Discriminating characteristics of union members’ attitudes toward drug testing in the workplace

In this study of the acceptance by union members of drug testing in the workplace, 919 union members from 13 major unions were asked what drug-testing policy, if any, they preferred. Respondents evaluated particular aspects of a hypothetical drug-testing program. The results show that a large majority of union members agree with a limited drug-testing policy. Five theoretical models of union member attitudes were extrapolated to the drug-testing context and were examined by using discriminant function analysis. No support was found for the individual demographics theory, but empirical support was found for some elements of instrumental union, bargaining outcomes, general normative attitude, and workplace conditions theory. The discriminant function was 80.56 percent successful in classifying union members who accept drug testing.
