Organization of Presentation
• 1. Dimensions of work stress; meta analyses of effect of work stress on physical and mental health; prevalence of work related suicide using NVDRS; interventions.
• 2. Qualitative research: Case studies from Detroit Suicide Project on 3 subtypes– job demotion, toxic coworkers, bullying.
• 3. Quantitative research: 6 case/control studies. • 4. Suicide by occupation and industry as clues to
distribution of deadly work stress. • 5. Suggestions for future research.
Dimensions of Work Stress
• Job Strain (involves tasks of a job) – Job Control (incl. skill level) – Job demands (e.g., workload, fast pace)
• Low Social Support: from coworkers, supervisors – Incl. individual bullying, discrimination, sexual harassment
• Organizational (In)Justice – Distributive Justice (or “Effort-Reward Imbalance (ERI)”are rewards fair?) – Procedural Justice (do rules apply equally to all) – Relational Justice (fair/cordial worker-supervisor relationships)
• Incl. organizational bullying, reprisals against whistle blowers • Loss/failure (e.g., unemployment, demotion, poor performance reviews) • Other: e.g., work related injuries, court proceedings • Karasek, R.A. 1979.

Significance: Numbers of Suicides, Mentally Troubled Workers, & Interventions
• A significant number of suicides are located at work. • Between 1995-2001, 1,730 suicides took place at work. Accounted
for 31% of all deaths at work. • Between 2003-2010 1,804 suicides took place at the workplace, or
38% of all deaths at work. • 6.4% of workers suffer from major depression & 1.1% bipolar
disorder (National Comorbidity Survey) • Average age of an American suicide is 44, mid life working age. • While there have been many interventions to reduce workplace
stress, there is little or no data on their effectiveness (Germain, 2014: 151).
• Germain, G. 2014. Work-related suicide. An analysis of U.S. Government reports and recommendations for human resources. Employee Relations, 36(2):148-164.
SIGNIFICANCE: Work Stress (Effort/Reward Imbalance) and Heart Disease, Mental Illness
• Heart Disease. Meta analysis of 14 prospective studies determined that, on average, the adjusted risk ratio for a combination of high effort/low rewards at work was 1.58 (Kivimaki et al., 2006). (ERI strongest predictor)
• Mental Disorders (e.g., depression). Meta analysis of 11 studies high effort/low reward work stress increased relative risk for mental disorders by 1.84 (Stansfeld et al., 2006). (ERI strongest predictor)
• Sample ERI item: “Considering all my efforts & achievements, I receive the respect & prestige I deserve at work”

Prevalence of Work Stress Related Suicides: NVDRS 11%
• An analysis of 30,000 suicides in the National Violent Death Reporting System (NVDRS) determined that at least 11% are related to “job problems” (Stack & Bowman, 2012)
• Job problems refer to issues at work which contributed to the suicide. These include: – tensions with a coworker, – poor performance reviews, – increased pressure, – fear of layoffs, & unemployment.
• 11% is likely an underestimate since the NVDRS is simply based on the data received from the county level. CDC coders can input only what they receive from local county medical examiners & coroners. In some cases work related strains can play a part in suicide, but if they are not mentioned/coded during local investigations, they go unrecorded. There is no standard protocol used nation wide for coding economic factors in cause of death certification at the local level.
• In Australia, a study determined that 17% (642/3775) suicides were work related (Routley, 2012) • Stack, S. & B. Bowman. 2012. Suicide Movies: Social Patterns, 1900-2009. Cambridge, Ma.: Hogrefe. Routley, et al.

Qualitative Work-- Detroit Suicide Project
• Job Demotion • Conflict with Coworkers • Worker (bully perpetrator) – supervisor conflict
Case Study: Job Demotion followed by Suicide Detroit Suicide Project
Detroit Suicide Project, ongoing analysis of 1,400 case files
Combination of Strains: Loss, Effort/Reward Imbalance, & Procedural Justice. • Ms. Smith, age 50, was called into her
boss’s office. To her surprise, she was notified that she was being demoted at her position with the company.
• Ms. Smith finished her work that day and left for home at 5 PM.
• She drove home and opened her garage with her remote control. She closed the door behind her and kept the engine running. She died of CO poisoning.

Conflict between Co-workers & Suicide-- Case of the Steakhouse Slashers: Detroit Suicide Project
• Two workers in a steakhouse had a history of conflict. One night they attacked each other with knives. One required 120 stitches from wounds inflicted by his adversary. Subsequently, the employer fired both of them. Shortly thereafter the victor in the fight took his own life.
• Stack, S & Wasserman, I. 2007. Economic strain & suicide risk: A qualitative analysis. Suicide & Life Threatening Behavior, 37, 103-112.
Conflict Between a Bullying Perpetrator (Worker) and his Supervisor: Detroit Suicide Project
• A 35 year old white, single male had frequent altercations with his female supervisor at a large automotive factory. His coworkers had teased him and taunted him about it. Conflicts escalated until the man was “written up” by his female supervisor placed on temporary layoff. Shortly thereafter he suicided by firearm.
• Stack, S & Wasserman, I. 2007. Economic strain & suicide risk. A qualitative analysis. Suicide & Life Threatening Behavior, 37, 103-112.
Quantitative Work • Searched Medline, Soc Abstracts, for studies on
– death by suicide (suicide ideation, attempts omitted) – with a control group with which to compare the
suicides (descriptive studies on suicides only omitted) – with at least one measure of work stress
• 6 studies met the criteria • Findings mixed. Strongest findings are for one study of job
demotion & suicide. No studies on ERI .

