Associations between overtime and psychological health in high and low reward jobs

This study focused on the relationship between overtime and psychological health in high and low reward jobs, and in jobs with high and low external pressure to work overtime. Data were collected for 535 full-time employees of the Dutch Postal Service. In general, overtime was associated with negative work-home interference and negative home-work interference. Split-sample logistic regression analyses showed that employees reporting low rewards had elevated risks of burnout, negative work-home interference and slow recovery. In addition, the combination of overtime and low rewards was associated with negative home-work interference. A second analysis was conducted separately for employees who reported overtime in order to study the effects of external pressure to work overtime. In this subgroup, low rewards were associated with elevated risks of health complaints, emotional exhaustion and negative home-work interference. Moreover, employees who reported overtime and a high pressure to work overtime in combination with low rewards had elevated risks of poor recovery, cynicism, and negative work-home interference. The results suggest that even a limited number of hours of involuntary overtime is associated with adverse mental health, but only in low reward situations.     

Sleep disturbances in shift-workers: A marker for maladaptation syndrome

Abstract

This study aims to examine whether the relationship between overtime and well-being is influenced by the voluntary vs. involuntary (i.e., compulsory) nature of overtime work and by the presence or absence of rewards for overtime. We also explored the prevalence of these types of overtime and how they were related to work and personal characteristics. A survey was conducted among a representative sample of Dutch full-time employees (N=1612). AN(C)OVA was used to compare rewarded and unrewarded, voluntary and involuntary overtime workers on personal and work characteristics, fatigue, and work satisfaction. Most overtime workers were rewarded (62%). About half of the sample (n=814) could be classified as either voluntary or involuntary overtime workers, or as having “mixed reasons” to work overtime. Voluntary and unrewarded overtime workers had a relatively high income and favourable job characteristics. Involuntary overtime work was associated with relatively high fatigue and low satisfaction, especially for involuntary overtime workers without rewards who can be considered a burnout risk group. Voluntary overtime workers were non-fatigued and satisfied, even without rewards. It can be concluded that control over overtime and rewards for overtime are important for well-being. Moderate overtime work may not be a problem if it is done voluntarily. Moreover, the negative effects of compulsory overtime work may be partly offset by fair compensation for the extra work.     

Reciprocal relationships between psychosocial work characteristics and sleep problems: A two-wave study

Sleep problems are common and impair the health and productivity of employees. Work characteristics constitute one possible cause of sleep problems, and sleeping poorly might influence wellbeing and performance at work. This study examines the reciprocal associations between sleep problems and psychosocial work characteristics. The participants were 1744 full-time employed individuals (56% women; mean age 38 years in 2007) from the Young Finns study who responded to questionnaires on work characteristics (conceptualised by the demand–control model and effort–reward imbalance model) and sleep problems (Jenkins Sleep Scale) in 2007 and 2012. Cross-lagged structural equation models are used to examine the associations. The results show that low control and low rewards at baseline predicted sleep problems. Baseline sleep problems predicted higher effort, higher effort–reward imbalance, and lower reward. Sleep problems also predicted lower odds for belonging to the low (rather than high) job strain group and active jobs group. The association between work characteristics and sleep problems appears to be reciprocal, with a stressful work environment increasing sleep problems, and sleep problems influencing future work characteristics. The results emphasise the importance of interventions aimed at both enhancing sleep quality and reducing psychosocial risks at work.     

Effort-reward imbalance and work-home interference: a two-wave study among European male nurses

ABSTRACT

This one-year follow-up study among 1,421 male nurses from seven European countries tested the validity of the Effort-Reward Imbalance (ERI) model in predicting prospective vital exhaustion and work-home interference. We hypothesised that effort and lack of reward would have both main and interactive effects on future outcomes. Results of structural equation modelling (SEM) showed that effort was positively related to exhaustion and work-home interference, both simultaneously and over time. Lack of reward predicted increased exhaustion at follow-up, but effort-reward imbalance did not influence the outcomes. Additionally, Time 1 exhaustion predicted increased work-home interference and exhaustion at follow-up. These results do not support the ERI model, which postulates a primacy of effort-reward imbalance over main effects. Instead, the findings are in line with dual path models of job stress and work-home interference. Multi-group SEM showed partial cross-cultural metric invariance for the ERI measure of effort, but the ERI measure of rewards showed no metric measurement invariance, indicating its meaning is qualitatively different across cultures. Nevertheless, the main conclusions were markedly similar for each national sub-sample. We discuss the theoretical and practical implications of our study.     

