SEIU Local 1

What SEIU Local 1 does

SEIU Local 1 is a labor union chartered under the Service Employees International Union federation, founded in 1921 and headquartered in Chicago. It represents approximately 45,000-50,000 workers across five to six Midwestern states (Illinois, Indiana, Michigan, Missouri, Ohio, Wisconsin), with an organizing footprint spanning roughly 10 cities and a staff of about 153 employees. Its core membership segments include commercial janitors, security officers, higher education faculty and staff, food service workers, and—through recent organizing—rideshare drivers and brewery janitorial workers.

The union's operational model is built around collective bargaining, worksite representation, and political advocacy. It negotiates and administers multi-employer and single-employer collective bargaining agreements (e.g., the Chicagoland Commercial Janitors contracts covering approximately 8,000 members), pursues new organizing campaigns (Anheuser-Busch brewery, Kansas City Royals stadium workers), and engages in regulatory and electoral activity (Michigan Right-to-Work repeal, Chicago mayoral endorsements, Climate Jobs Illinois Coalition membership). Revenue is generated almost entirely through recurring member dues, with supplementary income from per-capita assessments and investment returns typical for nonprofit labor organizations.

Service delivery to members consists of grievance handling, contract enforcement, wage and benefits negotiation, training, and political mobilization. The union has no proprietary technology product; its core "platform" is its bargaining infrastructure—collective bargaining agreements, certified representation rights, and worksite stewards—which together convert member dues into negotiated wage scales, benefits, and workplace protections.
