An organizational working time reduction and its impact on three domains of mental well-being of employees: a panel study.

BACKGROUND: Work hours are an important aspect of one's job and these in turn have the potential to impact people's well-being. Much research investigating the link between working hours and well-being uses cross-sectional data. Longitudinal studies, especially those studying the same subjects changing their working time, can study the impact of work time more clearly. Using panel data, this study aims to explore the impact of a reduction in working time on three domains of well-being: general well-being, job-related well-being (positive work experience) and work-family well-being (work-family conflict). In addition, our study offers insights into the role of concomitant changes in work and private circumstances of employees as we investigate whether the impact of shorter working hours for well-being is mediated by changes in the participants' and circumstances related to paid and unpaid work resources. METHOD: An organization of about 60 (female) employees trialed a shorter workweek for one calendar year in 2019. All full-time employees reduced their hours. The part-time working employees can be used as a control group. Panel data (survey and time-use diary data) of a 30-h workweek trial in Belgium was collected in four waves over two years in a pre- and post-intervention design. Change over time (waves) was analyzed through multilevel growth models. RESULT: A decrease in work-family conflict was observed during the shorter workweek. Part of this decrease is explained by concomitant changes in work and private circumstances, such as sufficiency in free time, schedule control, and satisfaction with work pressure. Positive work experience and general well-being tend to have decreased during the shorter workweek, although this could partly be explained by other organizational changes and not by the reduction in working hours per se. Schedule control helped suppress these somewhat negative effects of organizational changes on positive work experience. CONCLUSION: Reduced working hours have the largest and most positive impact on work-family conflict. The feeling of having enough leisure time contributes to this increased well-being. Especially for women, who were the majority in this study, a reduction in working time might be beneficial as they often bear more responsibility for household work and care tasks. Next to the duration of working time, schedule control/autonomy has an important impact on well-being.

Effects of the combined exposure to chemicals and unusual working hours.

OBJECTIVE: Both exposure to occupational chemicals and to unusual working hours have well documented effects on health. Determination of occupational exposure limits is, however, usually based on chemical-only exposure and assumes an 8-h workday, 5 days/week and a 40-h work week. A significant proportion of the workforce is exposed to chemicals while working in other work schedules. This review thus aimed to synthesize and evaluate the scientific support for a combined effect of unusual working hours and chemical exposure and, if possible, give recommendations for OEL adjustments to account for unusual working hours. METHODS: The search for articles was made as part of the preparation of a report for the Nordic Expert Group for Criteria Documentation of Health Risks from Chemicals. In this report, unusual working hours were categorized as shift work or extended (>8 h) working hours. Inclusion criteria were observational studies in the English language published up to November 2021 in peer-reviewed journals, with explicit metrics of exposure (chemicals and unusual working hours) and of health outcome, and which explicitly tested the association between exposure and outcome. Search engines of seven databases were used. RESULTS: Of the initially 15 400 identified papers, 9 studies published between 1985 and 2021 met the inclusion criteria, 7 of which showed significant associations. Results from a few of the studies, i.e. regarding effects of dust and endotoxin on lung function, effects of acetone on sleep quality and tiredness, effects of carbon disulphide on coronary artery disease and effects of chemicals on spontaneous abortion, suggested more pronounced effects during night shifts compared to during day shifts. DISCUSSION: The reviewed data is considered insufficient to conclude on recommendations for OEL adjustment for shift work. Suggested areas of future studies are mentioned. CONCLUSION: Further studies about the effects of the combined exposure to unusual working hours and chemical exposure are essential for risk assessment, and for recommendation of potential OEL adjustments. What is important about this paper? Effects of chemical agents at the workplace may depend not only on exposure level and duration but also on the time of exposure in relation to the circadian rhythm. This study reviewed the scientific support for a combined effect of unusual working hours and chemical exposure and revealed an obvious need for additional studies regarding the complex interplay of the two different exposures with respect to adverse health effects.