Dimensions of work-home culture and their relations with the use of work-home arrangements and work-home interaction

This study examined the associations of work-home culture with (a) demographic and organizational characteristics, (b) the use of work-home arrangements, and (c) negative and positive work-home interaction, among 1,179 employees from one public and two private organizations. Substantial support was found for a 2-factor structure of a work-home culture measure differentiating between “support” (employees' perceptions of organization's, supervisors', and colleagues' responsiveness to work-family issues and to the use of work-home arrangements) and “hindrance” (employees' perceptions of career consequences and time demands that may prevent them from using work-home arrangements). This 2-factor structure appeared to be invariant across organizations, gender, and parental status. Significant relationships with organizational characteristics, the use of work-home arrangements, and work-home interaction supported the validity of these two cultural dimensions. It is concluded that if employers want to minimize work-home interference, to optimize positive work-home interaction, and to boost the use of work-home arrangements, they should create a work-home culture that is characterized by high support and low hindrance.     

The association between blood pressure and work stress: The importance of measuring isolated systolic hypertension

The objective was to study whether the relationships between elevated blood pressure and (a) work stress as related to the stressor overtime, and (b) unwinding after work, depend on what kind of criteria are used for the diagnosis of hypertension. A total of 126 healthy men (aged 20-66 years) employed in white-collar jobs were tested over 24 hours by means of ambulatory blood pressure monitoring on a regular working day. Four groups were defined according to their blood pressure status: normotensives (NT), hypertensives (HT), isolated systolic hypertensives (ISH), and isolated diastolic hypertensives (IDH). No differences of age, body mass index, overtime work, and disturbed unwinding were found between the normotensives and the hypertensives. ISH was found to be related to working overtime and to disturbed unwinding but not to biological risk factors; IDH, however, was related exclusively to the biological risk factor high body mass index. Thus, significant differences associated with overtime were found between ISH and both NT and IDH, with the isolated systolic hypertensives carrying out more than twice as much overtime as the normotensives or isolated diastolic hypertensives. More men with a disturbed ability to relax and vital exhaustion were found in the ISH group than in the NT group. It seems that, in addition to the usual diagnosis of hypertension, the classification of ISH and IDH adds new information about the relationship between blood pressure elevation and both work stress and disturbed unwinding.     

Work-home interaction from a work psychological perspective: Development and validation of a new questionnaire, the SWING

This paper reports on the stepwise development of a new questionnaire for measuring work-home interaction, i.e. the Survey Work-home Interaction—NijmeGen, the SWING). Inspired by insights from work psychology, more specifically from Effort-Recovery Theory (Meijman & Mulder, 1998), we defined work-home interaction by differentiating between the direction and quality of influence. Four types of work-home interaction were distinguished and measured by using 22 (including 13 self-developed) items. By using data from five independent samples (total N=2472), validity evidence was provided based on the internal structure of the questionnaire. The results showed that the questionnaire reliably measured four empirically distinct types of work-home interaction, and that this four-dimensional structure was largely invariant across the five samples as well as across relevant subgroups. Validity evidence was also provided based on the relations with external (theoretically relevant) variables (i.e. job characteristics, home characteristics, and indicators of health and well-being). The results generally supported the hypothesized relationships of these external variables with negative work-home interaction. Less support was found, however, for the hypothesized relationships with positive work-home interaction. This contributes to current literature as it employs a relatively broad conceptualization of work-home interaction and offers a promising tool that measures its multiple components across a wide variety of workers.     

