Job insecurity in managers: Antecedents and consequences

To date, popular accounts and systematic studies of the effects of job insecurity have focused exclusively on firms in acute crisis. In contrast, this study examines perceptions of the reactions to insecurity as a chronic, ambiguous threat. None of the 1291 managers surveyed was currently facing layoff, but half worked for firms that had laid off managers in the previous five years and half worked in a stable, expanding firm. As in previous studies, concern about any aspect of job insecurity was associated with decreased personal well-being and deterioration of work behavior and attitudes. However, only a small minority of managers were seriously worried about imminent job loss, with substantially more anxious about a deterioration in working conditions and long-term security.     

Antecedents and consequences of basic versus career enrichment benefit satisfaction

Using a sample of 250 medical technologists (MTs) over a four‐year time period, this study presents initial evidence for differentiating two different facets of benefit satisfaction—basic and career enrichment. Basic benefit satisfaction exhibited stronger relationships to subsequent general benefit satisfaction, organizational withdrawal intent, and turnover behavior, while career enrichment benefit satisfaction exhibited a stronger relationship to subsequent affective organizational commitment.

Antecedents of organizational commitment across occupational groups: A meta-analysis

This meta-analysis examines whether the relationships between organizational commitment (OC) and its antecedents differ across occupational groups. Two models representing different antecedents are proposed: the member model, presented by the personal variables, and the organization model, presented by role related, structural and work experiences variables. The study is based on 98 samples with correlational data for the relationships between OC and its antecedents. The total sample was divided into two main occupational groups: white collar employees, subdivided into professionals and nonprofessionals, and blue collar employees. The findings reveal that in general the relationship between OC and personal antecedents, representing the member model, is stronger for blue collar and nonprofessional white collar employees than for professional employees. For the role-related, structural, and work experiences antecedents, representing the organization model, differences among the occupational groups were found to be less consistent. In general, the findings demonstrate that the member and the organization model operate differently for varying occupational groups. The findings are discussed in terms of the need for elaboration of the existing explanations for the development of OC.     

The teacher stress process: A cross-cultural analysis

A cross-cultural systems analysis was performed on teacher stress data from Canada and Sweden. The LISREL structural analysis was based on a conceptual model adapted from Kyriacou and Sutcliffe. Although the LISREL solution did not reach statistical significance it was concluded that the conceptual model in the essential features was corroborated by the LISREL analyses. Measurement errors, as well as the sensitivity of the used goodness of fit test (chi square) to the size of the samples was put forward as explanations of the failure to reach statistical significance for the LISREL structural solutions. Furthermore, it was argued that the heterogeneity of the teachers with respect to the stages of their professional careers should be considered in further research on teacher stress, to be able to capture the process aspects more adequately.     

Organizational and behavioural consequences of uncertainty: A case study

This paper examines some of the organizational and behavioural consequences of uncertainty through consideration of a case study. An industrial firm and its problems are described and an attempt is made to understand the origins of the situation using a systems analysis which draws on constructs from the structural, the behavioural and the ‘bureaucratic’ traditions within organization theory. The analysis demonstrates: that the problems are interrelated and stem from the structural arrangements in the firm which are unable to cope with the prevailing uncertainties; that the behavioural difficulties may be seen as manifestations of the underlying structural/environmental mismatch; and, that the problems are exacerbated by apparently logical but paradoxically inappropriate managerial choices and responses. The implications of this study for theory, practice and method are discussed.     

Organizational exit pressures and role stress: Impact on mental health

Hypotheses regarding role stress, chronic burden and two forms of vulnerability to mental health symptoms are tested in a longitudinal sample of 590 caregivers working in group homes for the mentally ill. In addition, an organizational exit pressure hypothesis is offered. Measures of exit pressure are identified and incorporated into predictive models of stress and mental health. Exit pressures affect somatization directly and interact with role ambiguity to affect subsequent levels of anxiety and somatization. The results suggest that selection pressures in and out of social settings should be conceptualized as part of models of stress and mental health.     

