Organizing Campaigns and Community Partnerships

Strategic Expansion in Healthcare and Security

SEIU International Union targets growth in home care, hospital, and corporate security through facility-specific campaigns. Organizers work with local leaders to identify issues and build committee structures.

Multi-Employer Agreements

By negotiating across chains and property management groups, the union standardizes wages and benefits, reducing race-to-the-bottom dynamics. These agreements often include portability clauses for worker protections.

The union invests in community coalitions that include housing, environmental, and racial justice groups. This broad base supports legislative wins and public support during labor disputes.

Political Influence and Legislative Advocacy

Electoral Engagement and Voter Protection

SEIU International Union channels member resources into endorsments, candidate forums, and ballot access initiatives. Field programs emphasize participation among low-wage service workers.

Policy Priorities at Federal and State Levels

On Capitol Hill and in statehouses, the union backs sectoral bargaining, minimum wage increases, and workplace safety enforcement. Testimony, lobbying days, and coalition messaging amplify these positions.

Training and Professional Development

Union Leadership Development

Emerging leaders attend workshops on contract bargaining, grievance resolution, and financial stewardship. Mentoring pipelines connect seasoned stewards with new organizers.

Member Skill Building

Classroom and online modules cover workplace rights, safety protocols, and communication tactics. Credits and certifications help members advance within their careers and union roles.

Membership Benefits and Support Services

Wage Growth and Benefits Portability

Collective bargaining delivers higher base pay, predictable scheduling, and access to health coverage that follows workers across employers. Supplemental plans often include dental, vision, and retirement options.
