UnionStack is a web-based management platform for labour unions. It connects membership records, organizations, casework, communications, and member services in one system, helping staff keep information organized and coordinate their daily work.

Unions can configure the platform around their own structure, including locals, regions, employers, worksites, and committees. Connected records bring together members’ positions, organizational relationships, cases, meetings, and correspondence.

Key features include:

  • Membership management: Maintain member profiles, contact information, positions, leadership roles, documents, and custom fields, with tools for imports and duplicate review.
  • Grievance and case management: Track intake, assignments, workflows, deadlines, evidence, correspondence, and outcomes.
  • Collective agreements: Manage agreement terms and articles, preserve historical versions, and compare successor agreements.
  • Communications: Connect email accounts, manage conversations, send individual or bulk messages, and link correspondence to casework.
  • Meetings and events: Organize agendas, minutes, action items, registrations, attendance, and certificates.
  • Member self-service and websites: Provide branded websites and a member portal with access to relevant profiles, cases, meetings, events, and financial information.
  • Finance administration: Process expense claims and employer dues files, resolve exceptions, and reconcile remittances.
  • Reporting and access controls: Monitor membership trends and case activity with role-based permissions and audit histories.

UnionStack is designed for union administrators, representatives, caseworkers, and members who need shared information across everyday union operations.