Role stress,physical symptomatology,and turnover intentions: A causal analysis of three alternative specifications

Causal relationships involving role stressors, physical symptomatology, and turnover intentions were examined within three alternative specifications. These specifications stemmed from Beehr and Newman's (1978) and Schuler's (1982) models of role stress and Locke's (1976) theory of job satisfaction. The results, derived from LISREL VI analyses, indicate that a revised Schuler model is the most plausible specification. Findings are discussed in terms of implications for understanding role stress and employee withdrawal.     

Organizational socialization: A stress perspective

This paper examines socialization and adjustment processes of newcomers to organizations. While scholars in this area agree that the socialization process is a stressful event, few have empirically approached the process from this perspective. In addressing this problem, a theoretical synthesis of the literatures of organizational socialization and organizational stress is proposed. From this integration, a model is developed which facilitates an examination of the task, role, and interpersonal demands which individuals face in the stages of socialization and an analysis of the interrelationships of these demands and their effects upon individual and organizational outcomes of the socialization process. Finally, directions for future research are proposed for extending understanding of this crucial part of organizational entry.

Effects of perceived power of supervisor on subordinate stress and motivation: the moderating role of subordinate characteristics

This study examined the moderating effects of subordinate individual differences, specially self‐esteem and locus of control, on the relationships between perceived supervisor power and subordinate motivation and stress. Results showed that perceived supervisor power was more strongly related to increased motivation and decreased stress for subordinates with low self‐esteem than for those with high self‐esteem. For locus of control, perceived reward, coercive and referent power were more positively related to motivation, and legitimate, expert and referent power were more negatively related to stress for externals than for internals. On the other hand, supervisor expert power and legitimate power were positively associated with increased motivation for internals, but not for externals. Implications for future research and practising managers are discussed. Copyright © 1999 John Wiley & Sons, Ltd.     

A role and expectancy model of participative decision-making: A replication and theoretical extension

Schuler's process model of employee participation in decision-making and job satisfaction (Schuler, 1980; Lee and Schuler, 1982) was tested using a path analytic approach. Reanalysis of Schuler's data and replication on a new sample indicated that (a) participation in decision-making has both direct and indirect effects on job satisfaction; and (b) performance–outcome expectancy, role conflict, and role ambiguity all appear to mediate the relationship between participation and satisfaction. In an extension of the model, organizational level and job involvement were hypothesized to moderate the participation–satisfaction relationship (i.e. function interactively). Although neither variable functions as a moderator, job involvement operates in a fashion similar to participation in the model. In general, consistent results across four independent samples strongly support Schuler's basic process model.     

Work-home conflict among nurses and engineers: Mediating the impact of role stress on burnout and satisfaction at work

Using structural equation modeling, this paper compares a more traditional, unmediated model of work-based role stress and its consequences on job satisfaction and burnout to two models in which the role stress-affective work outcome relationship is mediated (partially and completely) by work-home conflict across two samples of public sector professionals: engineers and nurses. The findings indicate that a model in which role conflict and overload have both direct and indirect effects—via work-home conflict—on job burnout and satisfaction (‘Partial Mediation’ model) achieves a better overall ‘fit’ than two alternative models. Furthermore, the findings suggest that while the two groups perceive many aspects of the work-home relationship differently, for both groups, work-based role conflict is an important antecedent of work-home conflict, and increased burnout an important direct consequence of work-home conflict. Finally, on the basis of the findings, the authors conclude that perspectives which view the work and non-work realms as independent must be reconsidered, and that the nature of the work-home relationship may, to a great extent, be contingent upon the way different occupational groups perceive their work situations.     

