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 (chemical, biological, and physical), they do not arise from a physical substance, object, or hazardous energy. [1]
Psychosocial hazards affect the psychological and physical well-being of workers, including their ability to participate in a work environment among other people. They cause not only psychiatric and psychological outcomes such as occupational burnout, anxiety disorders, and depression, but they can also cause physical injury or illness such as cardiovascular disease or musculoskeletal injury. Psychosocial risks are linked to the organization of work as well as workplace violence and are recognized internationally as major challenges to occupational safety and health as well as productivity. [1]
In general, workplace stress can be defined as an imbalance between the demands of a job, and the physical and mental resources available to cope with them. [2] Several models of workplace stress have been proposed, including imbalances between work demands and employee control, between effort and reward, and general focuses on wellness. [3]
Psychosocial hazards may be divided into those that arise from the content or the context of work. Work content includes the amount and pace of work, including both too much and too little to do; the extent, flexibility, and predictability of work hours; and the extent of employee control and participation in decision-making. Work context includes impacts on career development and wages, organizational culture, interpersonal relationships, and work–life balance. [3]
According to a survey by the European Agency for Safety and Health at Work, the most important psychosocial hazards—work stressors—are: [1]
Other psychosocial hazards are:
In addition, levels of noise or air quality that are considered acceptable from a physical or chemical hazard standpoint may still provide psychosocial hazards from being annoying, irritating, or causing fear of other health impacts from the environment. [3]
Psychosocial hazards are usually identified or assessed through inspecting how workers carry out work and interact with each other, having conversations with workers individually or in focus groups, using surveys, and reviewing records such as incident reports, workers' compensation claims, and worker absenteeism and turnover data. A more formal occupational risk assessment may be warranted if there is uncertainty about the hazards' potential severity, interactions, or the effectiveness of controls. [4]
There are several risk assessment survey tools for psychosocial hazards. [4] These include the NIOSH Worker Well-Being Questionnaire (WellBQ) from the U.S. National Institute for Occupational Safety and Health's Total Worker Health program, [5] the People at Work survey from Queensland Workplace Health and Safety, [6] the Copenhagen Psychosocial Questionnaire from the Danish National Research Centre for the Working Environment , [7] and the Management Standards Indicator Tool from the UK Health and Safety Executive. [8]
According to the hierarchy of hazard controls, the most effective controls are eliminating hazards, or if that is impractical, minimizing them, through good work design practices. These include measures to reduce overwork; providing workers with support, personal control, and clearly defined roles; and providing effective change management. [4]
In the context of psychosocial hazards, engineering controls are physical changes to the workplace that mitigate hazards or isolate workers from them. Engineering controls for psychosocial hazards include workplace design to affect the amount, type, and level of personal control of work, as well as access controls and alarms. The risk of workplace violence can be reduced through physical design of the workplace or by cameras. [3] Proper manual handling equipment, measures to reduce noise exposure, and appropriate lighting levels have a positive effect on psychosocial hazards, in addition to their effects to control physical hazard. [4]
Administrative controls include job rotation to reduce exposure time, clear policies on workplace bullying and sexual harassment, and proper consultation and training of employees. Personal protective equipment includes personal distress alarms, as well as equipment typically used for other types of hazards such as eye and face protection and hearing protection. [4]
Health promotion activities can improve workers' general and mental health, but should not be used as an alternative or substitute for directly managing risk from psychosocial hazards. [4] A recent Cochrane review—using moderate quality evidence—related that the addition of work-directed interventions for depressed workers receiving clinical interventions reduces the number of lost work days as compared to clinical interventions alone. [9] This review also demonstrated that the addition of cognitive behavioral therapy to primary or occupational care and the addition of a "structured telephone outreach and care management program" to usual care are both effective at reducing sick leave days. [9]
ISO 45003:2021 is an international standard developed by the International Organization for Standardization (ISO) allowing organizations to manage psychosocial risk at work, in particular, to be considered within occupational health and safety (OH&S) management systems based on ISO 45001 on Occupational Health and Safety Management System Standards. [10]
Exposure to psychosocial hazards in the workplace not only has the potential to produce psychological and physiological harm to individual employees, but can also produce further repercussions within society—reducing productivity in local/state economies, corroding familial/interpersonal relationships, and producing negative behavioral outcomes. [11] [12] Occupational burnout is a consequence of psychosocial hazards.
Occupational stress, anxiety, and depression can be directly correlated to psychosocial hazards in the workplace. [13]
Exposure to workplace psychosocial hazards has been strongly correlated with a wide spectrum of unhealthy behaviors such as physical inactivity, excessive alcohol and drug consumption, nutritional imbalance and sleep disturbances. [14] In 2003, a cross-sectional survey of 12,110 employees from 26 different workplace environments was established to examine the relationship between subjective workplace stress and healthy activity. The survey quantified the measurement of stress mainly through evaluation of an individual's perceived locus of control in the workplace (although other variables were also examined). The results concluded that self-reported high levels of stress were associated with, across both sexes: diets with a higher concentration of fat, less exercise, cigarette smoking (and increasing use), and less self-efficacy to control smoking habits. [15]
Supported by strong evidence from a plethora of meticulous cross-sectional and longitudinal studies, a link has been indicated between the psychosocial work environment and consequences on employees' physical health. Increasing evidence indicates that four main physiological systems are affected: hypertension and heart disease, wound healing, musculoskeletal disorders, gastrointestinal disorders, and impaired immunocompetence. [16] Additional disorders generally recognized as stress-induced include: bronchitis, coronary heart disease, mental illness, thyroid disorders, skin diseases, certain types of rheumatoid arthritis, obesity, tuberculosis, headaches and migraine, peptic ulcers and ulcerative colitis, and diabetes. [17]
Across the European Union, work-related stress alone affects over 40 million individuals, costing an estimated €20 billion a year in lost productivity. [18]
Ergophobia is described as an extreme and debilitating fear associated with work, a fear of finding or losing employment, or fear of specific tasks in the workplace. The term ergophobia comes from the Greek "ergon" (work) and "phobos" (fear).