Association between long working hours and metabolic dysfunction-associated steatotic liver disease: a nationwide population-based study in Korea.

OBJECTIVES: Long working hour is a known risk factor for metabolic diseases. We explored the association between working hours and metabolic dysfunction-associated steatotic liver disease (MASLD). STUDY DESIGN: Data on working hours among 22,818 workers (11,999 females) from the Korea National Health and Nutrition Examination Survey (2013-2021) were used for this study. METHODS: MASLD was defined as a combination of hepatic steatosis combined with one or more of cardiometabolic risk factors (overweight/obesity, prediabetes/diabetes, raised blood pressure, hypertriglyceridemia, low high-density lipoprotein cholesterol). Hepatic steatosis was assessed using the hepatic steatosis index. Logistic regression was used to estimate the odds ratios (ORs) and 95% confidence intervals (CIs). RESULTS: The overall prevalence of MASLD was 30.4% in men and 18.1% in women. Among male workers, 20.2% worked ≥55 h/week, whereas among female workers, 10.1% worked ≥55 h/week. Compared with working 35-40 h/week, working ≥55 h/week was positively associated with overweight/obesity (OR: 1.21; 95% CI: 1.05-1.40), pre-diabetes mellitus (pre-DM)/DM (OR: 1.20; 95% CI: 1.04-1.38), raised blood pressure (OR: 1.17; 95% CI: 1.02-1.35), and presence of any cardiometabolic risk factors (OR: 1.56; 95% CI: 1.21-2.02). The adjusted OR (95% CI) of the association between working hours and MASLD was 1.27 (1.09-1.47) for ≥55 h/week compared with working 35-40 h/week in male workers. In female workers, long working hours were not clearly associated with cardiometabolic risk factors and MASLD. CONCLUSION: Long working hours are positively associated with MASLD among Korean male workers. Policy interventions are needed to mitigate the adverse metabolic effects of prolonged working hours.

Workload and short sickness absences in a cohort of Finnish hospital employees.

This article used register data on day-to-day working hours of hospital employees combined with patient characteristics at work unit (wards) level to measure workload and its implications for short, self-certified sickness absences. We measured statistically the average nursing treatment burden of different patient mixes in hospital wards, and then analyzed the overall workload (intensity) of working days by comparing it to the actual available nursing workforce. We found that a significant part of the workload variation occurred between working days, and it was related to unexpected changes in the number of employees. In atypical situations a long work shift was associated with caring for patients with fewer resources. The high workload of a day increased the risk of short sickness absences along the following 3-week period. The results show that managing short-term workload variability should be a key aim from the perspective of well-being at work, and that combining different data sources can provide novel, important insights to the measurement of workload.

Behind the times? Associations of working-time autonomy with health-related and occupational outcomes in health care personnel- a latent profile analysis.

BACKGROUND: In the light of personnel shortage, the health care sector is facing the challenge to combine increasing employees' as well as patients' needs. The aim of this study was to investigate the association between working-time autonomy and health-related (fatigue, psychosomatic complaints and work ability), as well as occupational outcomes (job satisfaction and turnover intention) in a large sample of health care employees. METHOD: Based on data of the BauA-Working Time survey, a sample of n = 1,093 employees working in the health care sector was analysed. Outcomes were assessed by the German Fatigue Scale, the Work Ability-Index and single-item measurements. Besides descriptive analyses, latent profile analysis (LPA) was used to determine clusters of employees based on working-time autonomy. Subsequently, regression analyses have been conducted to examine the association between autonomy clusters with health-related and occupational outcomes, controlling for sociodemographic characteristics and employment status. RESULTS: LPA revealed that a three-cluster model was most suitable: high autonomy (cluster 1), medium autonomy (cluster 2) and low autonomy (cluster 3). The extracted profiles of working-time autonomy differed significantly in terms of sociodemographic and occupational characteristics, but not in terms of average working hours per week or monthly household income. The multivariate regression analysis revealed that being in the low-autonomy cluster was associated with more psychosomatic health complaints (IRR: 1.427, p = 0.008), lower work ability (OR 0.339, p < 0.001), as well as less job satisfaction (OR 0.216, p < 0.001). DISCUSSION: Overall, the analyses indicate that it is crucial to prospectively consider working-time autonomy as an important factor of satisfaction, well-being and turnover intention in health care employees.

