Modelling relationships between job stressors and injury and near-miss outcomes for construction labourers

Construction work is an inherently dangerous occupation and exposure to additional job stressors is likely to exacerbate the level of danger, increasing workers' risk for injury. Thus, it is important to identify and then reduce worker exposure to extraneous job stressors. This study examines the relationships between a variety of job stressors and injury or near-miss outcomes among construction workers. Self-reported questionnaire data collected from 408 construction labourers (male and female) via telephone interview were analysed using structural equation modelling. A theoretical model was tested whereby work stressors, classified into three groups, could be related, either directly or indirectly through the mediating effects of physical or psychological symptoms/strain, to self-reported injuries and near misses. Ten of the 12 work-related stressors were found to be directly related to either injury or near misses, including: job demands, job control, job certainty, training, safety climate, skill under-utilization, responsibility for the safety of others, safety compliance, exposure hours, and job tenure. Other stressors (i.e. harassment/discrimination, job certainty, social support, skill under-utilization, safety responsibility, safety compliance, tenure in construction) were indirectly related to injuries through physical symptoms or indirectly related to near misses through psychological strain. There was no support for the modelled gender differences. Implications for health and safety on construction sites are discussed.

Corporate Profit,Social Welfare,and the Logic of Capitalism

Business ethics scholars have proposed strategies for mitigating the ill effects brought on by a wealth maximization business strategy by urging managers to either embrace corporate social responsibility (CSR) or to manage according to stakeholder theory. In this article I argue that these strategies are often ineffective in bringing about the behavior they promote because it is antithetical to the nature and logic of capitalism. I examine the organizing principles of capitalism and the role it assigns to capitalists, and juxtapose these with the behavior prescribed by three normative frameworks: strategic management theory (SMT), the CSR initiative, and stakeholder theory. Unlike the behaviors prescribed by the CSR initiative and stakeholder management theory, the behavior prescribed by SMT is consistent with the role of capitalists as defined by the organizing principles of capitalism, and SMT's “rules” have instilled habits that have, in turn, been able to mold managers’ aspirations and purposes. CSR and stakeholder theory must not only combat the habits instilled by the entrenched SMT, they must also find some way of instilling habits that run contrary to those defined by the nature and logic of capitalism itself.     

Exploration of the impact of organisational context on a workplace safety and health intervention

ABSTRACT

The Safety and Health Improvement Program (SHIP) was designed to increase workers’ safety and health using supervisor/leadership training. SHIP was implemented and evaluated in a cluster randomized controlled trial with 20 supervisors and 292 construction crew members representing a high-risk industry. The intervention had three components: (1) computer-based training to teach supervisors ways to better support worker safety and work-life challenges; (2) supervisor behavioural self-monitoring to facilitate transfer of training to practice; and (3) team-based discussions with supervisors and work crew members to identify challenges and opportunities for improvement with 30, 60, and 90 day follow-up check-in meetings. Main effects for the intervention on perceptions of family supportive supervisor behaviors, team effectiveness, and work-life effectiveness were not found, suggesting that the pre-intervention context could help explain the lack of intervention effects. We found that the intervention was more beneficial for work crew members who had poorer pre-intervention perceptions of their supervisor (lower leader-member exchange) and lower perceived team cohesion, suggesting the important impact of the organisational context on intervention effects. We argue that perhaps these work crews were more ready for change and improvements in functioning than were the crews that were already functioning well.

Risk Management and Decision Rules for Light Water Reactors

A quantitative approach to risk management for accidents in light water nuclear power reactors is proposed to serve as one focus for discussion. In this proposal risk management is divided into two major tasks: the predominantly social and political task of setting the safety goals and the technical task of estimating the risks and deciding whether the safety goals have been met. The proposed safety goals include limits on the following: risk to the individual of early death or delayed cancer death; overall societal risk of early or delayed death; and the frequency of core melt accidents as well as the frequency of containment failure, given a core melt. Also included are a small element of risk aversion and an "as low as reasonably achievable" (ALARA) approach with a cost-effectviness criterion which includes both economic and health effects.     