Muscle pain and coping with working life in Norway: A review

ABSTRACT

Talking about work during leisure time is an important part of employees’ daily life and represents a behavioural pathway connecting work and home. However, past research has not paid much attention to this phenomenon of sharing work experiences during after-work hours, its possible antecedents and consequences. In the present study, we examine how interpersonal work experiences (i.e. social conflicts and perceived prosocial impact) are associated with work-related conversations during after-work hours, and how work-related conversations, in turn, are associated with affect at bedtime and in the next morning. A daily diary study with three measurement occasions per day over five consecutive workdays (N?=?144 employees) showed that negative work-related conversations during after-work hours were directly related to negative affect at bedtime and indirectly related to negative affect in the next morning. Positive work-related conversations were directly related to positive affect in the next morning. Moreover, perceived prosocial impact and positive work-related conversations during after work hours were negatively related to negative affect at bedtime. Our results suggest that employees actively shape their work-home boundaries by talking about work during after-work hours which show both beneficial and harmful associations with subsequent affective states.     

Rewarding creativity: when does it really matter?

This study examined the possibility that the relation between extrinsic rewards (e.g., pay and recognition) and employee creativity varied as a function of two conditions: employee job complexity and employee cognitive style. Our results showed a positive relation between extrinsic rewards and creativity for employees with an adaptive cognitive style who worked on relatively simple jobs. We found a weak relation between rewards and creativity for employees with an innovative cognitive style who worked on complex jobs and a negative relation for those in the adaptive style/complex job and innovative style/simple job conditions. We discussed theoretical and practical implications of these findings.     

An Examination of Reward Probability and Delivery Delays on Employee Performance

ABSTRACT

The effects of delay to delivery of earned monetary rewards were evaluated in program support employees. During study 1, an immediate reward delivery condition was implemented. During study 2, employees were exposed to increasing delays to reward delivery (i.e., 1, 2, 4, 8, 16, and 32 days). Employees continued to respond at high levels up to a 32-day delay. Study 3 held the 32-day delay constant but also evaluated three different probabilities of receiving the rewards: 1.0, .5, and .1. Employees continued to respond during delays but decreased responding when the probability of receiving the rewards decreased.     

Job Satisfaction,Work Environment,and Rewards: Motivational Theory Revisited

A model of job satisfaction integrating economic and work environment variables was developed and used for testing interactions between rewards and work environment hazards. Data came from a representative panel of Danish employees. Results showed that psychosocial work environment factors, like information about decisions concerning the work place, social support, and influence, have significant impacts on the level of job satisfaction. Maximizing rewards did not compensate public employees to an extent that ameliorated the negative effects on job satisfaction of experiencing low levels of any of these factors whereas influence did not impact job satisfaction of private employees.     

Work-home interference: How does it manifest itself from day to day?

Although work-home interference (WHI) refers to a process of negative interaction between the work and home domains, little attention has been paid to the actual processes involved in the within-person, day-to-day management of work and home. Therefore, this study investigated if, and how, a global report for the individual, of WHI (i.e., a general indicator of experienced WHI) is reflected in daily reports of WHI, in employees' daily activity patterns in the work and home domain, and in their daily health and well-being. Effort-Recovery theory (Meijman & Mulder, 1998) provided the theoretical basis for this study. Data were collected among 120 academic staff members (62% male) who completed a general questionnaire, addressing global WHI as well as demographical information, and who also participated in a 5-day daily diary study. WHI was measured using the 8-item WHI subscale of the Survey Work-home Interaction Nijmegen (SWING), with an adapted version being used for the diary studies. Results showed that global WHI: (1) was positively related to daily WHI; (2) was positively related to the time spent daily on overtime work in the evening; (3) was negatively related to the time spent daily on low-effort activities; and (4) was positively related to daily fatigue and sleep complaints. We conclude that Effort-Recovery theory seems promising for the study of WHI, and that diary studies are valuable, as these provide detailed insight into what global reports of WHI actually signify from day to day.     

When Engagement Meets Politics: Analysis of a Brazilian Public Institution

Perception of organizational politics (POP) is usually associated with counterproductive factors. The reason for this stigma is that generally when employees perceive self-interest actions or backstage manoeuvres, they identify obstacles to their careers. On the other hand, the concept work engagement represents physical, cognitive and emotional factors from its dimensions (vigor, dedication and absorption) that can connect employees to their jobs. This study aimed to investigate the relationship between the dimensions of work engagement and perceptions of organizational politics in a public institution. Data were collected from 847 employees of a public educational institution, followed by a hierarchical cluster analysis to characterize groups with high and low work engagement scores. Multiple linear regressions were performed for each cluster. It was found that in the low engagement group, the three constructs’ dimensions were negatively related to POP. In the high engagement group there was no negative relationship between those two concepts, but a positive association between dedication and perception of politics was found. The results show evidence that highly engaged civil servants do not identify politics as an obstacle to their career development. The study also suggests that POP level is high in public educational institutions.     