Association between long working hours and the development of suicidal ideation among female workers: An 8-year population-based study using the Korean Longitudinal Survey of Women & Family (2012-2020).

Long working hours and overwork have recently emerged as pressing public health concerns. We explored the association between long working hours and suicidal ideation in female workers. A total of 8017 women (24,331 observations) from the fourth to eighth waves of the Korean Longitudinal Survey of Women and Families (2012-2020) were analyzed. To address the repeated measurements within each participant, we employed a generalized estimating equation to estimate the odds ratio (OR) and 95% confidence intervals (CIs). The prevalence of suicidal ideation was 1.9% for those working 35-40 h/week and 4.4% for those working ≥55 h/week. Compared to individuals working 35-40 h/week, those working ≥55 h/week were more likely to experience concurrent suicidal ideation (OR [95% CI]:1.85 [1.43-2.39]). The OR (95% CI) of the association between long working hours and onset of suicidal ideation in the subsequent wave was 1.69 (1.20-2.38) for ≥55 h/week. In subgroup analysis, this association was pronounced among workers with low-income levels (OR [95% CI]: 1.97 [1.29-3.02]) and blue-collar occupations (OR [95% CI]: 2.27 [1.41-3.66]). Policy efforts are required to protect the mental health of female workers exposed to long working hours.

Stability of social jetlag and sleep timing into the second year of the Covid-19 pandemic: Results from a longitudinal study of a nationally representative adult sample in Ireland.

The early phase of the COVID-19 pandemic has previously been associated with marked changes in sleep/wake timing arising from the imposition of society-wide infection mitigation measures. Such observations are considered of broader significance as they reveal the social pressures that sleep timing normally operates under. In order to assess how persistent such changes were as the COVID-19 pandemic developed, we assessed sleep timing and quality in a longitudinal study of a nationally-representative sample of Irish adults with data collected at two time-points (December 2021 and March 2021). Data on social jetlag and chronotype was derived from the micro Munich Chronotype Questionnaire from 830 and 843 participants who provided data in December 2020 and March 2021 respectively, of which 338 contributed data to both timepoints. Demographics and measures of insomnia symptoms, anxiety, depression and loneliness were also collected, and data was analysed both within-subjects and cross-sectionally within data waves. Social jetlag (the mismatch between sleep timing on "work" and "free" days) and other measures of sleep timing were stable across the two time-points, although insomnia symptoms improved slightly from December 2020 to March 2021. The mean social jetlag at both timepoints was ~ 30 minutes, considerably lesser than reported pre-pandemic levels in similar populations. Multiple regression analysis of cross-sectional data reveals that the timing of midsleep on "free" days was only a weak-to-moderate predictor of social jetlag, whilst hours worked per week was the strongest predictor of social jetlag. Requirement for "face-to-face" contact with the public at work and urban location of residence also emerged as predictors of social jetlag, although insomnia, anxiety and depression symptoms and loneliness rating did not. We conclude that sleep timing changes that occurred during the initial phase of the COVID-19 pandemic persisted into the second year of the pandemic, and these results further illustrate the key roles working practices and other social factors have in shaping social jetlag.

Family structures and parents' occupational models: its impact on children's diabetes.

