to bring pleasure
  • Feeling demotivated and/or cynical
  • Lacking a sense of achievement
  • Persistent worry and/or anxiety

Behavioural Symptoms:

  • Procrastination
  • Difficulty concentrating
  • Decreased productivity
  • Withdrawing from people, responsibilities and/or activities
  • Reliance on food, alcohol and/or drugs to cope
    Feeling irritable or angry
  • High absenteeism at work

What really causes burnout?

Burnout isn’t a case of a singular bad day or an isolated event. Instead, it usually develops over time through a combination of prolonged pressure, workplace demands and limited resources to manage increasing stressors.   

Renowned burnout researcher Dr Christina Maslach, there are 6 primary factors that may place someone at an increased risk of burnout. It’s important to remember that the below factors do not guarantee that someone will experience burnout. Similarly, you don’t need to identify with all 6 factors to feel burned out. Everyone experiences pressure differently and if any of these factors feel familiar over a prolonged period of time, it may be worthwhile to reflect on what support or resources may help you to support your wellbeing.

The 6 Leading Contributors to Burnout:

1.) Workload

It is perhaps not surprising that workload is one of the greatest contributors to burnout. Importantly, workload risk does not refer to an occasional burst of increased work. Instead, risk increases when workplace demands continuously exceed an individual’s resources for coping with them. This may include long hours, tight deadlines, juggling multiple responsibilities at once or unrealistic workload expectations. Over time, this level of stress becomes unsustainable, leading to physical and mental exhaustion.


2.) Lack of Control

It’s not just how much you work that contributes to burnout, but your ability to take control of it. Dr Maslach found that individuals who had high workloads, but also had high levels of autonomy for managing that work, were less likely to experience burnout. Conversely, those with little flexibility often felt that workload was unmanageable.


3.) Lack of Recognition or Reward

When you’re working incredibly hard, sometimes it’s not just about the volume of work, but also whether others see and value your contributions. When individuals don’t receive recognition for hard work or don’t feel supported by colleagues, it can lead to a sense of futility and disengagement, which are hallmarks of burnout.


4.) Relationships

Full-time workers spend 36% of their waking hours at work each week. It’s therefore not surprising that the people we are surrounded by during that time can have a huge impact on wellbeing. According to Maslach, “"People thrive in community and function best when they share praise, comfort, happiness, and humor with people they like and respect. In addition to emotional exchange and instrumental assistance, this kind of social support reaffirms a person's membership in a group with a shared sense of values."


5.) Lack of Fairness

When work processes and systems don’t feel fair, it can lead to feeling disrespected and powerless within the workplace. There are a number of situations that can lead to a perceived lack of fairness, including:

·       Inequity in workload or pay

·       Cheating in the workplace

·       Inappropriate handling of promotions or evaluations

·       Poor dispute resolution procedures


6.) Values

The last factor Maslach identified is when an individual’s values do not correspond to the values of their employer. For example, someone may pursue a career in research due to a value on advancing science. Yet upon starting, they find that their management’s focus is primarily on securing funding, not on the research itself. Alternatively, value mismatches can occur when an individual chooses a job in the knowledge that it does not align with their values. For example, someone may strongly value animal welfare yet choose to work for a cosmetics company that tests their products on animals. Whilst they initially accepted the role for its competitive salary, value misalignment may prove draining and demoralising over time.


Burnout is not a personal failure

If you’ve recognised several of the symptoms or risk factors discussed in this article, it is important to remember that burnout is not a sign of failure nor a sign that you are not resilient enough. It is an understandable consequence to prolonged stress that has gone unaddressed.  

Recognising the impact of burnout is an important first step towards recovery. By understanding what contributes to burnout, you can begin to identify where changes or additional support may be needed to protect your wellbeing.
