Work Group Demography, Social Integration, and Turnover

The authors gratefully acknowledge the assistance of Blake Frank for his help in obtaining the turnover data for this study and the University of California Institute of Industrial Relations for research support. Using 20 actual work units with 79 respondents, this study explores the relationships among group demography, social integration of the group, and individual turnover. Results suggest that heterogeneity in group tenure is associated with lower levels of group social integration which, in turn, is negatively associated with individual turnover. Models of these effects using individual-level integration measures are not significant. Further, the results suggest that it is the more distant group members who are more likely to leave. Both individual-level and group-level age demography directly affect turnover and are not moderated by social integration. The findings suggest a process by which group demography affects outcomes and support the usefulness of organizational demography for understanding group and individual functioning.'