AIMS: This study examines how family-related factors influence the management of children and adolescents with type 1 diabetes (T1DM). We investigate the relationship between family patterns, parental work schedules and metabolic control. MATERIALS AND METHODS: We analysed data from a nationwide diabetes survey (DPV) focusing on HbA1c, severe hypoglycaemia, diabetic ketoacidosis, hospital admissions and inpatient treatment duration. We used linear regression and negative binomial regression models. Our study includes 15,340 children under the age of 18 with data on family structure and parental division of labour. RESULTS: Children from two-parent households have better HbA1c outcomes than children from single-parent, blended or no-parent households (p < .0001). Higher HbA1C levels are associated with children living with an unemployed father, as opposed to those with full-time working parents or with a full-time working father and a part-time working mother (p < .001). CONCLUSIONS: These findings emphasise the importance of carefully considering family structure and working time models in the management of paediatric T1DM. Our results highlight risk factors within the family environment and emphasise the need for family-focused counselling of high-risk patients or severe cases in clinical practice.

The relationship between working time mismatch and depression according to actual hours worked.

OBJECTIVES: The effect of the combination of working hours and working time mismatch on depression is unknown. This study was undertaken to confirm the relationship between working time mismatch and depression with respect to hours worked. MATERIAL AND METHODS: The data of 45 514 adult workers that participated in the 6th Korean Working Conditions Survey (KWCS-VI 2020) were reviewed. Depression was defined using the World Health Organization 5 Well-Being Index (WHO-5) cut-off score of 50. Working time mismatch was defined as a difference between actual and desired working hours. To identify associations between working hour mismatch and depression according to weekly hours worked, stratification analysis was conducted by dividing the study subjects into 3 groups based on actual hours worked weekly (<40 h, 40-<52 h, or ≥52 h). Multiple logistic regression analysis adjusted for potential confounders was performed to calculate odds ratios of depression. RESULTS: In the <40 h, 40-<52 h, and ≥52 h groups, the odds ratios (OR) of working more hours than desired were 1.51, 95% CI: 1.20-1.92 (<40 h), 1.70, 95% CI: 1.58-1.84 (40-<52 h), and 1.55, 95% CI: 1.41-1.69 (≥52 h), respectively, compared to a matched actual versus desired working hours group (the matched group). On the other hand, the odds ratios of working fewer hours than desired were 1.17, 95% CI: 1.07-1.27 (<40 h), 1.38, 95% CI: 1.20-1.60 (40-<52 h), and 1.98, 95% CI: 1.24-3.17 (≥52 h), respectively. The risk of depression was found to increase significantly with working time mismatch within all 3 working hour groups. CONCLUSIONS: Working time mismatch increases the risk of worker depression regardless of hours worked. Int J Occup Med Environ Health. 2023;36(6):788-97.

Effect of robot for medication management on home care professionals' use of working time in older people's home care: a non-randomized controlled clinical trial.

BACKGROUND: Medication management has a key role in the daily tasks of home care professionals delivered to older clients in home care. The aim of this study was to examine the effect of using a robot for medication management on home care professionals´ use of working time. METHODS: A pragmatic non-randomized controlled clinical trial was conducted. The participants were home care professionals who carried out home care clients' medication management. Home care clients were allocated into intervention groups (IG) and control groups (CG) (n = 64 and 46, respectively) based on whether or not they received the robot. Data were collected using the Working Time Tracking Form prior to and 1 and 2 months after introducing the intervention. The t-test was used to compare the groups at each three timepoints. Analysis of Covariance was used to examine the groups' differences for the total time for medications as the number of visits per day as the covariate. RESULTS: With robot use, the total amount of home visits decreased by 89.4% and 92.4% after 1 and 2 months of intervention use, respectively, compared to pre-intervention (p < 0.001). The total working time used for medication management considering the number of visits per day decreased from 54.2 min (95% CI 37.4-44.3) to 34.9 min (31.4-38.3), i.e., by slightly over 19 min (p < 0.001) in the IG group. During the follow-up, the total working time used for medication management considering the number of visits per day remained the same in the CG group. CONCLUSION: Using a robot for medication management had a notable effect on decreasing the use of working time of home care professionals. For health services, decreased use of working time for medication management means that the time saved can be assigned to services that cannot be replaced otherwise. More digital solutions should be developed based on home care clients' and professionals' needs to meet the challenge of the growing number of older people in need of home care and ensure their safety. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT05908604 retrospectively registered (18/06/2023).

