From the abstract:
Debates over revitalizing the U.S. labor movement often overlook when workers are first unionized. This article analyzes the frequency and nature of workers’ first unionized jobs by tracking a cohort of individuals from age 15/16 to 40/41. Though workers are most likely to be unionized when they are in their forties, this article shows that surprising numbers of individuals first encounter unionization in their jobs at a much younger age. These results highlight the importance of experiential union membership models as well as life-cycle union representation strategies that recognize the young age at which many workers are first unionized.
