This study investigated the relationship between weekly working hours and the occurrence of cerebro-cardiovascular diseases using a case-crossover study design.
We investigated average working hours during the 7 days before the onset of illness (hazard period) and average weekly working hours between 8 days and 3 months before the onset of cerebro-cardiovascular diseases (control period) for 1,042 cases from the workers’ compensation database for 2009.
Among all subjects, the odds ratio by conditional logistic regression for the risk of cerebro-cardiovascular diseases with a 10 hr increase in average weekly working hours was 1.45 (95% confidence interval [CI]: 1.22–1.72), a significant association.
An increase in average weekly working hours may trigger the onset of cerebro-cardiovascular disease.

From the abstract:
Studies suggest that people who work long hours are at increased risk of stroke, but the association of long working hours with atrial fibrillation, the most common cardiac arrhythmia and a risk factor for stroke, is unknown. We examined the risk of atrial fibrillation in individuals working long hours (≥55 per week) and those working standard 35–40 h/week.
Methods and results:
In this prospective multi-cohort study from the Individual-Participant-Data Meta-analysis in Working Populations (IPD-Work) Consortium, the study population was 85 494 working men and women (mean age 43.4 years) with no recorded atrial fibrillation. Working hours were assessed at study baseline (1991–2004). Mean follow-up for incident atrial fibrillation was 10 years and cases were defined using data on electrocardiograms, hospital records, drug reimbursement registers, and death certificates. We identified 1061 new cases of atrial fibrillation (10-year cumulative incidence 12.4 per 1000). After adjustment for age, sex and socioeconomic status, individuals working long hours had a 1.4-fold increased risk of atrial fibrillation compared with those working standard hours (hazard ratio = 1.42, 95% CI = 1.13–1.80, P = 0.003). There was no significant heterogeneity between the cohort-specific effect estimates (I2 = 0%, P = 0.66) and the finding remained after excluding participants with coronary heart disease or stroke at baseline or during the follow-up (N = 2006, hazard ratio = 1.36, 95% CI = 1.05–1.76, P = 0.0180). Adjustment for potential confounding factors, such as obesity, risky alcohol use and high blood pressure, had little impact on this association.
Individuals who worked long hours were more likely to develop atrial fibrillation than those working standard hours.

From the abstract:
Data are used from the 1984–2016 Displaced Workers Surveys (DWS) to investigate the incidence and consequences of job loss, 1981–2015. These data show a record high rate of job loss in the Great Recession, with serious employment consequences for job losers, including very low rates of re-employment and difficulty finding full-time employment. The average reduction in weekly earnings for job losers making a full-time–full-time transition are relatively small, with a substantial minority reporting earning more on their new job than on the lost job. Most of the cost of job loss comes from difficulty finding new full-time employment.

Henry Ford’s ideal schedule for employees may no longer be relevant in today’s knowledge economy.

From the summary:
What this report finds: An ongoing structural shift toward more intensive use of part-time employment by many employers is driving the elevated rate of involuntary part-time work. Over six years into an economic recovery, the share of people working part time because they can only get part-time hours remains at recessionary levels. The number working part time involuntarily remains 44.6 percent higher than it was in 2007. This growth is being driven mainly by a few industries.
Why it matters: 6.4 million workers want full-time jobs but are working only part-time hours. Involuntary part-time workers are not only earning less income than they would prefer, but suffer because part-time jobs offer relatively lower wage rates and benefit coverage, and have more variable and unpredictable work schedules.
How we can fix the problem: In addition to traditional expansionary policies that would heighten demand for more hours of labor, here are seven policies that would help curb the excessive use of part-time employment and address the harmful effects of involuntary part-time working.

A good day’s sleep for night-shift workers is essential to health, safety and productivity.

From the summary:
Previous research by the AAA Foundation for Traffic Safety has estimated as many as 7% of all crashes, 13% of crashes that result in hospital admission, and 21% of fatal crashes involve driver drowsiness. However, the relationship between specific measures of sleep deprivation and crash risk has not been quantified in the general driving population. The results of this study indicate that drivers who usually sleep for less than 5 hours daily, drivers who have slept for less than 7 hours in the past 24 hours, and drivers who have slept for 1 or more hours less than their usual amount of sleep in the past 24 hours have significantly elevated crash rates. The estimated rate ratio for crash involvement associated with driving after only 4-5 hours of sleep compared with 7 hours or more is similar to the U.S. government’s estimates of the risk associated with driving with a blood alcohol concentration equal to or slightly above the legal limit for alcohol in the U.S.

In 2008, the State of Utah implemented a 4-day workweek for their employees. This article examines the impact on employees using a postimplementation survey. For employees on the 4-day schedule, there were no significant differences by gender on work–family balance or on the impact of the schedule. However, women did demonstrate slightly more positive attitudes toward the 4-day schedule. Employees with children at home reported lower work–family balance and greater impact of the 4-day schedule. In contrast, no difference in attitudes toward the 4-day schedule was found by age, although work–family balance differed among age groups. There were differences in work–family balance between employees on the 4-day schedule and those on traditional schedules; however, the more substantial factor was whether an employee selected his or her schedule. The current study highlights the importance of engaging employees when making significant organizational changes, such as transitioning from traditional work schedules to alternative schedules.

….Night shifts are a health hazard in either case, but for different reasons.
Would it be better not to keep throwing your body back and forth from diurnal to nocturnal? Cleveland Clinic, for one, tells patients both to “avoid frequently rotating shifts,” and also to “decrease the number of night shifts worked in a row.”
What? That’s scary if you have to work nights. Newly discovered health risks of working night shifts keep coming out: higher risks of coronary artery disease, diabetes, weight gain, and some cancers. The International Agency for Research on Cancer has listed night shifts as “probably carcinogenic.” Among people who’ve worked a decade of shift work, their brains show cognitive decline years in advance.
But these findings are almost always in people who do shift work—bouncing back and forth between nights and days. There’s even something called Shift Work Sleep Disorder (or Shift Work Disorder), defined by increased accidents, work-related errors, irritability, or mood problems…..

From the abstract:
The American labor market is increasingly unequal, characterized by extraordinary returns to work at the top of the market but rising precarity and instability at the bottom of the market. In addition to low wages, short tenure, few benefits, and nonstandard hours, many jobs in the retail and food service industries are characterized by a great deal of instability and unpredictability in work schedules. Such workplace practices may have detrimental effects on workers. However, the lack of existing suitable data has precluded empirical investigation of how such scheduling practices affect the health and wellbeing of workers and their families. We describe an innovative approach to survey data collection from targeted samples of service sector workers that allows us to collect previously unavailable data on scheduling practices and on health and wellbeing. We then use these data to show that exposure to unstable and unpredictable schedules is negatively associated with household financial security, worker health, and parenting practices.