Job Demotion as a Work Stress Factor: Nat’l Mortality Followback Survey
• The second American NMFBS did measure two work stress constructs: unemployment and job demotion in the last year of life.
• Controlling for psychiatric morbidity (e.g., major depression), demographics, and protective factors (e.g., religiosity), job demotion was a leading predictor of death by suicide vs. natural causes.
• Those demoted at work in the last year of life were 7.29 times more apt to die of suicide than those who were not demoted.
• (Note a study of Hong Kong workers reported that 31% of suicides were in danger of demotion/job loss vs. only 8.3% controls (Law et al., 2014).

Clues to Locating Areas of High Suicide & High Work
Stress • Suicide by Occupational
Groups • Suicide By Industry
Distribution of Work Stress: Occupations
• Suicide Rates Vary by Occupation. This variation may provide a window into which jobs are more or less stressful than average.
• Can suggest where suicide prevention resources are most needed.
Occupations with High/Low Suicide Risk
Data from the National Mortality Detail file found 15/32 occupations (32 with an adequate number of suicides to calculate reliable rates) had elevated or less than average suicide risk ratios. However, controlling out demographic covariates (age, gender, race, marital status), only 8/32 had significantly elevated or lower suicide risk. Elevated risk: doctors, nurses, dentists, artists, social workers, mathematicians/scientists. Lower Risk: Adjusted odds ratios indicated that clerks and farm workers had significantly lower suicide risk. (Stack, S. 2001. Occupation & suicide. Social Science Quarterly, 82 (June), 384-396.
Suicide Risk by Industry
• Suicide rates vary by industry. • This variation can also provide a window into
locating which industries have the highest suicide risk.
• An analysis of the Nat’l Longitudinal Mortality Study (1979-1989) determined that of 12 industries the ones most at risk of high suicide included: – Mining 4.39 RR Construction 2.59 RR – Reference category: Financial services/insurance
Suicide Risk by Industry
Kposowa, A. (1999). Suicide mortality in the United States: Differentials by industrial and occupational group. American Journal of Industrial Medicine, 36, 645-652.
DISCUSSION: Problem: Lack of Data on Job Stress & Suicide in the USA
• Large American datasets and databases with data on suicides and a control group (e.g., natural deaths, living controls) tend to have few, if any, measures of work stress – Nat’l Mortality Followback Surveys, – Multiple Cause of Death Files, – Mental Health Research Network database. – Suggest: Need a new Mortality Followback Survey or
Expansion of another large survey (e.g., National Health Interview Survey) to include items on work stress (especially ERI).
Other Suggestions for Future Research
1. Following leads in work stress and mental illness/physical illness, more attention needs to be drawn to ERI, effort-rewards imbalance (fair rewards) as a predictor of suicide.
2. Evidence on job control/demands as well as social support is rather mixed. Organizational stress & loss (e.g., demotion) may prove to be better predictors of suicide than job control/demands & social support on the job.
3. Controls for mental illness. Half of the existing work does not control for a possible covariate of suicide/work strain: mental illness. Future work needs to build a strong research model with adjustments for this factor.
4. Family stress + work stress interactions (Feskanich, 2002). Work stress may have its full impact on suicide in combination with other stress. Feskanich, D. et al. 2002. Stress & suicide in the nurses’ health study. J. of Epid . & Com. Health,56,95-98.
Improvements to the CDC NVDRS
1. Analysis of the narratives in the National Violent Death Reporting System is needed to clarity the degree to which each category of job problems is connected to suicide deaths. For example, of 30,000 cases there are over 3,000 suicides that were linked to job problems. Unfortunately, CDC coders do not code the subtypes of job problems.
2. Possibly CDC could instruct their coders to start to break down “job problems” into subcategories so we would have national estimates of just what kinds of work stress are most likely to foster suicide deaths.
3. It would help tremendously to include a control group of natural deaths with which the suicides (& homicides) could be compared.

Primary prevention: The WHO guidelines (2006)
“Worker suicide is a complex interaction between individual vulnerabilities (such as mental health
problems), stressful working conditions, and living conditions (including social and environmental
stressors)…”
“The over-riding goal should be to create a working environment that is respectful to the individual, maintains worker integrity, and minimizes and
counteracts stress”
