Evaluation of the impact of shiftwork and chronotype on the workers of the imprint and cutting/welding sectors of a flexible packaging manufacturer

This article presents a study on the impact of shiftwork and chronotype on the perception of the work conditions, workload and adjustment to shiftwork by the workers of two sectors of a flexible packaging manufacturer, which operates in three fixed shifts. The workers are allocated in one of the shifts (morning, evening and night shifts) without evaluation of their chronotype and/or social needs. The workers' evaluation of the shift system and their work show that they prefer a fixed shift and to work in a shift compatible with their chronotype. The workers with chonotype uncompatible with the shift time tend to be less satisfied with the work conditions and content and feel more discomfort/pain.     

Analysis of the workload imposed on the workers of the imprint and cutting/welding sectors of a flexible packaging manufacturer

This article presents a study on the evaluation of the workload imposed to workers of two sectors of a flexible packaging manufacturer that operates in three shifts. The workers are allocated in one of the shifts (morning, evening and night shifts) without evaluation of their chronotype and/or social needs. The Imprint sector has a more dynamic work, which is done only by man due to the effort demanded by handling loads. The work in the Cutting/Welding sector is static, done mainly by women. The results showed that the overall workload was the same in the Imprint and Cutting/Welding sectors, because physical effort for load handling is higher in the former but the latter involves high static load. The levels of urinary catecholamines and salivary cortisol were consistent with the workers biological clock showing that none of the workers changed his/her biological cycle to accommodate to the time of the shift schedule.     

Shift work--problems and its impact on female nurses in Udaipur, Rajasthan India

Abstract : There is good evidence that shift work has negative effects on workers health, safety and performance. It is quite appropriate that attention is paid to this very important feature of socio-technical systems, which may adversely affect mental and physical health, social life and safety of shift workers. Research into the impact of shift work on professionals has consistently identified a range of negative outcomes in physical, psychological, and social domains (Akerstedt, 1988; Costa, Lievore, Casaletti, Gaffuri, & Folkard, 1989; Kogi, 2005; Paley & Tepas, 1994). Hospitals, the biggest employer in the health care field, employ more night shift workers than any other industry. It can therefore be inferred that in medical domain high percentage of workforce may be affected by problems related to shift work. Thus the present study will provide knowledge base for the problems faced by the female nurses. The present study was undertaken with an objective of getting an insight into the problems faced by female nurses in shift work. . It was found that the female nurses in India worked on roaster pattern of change in shift every seven days. They did not have a say in the change of duties, it could only be done on mutual grounds. Partners of younger group did not much adjust to their shift pattern this created stress among the nurses.The results showed that the female nurses in both the age groups i.e. 30-45 years and 45-60 years faced many problems related to health and well being, fatigue, social and domestic situations. They could not give much time to their children in particular. Travelling in nights was risky for them. Common problem was the insufficient sleep during night shifts. The nurses had to cater to the needs of the family, children in particular along with the adjustments to be made due to shift work. They had to sometimes do the night duties and attend social functions as a part of their duty. Children and husband in some cases did not cooperate this lead to frustration. When asked as to whether they would could shift job if they get regular one more than 50 % said yes this means that there need to be come training and intervention for the shift workers and their family so that the problems faced and their impact on personal health of the female nurses could be reduced.     

Preparing,Working, Recovering: Gendered Experiences of Night Work among Women and their Families

The negative physiological consequences of night work are well evidenced, but there has been limited research on the gendered consequences of night work for partnered women with children. This paper examines women's experiences of night work by drawing on qualitative interview and audio sleep diary data with 20 UK female nurses working non‐regular rotating shifts, together with interview and diary data from their male partners and children. The analysis shows how the lived experience of women's night work is characterized by three phases, which we discuss within a timescape perspective. Alongside changes to paid work and sleep during the period of night shifts, the ‘preparation’ and ‘recovery’ phases of women's night work involve intense periods of considerable additional unpaid and unrecognized work and anxiety. Gendered expectations for household management and family wellbeing mean that women night workers undertake considerable responsibility for complex planning before night shifts begin, and re‐enter established domestic routines within hours after night shifts end. Women maintain continuity for their families by actively managing the impacts of night work. This enables the fulfilment and ‘display’ of successful and normative gendered patterns of domestic responsibility, which appears to be central to women's own coping with night shifts.     

Minor psychiatric disorders among nursing workers--is there an association with current or former night work?

