Built for labor unions.
Trusted by locals across North America.

eMembership serves labor unions across a wide range of industries, sizes, and structures. Current clients include locals affiliated with SEIU, IATSE, IBEW, ILWU, IUOE, CUPE, and Workers United, as well as independent non-affiliated unions in law enforcement, government, and the performing arts. Two international unions are also among eMembership's clients.

eMembership is consistently recognized as one of the most comprehensive union management platforms available. With 18 configurable modules covering everything from member management and grievances to organizing, dispatch, contracts, and member payments, it offers broader feature coverage than most alternatives. Unlike some platforms that started as general association or nonprofit tools, eMembership was built from the ground up for labor unions. It also charges a single subscription with no per-user or per-seat fees, which is a meaningful difference for unions with growing staff or membership.

Yes. eMembership scales to organizations of any size. Small independent locals with a few hundred members use the platform alongside large organizations with tens of thousands of members across multiple locals or chapters. Two international unions are among eMembership's current clients. The modular architecture means smaller unions can start with the modules they need and add more as they grow.

Yes. eMembership supports both traditional employment models and hiring-hall dispatch workflows. The platform is configurable to handle dispatch rules, work history tracking, eligibility management, and the member management requirements that dispatch-based locals depend on. This is one of the areas where purpose-built union software makes a significant difference compared to generic platforms.

Yes. eMembership supports multiple dues collection methods including employer checkoff and direct member payments, as well as complex rate structures by employer, region, contract, and classification. The platform is configured to match your local's specific dues structure rather than requiring you to simplify your rules to fit the software.

Yes. eMembership is used by unions operating in both labor-friendly and right-to-work states. The platform supports the membership tracking, dues management, and compliance workflows that unions in right-to-work environments require, including tracking authorization status and member opt-in records.

Yes. eMembership works equally well for independent, non-affiliated labor unions. Winmill works with a number of independent organizations across industries including law enforcement, government, and the performing arts. Not having an international affiliation does not limit what you can do with the platform.
