“…Adjustment to the night shift is known to be much more difficult than to other shifts that do not require night duty (Folkard, 2008;Reinberg et al, 2007). In fact, few if any workers fully adjust to the night shift, because of direct disruption of the rest/activity pattern, desynchronization of the circadian system, and disruption of the 24 h pattern of socialization (Burch et al, 2005;Folkard, 2008;Giebel et al, 2008;Reinberg et al, 1984;Reinberg and Ashkenazi, 2008;Weibel et al, 1996;Wirtz et al, 2008). Although excessive sleepiness was most frequent among those involved in arrangements that mandated nighttime work (i.e., NW and DENS), we found it was frequent among all the New York state work groups.…”

Rotating shift and permanent night work arrangements are known to compromise sleep. This study examined the effects of work schedule on sleep duration, excessive sleepiness, sleep attacks, driving, and domestic/professional accidents. A representative sample of the general population of the state of New York--3,345 individuals > or = 18 yrs of age--was interviewed by telephone regarding their sleep and psychiatric and organic disorders. Multivariate models were applied to derive odds ratios (OR) after adjustment for age, sex, physical illness, mental disorders, obstructive sleep apnea, and sleep duration. On average (+/-SE), workers slept 6.7 +/- 1.5 h, but 40% slept < 6.5 h/main sleep episode. Short-sleep duration (< 6 h) was strongly associated with fixed night (OR: 1.7) and day-evening-night shiftwork arrangement (OR: 1.9). Some 20% of the workers manifested excessive sleepiness in situations requiring high attention, and it was associated with the fixed night (OR: 3.3) and day-evening-night work arrangements (OR: 1.5). Overall, 5% of the workers reported sleep attacks; however, they occurred three-times more frequently in the fixed night (15.3%) than other work arrangements (OR: 3.2). Driving accidents during the previous 12 months were reported by 3.6% of the workers and were associated with fixed night (OR: 3.9) and day-evening-night (OR: 2.1) work schedules. The findings of this study indicate that working outside the regular daytime hours was strongly associated with shorter sleep duration, sleepiness, and driving accident risk. Night work is the most disrupting, as it is associated with insufficient sleep during the designated rest span and excessive sleepiness and sleep attacks during the span of activity, with an associated consequence being increased driving accident risk.

Abnormal working hours can reduce work health, general wellbeing, and productivity, independent from a profession. To inform future approaches for automatic stress and overload detection, this paper establishes empirically collected measures of the work patterns of software engineers. To this aim, we perform the first largescale study of software engineers' working hours by investigating the time stamps of commit activities of 86 large open source software projects, both containing hired and volunteer developers. We find that two thirds of software engineers mainly follow typical office hours, empirically established to be from 10h to 18h, and do not usually work during nights and weekends. Large variations between projects and individuals exist. Surprisingly, we found no support that project maturation would decrease abnormal working hours. In the Firefox case study, we found that hired developers work more during office hours while seniority, either in terms of number of commits or job status, did not impact working hours. We conclude that the use of working hours or timestamps of work products for stress detection requires establishing baselines at the level of individuals.

“…This model could be used for evaluating and designing work schedules, comparable to existing guidelines for the design of shift work (e.g., Beermann, 1998). Based on the results presented herein, the spectrum analysis of work schedules and their interference with social or biological rhythms (Giebel et al, 2008) can be regarded as a promising approach to the investigation of A. Wirtz et al 260 the relationships between the dynamics and/or temporal distribution of working times and the social or biological well-being of employees.…”

Periodic components inherent in actual schedules of flexible working hours and their interference with social rhythms were measured using spectrum analysis. The resulting indicators of periodicity and interference were then related to the reported social impairments of workers. The results show that a suppression of the 24 and the 168 h (seven-day) components (absence of periodicity) in the work schedules predicts reported social impairment. However, even if there are relatively strong 24 and 168 h components left in the work schedules, their interference with the social rhythm (using the phase difference between working hours and the utility of time) further predicts impairment. The results thus indicate that the periodicity of working hours and the amount of (social) desynchronization induced by flexible work schedules can be used both for predicting the impairing effects of the specific work schedules on social well-being as well as for the design of socially acceptable flexible work hours.