Current perceptions and working time models of female urologists in Germany: results of a large-scale survey.

PURPOSE: Female urologists are distinctly underrepresented in leading positions. The reasons behind this inequity remain unclear, with some suggesting factors such as family responsibilities, part-time work and insufficient mentorship. This study aimed to explore and characterize the working conditions of female urologists in Germany, with a focus on factors influencing the working time model. METHODS: A questionnaire was developed and distributed to 1343 female members of the German Society of Urology between February and March 2022. The survey consisted of 43 questions covering the categories demographics, occupation situation, satisfaction at work, family situation, career aspects and research activity. RESULTS: Of the 487 female German urologists who participated in the survey, 167 (34.3%) worked part-time. Doctors in training were significantly less likely to work part-time than colleagues who had completed their specialist training (p < 0.001). Only 10% of female doctors in training reported working part-time. Similarly, having children (p < 0.001) and engaging in scientific activities (p = 0.03) were independent factors influencing part-time work, with children increasing the likelihood of working part-time as expected, while scientifically active female urologists were more likely to work full-time. CONCLUSION: This study provides the largest survey on the situation of female urologists in German-speaking countries to date. Part-time work during specialist training is rare, while more than 50% of female urologists with children work part-time. With the projected decline in the number of practicing physicians and the increasing demand for medical attention, it is crucial to find ways to retain and support healthcare professionals, particularly female urologists.

Development of algorithm for work intensity evaluation using excess overwork index of construction workers with real-time heart rate measurement device.

Background: The construction workers are vulnerable to fatigue due to high physical workload. This study aimed to investigate the relationship between overwork and heart rate in construction workers and propose a scheme to prevent overwork in advance. Methods: We measured the heart rates of construction workers at a construction site of a residential and commercial complex in Seoul from August to October 2021 and develop an index that monitors overwork in real-time. A total of 66 Korean workers participated in the study, wearing real-time heart rate monitoring equipment. The relative heart rate (RHR) was calculated using the minimum and maximum heart rates, and the maximum acceptable working time (MAWT) was estimated using RHR to calculate the workload. The overwork index (OI) was defined as the cumulative workload evaluated with the MAWT. An appropriate scenario line (PSL) was set as an index that can be compared to the OI to evaluate the degree of overwork in real-time. The excess overwork index (EOI) was evaluated in real-time during work performance using the difference between the OI and the PSL. The EOI value was used to perform receiver operating characteristic (ROC) curve analysis to find the optimal cut-off value for classification of overwork state. Results: Of the 60 participants analyzed, 28 (46.7%) were classified as the overwork group based on their RHR. ROC curve analysis showed that the EOI was a good predictor of overwork, with an area under the curve of 0.824. The optimal cut-off values ranged from 21.8% to 24.0% depending on the method used to determine the cut-off point. Conclusion: The EOI showed promising results as a predictive tool to assess overwork in real-time using heart rate monitoring and calculation through MAWT. Further research is needed to assess physical workload accurately and determine cut-off values across industries.

Resident physician duty hours, resting times and European Working Time Directive compliance in Spain: a cross-sectional study.

BACKGROUND: There is a growing interest in understanding the impact of duty hours and resting times on training outcomes and the well-being of resident physicians. However, to this date no state-wide analysis exists in any European country. OBJECTIVES: Our aim is to describe the shift work scheduling and to detail the degree of compliance with the Spanish legislation and the European Working Time Directive (EWTD) of Spanish resident physicians, focusing on territorial and specialty distribution. MATERIAL AND METHODS: A descriptive cross-sectional analytical study was designed through an online survey adapted from the existing literature. RESULTS: Out of the 2035 surveyed resident physicians undergoing PGT in Spain, 80.49% exceeded the 48 h per week limit set by the EWTD and 13% of them did not rest after a 24-h on-call shift. The mean number of on-call shifts in the last 3 months was 15.03, with the highest mean reported in Asturias, La Rioja, and Extremadura. 51.6% of respondents had a day-off after a Saturday on-call shift. Significant differences are observed by region and type of specialty. CONCLUSION: Resident physicians in Spain greatly exceed the established 48 h/week EWTD limit. Likewise, non-compliance with labor regulations regarding mandatory rest after on-call duty and minimum weekly rest periods are observed.

