Job strain is a form of psychosocial stress that occurs in the workplace. One of the most common forms of stress, it is characterized by a combination of low salaries, high demands, and low levels of control over things such as raises and paid time off. [1] Stresses at work can be eustress, a positive type of stress, or distress, a negative type of stress. [2] Job strain in the workplace has proved to result in poor psychological health, and eventually physical health. Job strain has been a recurring issue for years and affects men and women differently. [3]
Examples of positive causes of stress in the workplace include starting a new job and receiving a raise. Both of these situations improve performance. [2]
On the negative side, one cause of job strain is low salaries. [4] Low pay causes job strain due to living expenses. Housing expenses are extremely high, which makes it difficult for minimum wage workers to afford housing. As the minimum wage increases, the cost of living increases as well. [5]
The second cause of job strain comes from excessive workloads. Being exhausted from overworking is a common stressor in the workplace and can often lead to poor communication between coworkers. [6] A 2019 survey by Cartridge People identified workload as the main cause of occupational stress. [7]
A lack of support from employers and employees may also cause stress. Making decisions and participating is a way of support from employers and employees. [8]
When experiencing job strain in the form of distress at work, people are subject to headaches, stomachaches, sleep disturbances, short temper, and difficulty concentrating. Anxiety, insomnia, high blood pressure, a weakened immune system, and heart disease may occur if stress at work becomes more persistent. [4] A 2012 meta-analysis found a positive association between job strain and coronary heart disease risk. [1] A 2015 meta-analysis found a similar association between job strain and stroke; the association was especially strong for women. [9] Time poverty has been found to heighten the risk for depression, inflated BMI, and cardiovascular disease in women. [10] Job strain has been found to increase the risk of higher blood pressure, [11] but not obesity. [12]
Men and women react differently when exposed to work situations involving stress. A survey was taken by Canadian Community Health in 2012 that showed women experience higher job strain than men. It also showed that women feel they have lower levels of control, yet experience more coworker support, than men. [13] Because women have lower levels of control at work, they experience more mental health risks such as depression and anxiety. Men tend to suffer from physical risks such as heart disease from carrying higher roles at work.
A 2022 study by McKinsey & Company concluded that women are 41% more likely to be subjected to a toxic workplace culture and that their risk of burnout is elevated. [14] [15]
A 2021 WHO study concluded that working 55+ hours a week raises the risk of stroke by 35% and the risk of dying from heart conditions by 17%, when compared to a 35-40 hour week. [16]

Karoshi, which can be translated into "overwork death", is a Japanese term relating to occupation-related sudden death.
Cardiovascular disease (CVD) is any disease involving the heart or blood vessels. CVDs constitute a class of diseases that includes: coronary artery diseases, heart failure, hypertensive heart disease, rheumatic heart disease, cardiomyopathy, arrhythmia, congenital heart disease, valvular heart disease, carditis, aortic aneurysms, peripheral artery disease, thromboembolic disease, and venous thrombosis.
An occupational disease or industrial disease is any chronic ailment that occurs as a result of work or occupational activity. It is an aspect of occupational safety and health. An occupational disease is typically identified when it is shown that it is more prevalent in a given body of workers than in the general population, or in other worker populations. The first such disease to be recognised, squamous-cell carcinoma of the scrotum, was identified in chimney sweep boys by Sir Percival Pott in 1775. Occupational hazards that are of a traumatic nature are not considered to be occupational diseases.
Health promotion is, as stated in the 1986 World Health Organization (WHO) Ottawa Charter for Health Promotion, the "process of enabling people to increase control over, and to improve their health."
The term eustress means "beneficial stress"—either psychological, physical, or biochemical/radiological (hormesis).
Musculoskeletal disorders (MSDs) are injuries or pain in the human musculoskeletal system, including the joints, ligaments, muscles, nerves, tendons, and structures that support limbs, neck and back. MSDs can arise from a sudden exertion, or they can arise from making the same motions repeatedly repetitive strain, or from repeated exposure to force, vibration, or awkward posture. Injuries and pain in the musculoskeletal system caused by acute traumatic events like a car accident or fall are not considered musculoskeletal disorders. MSDs can affect many different parts of the body including upper and lower back, neck, shoulders and extremities. Examples of MSDs include carpal tunnel syndrome, epicondylitis, tendinitis, back pain, tension neck syndrome, and hand-arm vibration syndrome.
Technostress has been defined as the negative psychological relationship between people and the introduction of new technologies. Where ergonomics is the study of how humans react to and physically fit into machines in their environment, technostress is a result of altered behaviors brought about by the use of modern technologies at office and home environments.
An occupational exposure limit is an upper limit on the acceptable concentration of a hazardous substance in workplace air for a particular material or class of materials. It is typically set by competent national authorities and enforced by legislation to protect occupational safety and health. It is an important tool in risk assessment and in the management of activities involving handling of dangerous substances. There are many dangerous substances for which there are no formal occupational exposure limits. In these cases, hazard banding or control banding strategies can be used to ensure safe handling.
