The impact of job demands and behavioral control on experienced job stress

The present study examines the impact of behavioral control on the experience of work strain under conditions of work overload. Extending experimental laboratory findings that suggest that control can lessen the impact of aversive stimuli on psychological and physiological strain responses, we hypothesized an interaction between control and workload such that the effects of high demands on strain would be less if the worker had behavioral control over the task. This hypothesis is also consistent with Karasek's job demands-job decision latitude model of work strain and health. The hypothesis was tested in a laboratory experiment in which 125 subjects worked on a mail sorting task with either a high or moderate level of workload and either a high or low level of behavioral control. Strain responses were assessed with measures of job satisfaction, anxiety, and physiological arousal. The hypothesis was only partially supported in that high control lessened the impact that work overload had on anxiety. While not fully supportive of the model, the results are seen as conservative given the constraints on the manipulation of work overload inherent in the laboratory environment.     

Intra‐individual variability in job complexity over time: Examining the effect of job complexity trajectory on employee job strain

Drawing on gestalt characteristics theory, we advance the literature on the effect of job complexity on employee well‐being by considering intra‐individual variability of job complexity over time. Specifically, we examine how the trend, or trajectory, of job complexity over time can explain unique variance of employee job strain. Across two longitudinal data sets, we consistently find that, with the average level of job complexity during a given period held constant, a positive job complexity trajectory (i.e., an increasing trend in complexity) is associated with higher employee job strain. Based on job‐demand‐control theory and the exposure‐reactivity model, we further establish that job autonomy and employee emotional stability jointly moderate the relationship between job complexity trajectory and employee job strain. Specifically, for employees with high emotional stability, job autonomy mitigates the job strain brought by positive job complexity trajectory, whereas for employees with low emotional stability, job autonomy does not help to reduce the adverse effect of the increasing trend. These findings not only contribute to extend the understanding of the job complexity – strain relationship, but also suggest a promising, dynamic avenue to study the effects of work characteristics on employee well‐being as well as other outcomes.

Psychological ownership within the job design context: revision of the job characteristics model

In this paper, we offer a theoretical modification to the Hackman and Oldham (1975) Job Characteristics Model by integrating research on the psychological aspects of job design with emerging theory on psychological ownership. We develop the connection between job design and (a) the motives facilitating psychological ownership, (b) the routes through which psychological ownership emerges, and (c) the individual‐level outcomes (e.g., emotional, attitudinal, motivational, and behavioral) that result from an employee's psychological ownership of his or her job. Our work covers several previously ignored positive and negative effects. We conclude by positioning psychological ownership as a plausible substitute for other proposed mediating psychological states in the job design–employee response relationship.

The derivation of job designs

This paper presents a theoretical account of the derivation of job designs incorporating consideration of technology, structure and managerial control, viewed from an information processing perspective. A conceptual distinction is made between tasks and roles which has practical relevance in that organizations have independent choices regarding their design. These choices are underpinned by economic and psychological values as well as by managerial needs for control. The paper argues that whilst options exist, organizations typically choose to simplify jobs, a strategy which may well be ineffective, especially under conditions of uncertainty. New, more complex job designs may be very difficult to implement for economic, psychological, managerial and political reasons. Research and development should now be directed towards a more detailed cognitive and social psychological understanding of the derivation and impact of job designs as well as towards study of the introduction and impact of new technology. These represent qualitative shifts in research emphasis.     

The effect of job and environmental factors on job satisfaction in automotive industries.

A methodology was developed for diagnosing industrial work, which includes questionnaire, observation, measurements, data collection and statistical analysis. A survey was conducted to investigate the relationship between job satisfaction and factors that affect work design in 2 automotives manufacturing companies in Malaysia. A basic work design model was proposed. The aim of this model was to determine the factors that influence employees' perception towards their work. A set of multiple-choice questionnaires was developed and data was collected by interviewing employees at a production plant. The survey focused on job and environmental factors. The results supported the proposed model and showed that job and environmental factors were significantly related to job satisfaction. They highlighted the significant influence of age, work experience and marital status on job satisfaction. Further, environmental factors, especially the surroundings, context dependence and the building's function, also had a significant impact on job satisfaction.     

