Commuting, overtime and cardiac autonomic activity in Tokyo
The relation between short-term heart rate variability (HRV) and commuting time or overtime was investigated in 223 Japanese white-collar workers. Chronic stress or fatigue resulting from long commuting time or extensive overtime appeared to cause a sympathodominant state in these individuals. Although these shifts in HRV are not direct indicators of disease, they may induce cardiovascular abnormalities related to the onset of heart disease.

Absenteeism in organizations: Motivational approaches to identify determinants and suggestions for health promotion in the workplace
Fehlzeiten in Organisationen: Motivationspsychologische Ansätze zur Ursachenanalyse und Vorschläge für die Gesundheitsförderung am Arbeitsplatz [in German]
From a review of recent research findings on the causes of absenteeism it is concluded that not enough attention has been paid to the connection between absenteeism and conditions in the workplace. When employees are not motivated enough by their work they may stay away from work for a day or two every now and then and blame it on minor health problems. In order to cut this kind of avoidable absenteeism it is recommended to make work more appealing to employees. In addition, employees should be informed about the consequences of absenteeism to the organization.

Effect of overtime work on 24-hour ambulatory blood pressure
Blood pressure measurements over a 24h period were compared among several groups of male white-collar workers: overtime groups (average 60 hours or more overtime per month) and control groups (average 30 hours or less overtime per month). For those with normal blood pressure and those with mild hypertension, the 24h average blood pressure of the overtime groups was higher than that of the control groups. For a group who periodically did overtime work, the 24h average blood pressure and the heart rate during the busy period increased. The burden on the cardiovascular system of white-collar workers increases with overtime work.

Maximum performance time and heart rate: A theoretical approach
Durée limite de travail et fréquence cardiaque - Approche théorique [in French]
Maximum performance time decreases with work intensity. This relationship characterizes endurance and it varies from person to person. The knowledge of this individual endurance relationship allows: from the occupational health point of view, to predict the intensity of effort not to be exceeded for a specific duration; from the performance point of view, to predict the optimal intensity of effort according to its duration. Heart rate is used to estimate the relative work load. An exponential endurance time/relative intensity relationship is hypothesized and the logarithmic rather than arithmetic mean of instantaneous heart rate is therefore recommended to estimate average work intensity. The individual exhaustion relationship is calculated from this heart rate logarithmic mean. This method takes into better consideration peak values for intense activities, particularly in lactic anaerobia.

Effects of various work time schedules on cooks
Auswirkungen unterschiedlicher Arbeitszeitmodelle bei Köchen [in German]
The effects of 3 work time schedules on the social life and health of 45 male and 6 female cooks in the hotel industry in Germany were studied with the help of questionnaires. Of the participants 22 worked during the day between 6 am and 5 pm, 12 alternated between 2 shifts from 6 am to 2 pm and 2 pm to 10 pm, 17 worked from the morning to the early afternoon and in the evening with a 2 to 3 h break in between. The latter 2 groups were significantly more negative than the first group about the usefulness of their spare time to make and maintain social contacts. There was no difference between the 3 groups with regard to psychosomatic disorders.

Social tolerance of working time scheduling in nursing
In a study of 297 German nurses, tolerance of different working time schedules (WTS) was analyzed for six factors: job security and access to the labour market; income; health; family relationships; participation in social life; degree of autonomy for WTS. Results show: dominance of health-related and social aspects in the social tolerance of working time scheduling; large differences in stress, burnout and well-being for nurses on different WTSs linked to day-time, shiftwork and permanent night work; strong covariate effects of autonomy on working time scheduling as well as strong covariate effects of sex on the influence that different WTSs exert on stress, burnout and well-being.

A study on the full application of the Labour Standards Law in forestry
Rōdō kijun hō no ringyō eno kanzen tekiyō ni kansuru ichi kōsatsu [in Japanese]
Because forestry is an outdoor activity, the Japanese Labour Standards Law, as it applies to forestry, must be revised to take care of its special features. This paper examines the proposed modifications. Particular attention must be made to the introduction of labour-saving machinery, necessitated by the need of the industry to stay competitive. A coherent national approach is needed to take into account the changing nature of forestry work and the need to preserve the environment.

