Syndicat National des Employeurs Spécifiques d'Insertion (SyNESI)

What Syndicat National des Employeurs Spécifiques d'Insertion (SyNESI) does

SyNESI (Syndicat National des Employeurs Spécifiques d'Insertion) is the sole representative employers' trade union within the French ACI (Ateliers et Chantiers d'Insertion) branch of the Insertion par l'Activité Économique (IAE) sector. Founded in 2006 by four employer networks — Chantier École, Jardins de Cocagne, Coorace, and Tissons la Solidarité — and joined by Emmaüs France in 2024, SyNESI negotiates and interprets the national collective agreement (CCN 3016), represents employers in paritarian commissions, and defends the sector's public funding model before French government authorities. Its members are ACI structures — non-profit enterprises that provide work-based reintegration programs for individuals facing social and professional exclusion — and the organization surpassed a symbolic 300-member threshold at year-end 2024.

SyNESI's core deliverable is not a software product but a service bundle: legal advisory on labor law and CCN 3016, collective bargaining representation, regulatory monitoring, monthly webinars co-organized with Cornillier Avocats, a member-only document database and FAQ, regional employer days (JEA), and annual general assemblies. Its technology footprint consists of a website (synesi.org) with a member portal, an automated online fee calculator, newsletter infrastructure (SYNINFOS), and webinar/event hosting. The organization does not offer public APIs, mobile applications, or AI-driven features; its technology layer is administrative and communication-oriented rather than product-oriented.

SyNESI is registered as an Association Syndicale Libre (ASL) under French law and is financed entirely through annual membership dues paid by ACI employer structures. Membership enrollment runs annually from March to June through a fully digital process, with fees calculated via an online calculator (specific amounts are not publicly disclosed). The organization operates exclusively in France from a Paris headquarters (36 rue de Laborde, 75008 Paris), with a permanent team of approximately 10 staff (a core permanent team of Marion, Maxime, Fabien, and Adrien plus elected officials, negotiators, and mandated representatives participating in governance). Strategic partnerships with Uniformation (OPCO for training), Harmonie Mutuelle/VyV and Mutex/OCIRP (designated branche-level health and prévoyance insurers from January 2026), UDES (social economy employer union), and its four founding networks anchor SyNESI's position within the broader French social economy ecosystem.

Others

• Uniformation: OPCO (Opérateur de Compétences) financing vocational training across the social economy, including the ACI branche. A strategic ecosystem partner of SyNESI for branche-level training axes, rather than a competing employer union.
• Harmonie Mutuelle (Groupe VyV): Recommended branche-level health insurer for the ACI branch following SyNESI's 2025 competitive tender. Not a peer but a direct counterparty in the paritarian social protection framework SyNESI administers.

Direct peers

• Chantier École: Founding network of SyNESI and the largest national federation of ACI structures. Chantier École operates regional federations and partners with SyNESI on JEA events, making it the closest structural counterpart to SyNESI within the insertion ecosystem.
• Coorace: One of the four founding networks of SyNESI in 2006, Coorace is a national federation of insertion enterprises (EI and ACI). It shares SyNESI's insertion-sector focus and member-network structure, though operating as a network rather than a branche-level union.
• UDES (Union des Employeurs de l'Économie Sociale): The French employers' union of the broader social economy (ESS) in which SyNESI itself is a member. Operates the same model — collective bargaining, paritarian representation, sectoral advocacy — but at a wider ESS scope rather than ACI-specific.
• Fédération des Entreprises d'Insertion (FEI): French employers' federation representing Entreprises d'Insertion (EI), the sister structure to ACI within the IAE framework. Mirrors SyNESI's role but for EI; together the two federations cover the bulk of IAE employer representation in France.

Broad incumbents

• Nexem: Major French employers' federation in the social and medico-social sector, representing a much broader set of structures than SyNESI. Comparable bargaining/advocacy model but at a larger, multi-sector scale (disability, social protection, etc.).
• Conseil National des Employeurs Associatifs (CNEA): French employers' union representing associative employers across social economy sectors; comparable to SyNESI's bargaining/advocacy model but at broader associative scope rather than ACI-specific.

Emerging players

• Emmaüs France: Recently joined SyNESI as its fourth affiliated network in 2024. Emmaüs France is both an advocacy organization and an operator of ACI structures under the Emmaüs umbrella, overlapping with SyNESI's membership universe and increasingly acting as a partner-federation.
• Réseau Cocagne: Federation of Jardins de Cocagne (organic market-gardening insertion structures), one of SyNESI's founding networks. Shares the IAE insertion-employer focus and member-network model but concentrated on the market-gardening sub-segment.