Trajectories of effort-reward imbalance in Swedish workers: Differences in demographic and work-related factors and associations with health

ABSTRACT

The aim of the study was to identify trajectories of effort-reward imbalance (ERI), to examine these with respect to demographic (age, gender, socio-economic position) and work-related (employment contract, work hours, shift work, sector) factors, and to investigate associations with different health indicators (self-rated health, depressive symptoms, migraine, sickness absence). The study used four waves of data (N?=?6702), collected biennially within the Swedish Longitudinal Occupational Survey of Health (SLOSH). Using latent class growth modelling, we identified four trajectories: a stable low imbalance trajectory, which comprised 90% of all participants, and three change trajectories including a decreasing trajectory (4% of the participants), an inverted U-shaped trajectory and an increasing imbalance trajectory, both in 3% of the participants. Results indicate that a sizeable proportion of Swedish employees’ experience imbalance between efforts and rewards at work. The most favourable trajectory comprised relatively more men and was characterised by better work-related characteristics than the less favourable ERI trajectories. All change trajectories were dominated by women and employees in the public sector. Health developments followed ERI trajectories, such that less favourable trajectories associated with impaired health and more favourable trajectories associated with better health. Sickness absence increased among all ERI trajectories, most so for the decreasing and increasing ERI trajectory.     

Relationship between job control,work pressure and strain: Studies in the USA and in The Netherlands

The purpose of this study was to test a model of job control, work pressure and strain in two samples in the USA and in The Netherlands. According to the proposed model, work pressure has a mediating role between job control and worker strain. The present model specifies three types of job control: task or instrumental control, conceptual or resource control, and decision organization control. Task and resource control are assumed to reduce the stressor of work pressure which, in turn, is related to high strain. Organization control is assumed to be positively related to work pressure. The model was tested in two samples : one US sample of 273office employees and one Dutch sample of 958 employees in a variety of jobs. The same measure of job control was used in both samples. Resultspartially confirm the proposed model. As predicted by the proposed model, high task control was related to low work pressure, whereas high organization control was related to high work pressure. The effects of task control and organization control on strain were mediated by work pressure for the measure of anxiety in the US sample and for the measure of stress in the Dutch sample. However, the mediating effect of work pressure was not found for job satisfaction in both samples, for the measure of mood disturbances in the US sample and for the measure of sick days in the Dutch sample. The proposed model is only partially confirmed by the results. These results confirm the importance of differentiating between different dimensions of job control.     

Work and mental disorders in a German national representative sample

Abstract

Most previous studies concerning the associations between work and mental ill-health have used dimensional self-report questionnaires for mental health problems (e.g., depressive symptoms). This study contributes to occupational health research by providing standardized clinical diagnoses based on DSM-IV criteria. A total of 2329 employees (age 18–65 years) took part in a structured, computer-assisted clinical interview (DIA-X/M-CIDI). Further, they specified whether their job was characterized by physical workload, overtime, or stress, and evaluated whether they feel impaired by each job characteristic. Results show that substance abuse/dependence (including nicotine dependence) was the highest prevalent mental disorder in German employees (12 month prevalence: 14.4%; only alcohol and illicit substance abuse/dependence: 4.9%) followed by anxiety (12.0%) somatoform (9.7%), and affective (9.3%) disorders. Sequential logistic regression analyses showed significant associations between the presence of stress at work and affective and somatoform disorders. Furthermore, feeling impaired by stress at work was strongly associated with anxiety, affective, somatoform disorders, and substance abuse/dependence. Beside work, personal characteristics, primarily gender, were associated with mental disorders in employees. However, except for affective disorders, gender did not modify the association between job characteristics and mental disorders. Taken together, results corroborate the necessity of considering mental disorders at work. Further studies to define the relation between work and mental disorders in employees are strongly recommended and should include objective analyses of job characteristics.     

