SEIU Local 6, known as SEIU6 Property Services NW, represents more than 9,000 janitors, security officers, airport passenger service workers, stadium and event workers, and allied industry workers across Washington. Local 6 is one of the locals chartered by the Service Employees International Union, one of the largest labor unions in North America.

A workforce that size, spread across property services, security, transportation, and event work, places real demands on a union's data systems. Member rosters change constantly, employer billing arrangements vary, and grievance cases need to stay linked to the members they concern. Local 6 needed software that could carry that complexity without breaking under it.

To unify its operations, Local 6 turned to eMembership for an integrated platform that brings union member data, employer billing, grievance management, and member communications together in one system.

A basic membership system, and grievances tracked separately

Before adopting eMembership, Local 6 ran on a basic membership solution that lacked the depth needed to manage a 9,000+ member base, paired with a separate grievance system that operated independently. Keeping data aligned between the two consumed hours of staff time every week.

• Limited depth in the membership system. The existing solution could not fully represent the breadth of Local 6's membership across property services, security, and transportation.
• Grievances disconnected from member data. Case information lived in a separate system from the member it concerned.
• Manual data synchronization. Aligning information between the two systems was labor-intensive and prone to errors.
• Slow data migration and reporting. Pulling consolidated views for leadership required exporting and reconciling data by hand.

Local 6 needed a single platform that could carry the full union member data picture, manage dues and employer billing at scale, and bring grievances back into the member record where they belong.

One platform for member data and employer billing

Local 6 selected eMembership in part because of Winmill's experience serving 17 other SEIU locals. The implementation centered on three modules that addressed the largest pain points: a robust employer billing engine, a centralized employer management view, and a flexible data import pipeline for the initial migration.

Employer Payments and Billing

Dues collection across many employers became one workflow rather than several. The module supports the billing variations that exist across Local 6's employer base, including bargaining-unit-specific rules, and provides transparency on what is owed and what has been paid.

Employer Management

Employer records, contacts, contract terms, and member rosters live in one place. Staff see employer interactions and union activity from the same view, which makes employer-side communication and grievance handling faster.

Data Import

The migration from the legacy systems was handled by the data import module, which supports varied formats and sources. Member, dues, and historical case data moved into eMembership with minimal downtime.

A single platform for the whole local

Beyond unifying member data, Local 6 uses a range of integrated tools within eMembership:

• Union grievances linked back to member records and employer context
• Bulk email and SMS union communications targeted by classification, status, or employer
• Custom union administration reports with Excel export for leadership and bargaining prep
• Union electronic signatures for membership applications and authorizations
• Union meetings and event management with attendance tracking
• A union member portal for member self-service

One unified view across members, employers, and cases

With eMembership, Local 6 operates from a single source of truth across member data, employer billing, and grievance history.

• Member data and grievances unified. No more manual synchronization between separate systems.
• Dues collection automated at scale. Employer billing runs as one workflow across many employers and bargaining units.
• Employer-side context in one place. Employer records, contracts, and member rosters live alongside member data.
• Faster decisions. Real-time access to consolidated data lets leadership make informed decisions without waiting for reconciled exports.
• Implementation that respected the data. The data import module moved years of records into eMembership with minimal disruption.
