Work-Related Mental Disorders: What are the main ones?

---

In recent years, increasing pressure in the workplace has led to a significant increase in cases of work-related mental disorders.

What was once considered a natural part of professional life, such as stress and overload, is now understood as a serious public health problem.

Workers in all sectors are exposed to stressful factors, such as excessive demand, lack of recognition and professional insecurity, which can lead to the development of illnesses such as Burnout Syndrome, anxiety and depression.

These mental disorders not only affect workers’ health, but also directly impact companies’ productivity and results.

According to World Health Organization (WHO), stress and other work-related disorders are responsible for global economic losses exceeding 1 trillion dollars annually, due to decreased productivity and prolonged absences.

But what are the main work-related mental disorders? How do they affect workers and what can be done to prevent them? Let’s explore these questions in detail.

1. Occupational Stress

Stress in the workplace is, without a doubt, the most common disorder among professionals.

It occurs when work demands exceed the individual's ability to respond, leading to emotional and physical overload.

According to American Psychological Association (APA), approximately 751% of workers report experiencing moderate to high levels of work-related stress at some point in their careers.

Occupational stress can be triggered by a variety of factors, including tight deadlines, unattainable goals, lack of control over tasks, poor communication with superiors, and lack of recognition.

Over time, this chronic stress can develop into more serious disorders, such as anxiety and depression, in addition to compromising the quality of sleep and causing physical health problems, such as high blood pressure.

Below is a table illustrating the prevalence of some work-related mental disorders and their main causes:

Disorder	Main Symptoms	Common Causes	Global Prevalence
Occupational Stress	Exhaustion, irritability, insomnia	Overload, lack of autonomy	30% (ILO, 2022)
Burnout	Extreme fatigue, cynicism, low achievement	Overwork, lack of recognition	13% (WHO, 2023)
Generalized Anxiety	Excessive worry, restlessness, muscle tension	Pressure for results, competitive environment	18% (NIH, 2023)

The impact of occupational stress is not limited to employee well-being.

Companies with high levels of stress among employees suffer from increased turnover rates, absenteeism and reduced quality of work.

To combat these effects, organizations are investing in well-being programs, such as time management training, mindfulness initiatives and more flexible work environments.

2. Burnout syndrome

A Burnout Syndrome, also known as burnout, is a disorder that arises after long periods of chronic stress at work.

Officially recognized by World Health Organization in 2019 as a work-related phenomenon, Burnout is characterized by three main symptoms: emotional exhaustion, detachment from work and a feeling of low achievement.

Around 131,000% of the world's working population has already been diagnosed with Burnout, and this number is likely to grow, especially in sectors with high emotional demands, such as healthcare, education and financial services.

Among the factors that lead to Burnout are work overload, lack of recognition and lack of support from superiors.

These factors can lead to profound demotivation and even physical health problems, such as heart and immune disorders.

“Inadequate stress management in the workplace has been identified as one of the main causes of the increase in Burnout diagnoses, directly affecting workers’ quality of life and companies’ productivity.” — WHO Occupational Health Report, 2023.

O WHO Report also highlights that Burnout is one of the main reasons for workers leaving in countries such as the United States and Japan.

Preventive measures, such as reducing working hours, promoting a more collaborative work environment and strengthening communication between leaders and their teams, are essential to reducing cases of Burnout.

3. Generalized Anxiety

Generalized anxiety is another mental disorder that affects millions of workers around the world.

This disorder manifests itself as a constant and disproportionate concern about everyday situations, leading to symptoms such as muscle tension, agitation, difficulty concentrating and irritability.

In the workplace, anxiety is often associated with pressure for results, job insecurity and competitive environments.

According to the National Institute of Mental Health (NIH), 181,000 U.S. workers suffer from some type of anxiety disorder, and most of them report that their work environment contributes to worsening symptoms.

Anxiety at work can lead to a significant decrease in productivity and, in more severe cases, can result in prolonged absences from work.

Companies that implement mental health policies, such as creating decompression spaces and offering occupational therapy sessions, can help reduce anxiety levels among employees.

Adopting practices such as flexible working hours is also an effective measure to combat the impact of anxiety.

4. Work-Related Depression

Work-related depression is a serious disorder that often goes unnoticed.

Unlike stress and anxiety, depression can be more difficult to diagnose, as its symptoms include persistent sadness, disinterest in daily activities, feelings of worthlessness, and extreme fatigue.

However, studies show that the work environment can be an important trigger for the development of depression.

According to International Labour Organization (ILO), around 151,000 workers globally suffer from depression to some degree, with many developing the disorder as a direct consequence of unhealthy working conditions, such as bullying, job insecurity and lack of emotional support.

Depression is the main cause of absence from work in several countries, including Brazil, where the number of workers absent due to depression has increased by 30% in the last five years, according to data from the INSS.

Preventive Measures for Work-Related Mental Disorders

Given the growing prevalence of work-related mental disorders, it is crucial to adopt preventive measures that protect the mental health of workers.

Among the main prevention strategies are:

1. Promoting Work-Life Balance: Encouraging policies that allow workers to balance their personal lives with the demands of work is one of the most effective ways to reduce stress and burnout. This can include offering flexible hours, working from home, and promoting regular breaks during the workday.
2. Healthy Work Environments: Creating collaborative work environments where employees feel valued and recognized for their efforts contributes significantly to the prevention of disorders such as burnout syndrome and anxiety. Companies that invest in clear communication between leaders and teams, as well as in training for managers, see reductions in stress levels and improvements in overall mental health.
3. Psychological Support at Work: The implementation of psychological support programs is one of the main recommendations of the WHO for promoting mental health in companies. These programs can include psychological care, occupational therapy sessions and well-being activities, such as meditation and yoga. Studies show that companies that offer psychological support see a reduction of up to 40% in cases of absence due to mental disorders.

Conclusion

You work-related mental disorders are a growing challenge for businesses and workers around the world.

Stress, Burnout Syndrome, anxiety and depression not only affect the health and quality of life of individuals, but also generate significant economic losses for organizations.

However, by adopting preventive practices, such as promoting healthy work environments, offering psychological support and valuing the balance between personal and professional life, it is possible to minimize the impacts of these disorders.

Investing in the mental health of workers is not only a matter of social responsibility, but also a smart business strategy, resulting in greater productivity, lower absenteeism rates and, consequently, better results for companies.