Occupational noise is the amount of acoustic energy received by an employee's auditory system when they are working in the industry. Occupational noise, or industrial noise, is often a term used in occupational safety and health, as sustained exposure can cause permanent hearing damage. Occupational noise is considered an occupational hazard traditionally linked to loud industries such as ship-building, mining, railroad work, welding, and construction, but can be present in any workplace where hazardous noise is present.
Occupational hygiene or industrial hygiene (IH) is the anticipation, recognition, evaluation, control, and confirmation (ARECC) of protection from risks associated with exposures to hazards in, or arising from, the workplace that may result in injury, illness, impairment, or affect the well-being of workers and members of the community. These hazards or stressors are typically divided into the categories biological, chemical, physical, ergonomic and psychosocial. The risk of a health effect from a given stressor is a function of the hazard multiplied by the exposure to the individual or group. For chemicals, the hazard can be understood by the dose response profile most often based on toxicological studies or models. Occupational hygienists work closely with toxicologists (see Toxicology) for understanding chemical hazards, physicists (see Physics) for physical hazards, and physicians and microbiologists for biological hazards (see Microbiology, Tropical medicine, Infection). Environmental and occupational hygienists are considered experts in exposure science and exposure risk management. Depending on an individual's type of job, a hygienist will apply their exposure science expertise for the protection of workers, consumers and/or communities.
A waste collector, also known as a garbage man, garbage collector, trashman, binman or dustman, is a person employed by a public or private enterprise to collect and dispose of municipal solid waste (refuse) and recyclables from residential, commercial, industrial or other collection sites for further processing and waste disposal. Specialised waste collection vehicles featuring an array of automated functions are often deployed to assist waste collectors in reducing collection and transport time and for protection from exposure. Waste and recycling pickup work is physically demanding and usually exposes workers to an occupational hazard.
An occupational hazard is a hazard experienced in the workplace. This encompasses many types of hazards, including chemical hazards, biological hazards (biohazards), psychosocial hazards, and physical hazards. In the United States, the National Institute for Occupational Safety and Health (NIOSH) conduct workplace investigations and research addressing workplace health and safety hazards resulting in guidelines. The Occupational Safety and Health Administration (OSHA) establishes enforceable standards to prevent workplace injuries and illnesses. In the EU, a similar role is taken by EU-OSHA.
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, 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.
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 has not 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 by the WHO as a medical condition.
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.
A physical hazard is an agent, factor or circumstance that can cause harm with contact. They can be classified as type of occupational hazard or environmental hazard. Physical hazards include ergonomic hazards, radiation, heat and cold stress, vibration hazards, and noise hazards. Engineering controls are often used to mitigate physical hazards.
Positive psychology is defined as a method of building on what is good and what is already working instead of attempting to stimulate improvement by focusing on the weak links in an individual, a group, or in this case, a company. Implementing positive psychology in the workplace means creating an environment that is more enjoyable, productive, and values individual employees. This also means creating a work schedule that does not lead to emotional and physical distress.
Occupational health nursing is a specialty nursing practice that provides for and delivers health and safety programs and services to workers, worker populations, and community groups. The practice focuses on promotion, maintenance and restoration of health, prevention of illness and injury, and protection from work‐related and environmental hazards. Occupational health nurses (OHNs) aim to combine knowledge of health and business to balance safe and healthful work environments and a "healthy" bottom line.
Occupational safety and health (OSH) or occupational health and safety (OHS) is a multidisciplinary field concerned with the safety, health, and welfare of people at work. OSH is related to the fields of occupational medicine and occupational hygiene and aligns with workplace health promotion initiatives. OSH also protects all the general public who may be affected by the occupational environment.
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, arrhythmia, 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.
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. Stresses at work can be eustress, a positive type of stress, or distress, a negative type of stress. 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.
Ergonomic hazards are physical conditions that may pose a risk of injury to the musculoskeletal system due to poor ergonomics. These hazards include awkward or static postures, high forces, repetitive motion, or short intervals between activities. The risk of injury is often magnified when multiple factors are present.
Engineering controls are strategies designed to protect workers from hazardous conditions by placing a barrier between the worker and the hazard or by removing a hazardous substance through air ventilation. Engineering controls involve a physical change to the workplace itself, rather than relying on workers' behavior or requiring workers to wear protective clothing.
Workplace robotics safety is an aspect of occupational safety and health when robots are used in the workplace. This includes traditional industrial robots as well as emerging technologies such as drone aircraft and wearable robotic exoskeletons. Types of accidents include collisions, crushing, and injuries from mechanical parts. Hazard controls include physical barriers, good work practices, and proper maintenance.
The impact of artificial intelligence on workers includes both applications to improve worker safety and health, and potential hazards that must be controlled.
Psychosocial safety climate (PSC) is a term used in organisational psychology that refers to the shared belief held by workers that their psychological health and safety is protected and supported by senior management. PSC builds on other work stress theories and concerns the corporate climate for worker psychological health and safety. Studies have found that a favourable PSC is associated with low rates of absenteeism and high productivity, while a poor climate is linked to high levels of workplace stress and job dissatisfaction. PSC can be promoted by organisational practices, policies and procedures that prioritise the psychosocial safety and wellbeing of workers. The theory has implications for the design of workplaces for the best possible outcomes for both workers and management.