We aimed at analyzing whether Minor Psychiatric Disorders (MPD) is associated to night work either currently or in the past. A cross-sectional study was conducted at three public hospitals in Brazil, with female nursing workers. Data collection (N=1,134) was based on a comprehensive questionnaire that included the self-reported questionnaire (SRQ-20) for screening of MPD. Former night workers were subdivided into three groups according to their reasons for leaving night work: (i) directly related to work, (ii) related to better reconcile with studies or another job, and (iii) related to health, sleep, fatigue or stress. Binomial logistic regression was performed, with adjustment for potential confounders. A dose response gradient was observed between current night work and MPD (OR=1.5; 95% CI: 1.1-2.2 and OR=2.1; 95%CI: 1.5-3.1 for those who worked up to five nights and six or more nights per 2-week span, respectively). Potential detrimental effects of night work were confirmed. The association between working at night and MPD was not restricted to current night workers as workers who left night work for health/fatigue/sleep/strain also showed higher chances of reporting MPD (OR=1.8;95%CI:1.14-2.90). Results contribute to the scientific debate on the impact of night work on health and wellbeing.     

Effects of extended work shifts on employee fatigue, health, satisfaction, work/family balance, and patient safety

12-hour shifts are quickly spreading in Europe. From our multivariate analysis concerning 25,924 European nurses, including twenty explanatory variables simultaneously, we found that work schedule itself is not a major determinant factor. Nurses aim to choose or accept night shifts or 12-hour shift in order to reduce their work/home conflicts, however, at the expense of the patient's safety, as well as their own health and safety. Therefore, it is important to develop measures, such as extended child care, association of nurses to the elaboration of their rota, 9- or 10-hour shifts in the afternoon, allowing naps during night shifts, and reduction of changing shifts with short notice. Work schedules must be organized in order to allow time for shift handover, social support and team building.     

Parental Work Schedules and Children's Cognitive Trajectories

Previous work has shown an association between mothers' nonstandard work schedules and children's well-being. We built on this research by examining the relationship between parental shift work and children's reading and math trajectories from age 5/6 to 13/14. Using data (N=7,105) from the National Longitudinal Survey of Youth and growth curve modeling, we found that children's math and reading trajectories were related to parents' type of nonstandard shifts (i.e., evening, night, or variable). We found that having a mother who worked more years at a night shift was associated with lower reading scores, having a mother work more years at evening or night shifts was associated with reduced math trajectories, and having a father work more years at an evening shift was associated with reduced math scores. Mediation tests suggest that eating meals together, parental knowledge about children's whereabouts, and certain after-school activities might help explain these results.     

Gender, Nonstandard Work Schedules, and Marital Quality

Relatively few studies have focused on the effects of working late and rotating shifts on marital dynamics. This study addressed the limitations of prior studies by sampling from a sector of the economy (i.e., grocery and drug store workers) where shift work and rotating schedules were common, and by controlling for numerous accompanying disruptive effects of shift work on marital quality. Results show that working late shifts reduces marital quality among men, whereas among women, job-family spillover explained away marital quality effects of working rotating schedules. These results suggest that more than men, women remain largely responsible for family life irrespective of work schedules, yet further research on how family lives are affected by work schedules is needed.     

The Impact of Higher Fixed Pay and Lower Bonuses on Productivity

This study analyzes the effects of performance related pay on productivity exploiting a change in the payment structure of a large Dutch marketing company. Specifically, we investigate the consequences for company sales of higher fixed pay in combination with lower bonuses. Exploiting shift level data of individual workers we find that average productivity decreases when the pay structure shifts more to fixed pay. Further analysis shows that this drop in productivity is larger for older workers and for high-ability employees, while over time the negative effect of the new system becomes smaller.     

“I want to be there when he graduates:” Foster parents show higher levels of commitment than group care providers

Group care is a frequent placement for adolescents placed in out of home care when their birth parents' care is deemed unsafe. In the present study, we assessed whether foster parents show greater commitment to children than group care providers. Given that group care represents a number of living arrangements, we considered both shift care (where staff work shifts and do not live with the children) and cottage care (where staff live for extended periods of time with the children in a group living context). Commitment was assessed using the This Is My Child Interview (adapted for adolescents). Thirty-one foster parents, 18 shift workers, and 28 cottage care providers were interviewed. As predicted, foster parents showed higher levels of commitment than both shift care workers and cottage care providers, and the associations held when children's externalizing behaviors and the number of children the caregivers had cared for were controlled. The results suggest that foster care promotes greater commitment among caregivers than other out of home placements, and add to other findings that favor foster care as the out of home placement of choice for adolescents.     

