"The literature presents role conflict, role ambiguity and role overload as psychological stressors which arise when a person plays conflicting roles, receives conflicting signals of what the environment expects of him, or both. Complexity increases when a role of a plurality of roles involves more activities and when a person functions in more than a single system (environment) and hence is faced with a variety of role senders. Research into this kind of stress has not covered active labor union members, even though their position would seem to make them likely stress candidates. In this article we demonstrate that active union members do indeed face role problems. We also report findings that are generally supportive of the expected association between active union members' experience of the central component of burnout (viz. emotional exhausting) and each of the examined role problems individually and in combination (i.e. an index of overall role stress). Further, the results of a multiple regression analysis showed that emotional exhaustion was most strongly associated with intra-sender conflict and qualitative role overload."
