Occupational Health and Labor Unions

Abstract The resurgence of labor unions in the U.S., evidenced by recent unionization successes across various industries, reflects a broader revival of organized labor's role in workplace advocacy. These developments counter a long-term decline in union membership, with global efforts also seeing modest gains. As is demonstrated in this series of contributions, labor unions remain critical in promoting occupational health and safety, mitigating workplace hazards, and addressing psychosocial risks such as stress and harassment. Historically, unions have shaped labor standards and influenced the development of safety regulations. Today, they contribute to broader societal benefits, including democratic participation, workplace well-being, and public health innovation. Despite their significant contributions, unions face challenges from globalization, technological changes, the rise of non-standard work arrangements, and political polarization. Despite the critical role unions play in occupational health and organizations more generally, organizational scientists have paid relatively little attention to unions. In response, this series of contributions highlights the need for renewed scholarly attention, particularly in industrial-organizational psychology, to support unions in safeguarding workers' rights and well-being.