Working time variation and mental health during the Covid-19 pandemic in China.

The Covid-19 pandemic has brought about a significant shift in labor market dynamics, leading to a notable increase in labor market flexibilization. One prominent aspect of this transformation is the growing variation in working time patterns. The irregular and unpredictable nature of working time may contribute to increased stress levels, difficulty in establishing routines, and challenges in maintaining work-life boundaries. Drawing on China General Social survey 2021, this study aims to examine (1) the relationship between working time variation and mental health during the Covid-19 pandemic in China; (2) whether the relationship can be mediated by work-family conflict; (3) to what extent the relationship varies across occupations. We find that working time variation is associated with significantly worse mental health during the Covid-19 pandemic in China, and around half of the negative effect can be mediated by increased work-family conflict. Moreover, the negative association is more pronounced among non-professional occupations than professional occupations. Overall, these findings shed light on the detrimental impact of working time variation on mental health and its potential mechanism, highlighting how novel work paradigm may interact with existing labor market inequalities to shape workers' mental health.

[Factors influencing job satisfaction of female urologists-results of a survey by the German Society of Urology (DGU)]. / Einflussfaktoren für die Berufszufriedenheit von Urologinnen ­ Ergebnisse einer Befragung der Deutschen Gesellschaft für Urologie e. V. (DGU).

INTRODUCTION: Job satisfaction is a valuable good. However, literature on job satisfaction of female and male physicians, especially in the field of urology, is scarce. Therefore, the aim of this study was to evaluate job satisfaction among female members of the German Society of Urology (DGU). MATERIALS AND METHODS: An online questionnaire was sent to 1343 female members of the DGU in Germany, Austria, and Switzerland. The responses of 521 female physicians were statistically analyzed regarding baseline characteristics and in relation to job satisfaction and satisfaction with the choice of specialty. RESULTS: The median age of the participants was 37 (IQR 33; 45) years. While 91% of the respondents were rather or very satisfied with their choice of specialty-urology-only about 54% of the female urologists were satisfied with their job situation. Of the female urologists satisfied (vs. not satisfied) with their professional situation, 95% (vs. 87%) were also satisfied with their choice of urology as their specialty. Satisfaction with the working time model (odds ratio [OR] 9.61) and feeling unequal treatment (OR: 0.18) were independent predictors of satisfaction with the professional situation. CONCLUSION: Considering the increasing proportion of women in the health sector, it is important to identify factors influencing decisions on career and choice of specialty as well as career progression. Achieving career goals, increasing satisfaction with the working time model, and reducing unequal treatment or discrimination are central arguments for sustainably increasing the job satisfaction of female urologists.

What do Portuguese cardiologists think and feel about their work?

INTRODUCTION AND OBJECTIVES: This study reports the results of an online survey carried out by the Portuguese Society of Cardiology about its medical members' work characteristics before and during the COVID-19 pandemic, their job satisfaction, work motivation, and burnout. METHODS: A sample of 157 participants answered a questionnaire with demographic, professional, and health-related information, followed by questionnaires on job satisfaction and motivation designed and validated for this study and a Portuguese version of the Maslach Burnout Inventory. Data were analyzed through descriptive statistics, ANOVA, and MANOVA, considering gender, professional level, and sector of activity, respectively. Multiple regression was used to assess the impact of job satisfaction and motivation on burnout. RESULTS: The only variable that distinguished participants was sector of activity. Cardiologists working in the private sector worked fewer weekly hours during COVID-19, while those in the public sector worked more. The latter expressed more desire to reduce their working hours than those who worked in private medicine and in both sectors. There were no differences between sectors in work motivation, while job satisfaction was higher in the private sector. Moreover, job satisfaction negatively predicted burnout. CONCLUSIONS: Our findings point to a deterioration in working conditions during the COVID-19 pandemic, with its consequences being felt especially in the public sector, which may have contributed to the lower levels of satisfaction among cardiologists who worked exclusively in this sector, but also for those working in both public and private sectors.