Policy Goals for Health and Safety

Health management and safety regulation are separate disciplines but share the aim to extend expectancy of life in good health. The need to improve cost-effectiveness calls for their co-ordinated management according to a unified rationale. Three guiding principles of accountability, demonstrable net benefit and a uniform measure of performance, have been laid out in Canada by the Joint Committee on Health and Safety. They call for open accounting in terms of (health-related quality-adjusted) life expectancy. The principles are utilitarian in format but, it is argued, inequity is naturally diminished in the process of optimizing cost-effectiveness through maximum marginal returns. Comments are made on practical implementation. The need for public consent in practice calls for two additional principles reflecting fair procedure and sovereignty of the citizens. It is concluded that public health and safety measures should be surveyed, documented for cost-effectiveness and prioritized for improvement.     

Is Safe Production an Oxymoron?

This research examines how organizations simultaneously manage their operations and occupational health and safety. Although both safety and operations scholars conduct research in the same operational settings, they have reached different, yet untested, conclusions about the relationship between creating a safe workplace and creating a productive workplace. The results from a series of 10 case studies show that it is possible to create safe and productive workplaces, but that many facilities fail at this task because of problems associated with the culture management creates and the practices management adopts.     

Nurses: Training for new job demands

This paper argues that both the present and future job demands faced by nurses are likely to exceed the resources of the training which is currently provided for them. This argument will be supported by reference to the authors' studies of stress in nursing, as well as a variety of other sources. The common themes underlying reactions to both present and future demands include first, awareness of high stress levels to be found amongst nurses, and second, an emphasis on communication as both the problem and as the proposed solution. Common responses to these two themes are outlined, including training in stress management, and communication training. Some of the problems and unexamined assumptions (for example that hospital management actually wants to lower stress levels and improve communication in nursing) are examined. Some suggestions are made for developing training in health care contexts, to deal more adequately with likely future demands.     

Exploring the Effects of Cultural Variables in the Implementation of Behavior-Based Safety in Two Organizations

Abstract

The present case study examines how culture can influence behavior-based safety in different organizational settings and how behavior-based safety can impact different organizational cultures. Behavior-based safety processes implemented in two culturally diverse work settings are described. Specifically, despite identical implementation plans, similarities and differences in the actual implementation of the two behavior-based safety processes are presented with an emphasis on the effects of employee-driven decisions. Data on both implementations and outcome measures are provided. The results are discussed with respect to the potential impact of specific cultural variables.     

Training and organizational commitment among nurses following industry and organizational change in New Zealand and the United States

This survey study examines the relationship between employee attitudes related to training and organizational commitment among a sample of nurses in New Zealand and the United States. The magnitude of recent restructuring to New Zealand's public health system allows for an examination of employee attitudes towards training and organizational commitment in comparison to nurses from similar sized hospitals in the United States. Results show that perceived access to training, supervisory support for training, motivation to learn from training and perceived benefits of training were positively related to the affective and normative components of organizational commitment. Several significant differences were found on both training and organizational commitment variables between New Zealand and the United States. The findings are discussed in terms of their theoretical and practical application to human resource development (HRD) outcomes and the management of HRD in health care settings.     

Behavioral Self-Monitoring of Safety and Productivity in the Workplace: A Methodological Primer and Quantitative Literature Review

Workplace applications of behavioral self-monitoring (BSM) methods have been studied periodically for over 35 years, yet the literature has never been systematically reviewed. Recent occupational safety interventions including BSM resulted in relatively large behavior changes. Moreover, BSM methods are functional for addressing a broad range of occupational health psychology topics. Studies (n = 24) where workers self-monitored productivity or safety behaviors were reviewed and scored along dimensions relevant to research and practice. For intervention conditions (n = 38), standardized effect sizes ranged from 0.2 to 14.5 (weighted average d = 2.8). The results encourage the use of BSM in workplace interventions, but the literature has insufficiently addressed the isolated and additive effects of BSM, worker involvement and individual differences, assessment applications, and theory testing and development.     

How do you define the health of populations?

What are the perceptions of population health, and how do you define it to move forward on any common action agenda of policy, management, teaching, or research? The author asks a series of questions to clarify the ambiguities around the population health concept, beginning with defining "health" as more than the absence of disease, but less than the breadth of complete well-being. Such a framework requires an operational measure of population health outcome that goes beyond quantity of life (mortality) to add extra dimensions. In other words, the goal is not only to purchase life years, but life years at some level of quality. The article provides an argument for the importance of some aggregate measure of health outcome, such as Health Adjusted Life Expectancy (HALE), as a management tool for purchasing populations health.