The measurement of job control

Subjective or perceived control over job-related activities or events is a frequently measured construct in organizational stress research. Karasek (1985) assessed perceived control as both decision authority and skill discretion at work (job decision latitude). Ganster (1989b; Dwyer and Ganster, 1991) developed a multidimensional or general measure of worker control, as well as a specific measure of work predictability. Because little published psychometric data exist for these scales, we investigated the item-level measurement properties of Karasek's and Ganster's measures. We hypothesized two separate, two-factor solutions, decision authority and skill discretion, for the job decision latitude scale, and general control and predictability, for the work control scale. The dimensionality of both measures was assessed in multiple, independent samples using confirmatory factor analyses (LISREL) with maximum likelihood estimation. Simultaneous solutions across samples were used to determine the fit of the factor models to the data. The hypothesized two-factor solutions were confirmed for both Karasek's and Ganster's scales, although item refinement is indicated. We also investigated the relative independence between Karasek's and Ganster's scales and found a lack of independence between the general control and decision authority items in one sample. © 1997 John Wiley & Sons, Ltd.     

Occupational embeddedness and job performance

While researchers have recently focused their attention on organizational embeddedness, occupational embeddedness has received little theoretical and empirical attention. Using multisource data on 162 employees in multiple jobs and organizations, we found that occupational embeddedness is positively related to both task performance and creativity and is negatively related to counterproductive work behavior, even after controlling for the effects of organizational embeddedness. In addition, we found that trait affect moderated the relationships of occupational embeddedness to job performance. Occupational embeddedness was more strongly related to counterproductive work behavior when trait negative affect was high, while occupational embeddedness was more strongly related to both citizenship behavior and creativity when trait positive affect was high. Results also indicated that the various components of occupational embeddedness had different effects on job outcomes. Fit had a strong positive effect on core task performance, links had a positive effect on creativity, and sacrifice had a small positive effect on citizenship behavior. The article concludes with a discussion of implications for future research and management practice. Copyright © 2009 John Wiley & Sons, Ltd.     

Hassles on the job: a study of a job intervention with urban bus drivers

Epidemiological, psychophysiological and survey data all converge on the conclusion that driving a bus in an urban area is extremely stressful, posing serious health risks. We show that reductions in job hassles while operating buses largely account for the salutary effects of a job environment intervention designed to lessen traffic congestion, diminish passenger demands on drivers, and generally ease bus operation. This study also makes methodological contributions to the stress and health literature. Independent observers' assessments of changes in job hassles caused by a field intervention predict, in a longitudinal design, multimethodological markers of stress including blood pressure, heart rate, and a standardized self‐report index of stress. The value of utilizing job re‐design studies to more rigorously investigate stress and health is discussed. Copyright © 1999 John Wiley & Sons, Ltd.     

Reorienting job crafting research: A hierarchical structure of job crafting concepts and integrative review

Two dominant perspectives of job crafting—the original theory from Wrzesniewski and Dutton ( 2001 ) and the job demands resources perspective from Tims, Bakker, and Derks ( 2012 )—remain separate in research. To synthesize these perspectives, we propose a three‐level hierarchical structure of job crafting, and we identify the aggregate/superordinate nature of each major job crafting construct. The first level of the structure is job crafting orientation, or approach versus avoidance crafting, which we argue is an essential yet often neglected distinction in the literature. We address the debate surrounding cognitive crafting and identify crafting form (behavioral versus cognitive crafting) as the next hierarchical level of constructs. Finally, we concur that job resources and job demands, or crafting content, capture different ways that individuals craft their jobs. Using this integrated hierarchical structure, we were able to review antecedents and outcomes from both perspectives. We show, for example, that approach crafting in its behavioral form is very similar to other proactive behaviors in the way it functions, suggesting a need for closer synthesis with the broader proactive literature, whereas avoidance crafting appears to be less proactive and often dysfunctional. On the basis of our review, we develop a road map for future research.     

Occupational stress in (inter)action: the interplay between job demands and job resources

The present study addresses theoretical issues involving different interaction effects between job demands and job resources, accompanied by a thorough empirical test of interaction terms in the demand–control (DC) model and the effort–reward imbalance (ERI) model in relation to employee health and well‐being (i.e., exhaustion, psychosomatic health complaints, company‐registered sickness absence). Neither the DC model nor the ERI model gives a clear theoretical rationale or preference for a particular interaction term. Hierarchical regression analyses were conducted among 405 nursing home employees and cross‐validated in a comparable sample (N = 471). Results including cross‐validation showed that only a multiplicative interaction term yielded consistent results for both the DC model and the ERI model. Theoretical as well as empirical results argue for a multiplicative interaction term to test the DC model and the ERI model. Future job stress research may benefit from the idea that there should be a theoretical preference for any interaction form, either in the DC model or in the ERI model. However, more research on interactions is needed to address this topic adequately. Copyright © 2005 John Wiley & Sons, Ltd.     

