This study addressed some conceptual issues central to understanding human reactions to dangerous settings and empirically explored the meaning of physically dangerous work in three different occupational groups (street patrol officers, n=96; investigators, n=21; and clerical and support service workers, n=60) practicing in the same organizational setting (city police department). Objective hazards, estimated with occupational risk statistics, explained 56 per cent of the variation in experienced physical danger which, in turn, significantly heightened emotional exhaustion, dissatisfaction with pay, and disaffection from the employing organization, in the street patrol officer group only, perceived physical danger significantly correlated with task variety, task significance and feedback. The data are interpreted to mean that for street patrol officers, experienced physical danger adds a modicum of enrichment and significance to the work itself. One theme of the analysis is that potentially stigmatic features of the work can be transformed into socially meaningful illusions that enhance the personal dignity of the performer (cf. Hughes, 1958). However, the dominant theme is that physically dangerous work produces fear and related affective distress. Further research on this topic is recommended because of the affective and behavioral consequences of perceived physical danger and also because definitions and meanings of dangerous work are socially, politically and morally important.

In response to the charge by House and Kahn (1985) that there is lack of specificity in conceptualization and measurement of the social support construct, this paper suggests the need to identify and specifically measure discrete properties of the previously identified dimensions (type and source) of social support. Properties are defined as what it is about combinations of source and type that needs to be measured. Based on literature reviews it is suggested that the relevant properties are amount of support, adequacy of support and number of providers of support. Measures are developed for each property. Data from 186 nurses were used to assess main and moderating effects of social support properties, workload and dying patients on emotional exhaustion and physical symptoms. As predicted, support adequacy was related to perceptions of lower workload. As single predictors, amount and adequacy of support reduced physical symptoms and emotional exhaustion. With amount and adequacy controlled, number of providers increased emotional exhaustion. Amount buffered the relationship between death and emotional exhaustion. Moderate levels of adequacy and number buffered the relationship between workload and exhaustion. Both adequacy and amount of support assisted in coping with patient death. In addition, a number of ‘reverse’ buffering and coping relationships were found. It was concluded that examination of different properties of social support increases our understanding of the impact of social support, and that further research needs to examine the simultaneous effects of various combinations of property, type and source of social support.