Daily rhythm of salivary IL-1ß, cortisol and melatonin in day and night workers

Shiftwork-induced sleep deprivation and circadian disruption probably leads to an increase in the production of cytokines and dysregulation of innate immune system, respectively. This project aims evaluating changes in salivary IL-1 beta, cortisol, and melatonin in night workers. Method. Two day and three night healthy workers participated in this study. Sleep was evaluated by actimetry and activity protocols. Saliva was collected at waking and bedtime the last workday and the following two days-off and was analyzed by ELISA. Results. Neither sleep duration nor efficiency showed any association with salivary IL-1beta. IL-1beta levels were higher at waking than at bedtime during working days for all workers, but only one day and one night-worker maintained this pattern and hormone rhythms during days off. For this night worker, melatonin levels were shifted to daytime. A second one presented clear alterations in IL-1beta and hormone rhythms on days-off. Conclusions. Our preliminary results suggest that night work can disturb the variation pattern of salivary IL-1beta. No association of this variation with sleep was observed. It seems that disruption in hormone rhythms interfere with salivary IL-1beta production. IL- 1beta production pattern seems to be maintained when rhythms are present, in spite of a shift in melatonin secretion.     

Women's working conditions in hospital cleaning: a case study

Hospital cleaning work, as health care work, is mainly performed by women all over Europe. Hospital cleaning activities represent a poorly studied sector although very important also for patient's health. We applied the Method of Organizational Congruencies to study cleaning work in three typical hospital units (Emergency Room, Haematology, General Medicine) of a roman University hospital where 198 women cleaners work. We analyzed the 731 technical actions performed in the three shifts and the related Organizational Constraints (OC). Working outsourcing, no occupational risks training, washing personal equipment at home, standing, long walking, early morning and night shift in emergency room, high monotony (>10 actions per hour) contact with biological and chemicals materials, risk conditions of accidents, artificial lights, hot microclimate and working in a cure setting represent the main Organizational Constraints. Differences among the three Units are discussed together with the importance of considering cleaning hospital as a preventive action towards hospital clinical risk.     

Raising awareness of psychosocial factors in the occurrence of low back symptoms in developing countries

Although there is strong evidence that single physical, psychosocial and organisational risk factors are each independent predictors of low back symptoms (LBS), little is known about their combination/interaction, particularly in those working in developing countries. A total of 1294 Indonesian coal mining industry workers reported information about physical, psychosocial, and organisational factors using self-reported questionnaires and were placed into one of four combination exposure groups: 1) high physical (working with bent trunk; whole body vibration exposure; lifting) and high psychosocial (high effort; low reward; work stress), 2) high physical and low psychosocial, 3) low physical and high psychosocial, and 4) low physical and low psychosocial (as the reference group). The odds of LBS in the high physical and high psychosocial group was 5.15 times (95% confidence interval 2.69-9.86) that of the reference group. Psychosocial factors played a more important role than physical factors in increasing the likelihood of reporting LBS. Permanent and night shift workers were more likely to report LBS. These findings imply that efforts to reduce LBS in this workplace should address both psychosocial and physical factors but psychosocial factors should be the priority, with a special focus on permanent and night shift workers.     

Increased of Brazilian productivity in the slaughterhouse sector: a review

Due to Brazil is a tropical country has activities in occupational exposure to cold restricted to few sectors especially the meatpacking industry. Taking into account that the country in 2010, was again the largest exporter of poultry meat in the world and consequently employing a large number of workers for their slaughter and processing. The search for greater productivity can result in an increase in work rate, as indicated in this sector as monotonous, repetitive and uncomfortable. According the Programa de Frigorífico it was found that within six years, about 20% of the six thousand workers in a slaughterhouse in southern Brazil, received welfare benefits due to musculoskeletal diseases. Adding to this, the lack of parameters for the Brazilian standardization concerning occupational activities carried out in cold. Although several epidemiological studies point to the cold as a risk factor for occurrence or aggravation of musculoskeletal disorders, research in this field is still limited and often contradictory conclusions. This article aims to review developments concerning the poultry industry and the fridge in Brazil, as well as raising the question about the increased productivity of the slaughterhouse, since it has already shown a high prevalence of musculoskeletal disorders related to work.     