Night and shift work conditions and health in the Japanese chemical and allied industries: Results of a questionnaire study
Kagaku kōgyō kanren rōdōsha no shin'ya kōtai kimmujōken to kenkō: shitsumonshi chōsahō ni yoru kentō [in Japanese]
Survey of members of a union representing about 7% of the regular workers in the sector. Data were obtained from the union, and from 4045 male workers, including 1844 shift workers, and 873 women, including 16 shift workers. Because of the small sample of female shift workers, the study focused on the male group. There were 79 rotating shift systems and 4 regular night duty systems. Although shift workers complained more frequently than day workers of cumulative fatigue and expressed more anxiety about their health, there was no difference between the groups in health status. Shift workers complained more often of problems with work schedules and of shortcomings in the work environment. The proportion of smokers was higher among the shift workers. Both shift and day workers averaged 6.7h/day of sleep at home, but the former reported poor environments for daytime sleeping after a night shift. Those who could nap for more than 2h during a night shift reported less fatigue than other shift workers. Workers in the 5-team, 3-shift system promoted by the Japanese union movement did not necessarily enjoy better health or better working conditions. Where such systems were adopted without increasing the number of shift workers, increases were reported in work intensity, working hours, double shifts and duty calls on days off.

Three-year follow-up study of health conditions among dental technicians
Shika gikoshi no kenko jotai ni kansuru sannen kan ni watarutsuseki chosa [in Japanese]
To provide detailed data on the health and working conditions of dental technicians in Japan, 39 male members of a professional association responded to questionnaires and underwent medical examinations in 1991 and 1994. The mean working time per day fell from 13.3h to 12.1h. Good health habits (longer sleep, more exercise, less smoking) became more prevalent, but satisfaction decreased. Numbness in the arms and fingers was positively correlated with daily working hours but not with length of career. However, vibrotactile threshold did increase with length of career. The prevalences of cough and sputum were 10% and 20%, respectively. Small opacities were seen in chest x-rays in 20% of the cases; their number increased with length of career. This suggests that dust exposure is responsible for the respiratory symptoms. Further improvements in the working conditions of dental technicians are necessary.

CIS 95-770 Sleep and hours of work - Survey conducted in the framework of an industrial physician's work plan
Sommeil et horaires de travail - Enquête réalisée dans le cadre du plan d'activité du médecin du travail [in French]
Study conducted by 16 industrial physicians on the prevalence of sleep disturbances among the 25,000 workers of the national commodity/food market at Rungis, France. Occupations vary greatly from wholesale trade, transport, restaurants, self service food stores, retail stores, warehouse work to construction, tertiary sector (banking, insurance, computer work, etc.). Work patterns also vary greatly, as do hours of work (day-work, night-work, shift work (2 X 8, 3 X 8) as well as irregular shifts). The prevalence of sleep disturbances is high whether it relates to sleep quantity or quality, and is related to other disorders such as overweight, stress, high blood pressure, alcoholism, pathopsychologic disturbances and disruptions in family and social life.

Changes in the conditions of work by innovative ways of inter-company work distribution (Parts supply industry)
Veränderung der Arbeitsbedingungen durch neuartige Formen der zwischenbetrieblichen Arbeitsteilung (Zulieferindustrie) [in German]
The effects of new cost-saving measures by car manufacturers on work organization, conditions of work and personnel qualifications in the parts supply industry are described. Logistics, quality assurance, development and production of new products were studied. The role of computer-aided design and computer-aided manufacturing was taken into consideration. Conditions in Germany were compared with those in Japan. Information was obtained from the literature and from case studies of 2 car manufacturers and 87 suppliers in Germany. It was found that suppliers are increasingly under pressure concerning their inability to come to terms with new technologies, their use of outdated machinery, their inability to deliver in time, the high rate of faulty products delivered and the low qualification of their personnel.

Fire fighters' physical and mental fatigue in 24-hour shift work
24-Jikan kakujitsu kinmusha no hirō tokusei - shōbō taiin o taishō to shite [in Japanese]
Heart rate, blood pressure at rest, handgrip force, vertical jumping, body flexibility, physical working capacity, perceived exertion during bicycle exercise and subjective symptoms of 14 firefighters (aged 29-48) were measured for 10 consecutive days during which the subjects alternated between 24h on duty and 24hr off. The only statistically significant change over this period was a slight decrease in the height to which subjects could jump. Perceived exertion increased over the observation period for subjects in their 40s and decreased for the younger ones. Subjective symptoms of physical, mental and sensory fatigue increased over the 10 days, i.e., the 24hr off-duty period was insufficient for recovery. The 24hr shift, which involves mainly sedentary work at night, seems to produce psychological discomfort but to have little physical effect.

Effects of a change in shift work on health
Aspects of health were studied in a sample of factory workers who changed their pattern of working from "fortnight about" to three advancing shifts. Within the same factory and doing similar work there was a comparison group who were working permanent days only. The change in shifts was associated with more difficulty with sleep, more indigestion, higher alcohol consumption, reduced alertness and a worse social life. There was more minor psychiatric disturbance in those who worked three shifts than in those who worked days only.

