Selected Classic Research Studies
Recommended work organization intervention studies
The following research articles are a small sample (not a systematic review) of scientific intervention studies that have addressed a number of work stressors in significant ways and cover a range of different occupations from several countries. In the future, the HWC is developing a comprehensive, searchable database of this extensive research literature as well as a summary of this evidence, so we can more completely recommend “best-practices” in addressing work stressors in your particular industry or organization.

Glossary of Terms
Absenteeism – The rate of “unscheduled absences” in the workplace, when employees do not arrive for work as scheduled. Absenteeism can result from work stress and illness as well as family and personal issues. Replacement of absent workers can increases costs and lower profits because it reduces productivity and often work quality.
Coworker Support – Working alone can be a significant source of distress. People need social interaction to remain healthy. Having coworkers who are unfriendly, competitive and who do not work well together is a serious source of stress at work and one that can be promoted by toxic work practices and cultures from the top levels of an organization.
Effort-reward imbalance – is a commonly studied psychosocial work stressor model developed by Johannes Siegrist. It is the idea that it is a stressful experience when you put in a high level of effort as a requirement of the job, and it is not matched with an appropriate level of reward (including fair pay, promotion prospects and recognition). ERI is related to poor mental health, including depression, adverse health behaviors, and heart disease.
High Demands – Having work that is too highly demanding means not having enough time to complete your tasks in a regular workday; having unrealistic deadlines; getting constantly interrupted; dealing with conflicting demands from multiple coworkers or managers; also, when the pace at which you are required to produce a widget, a report, serve a customer or other output is too fast to manage. These all result from how work is organized.
Job control (decision latitude) – When workers are not given some say over how they complete their work tasks, when they find every step “micro-managed” by supervisors, or every keystroke or interaction with customers monitored or scripted, workers lose a sense of autonomy. They have “low job control” which has been shown in many research studies to be significantly related to poor mental and physical health, including depression, high blood pressure and heart disease.
Job Insecurity – In a free market economy, such as the U.S., private sector companies have a lot of flexibility in hiring and firing. Restructuring, downsizing, and outsourcing causing layoffs have become all too common. Job loss is a reality that gives many workers a feeling that they may be next. Job insecurity is a perceived sense or the objective reality that you might lose your job at any time and it is related to a higher risk of depression and CVD.
Job Strain – is one of the most commonly studied psychosocial work stressor models and was developed by Robert Karasek (1990). It is having a job that has a combination of high demands (workload) and low job control and is related to burnout, depression, health behaviors (smoking, alcohol), obesity, high blood pressure, diabetes, and heart disease.
Lack of Promotion Opportunities – When you are stuck in a “dead-end” job, where you have a sense that there is no way forward or to advance your career, or to be given appropriate pay raises, this is a significant stressor. As we gain experience and skill in a job, a lack of appropriate rewards including recognition and promotion opportunities, can be especially stressful and is an aspect of effort-reward imbalance.
Lack of health insurance – Part-time workers, workers with non-standard employment arrangements (independent contractors) often don’t have access to employer group health plans. A lack of access to health insurance means you are less likely to get treated for a chronic illness in time to prevent more serious complications and have a higher mortality.
Long work hours – Americans work more hours annually than any other high-income, industrialized country. Over 25% of full-time salaried employees report working more than 55 hours per week. Mandatory overtime has become more common. Long work hours increase the risk for sleep disruption, depression and heart disease and are also associated with greater work-family conflict.
Low rewards – Inadequate pay threatens the economic security and the health and well-being of workers and their families. With a Federal minimum wage of $7.25/hour, the U.S. is ranked 12th in minimum wage, behind Australia, UK, Canada, Japan and most of Europe, just in front of Slovenia (13th). Low-wage jobs in retail and health care are the fastest growing sector of the U.S. economy.
Organizational Justice – When workers report that their organizations or supervisors treat them fairly (relational justice), and that decision-making procedures and outcomes are fair (procedural justice), they are much less likely to develop illnesses including depression, have less sleeping problems, greater cognitive abilities, better cardiovascular health and are less likely to be absent or leave the job.
Presenteeism – is a term describing how workers who come to work when ill, injured or experiencing chronic health problems, may, as a consequence, have lower productivity. Also called LPT or LWPT (lost [work] productive time), it includes: time not on task, decreased work quality and/or quantity. Data suggests that presenteeism may be more costly to employers than either absenteeism or short-term disability.
Repetitive work – It has been known for some time that monotonous, routine jobs that provide no variety – such as assembly-line work, data-entry, monitoring, etc. – can be at best “boring” but can also lead to repetitive motion injuries, burnout, and depression.
Shift work – Working nights or rotating shifts, common in many 24-hour industries, can disrupt sleep, family life, exercise and eating behaviors and has shown to increase the risk for CVD and mortality.
Sick/family leave and vacation time – More than 43 million workers, especially low-wage workers, do not have any paid sick leave or family leave benefits. Many workers who have to decide between an even lower paycheck and going to work sick, choose to go to work. 1 in 4 Americans in the private sector do not have any paid vacation time and many more don’t take their paid vacation.
Skill discretion – simply means that the job provides some creativity, and the opportunity to learn a variety of things or helps to develop and use your special skills or abilities. If your job is “low” in skill discretion, this means you have less opportunities to learn new things or practice a variety of tasks. It is a part of job control.
Supervisor support – At some time in our work careers we have experienced a “bad boss,” someone who yells or belittles you and your coworkers or someone that is willing to “throw you under the bus” rather than work together as a team. A lack of “support” from supervisors – not just emotionally but in terms of appropriate feedback and help with completing tasks – is a significant source of stress at work leading to poor health.
Work-family conflict – You come home too tired after work to do the things you enjoy. You have so much work that it takes time away from being with family or friends or personal interests. When your work role interferes with your role in the family or personal life, this is called work-family conflict. Studies have shown that it can negatively affect productivity as well as lead to burnout and depression. Work-life balance has been a growing concern in the United States where 38% of employees do not have paid sick/family leave and 23% have no paid vacation time.
Workplace sexual harassment – while there is not a universal definition of sexual harassment, it is behavior that occurs in the workplace; occurs because of a person’s sex and is related to or about sex; is unwelcome, unwanted, uninvited; and can affect the terms or conditions of employment or create a hostile work environment. It is illegal in the U.S., but at least 1 in 3 American women have been the victim of workplace sexual harassment. It can result in mental health challenges and job turnover.
Workplace discrimination violates the Civil Rights Act (1964) because of hostile behaviors or policies that intentionally or unintentionally target individuals due to their gender, race, religion, national origin, sexual orientation, disability or age. Yet while discrimination practices are down in the U.S., they continue to be surprisingly widespread.
Workplace bullying is “repeated mistreatment or abusive conduct that is threatening, humiliating, or intimidating.” (WorkplaceBullying.org) Almost 20% of Americans report experiencing bullying at work. Sixty million Americans are aware of and affected by bullying in their workplace and 40% of those bullied develop serious health problems. Women and minorities are more likely to be targeted. It is illegal in 31 states.