Underage drinking: frequency, consequences, and interventions

OBJECTIVES: To examine the frequency of underage drinking, driving after drinking and alcohol-related crashes, trends in these behaviors, and promising interventions. METHODS: We examined drinking and drinking- and-driving behaviors reported in the United States in the 2001 U.S. National Household Survey of Drug Abuse, the Centers for Disease Control and Prevention 2001 Youth Risk Behavior Survey, the 1992 National Longitudinal Alcohol Epidemiologic Study, and the 1999 National Survey of Drinking and Driving conducted for the National Highway Traffic Administration. We also examined the 1999 European School Survey Project on Alcohol and Other Drugs. Alcohol-related fatal crashes were examined from the U.S. Fatality Analysis Reporting System. Evaluation of interventions to reduce teenage drinking and driving after drinking were reviewed. RESULTS: In the United States, 19% of youth ages 12-20 consumed five or more drinks on an occasion in the past 30 days. Although European nations have lower legal drinking ages (16-18) than in the United States (21), similar proportions engage in underage drinking. In two-thirds of European countries, a greater percentage of 15-16 year-olds drank five or more drinks on an occasion in the past month than in the United States. In both the United States and Europe, the earlier people begin to drink, the greater the likelihood of developing alcohol dependence and other alcohol-related problems, including alcohol-related crash involvement, during adolescence and adult years. During the past 20 years alcohol-related traffic deaths among people younger than 21 have been cut in half in the United States, but progress has halted since 1995 and the problem is still large. Interventions shown by research to reduce alcohol-related crashes among youth include raising the legal drinking age to 21, zero tolerance laws, and some interventions that are family, school, or community based. CONCLUSIONS: Despite research showing that a variety of interventions can reduce underage drinking and alcohol-related crash fatalities, the frequency of these behaviors remains high and the average age of drinking initiation is declining in the United States. Efforts are needed to enhance publicized enforcement of underage drinking laws. Comprehensive community interventions that include enforcement of these laws also are needed.     

Facilitating and inhibiting effects of job control and social support on stress outcomes and role behavior: a contingency model

High levels of job control and social support are often related to effective job performance and coping with work stressors. However, support may have more positive effects on role behavior when job control is low. In addition, despite theoretical expectations, simple demands–control and demands–support interactions are infrequently found to predict health and psychological strain outcomes. The ‘demands–control–support’ model (Johnson and Hall, 1988) of stress coping integrates these ‘stress buffering’ and ‘decision latitude’ models and observes more consistent findings. This model posits that social support buffers the adverse effects of high demand, low control jobs. However, explicit tests of the interaction of these variables suggest that control can have positive or negative effects on strain, depending on the level of social support. In this study, supervisor consideration was positively related to subordinate job performance, extra-role behavior, and in-role prosocial behavior (conscientiousness) among subordinates perceiving low job control. The relationship between consideration and performance and extra-role behavior was negative among high control subordinates. The demands×control×support interaction predicted health symptoms, organizational commitment, supervisor satisfaction, and absence due to illness, but the interaction plots do not support the prevailing perspective that support buffers the effects of ‘high strain’ (i.e. low control, high demand) jobs. Patterns were similar for different demands and different social support loci (i.e. supervisor, co-workers). An alternative theoretical process of the demands–control–support interaction is proffered, and implications for organizational intervention are discussed. © 1998 John Wiley & Sons, Ltd.

The consequences of organizational commitment: Methodological investigation

Extensive research on the consequences of organizational commitment (OC) has been conducted over the past decade. The purpose of this paper is to summarize empirical evidence about the relationship between OC and work outcomes and to examine the effect of methodological decisions on the OC–work outcome relationship. A meta-analysis of 35 studies of the OC–work outcome linkage reveals that the overall empirical relationship between OC and outcome variables is generally weak, but positive. While subgroup analyses reveal that conceptualization, research design, sampling, operationalization and observation technique decisions have a definite impact on the OC–work outcome correlation, the relationship remains essentially weak. Multiple regression analysis reveals that the type of work outcome and methodological decisions explain only 19 per cent of the variance in the OC–work outcome relationship, with conceptualization decisions having the largest impact.
