The effects of unions on blue collar role stresses and somatic strain
基于1977年美国就业质量调查数据，研究工会会员身份对蓝领工人角色压力（角色模糊、超载、角色间冲突）和躯体抱怨的影响，发现工会会员报告更高的角色模糊和角色间冲突，但工会感知绩效高时压力更低。
Abstract This study explored the effects of union membership versus nonmembership on role based stress (i.e. ambiguity, overload, and interrole conflict), somatic complaints, and on the relationship between role stress and somatic complaints. The data analyzed came from the 1977 Quality of Employment Survey (Quinn and Staines, 1979). Only those respondents ( N = 251) who held full‐time nonsupervisory jobs in manufacturing were included in our sample. On the average, relative to nonmembers, union members reported higher levels of ambiguity and interrole conflict, but similar levels of overload and of somatic complaints. Union membership moderated the relationship between overload and somatic complaints. For union members, higher perceived performance of the union was associated with lower perceived stress and strain. We discuss the implications of those findings for further research on the impact of unions on stress, strain, and their interrelationship.
