Sindser

What Sindser does

Sindser (full legal name: Sindicato dos Servidores e Empregados da Administração Direta, Fundacional, das Autarquias, Empresas Públicas e Sociedades de Economia Mista do Distrito Federal), operating under the trade name SINDSER-DF, is a Brazilian non-profit labor union headquartered at Setor de Diversões Sul (Conic), Ed. Venâncio V, Loja 20, Brasília, Federal District. The organization represents public sector workers employed by the direct administration of the Government of the Distrito Federal (GDF), as well as workers from autonomous agencies (autarquias), foundations, public companies, and mixed-economy enterprises — including NOVACAP, TERRACAP, DER-DF, Codeplan/IPEDF, Caesb, SEAGRI, and ARCEF.

Sindser operates a community-led go-to-market focused on workplace delegate networks, physical member assemblies, and multi-channel digital communications (Facebook, X, Instagram, WhatsApp, Telegram, LinkedIn, Pinterest, and the sindser.org.br website). Its core services include collective bargaining representation, legal defense, mobilization against privatization and benefit cuts, and lobbying within legislative bodies such as the Câmara Legislativa do Distrito Federal (CLDF). The union has secured judicial standing as amicus curiae before the TJDFT and has obtained court victories enforcing retroactive salary adjustments.

Revenue is generated exclusively through recurring membership dues paid by represented workers; financial details are not publicly disclosed. Sindser maintains a strategic partnership with ARCEF for joint representation of SEAGRI workers and ongoing legislative engagement with CLDF. The union is led by President André Luiz and is governed independently as a member-controlled non-profit, with no parent company, subsidiaries, venture capital, or equity financing structures.

Partnerships

Three partnerships are on record, tiered core.

• CLDF (Câmara Legislativa do Distrito Federal)coreOthers · 17 June 2026Sindser maintains ongoing relations with the Legislative Chamber of the Federal District (CLDF). The union's president André Luiz had a productive meeting with the CLDF president on June 17, 2026. Sindser also organized assemblies and occupied CLDF galleries to lobby against bills threatening public assets and workers' rights, successfully blocking the approval of a GDF project on February 24, 2026.
• TJDFT (Tribunal de Justiça do Distrito Federal e Territórios)coreStrategic or Co-development Partner · 31 March 2026Sindser was accepted as amicus curiae by the TJDFT in a Popular Action lawsuit against ex-Governor Ibaneis Rocha and BRB to defend the public patrimony of the Federal District. The union will assist the court with information about public real estate properties included in the law being challenged, including aspects of regularization, economic and social relevance, and market value.
• ARCEF (Associação dos Servidores da Agricultura)coreStrategic or Co-development Partner · 5 February 2026Sindser maintains a strategic partnership with ARCEF (Association of Agriculture Servers) to jointly mobilize and represent workers from SEAGRI (Secretariat of Agriculture).

In a February 2026 meeting, both organizations prioritized mobilization as the main instrument of struggle and planned a general assembly for March 2026.

Recent moves5 records

Expansion highlights3 records

Broad incumbents

• Força Sindical: Major Brazilian labor central federation. Comparable as a labor organization engaging in collective bargaining and political advocacy for affiliated workers, but distinguished by national scope and federation structure rather than local direct membership like Sindser.
• CTB (Central dos Trabalhadores e Trabalhadoras do Brasil): Brazilian labor central representing worker interests across multiple sectors. Analogous as a labor organization using collective bargaining and worker mobilization, but operating as a national federation rather than a single DF-level union with direct member-to-union relationships.
• CUT (Central Única dos Trabalhadores): Brazil's largest national labor central/federation. Comparable as a labor union umbrella organization representing worker interests through collective bargaining, strikes, and legislative advocacy—though operating as a federation of affiliated unions rather than directly enrolling individual workers like Sindser does.
• Condsef/Fenasps: National-level confederation representing federal public servants across Brazil. Comparable as a labor union for public-sector workers using the same collective bargaining and mobilization tactics, but operating at federal scope rather than DF-only scope and serving a broader cross-vertical public workforce.

Direct peers

• Sindsep-DF: Brasília-based public sector workers union. Directly comparable as a DF municipal/state public sector union organizing similar categories of GDF workers for collective bargaining, using the same assembly-based GTM and WhatsApp-led recruitment approach as Sindser.
• Sindjus-DF: Federal District union representing judicial and public ministry workers. Similar DF-based labor union competing for adjacent public-sector constituencies (Poder Judiciário/MPU vs. Sindser's GDF administratives, autarquias and state-owned enterprises), using the same collective bargaining and legal representation playbook.
• Sinpro-DF: Union representing public- and private-sector teachers in the Federal District. Same geographic scope (DF), same public-sector employee membership base, and same collective bargaining and labor-rights advocacy model, though focused specifically on the education vertical.
• Sindsprev-DF: DF union representing public health sector workers. Peer because it operates in the same geography (Brasília), same legislative engagement model (CLDF lobbying), and represents GDF-affiliated public workers—just in the healthcare vertical rather than the broader administrative/utility verticals Sindser covers.
