What Sedin does

Sedin (legal name: Sindicato dos Trabalhadores nas Unidades de Educação Infantil da Rede Direta e Autárquica do Município de São Paulo) is a private, non-profit labor union headquartered in the Aclimação neighborhood of São Paulo, Brazil. It is the statutorily recognized representative body for early childhood education professionals — including Professor de Educação Infantil (PEI), Professor de Ensino Fundamental I, and auxiliary education professionals (ATE) — working in the direct and autonomous municipal education network of São Paulo. The organization is affiliated with CTB (Central dos Trabalhadores do Brasil) and is a co-founder of COEDUC, the coordination body of municipal education unions (alongside SINESP and SINPEEM) that negotiates collective bargaining agreements with the Municipal Prefecture.

Sedin delivers a portfolio of member services organized around a digital member portal (sistema.sedinsindicato.com.br) and a regional network of elected representatives covering five São Paulo districts. Core offerings include legal representation (collective and individual lawsuits, including action filings for salary corrections such as URV conversion adjustments), a retirement projection tool, electronic pay stub access, course enrollment and professional development, position exchange management, benefits coordination (health plan, dental, pharmacy discounts, vacation colonies, parks, university partnerships), and retiree services through the Secretaria dos Aposentados. The union also runs an annual educational congress (XXI Congress themed 'Infâncias, Meio Ambiente & Sustentabilidade' in November 2025) and maintains an active presence on Instagram, YouTube, and Facebook.

The business model is membership-dues based, with no publicly disclosed revenue. The union is governed by an elected board (most recent election in 2024) and operates without external investment or ownership. Its strategic activity centers on collective bargaining through COEDUC, with a Protocol of Understanding signed with the Municipal Government on May 21, 2026 (Protocol 02/2026) covering wage appreciation, health, career development, and working conditions. Headcount is reported at 17 employees, and operations are geographically restricted to São Paulo.

• CNTE: Confederação Nacional dos Trabalhadores em Educação, the national confederation of public education workers across Brazil—functionally analogous to SEDIN but at national scale, aggregating state-level unions including those serving São Paulo.
• UGT: União Geral dos Trabalhadores, another major Brazilian labor central that federates sector-specific unions including education unions across multiple municipalities.