Recovery experiences as moderators between psychosocial work characteristics and occupational well-being

Abstract

This study examined the direct and moderator roles of recovery experiences (psychological detachment from work, relaxation, mastery, and control) in the relationship between psychosocial work characteristics (i.e. time demands, job control, and justice of the supervisor) and occupational well-being (need for recovery, job exhaustion, and work engagement). The study was conducted among 527 Finnish employees from several occupational sectors who were employed in a variety of different jobs. Of the employees, 53% were women and the average age was 42.4 years. The moderated hierarchical regression analyses showed that psychological detachment and mastery were protective mechanisms against increased need for recovery in a situation of lack of job control. Also, relaxation protected against increased job exhaustion under high time demands. In addition, recovery experiences – psychological detachment and mastery in particular – had direct links to occupational well-being. Altogether, the study findings suggest that recovery experiences play a significant role in maintaining well-being at work.     

Work hours and well-being: The roles of work-time control and work-family interference

This study focused on mediating and moderating processes underlying the relationship between work hours and well-being. Questionnaire data from 292 female employees in two UK public sector organizations were analysed. Drawing on effort-recovery theory and published empirical findings, it was hypothesized that work-family interference (WIF) would mediate the relationship between work hours and measures of well-being (psychological distress and family satisfaction), and that work-time control would moderate the association between work hours and WIF. Hierarchical regression analyses showed that, after controlling for demographic variables, neuroticism, and job demands, WIF mediated the effect of work hours on family satisfaction, although no evidence of mediation was found for the psychological distress outcome measure. Work-time control moderated the relationship between work hours and WIF; higher control buffered the effect of longer hours on WIF. These findings add to the literature on the role of WIF in the effort-recovery process by showing that longer work hours are not necessarily associated with higher work-family interference, and hence with poor recovery and impaired well-being. Instead, having a degree of control over work hours moderates the first link in this process. Thus, the provision by employers of some flexibility and control over work hours may help to reduce the potential negative impact of long work hours on employees.     

Knowledge and Risk Perception Among Nuclear Power Plant Employees

This is a study of knowledge, risk perception, and attitudes among nuclear power plant employees. A total of 236 persons participated, belonging to 10 different professional groups and working at two Swedish power plants. Job-related radiation risks were judged about average as compared to a number of other risks. On the whole, the participants in the study were satisfied with the measures of safety at work, but there were some exceptions to this rule, especially among those hired for temporary jobs through external contractors. The experience of job-related radiation risks was related to the level of knowledge about radiation and its risks: those who knew less experienced larger risks. General level of anxiety did not correlate with risk perception. The latter was accounted for mainly by perceived radiation risks. Job satisfaction was more strongly related to perceived conventional job risks than to nuclear risks. Risk ratings were related to how subjects defined the concept of risk. Those who stressed consequences as part of their risk definition gave higher risk ratings.     

The distinction between work pace and working hours in the measurement of quantitative demands at work

During recent years many researchers have criticized the widely used scales on psychological job demands. For instance, they comment that in most cases different types of demand seem to be mixed in one measure. In this paper we analyse the scale on quantitative job demands in the recently developed Copenhagen Psychosocial Questionnaire (COPSOQ), with special emphasis on Differential Item Functioning (DIF). DIF refers to basic differences between groups of respondents, which may affect how they respond to questionnaire items. The data material for our study comprised a representative sample of Danish employees. The respondents were categorized into 32 specific jobs according to the International Standard Classification of Occupations (ISCO 1968). We analysed DIF with respect to the respondents' jobs with logistic regression analyses. These analyses showed that the items used in the original demand scale functioned very differently for different jobs in the population. The conclusion is that scales on quantitative demands are very sensitive to the choice of specific items. If many items on fast work pace and tempo are included in a scale, a number of blue-collar jobs will be identified as high-demand jobs. If, on the other hand, many questions on long working hours and overtime are included, the use of the scale will result in an entirely different picture. This issue has so far received little attention in occupational health psychology. The results have wide theoretical and methodological implications for research on quantitative job demands.