Working time arrangements and exhaustion: The role of recovery experiences and satisfaction with the schedule.

Working time arrangements may be a source of strain and entail negative consequences for workers, one of which can be exhaustion. Based on the job demands-resources and the conservation of resources theories, this study explores recovery experiences from work and satisfaction with the work schedule as possible resources that may prevent or minimize such negative consequences. With a sample of 386 workers (n = 287 women; 99 men) and using a cluster analysis, we identified five working time arrangements: fixed standardized, part-time, irregular standardized, flexible standardized, and nonstandard work schedule (NWS). A one-way ANOVA found that workers in the irregular standardized schedule report higher exhaustion compared to the fixed standardized and the part-time. Exhaustion of workers in NWS is higher compared to the part-time workers. A multiple linear regression analysis found that the link between recovery experiences and exhaustion varies according to the working time arrangement. Lastly, an interaction analysis confirmed the moderator effect of satisfaction with the work schedule in the relationship between recovery experiences and exhaustion for the whole sample. When this analysis was performed separately for each cluster, this effect was only significant for NWS and by disentangling this finding by recovery dimensions, only relaxation had a significant interaction effect. This study clarifies the links between different recovery experiences and exhaustion, and points to the importance of satisfaction with the work schedule in facilitating recovery under demanding working time arrangements. Results are discussed considering the complex nature of the work-family interface.

Distribution of working hour characteristics by race, age, gender, and shift schedule among U.S. manufacturing workers.

Shift work is a common occupational exposure, however, few studies have examined aspects of shift work beyond night work and long hours, such as rotational patterns or weekend work, which may contribute to poor health through disruption of the body's circadian rhythms. In this manuscript, we calculated the prevalence of working hour characteristics using algorithms for type (e.g., day), duration, intensity, rotational direction, and social aspects (e.g., weekend work) in a nationwide cohort of American manufacturing workers (N = 23,044) between 2003 and 2014. Distributions of working hour characteristics were examined by schedules (e.g., permanent day, day/night) and demographics, and were cross-classified in a matrix to examine co-occurrence. Approximately 55% of shifts may cause circadian rhythm disruption as they were non-day shifts or day shifts with a quick return or rotation, or were 13 h or longer. Older workers, female workers, and White workers worked permanent day shifts most often, while workers of color worked more day/night schedules. Night and evening shifts had more frequent shift rotations, quick returns, and longer hours than day shifts. Yet, day shifts, which are presumed to have little negative circadian impact, may cause circadian rhythm disruption as long hours, quick returns and rotations also occurred within day shifts.

What do hematologists and oncologists consider necessary for their career? Results of an online survey in Germany, Austria and Switzerland.

PURPOSE: This study aimed to find out more about factors that hinder physicians' careers, especially with regard to gender differences, and which future working conditions they would prefer. METHODS: In an online survey, members of the professional societies of Hematology and Oncology in Germany, Austria and Switzerland were asked to rate factors that might hinder or facilitate their professional career. Data analysis included χ2-tests, t tests and analyses of variance. RESULTS: 469 physicians participated (61% female, response rate 9.1%). 40% of the participants experience a lack of compatibility between family life and career. Female physicians with children living in their household especially feel restricted in their professional development. The most preferred conditions for improving compatibility were flexible working hours (72%), opportunities to work in home office (71%), better opportunities for specialist training (51%) and enabling managerial activities on a part-time basis (73%). Both female and male physicians would like fathers to be encouraged to take parental leave to the same extent as mothers (50%). They would, e.g., like to see more flexible drop-off and pickup times for children (71%) and more childcare options offered by their employer (61%). CONCLUSION: Results suggest various options for promoting compatibility of family life and work, e.g., by family-friendly working time models and part-time offers breaking with traditional role models. Managerial positions might be offered on a regular part-time basis. Structured qualification programs could enable the compatibility of clinical work, research and family life. Childcare services should preferably be provided in line with existing needs.

