On the importance of knowing the affective meaning of job demands

AbstractTheorizing about the effects of job demands on mental health, job satisfaction and performance can be enhanced by allowing for a more complicated view of job demands. This paper describes an empirical attempt aimed at investigating facets of job demands. It hypothesizes that (1) many individuals will agree that job demands of certain kinds and strengths, will be associated with either satisfaction, or dissatisfaction, (2) that there will be no general agreement for some types of demands. Correlational analysis was performed on two independent sets of data to test the hypotheses, which were both supported. These results raised questions about the status of the concept of demands itself and a recommendation is made that it be replaced by the more neutral term ‘job demands milieu’ which can be applied to other aspects of the job environment such as task‐based milieu, role‐based milieu, or physical environmental milieu.

Sex bias in hiring: Effects of job demands and applicant competence

Managers in a large corporation evaluated application materials representing one of eight hypothetical job candidates. In order to examine the effects of two types of information on sex bias, three factors were manipulated in a factorial design: (1) Applicants were either male or female engineers; (2) they appeared highly competent or moderately competent based on academic performance; (3) they were applying for an engineering job that entailed either technical engineering tasks or managerial tasks in addition to the technical tasks. Greater discrimination against women occurred in evaluations for the technical-managerial job, even with highly competent applicants. These results are explained in terms of ambiguity: Because it was not obvious that applicants would succeed on the additional managerial tasks, the evaluators resorted to stereotypes in order to make their predictions.

Relationship between Lifting Capacity and Injury in Occupations Requiring Lifting

There are several factors which affect the lifting capacity. These factors can be categorized under the following: 1. individual characteristics, 2. task variables, and 3. environmental conditions. This paper presents the methods used to determine the lifting capacity for male and female industrial workers, as well as the models developed to predict this capacity under several conditions of the task variables (height level, frequency, and box size). Since overloading and underloading in manual materials handling is undesirable, field data were collected to investigate the effects of job demands on manual materials handling injuries. As opposed to the physiological approach, no difference was found in the lifting capacity due to age. While both weight and work rate are important, work rate was a more effective and logical single measure of back injuries or stress than weight.