Three Principles for Managing Risk in the Public Interest

We propose three principles and a general framework of reasoning for managing risk in the public interest. Principle 1. Risks shall be managed to maximize the total expected net benefit to society— The principle that the net benefit is to be maximized across society as a whole is argued to be a sufficient and rational guide to assessing the effectiveness of efforts directed at reducing risk and thus improving health and safety. The net benefit of an activity is the excess of the totality of benefits over the totality of detriments. Principle 2. The safety benefit to be promoted is life-expectancy— The goal is to ensure that risk mitigation efforts maximize the net benefit to society in the specific terms of length of life for all individuals. The effect of an activity on life expectancy is proposed as the proper basic measure of its net safety impact. Life expectancy is a universal measure valid for comparisons both within and among countries and can be adjusted to include health expectancy and other factors such as income levels that affect the quality of life. The impact on life expectancy allows a dispassionate accounting of the good and the bad inherent in any proposal or activity that is in the public interest but has some impact on life and health. Principle 3. Decisions for the public in regard to health and safety must be open and apply across the complete range of hazards to life and health— Systematic efforts to evaluate all the important consequences, both direct and indirect, are required to improve the basis for risk management in society. Balancing of the detriments and the benefits of any given initiative is the key aspect of the undertaking. Safety may well be an important objective in society, but it is not the only one. Thus, allocation of society's resources devoted to safety must be openly and continually appraised in light of other competing social needs because there is a limit on the resources that can be expended to save lives. Maximization of healthful life for all is judged the proper basis for managing risk in the public interest, and that this is achieved when the net of the contribution to the total saving of life exceeds the loss of life.     

Testing the Vitamin Model of job stress in Dutch health care workers

Three central hypotheses of Warr's Vitamin Model concerning the relationship between job characteristics and well-being and health outcomes were tested: (1) differential effects of job characteristics on the various well-being and health outcomes; (2) predominance of curvilinear associations; and (3) moderate influence of negative and positive affectivity on these relationships. The study participants were 162 employees from a health care organization (aged 19-54 years, 95% women) who completed questionnaires on job demands and job autonomy, as well as on the outcome variables depression, anxiety, job satisfaction, and health complaints. In addition, data on short-term sickness absence were collected. A higher level of job demands was significantly associated with a lower level of well-being and self-reported health. Job autonomy showed weaker relationships with the outcome variables. The effects of job demands were still large after controlling for negative and positive affectivity, while the effects of job autonomy in most cases became non-significant. The predicted curvilinear relationship between job characteristics and outcome variables did not have an additional value over a linear model in predicting the data. It is concluded that the present data from a homogeneous sample of mostly female nurses support Warr's Vitamin Model to a limited extent.

EXCELLENCE AT ROHM AND HAAS KENTUCKY: A CASE STUDY OF WORK-TEAM INTRODUCTION IN MANUFACTURING

Over the past few years we have witnessed a sharp decline in the domestic and international market share of U.S. manufacturing organizations. The decline in U.S. manufacturing has provided an avalanche of criticism and attention in the literature and popular press. Recently, however, several organizations have implemented new work-force management policies to reverse the decline. We describe the case of Rohm and Haas Kentucky, Incorporated, a plant that has implemented work teams. The outcomes of these innovations include a decline in worker grievances and turnover, an improvement in the safety record of the plant, as well as an increase in productivity.     

Behavioral Perspectives on Variability in Human Behavior as Part of Process Safety

ABSTRACT

Process safety involves worker decisions at various points in an extended process, and much remains unknown regarding sources of variability in worker behavior at these decision points. This paper seeks to explain why some workers may be deviating from sanctioned policies and procedures. Risky choice is analyzed through discussion of positive and negative reinforcement, habituation in terms of respondent and operant behavior, risk discounting, and consequence dimensions that include a review of prospect theory, heuristics, and behavioral decision theory. Recommendations are made for improving our understanding of sources of variability in process safety by conducting systematic research on the perspectives reviewed.
