As answered by people managing JSFiddle and UnionStack.ca.
UnionStack.ca's answer:
UnionStack is built with C# and ASP.NET Core on .NET 10, using PostgreSQL and Entity Framework Core for data management. Supporting technologies include Redis, SignalR for real-time updates, OpenIddict for authentication, Azure Blob Storage for documents, and Docker for deployment.
UnionStack.ca's answer:
UnionStack addresses a practical challenge: union work spans many connected records and responsibilities. A single member may hold multiple positions, participate in a grievance, attend meetings, and exchange correspondence with several representatives. UnionStack brings that context together to make everyday administration clearer and easier to coordinate.
UnionStack.ca's answer:
UnionStack serves labour unions, including locals, regional bodies, and larger union organizations. Its primary users are union administrators, membership staff, representatives, grievance officers, and finance teams. Members use the portal to access relevant information and services
UnionStack.ca's answer:
UnionStack is a strong fit for unions seeking membership management, grievance tracking, communications, and member self-service in one platform. Its connected records help reduce fragmented information, while configurable workflows, reporting, and audit histories support consistent administration.
UnionStack.ca's answer:
UnionStack connects the people, organizations, agreements, and casework behind everyday union operations. Member records link to positions, grievances, meetings, and correspondence, helping staff understand the full context while respecting access permissions. Configurable structures and workflows let unions reflect their own organization and terminology.