Effectiveness of problem solving skills in case management on return to work for workers with injuries

The present study aims to explore the case management model by using problem solving skills in assisting workers with injuries in returning to work. A total of five workers with injuries were enrolled and there were four stages during the whole case management process including a medical rehabilitation stage (stage I), a compensation stage (stage II), a return to work stage (stage III) and a follow-up stage (stage IV) respectively. Case managers provided services by using problem solving skills to tackle the problems which workers with injuries may encounter during all four stages. Outcome measurement showed one case return to the same company same job, two returns to different companies and different jobs, the others have self employed work. This study suggested that case management using the problem solving skills of occupational rehabilitation was beneficial to workers with injuries on return to work.     

Parental Work Schedules and Child Overweight or Obesity: Does Family Structure Matter?

The authors used longitudinal data from the Fragile Families and Child Wellbeing Study (N = 5,482) to investigate whether maternal and paternal work schedules affect child overweight or obesity. They took the novel step of examining whether this effect is consistent for children living in different family structures. Findings from child fixed effects models suggest that the probability of child overweight or obesity was higher for children living with mothers who worked standard shifts at a primary job and nonstandard shifts at a secondary job compared to children living with mothers who worked a standard shift at a primary job only. Fathers' work schedules were not associated with child overweight or obesity. Unexpectedly, maternal standard shift work at a primary job and nonstandard shift work at a secondary job was associated with overweight or obesity only among children living with married biological parents.     

Retraining programmes in social work: career considerations,factors influencing the decision to study social work and professional preferences among students

The current study sought to examine the differences between retraining programme (RP) students in social work (SW) and mainstream programme (MP) students regarding career considerations, factors influencing the decision to study SW and professional preferences. RPs are similar to fast-track training programmes known in the UK, as they offer graduates from other disciplines a qualification in SW. This study was conducted among 125 SW students in Israel: 56 in the RP, where studying SW was their secondary choice (after graduating in a different academic discipline) and 69 MP students for whom SW was their first choice for a profession. Both groups were examined in their final year of studies. When choosing their profession, RP students attributed greater importance to considerations such as personal development, satisfaction and interest in treating people, while for MP students, working conditions were more important. In addition, RP students also preferred to engage in individual therapy and policy practice. Furthermore, there were several differences between the groups’ preferences regarding types of populations, services and sectors. Correlations were found between various preferences of populations, services and fieldwork training. Lastly, a higher percentage of RP students compared to MP students had expressed their intention to work as social workers once they complete their studies.     

Nonstandard Work and Marital Instability: Evidence From the National Longitudinal Survey of Youth

This article replicated and extended Harriet Presser's (2000) investigation of the linkages between nonstandard work and marital instability. We reexplored this question using data from a sample of 2,893 newlywed couples from the National Longitudinal Survey of Youth (NLSY) and using different analytic techniques. In contrast to Presser, we found that the key dimension of husbands' and wives' employment was nonemployment. Similar to Presser, we found that wives' working of fixed night shifts increased the risk of divorce, driven by the experience in marriages over 5 years in duration. However, we did not replicate Presser's finding that the effect is significant only among households with children; rather, wives' fixed night shifts were associated with divorce only among those without children.     

Shift Work,Role Overload,and the Transition to Parenthood

This article examines how the work hours, work schedules, and role overload of working‐class couples are related to depressive symptoms and relationship conflict across the transition to parenthood. Data are from 132 dual‐earner couples interviewed 5 times across the transition. Multilevel modeling analyses revealed that working evening or night shifts, as opposed to day shifts, was related to higher levels of depressive symptoms. For mothers only, working rotating shifts predicted relationship conflict. Increases in role overload were positively related to both depression and conflict; working a nonday shift explained variance in depression and conflict above and beyond role overload. Results suggest that for new parents, working nonday shifts may be a risk factor for depressive symptoms and relationship conflict.     

Shift work,father engagement,and the cognitive development of young children

The present study investigates whether the effect of fathers’ positive engagement on young children’s cognitive development is accentuated when one or both dual-earner parents is employed during nonstandard hours. Longitudinal regression models are fitted to three waves of nationally representative data from the Early Child Longitudinal Study-Birth Cohort. Father engagement when children are nine months old has an especially positive effect on children’s cognitive ability at age two when the father works during the day and the mother has a fixed evening or night shift. There are no interactions between shift work and engagement at age two in the whole sample, but subgroup analyses show that engagement has an especially strong effect on children who have a non-parent caregiver if both parents are shift workers. The results highlight the important role fathers play in couples with a shift worker, and provide a rationale for efforts to encourage and support their involvement.
