Leadership and substitutes for leadership among professional and nonprofessional workers.
In this article, the authors discuss their research on similarities and differences between professionals and nonprofessionals in their responses to managerial leadership behaviors and substitutes for leadership. Their study sample comprised workers at many organizational levels in several hospital and contract research organizations in the Southwest, and they used a multidimensional measure of professionalism to create subsamples of professionals and nonprofessionals. The authors used questionnaire data to test hypotheses regarding instrumental and supportive leadership behaviors and their substitutes. They found that role clarification and support from leaders were important predictors of worker's job satisfaction and organizational commitment for both subsamples, and that formal rules and procedures were an important supplement for instrumental leadership behaviors. Professionals differed from nonprofessionals in that intrinsically satisfying work tasks and importance place on organizational rewards were strong substitutes for leaders' support. The authors conclude that worker professionalism is an important moderator variable for research on leadership and substitutes for leadership.
