Is it worth it? Linking perceived high-performance work systems and emotional exhaustion: The mediating role of job demands and job resources

The present study utilizes the job demands–resources model and examines the effects of employees’ perceptions of high-performance work systems (HPWS) on emotional exhaustion. For the needs of this study, structural equation modeling (SEM) was used on a sample of 343 frontline employees in a Greek manufacturing company. The findings do not support the critical arguments regarding HPWS, which suggest that these systems lead to work intensification and emotional exhaustion through increased job demands. In contrast, HPWS was positively related to job resources, although no support was found for a direct and negative relationship with emotional exhaustion. Last but not least, this study calculates HPWS as both a system and bundles of practices and provides useful insights regarding the differences between the two different measurement methods. Finally, theoretical and managerial implications are drawn for improving our understanding of how HPWS influences job demands and resources and employees’ emotional exhaustion.     

The Job Demand-Control (-Support) Model and psychological well-being: a review of 20 years of empirical research

The Job Demand-Control (JDC) model (Karasek, 1979) and the Job Demand-Control-Support (JDCS) model (Johnson, and Hall, 1988) have dominated research on occupational stress in the last 20 years. This detailed narrative review focuses on the JDC(S) model in relation to psychological well-being. It covers research from 63 samples, published in the period 1979-1997. In the review a distinction is drawn between two different hypotheses prevailing in research on the models. According to the strain hypothesis of the JDC model, employees working in a high-strain job (high demands-low control) experience the lowest well-being. The buffer hypothesis states that control can moderate the negative effects of high demands on well-being. Translating these hypotheses to the expanded JDCS model, the iso-strain hypothesis predicts the most negative outcomes among workers in an iso-strain job (high demands-low control-low social support/isolation), whereas the buffer hypothesis states that social support can moderate the negative impact of high strain on well-being. Although the literature gives considerable support for the strain and iso-strain hypotheses, support for the moderating influence of job control and social support is less consistent. The conceptualization of demands and control is a key factor in discriminating supportive from nonsupportive studies. Only aspects of job control that correspond to the specific demands of a given job moderate the impact of high demands on well-being. Furthermore, certain subpopulations appear to be more vulnerable to high (iso)strain, whereas others benefit more from high control. On the basis of the results of this review, suggestions for future research and theoretical development are formulated.     

What You Know or Who You Know? Occupation-specific work experience and job matching through social networks

While work experience is generally seen as an indicator of human capital, it may also reflect the accumulation of social capital. This study examines how work experience facilitates informal access to employment—that is, being matched with a new employer through an informal search or informal recruitment through the non-search process (without engaging in a job search). Results from fixed effects regression on panel data from the NLSY show that experience is related to informal entry into new jobs, though in a very specific way. The odds of being informally recruited into a new job improve as work experience in related occupations rises, but this relationship holds only among men. These findings highlight the social benefits of occupation-specific work experience that accrue to men but not to women, suggesting an alternative explanation for the gender disparity in wage returns to experience.

Replanning the Master Production Schedule for a Capacity-Constrained Job Shop

This research examines the use of both frozen and replanning intervals for planning the master production schedule (MPS) for a capacity-constrained job shop. The results show that forecast error, demand lumpiness, setup time, planned lead time, and order size have a greater impact on the mean total backlog, total inventory, and number of setups than the frozen and replanning intervals. The study also shows that a repetitive lot dispatching rule reduces the importance of lot sizing, and a combination of repetitive lot dispatching rule and single-period order size consistently produces the lowest mean total backlog and total inventory. The results also indicate that rescheduling the open orders every period produces a lower mean total backlog and total inventory when the forecast errors are large relative to the order sizes. This result suggests that the due date of an open order should be updated only when a significant portion of the order is actually needed on the new due date.

RFID as an Enabler of Improved Manufacturing Performance*

The use of radio frequency identification (RFID) versus bar coding has been debated with little quantitative research about how to best use RFID's capabilities and when RFID is more advantageous. This article responds to that need by qualitatively and quantitatively analyzing how RFID facilitates increased traceability and control in manufacturing, which in turn enables the use of more lot splitting and smaller lot sizes. We develop insights about operating policies (RFID vs. bar‐code tracking mechanisms, extent of lot splitting, and dispatching rules) and an operating condition (setup to processing time ratio) that affect the mean flow time and proportion of jobs tardy in a job shop. A simulation model is used to control factors in the experimental design and the output is evaluated using analysis of variance. The results show the following: (i) performance worsens when bar coding is used with extensive lot splitting, (ii) process changes such as extensive lot splitting may be required to justify RFID use instead of bar coding, (iii) the earliest operation due date dispatching rule offers an attractive alternative to other rules studied in previous lot splitting research, and (iv) the performance improvements with RFID and increased lot splitting are larger when the setup to processing time ratio is smaller. In a broader context, we fill a research void by quantitatively showing how RFID can be used as an advanced manufacturing technology that enables more factory automation and better performance along several dimensions. The article concludes by summarizing the results and identifying ideas for future research.

Fit for Work? The Influence of Sick Pay and Job Flexibility on Sickness Absence and Implications for Presenteeism

Recent developments in UK policy on health and employment have sought to change perceptions about what constitutes ‘fitness for work’. With the aim of reducing the incidence and duration of sickness absence, a range of initiatives, including the introduction of the ‘fit note’, are challenging the belief that it is necessary to be 100 per cent well in order to be at work. However, this article suggests that contextual factors independent of health may also influence people's decisions about whether or not to attend work at times of reduced wellness. Drawing upon data from a qualitative study of mental health and employment, this article illustrates how the terms and conditions of a person's employment may influence sickness absence decisions in a number of ways. It is argued that sick pay provisions, size of employer and nature of work may influence both decisions to take time off and decisions about when to return to work. The degree of flexibility to manage one's workload around times of poorer health may also have a bearing on whether people feel able to carry on with their work without recourse to sickness absence. Therefore, it may be important for policy interventions to consider not only health circumstances but also structural/contextual influences on conceptualizations of being ‘fit for work’. The implications of such contextually‐influenced decision‐making for ‘presenteeism’ are also considered. It is suggested that current conceptualizations of presenteeism are somewhat ambiguous; employees coming to work despite ill health is simultaneously presented as a problem and an aspiration.