Occupational health psychology (OHP) is an interdisciplinary area of psychology that is concerned with the health and safety of workers. OHP addresses a number of major topic areas including the impact of occupational stressors on physical and mental health, the impact of involuntary unemployment on physical and mental health, work-family balance, workplace violence and other forms of mistreatment, psychosocial workplace factors that affect accident risk and safety, and interventions designed to improve and/or protect worker health. Although OHP emerged from two distinct disciplines within applied psychology, namely, health psychology and industrial and organizational psychology, for a long time the psychology establishment, including leaders of industrial/organizational psychology, rarely dealt with occupational stress and employee health, creating a need for the emergence of OHP. OHP has also been informed by other disciplines, including occupational medicine, sociology, industrial engineering, and economics, as well as preventive medicine and public health. OHP is thus concerned with the relationship of psychosocial workplace factors to the development, maintenance, and promotion of workers' health and that of their families. The World Health Organization and the International Labour Organization estimate that exposure to long working hours causes an estimated 745,000 workers to die from ischemic heart disease and stroke in 2016, mediated by occupational stress.
The ICD-11 of the World Health Organization (WHO) describes occupational burnout as an occupational phenomenon resulting from chronic workplace stress that hasn't been successfully managed, with symptoms characterized by "feelings of energy depletion or exhaustion; increased mental distance from one’s job, or feelings of negativism or cynicism related to one's job; and reduced professional efficacy." It is classified as a mismatch between the challenges of work and a person's mental and physical resources, but is not recognized as a standalone medical condition, apart from the diagnosis of exhaustion disorder, which is only used in Sweden.
Occupational stress is psychological stress related to one's job. Occupational stress refers to a chronic condition. Occupational stress can be managed by understanding what the stressful conditions at work are and taking steps to remediate those conditions. Occupational stress can occur when workers do not feel supported by supervisors or coworkers, feel as if they have little control over the work they perform, or find that their efforts on the job are incommensurate with the job's rewards. Occupational stress is a concern for both employees and employers because stressful job conditions are related to employees' emotional well-being, physical health, and job performance. The World Health Organization and the International Labour Organization conducted a study. The results showed that exposure to long working hours, operates through increased psycho-social occupational stress. It is the occupational risk factor with the largest attributable burden of disease, according to these official estimates causing an estimated 745,000 workers to die from ischemic heart disease and stroke events in 2016.
Workplace health promotion is the combined efforts of employers, employees, and society to improve the mental and physical health and well-being of people at work. The term workplace health promotion denotes a comprehensive analysis and design of human and organizational work levels with the strategic aim of developing and improving health resources in an enterprise. The World Health Organization has prioritized the workplace as a setting for health promotion because of the large potential audience and influence on all spheres of a person's life. The Luxembourg Declaration provides that health and well-being of employees at work can be achieved through a combination of:
Metabolically healthy obesity (MHO) is a disputed medical condition characterized by obesity which does not produce metabolic complications.
A psychosocial hazard or work stressor is any occupational hazard related to the way work is designed, organized and managed, as well as the economic and social contexts of work. Unlike the other three categories of occupational hazard, they do not arise from a physical substance, object, or hazardous energy.
Occupational heat stress is the net load to which a worker is exposed from the combined contributions of metabolic heat, environmental factors, and clothing worn, which results in an increase in heat storage in the body. Heat stress can result in heat-related illnesses, such as heat stroke, hyperthermia, heat exhaustion, heat cramps, heat rashes, and chronic kidney disease (CKD). Although heat exhaustion is less severe, heat stroke is a medical emergency and requires emergency treatment, which if not provided, can lead to death.
Occupational cardiovascular diseases (CVD) are diseases of the heart or blood vessels caused by working conditions, making them a form of occupational illness. These diseases include coronary heart disease, stroke, cardiomyopathy, arrythmia, and heart valve or heart chamber problems. Cardiovascular disease is the leading cause of death in the United States and worldwide. In the United States, cardiovascular diseases account for one out of four deaths. The 6th International Conference on Work Environment and Cardiovascular Diseases found that within the working age population about 10-20% of cardiovascular disease deaths can be attributed to work. Ten workplace stressors and risk factors were estimated to be associated with 120,000 U.S. deaths each year and account for 5-8% of health care costs.
Employees who work overtime hours experience numerous mental, physical, and social effects. In a landmark study, the World Health Organization and the International Labour Organization estimated that over 745,000 people died from ischemic heart disease or stroke in 2016 as a result of having worked 55 hours or more per week. Significant effects include stress, lack of free time, poor work-life balance, and health risks. Employee performance levels could also be lowered. Long work hours could lead to tiredness, fatigue, and lack of attentiveness. As a result, suggestions have been proposed for risk mitigation.
Sleep is a naturally recurring state of mind and body, characterized by altered consciousness, relatively inhibited sensory activity, reduced muscle activity, and inhibition of nearly all voluntary muscles during rapid eye movement (REM) sleep, and reduced interactions with surroundings. An essential aspect of sleep is that it provides the human body with a period of reduced functioning that allows for the systems throughout the body to be repaired. This time allows for the body to recharge and return to a phase of optimal functioning. It is recommended that adults get 7 to 9 hours of sleep each night. Sleep is regulated by an internal process known as the circadian rhythm. This 24-hour cycle regulates periods of alertness and tiredness that an individual experiences. The correlation between psychological stress and sleep is complex and not fully understood. In fact, many studies have found a bidirectional relationship between stress and sleep. This means that sleep quality can affect stress levels, and stress levels can affect sleep quality. Sleep change depends on the type of stressor, sleep perception, related psychiatric conditions, environmental factors, and physiological limits.

Overwork, also known as excessive work or work overload, is an occupational condition characterized by working excessively, frequently at the expense of the worker's physical and mental health. It includes working beyond one's capacity, leading to fatigue, stress, and potential health complications.