Relationship of ergonomic stressors to birthweight and gestational age
Women in many occupations are exposed to ergonomic stressors (eg, prolonged standing, physical exertion, and long work weeks). After a consideration of the major methodological problems encountered in studying effects of ergonomic stressors on birthweight and gestational age, epidemiologic studies that have addressed this issue are reviewed. No individual ergonomic stressor has been consistently associated with effects on gestational age. However, most studies which have attempted to look at the cumulative effect of several stressors report that women in the highest exposure category are at higher risk of giving birth prematurely. In contrast, data regarding an association with birthweight are more variable, and firm conclusions cannot be drawn. While future studies that assess exposure to ergonomic stressors with a more comprehensive and quantitative approach are needed, current evidence is sufficient to suggest that clinicians should take ergonomic stressors into account in the assessment of their patients' risk for preterm delivery.

Preventing short-term strain through time-management coping
Report on a project investigating the effectiveness of time-management coping in the prevention of strain due to role overload. Structural regressions, a form of causal-correlational analysis, were used on repeated-measures questionnaire data from 96 working adults attending evening degree classes in business administration. Results showed that time-management techniques significantly lowered anxiety, but not depression or somatic symptoms. In addition, the effect of coping on axiety remained significant when social desirability was controlled. Anxiety did not influence subsequent coping, and no significant moderator effects were found.

Organisation of shorter working hours based on human needs
Menschengerechte Umsetzung von Arbeitszeitverkürzungen [in German]
In a food-processing plant, consultations took place in order to reorganise work time schedules according to the needs of the workers subsequent to a reduction of the work-week to 38h. In the plant, 278 men and 252 women alternated between two shifts, 71 men between three shifts and four men worked the night shift. In discussions with these employees the 2-10p.m. shift proved to be the most problematic one. Considerations of the social aspects and the health effects of various work-time schedules led to a proposal to cut this shift by 30min. Night shifts were also rearranged. Detailed summaries in German, English and French.

Working conditions and health among night workers in the Japanese service industry
Sābisu sangyō ni okeru shinya rōdō no rōdō eisei [in Japanese]
This questionnaire survey was conducted to clarify the relationships between night work conditions and psychosomatic complaints in the service industry. The subjects were full-time workers (N=307) and part-time workers (N=300) who were working in 3 service industries in which business hours were prolonged after 10 p.m. or covered a full 24 hours: convenience stores, family restaurants and fastfood restaurants, business hotels. 37.8% of full-time workers, and 81.7% of part-time workers expressed satisfaction with night work. The major reasons were "higher salaries", "more free time for themselves" and "suitability to their life styles". However, the job scope and responsibility of night work were much heavier than those of day work. 32.9%-43.4% of subjects excluding hotel clerks experienced night-work in addition to scheduled working days during the month preceding the study. As for psychosomatic symptoms, 64% of the subjects complained that they felt "a tendency to become fatigued", and it was the most frequent complaint. Factors related to night work which increased psychosomatic complaints were "working in family restaurants or fastfood restaurants", "doing same jobs at night as during the day", "night work in addition to scheduled working days", "less opportunity to take rests or naps during night work", and "difficulty to be granted their requests to decide working schedules".

Performance, alertness, and sleep after 3-5 years of 12h shift: A follow-up study
Control room operators at a continuous processing plant have been working a 12h/3-4 day rotating shift schedule for over 3 years. After 7 months on this schedule, initial assessment indicated decrements in performance and alertness, and a mild to moderate sleep debt, when the 12h shift schedule was compared to the previously-worked 8h shift schedule. In an effort to track long-term adaptation to the schedule, a 3-5 year follow-up evaluation using the same set of measures was conducted. Long-term follow-up testing revealed persistent decrements in performance and alertness attributable to 12h shifts, and 1-3h reduction in total sleep time after 12h night shifts. Little deterioration in performance or alertness was observed across the workweek, which suggested day-to-day recovery from the extended workshift. The popularity of the 12h shift schedule at this worksite indicates that the workers are willing to tolerate extra fatigue to derive other benefits from this schedule.

La durée du travail dans les postes et télécommunications - Rapport III [in French]
Working paper and report prepared by the ILO for its Joint Committee for Postal and Telecommunications Services (Geneva, 1991). Chapter 1 of this report outlines the specific context of working time in the postal and telecommunications services, focusing on the special needs of this sector, the implications of recent innovations and the characteristics of its labour force. Chapter 2 examines the regulation of several important aspects of working time such as normal hours of work, overtime, rest periods, annual leave, public holidays, maternity leave, and it highlights differences in regulations between postal and telecommunications services. Chapter 3 deals with the organisation of working time. It examines night and shift work, part-time work and temporary and casual work. Special attention is paid to innovative experiences such as flexible working time, modular working time systems, job sharing, compressed work-weeks and telework. The report ends with a summary of the main points made in each chapter and a list of suggested points for discussion.