The job satisfaction of older workers

Older workers re-entering the workforce and those changing jobs are coming to play an increasingly important role in the labor force, especially as part-time workers. Yet the work orientation and job satisfaction of these workers has not been studied. Do ‘situational’ factors such as skill and pay matter for this subgroup of workers, and if so, which ones? If significant factors exist, can their effect be explained by the mediating influence of ‘dispositional’ factors like work values? This paper explores these questions in a study of 198 older workers who had begun new, mostly part-time jobs. Regression analysis shows that the intrinsic indicators for skill and autonomy have a positive effect on job satisfaction. No extrinsic factor was significantly related to satisfaction, indicating that these workers are more than ‘instrumentally’ oriented. This support for a ‘situational’ interpretation of the impact of work, especially intrinsic features, was sustained in analyses which incorporated work values. To the extent that the growing number of part-time jobs are relatively low-skilled, and to the extent that older workers in new jobs are influenced most by intrinsically rewarding work, there appears to be a growing mismatch between an occupational niche and those who are being sought to fill it.     

Individual demographic differences and job satisfaction

Empirical research and theoretical literature support the notion that demographic differences among employees are associated with job satisfaction. However, the evidence is inconsistent, and little is known about the stability of many of the reported relationships. A meta-analysis was conducted involving 21 independent studies and over 10,000 employees to discern selected population relationships. Results indicated that, with the exception of age and organizational tenure, associations do not differ significantly from zero. Large amounts of variance around each mean correlation, however, warranted a moderator analysis. Results indicated that the strength and pattern of associations differ by organizational type. Theoretical propositions and implications for future research in the area of demographic moderators are discussed.     

Sex differences in job attribute preferences

This study investigated the job attribute preferences of male and female MBA candidates. Participants were drawn from 27 different MBA programmes in the United States. Factor analysis of the job attributes questionnaire revealed three primary job attribute dimensions: (1) professional growth; (2) work environment; and (3) salary. Contrary to most previous research, females were found to place a greater emphasis on the professional growth dimension than did males. Males, on the other hand, placed greater emphasis on salary considerations. No sex difference was found in participants' ratings of the work environment job attribute dimension. Consistent with earlier research, women were found to place more importance on the calibre of colleagues than did males. In general, both males and females rated job attributes concerning job content as more important than job attributes concerning job context. These results are discussed with respect to earlier research findings. Finally, the generalizability of these findings to other occupational groups is discussed and managerial implications presented.     

The justice perspective of job stress

The study presents a new variable, role justice, pertaining to the perceived fairness of role senders reaction when the focal individual is under conflict, ambiguity, overload, or restricted latitude. The effect of this variable on symptoms of strain was explored, with the expectation of finding either additive or interactive effects vis-à-vis the above four role stressors. Using hierarchical multiple regression, the data supported the additive model which suggested that role injustice constitutes an additional source of stress. The study was conducted with a sample of hospital nurses, known to have significant levels of job stress. The results suggest that the role stress model ought to be expanded to include social appraisal constructs because of the social origin of the stressor variables it deals with.     

The mediating role of job characteristics in job redesign interventions: A serendipitous quasi‐experiment

The aim of this paper is to examine the mediating role played by five key job characteristics in the relationship between employee participation in a job redesign intervention and employee well‐being. In studies of job redesign interventions, it has been assumed that any effects of employee participation in job redesign on well‐being are a result of changes in job characteristics rather than participation in change per se. It is therefore important to statistically test for mediation in job redesign intervention studies to help establish that the change in job characteristics is the mechanism through which job redesign interventions work. However, this has rarely been tested directly, either because data to allow tests of mediation have not been collected (e.g. assessments of job characteristics) or because data have been collected but mediation has not been tested using accepted procedures. This makes it unclear whether changes in job characteristics explain the effects. Results from multilevel analyses of a longitudinal 9‐month long serendipitous quasi‐experimental participative job redesign intervention showed that changes in job control, participation, skill utilization and feedback, but not task obstacles, were sufficient to account for the relationship between the intervention and employee well‐being.

Employee's turnover intentions and job destination choices

Employee's job destination choices, as part of the turnover process, reflect options for internal organizational or external labor market moves. A sample of 477 employees in 15 firms was used to decipher how bio‐demographic, job, plant, and labor market characteristics are related to five alternative job destinations. Multivariate logistic regression and odds–ratio analyses compared the five models confirming that different sets of variables influence each of the destination choices. Coworkers' intentions have a major significant impact on all destination options. The findings have implications for present turnover models, career paths, and promotion progression in the firm.