El cuidado como cuestión de tiempo: una perspectiva feminista sobre el tiempo cotidiano de cuidadoras de personas adultas con discapacidad / Caregiving as a matter of time: A feminist perspective of the daily time of women caregivers of adults with disabilities / O cuidado como questão de tempo: uma perspectiva feminista sobre o tempo cotidiano de mulheres cuidadoras de pessoas adultas com deficiência

El artículo aborda el carácter histórico y político del tiempo, por considerarle un articulador de la existencia humana, a partir de una lectura crítica de la vida cotidiana. La reproducción de la temporalidad está mediada por el trabajo, el que, analizado desde una perspectiva feminista-marxista, permite reconocer desigualdades en la experiencia del tiempo de hombres y mujeres, basadas en la división sexual del trabajo. Para profundizar en este fenómeno se presentan resultados derivados de una investigación cualitativa que buscó analizar la experiencia del tiempo cotidiano de mujeres que realizan el trabajo de cuidados de personas adultas con discapacidad en Santiago de Chile. Se realizaron entrevistas semiestructuradas y observaciones participantes en los contextos cotidianos de ocho mujeres, reconociendo que su experiencia del tiempo depende de otras personas, que está densificada por la continua realización simultánea de trabajos no remunerados y que no distingue tiempos libres, de ocio ni por fuera del cuidado. Se concluye reconociendo que las desigualdades de género también producen desigualdades en la experiencia del tiempo, lo que insta a avanzar en políticas sociales que reconozcan el cuidado como un derecho social para que las mujeres puedan construir experiencias de sentido, azar, demora y libertad.

The article addresses time's historical and political character, considering it an articulator of human existence from a critical reading of everyday life. The reproduction of temporality is mediated by work, which, analyzed from a feminist-Marxist perspective, allows the recognition of inequalities in the experience of time for men and women based on the sexual division of labor. To delve into this phenomenon, the article presents the results from qualitative research that sought to analyze the daily experience of women who are caregivers of adults with disabilities in Santiago de Chile. Methodologically, semi-structured interviews and participant observations were made in the everyday contexts of eight women, recognizing that their experience of time depends on other people, that it is densified by the continuous and simultaneous performance of unpaid work, and that it does not distinguish free time, leisure, or time outside care. It concludes by recognizing that gender inequalities also produce inequalities in the experience of time, which urges progress in social policies recognizing care as a social right so that women can build experiences of meaning, chance, delay, and freedom.

O artigo aborda a natureza histórica e política do tempo, considerando-o um articulador da existência humana, a partir de uma leitura crítica da vida cotidiana. A reprodução da temporalidade é mediada pelo trabalho, que, analisado a partir de uma perspectiva feminista-marxista, permite reconhecer desigualdades na experiência do tempo de homens e mulheres, a partir da divisão sexual do trabalho. Para aprofundar este fenômeno, são apresentados os resultados derivados de uma pesquisa qualitativa, que buscou analisar a experiência do tempo cotidiano de mulheres que realizam o trabalho de cuidar de adultos com deficiência em Santiago do Chile. Foram realizadas entrevistas semiestruturadas e observações participantes nos contextos cotidianos de oito mulheres, reconhecendo que sua experiência do tempo depende de outras pessoas, que está intensificada pelo desempenho contínuo e simultâneo de trabalhos não remunerados, e que não distingue os tempos livres, de lazer nem externo ao cuidado. Conclui-se reconhecendo que as desigualdades de gênero também produzem desigualdades na experiência do tempo, o que urge avançar em políticas sociais que reconheçam o cuidado como um direito social, para que as mulheres possam construir experiências de sentido, casualidade, lentidão e liberdade.