Working hours and commuting time from the point of view of occupational health management - A study on the influence on lifestyle
Shokuiki no kenkō kanri kara mita rōdō jikan to tsūkin jikan - raifusutairu e no eikyō ni tsuite no kōsatsu [in Japanese]
A survey was conducted among non-outdoor company workers on the influence of working and commuting time on lifestyle. Lifestyle was assessed in terms of daily habit items - smoking, drinking, exercise, sleeping hours, obesity, breakfast-taking, nutritional balance - and social life items - motivation to work, stress, social support, relaxation at home. Only 4.3% of workers worked more than 11 hours daily, while the majority worked 8 hours. When working time exceeded 10 hours, both daily habits and social life tended to become unsatisfactory. The commuting time, which was relatively short in general due to the adoption of flexible working hours, had no significant effects on lifestyle. Even in a community where working and commuting time was not excessively long, working hours had a significant effect on lifestyle, which should be considered in the health management of workers.

The strain of commuting to work
Belastungsdimensionen arbeitsbedingten Pendelns [in German]
Census data of 1988 are used to show that in the Federal Republic of Germany about 10.5 million employees commute more than 50km and/or more than 60min to work. This represents an increase of 90% within the last ten years. The stress and strain aspects are discussed in the light of an empirical regional study. Of 308 commuters using the train from Fulda to Frankfurt 63% rated the perceived strain unbearable or heavy. Details are given on: profession; reasons for commuting; physical, mental, social, temporal and economic implications of commuting.

Schichtarbeit, nach arbeitswissenschaftlichen Kriterien geplant, reduziert die Belastungen für die Beschäftigten [in German]
Work-rest schedules for shift work including night work are presented. They take into consideration work weeks as short as 36 hours and recommendations by studies of numerous shift workers, to reduce sleep disturbance, fatigue, impairment of social life and of circadian rhythm. A new system of scheduling irregular shift work is outlined. It is presently being tested by employees of a television station in Germany.

The problem of adjusting threshold limit values (TLVs) for non-conventional work schedules: utility of physiologically-based pharmacokinetic modeling
Le problème de l'ajustement des valeurs limites d'exposition (VLE) pour des horaires de travail non-conventionnels: utilité de la modélisation pharmacocinétique à base physiologique [in French]
In this study, a physiologically based pharmacokinetic (PB-PK) model was used to simulate exposure to selected solvents for variable lengths of time, with the use of a computer programme and data from published literature. Results are reported for a 12-hour and an 8-hour workshift. For all the solvents studied, the percentage of correction of TLVs fell within a fairly narrow range of 57-65%. Although the method of PB-PK modelling is generally to be preferred to that of calculation by simple proportions, results of the study suggested that, in case of urgent needs, the corrected TLVs obtained from simple proportional adjustment (67%) can be satisfactory, at least for the solvents examined in this study.

The application of 8-hour occupational exposure limits to non-standard work schedules offshore
This paper reviews general methods for adjustment of 8-h occupational exposure limits to offshore work schedules and recommends toxicokinetic models for calculating adjustment factors. These factors may be used to develop exposure limits whose aim is to provide the same degree of worker protection offshore as the original limits. A general formula for regular, repetitive work is used to calculate adjustment factors as functions of biological half-lives for 2 different offshore work schedules. In both, the work period is 12h a day for 14 consecutive days but the off-duty period between tours of duty is either 2 or 3 weeks. The worst case adjustment factor is 0.60, occurring at biological half-lives of 78 and 76h, respectively. At lower biological half-lives, the adjustment factors are identical for the 2 work schedules, whereas at higher biological half-lives they differ.

Part-time work in international perspective
Le travail à temps partiel dans le monde [in French]
Part-time work is condemned by many as a threat to full-time jobs, a precarious form of employment and a source of unequal treatment of women workers. It is also widely defended as a regular, well-protected way to reconcile the needs and preferences of workers with the operational requirements of enterprises, to create jobs, and to benefit workers with family responsibilities, workers approaching retirement and other special groups. There are now more than 50 million part-time workers in the industrialised market economics alone, and in some countries nearly half of all working women are part-timers. This article examines the reasons of part-time work; the level of legislative protection; national programmes which increase access to part-time employment; and the differing forms of part-time work in practice.

Long workdays versus restdays: assessing fatigue and alertness with a portable performance battery
A test battery for assessing psychological and behavioural fatigue was used to compare restdays to a workweek of five 12-h days at a simulated data-entry job. The observed increase in data entry errors across the workday and the workweek, as well as subjective reports of increased tiredness on workdays, indicated that the work regimen was fatiguing. Test battery performance results paralleled those observations. On workdays, grammatical reasoning was faster but less accurate than on rest days; digit addition was slower; simple, dual and choice reaction times were slower; hand steadiness decreased.
