Through in-depth interviews with nonprofit workers and full-time union organizers in the nonprofit sector, this qualitative study examines the causes, outcomes, and workers’ perceptions of the recent nonprofit worker unionization movement. We found that chronic low pay, substandard working conditions, and a concern for compromised services to clients were the impetus for workers’ labor organizing. Interviews revealed that existing unionization efforts yielded significant wins for workers. This shows that nonprofit organizations could figure out resources to reprioritize labor costs even though they face constraints by funders. Unionization also benefited nonprofit management, including favorable work policies applying to managers and reduced staff turnover. Previous literature suggests that the highly gendered and value-based labor dynamic in nonprofits is a barrier to labor organizing. We found that workers are reevaluating this sacrificing, “labor-of-love” logic and aligning workers’ rights with clients’ rights. This has transformed a barrier to a powerful facilitator for labor organizing.
