Sindicato de Obreros de Maestranza

What Sindicato de Obreros de Maestranza does

Sindicato de Obreros de Maestranza (SOM, also known as SOMRA) is an Argentine labor union founded in 1943 that represents workers employed in maintenance and cleaning activities (obreros de maestranza) under the CCT 74/99 collective bargaining agreement negotiated with ADEL, the employer counterpart association. The union operates as a non-profit entity with an elected Consejo Directivo chaired by Secretary General Oscar Guillermo Rojas, and operates 19+ regional delegations spanning from Buenos Aires metropolitan area to Ushuaia in Tierra del Fuego. Its revenue mechanics are structurally mandated: workers contribute 2.5% of gross salary as union dues and 3% as health insurance contributions to the affiliated Obra Social del Personal de Maestranza (OSPM), both deducted at source via employer payroll.

The core product is the OSPM health insurance plan, which serves over 100,000 beneficiaries and has been continuously ranked among the top 10 Argentine health insurance funds (obras sociales) by the Superintendencia de Servicios de Salud since 2005. OSPM is differentiated by offering coverage without copayments, without waiting periods (sin carencias), and without exclusions for pre-existing conditions — a structurally generous benefit design relative to peer obras sociales. The underlying technology stack includes a proprietary digital prescription system (Mis Rx Digital) compliant with Ministry of Health Resolution 5744/2024, a provider portal at prestadores.ospm.org.ar, a patient portal for prescription history, and an online training platform (SOM Side Pro) for continuing education. Payment processing is integrated across Banco Nación, Pago Fácil, and Mercado Pago.

Beyond collective bargaining and healthcare, SOM delivers a full member-services ecosystem: free in-person and online training courses, legal advisory services, recreational and tourism facilities (Centro Deportivo Marcelo Ibarrola, vacation colonies, summer tourism packages), annual school kit distribution, children's day events, and on-site social security administration via the "ANSES va a tu Trabajo" program. The go-to-market motion combines employer-driven enrollment (companies must register with SOM and remit payroll deductions) with a community-led delegate network embedded at member workplaces across airports, shopping centers, factories, and hospitals. Distribution relies on physical delegations, contracted healthcare providers, affiliated pharmacies, and an expanding digital self-serve surface.

Scale indicators3 records

Recent moves7 records

Expansion highlights5 records

Broad incumbents

• OSDE: Largest Argentine obra social/prepaid health plan affiliated with the commerce sector (CEC/FAECYS). Highly relevant benchmark for OSPM because of the dual obra social/prepaga model, broad provider network, and national brand — although OSDE serves a higher-income member base and operates at substantially larger scale.
• Galeno Argentina: Major Argentine prepaid health plan with proprietary sanatoriums and a national provider network. Comparable to OSPM as an alternative coverage option for Argentine workers, particularly upper-income segments that prepaga competitors typically target versus obra social captives.
• Swiss Medical Group: One of Argentina's largest private prepaid health plan operators with own clinics and provider networks. A relevant indirect competitor/comparable for OSPM on the health-plan delivery side — flagship benchmark for what prepagas offer versus obra social coverage.

Direct peers

• SUTERH (Sindicato Único de los Trabajadores de los Edificios de Renta y Horizontal): Argentine labor union representing building maintenance and doorman staff with an affiliated obra social and healthcare network. Closely analogous to SOM in mandate scope (building-related services workers), structure (union + obra social under a CCT), and revenue model (mandatory payroll contributions).
• FAECYS / CEC (Federación Argentina de Empleados de Comercio y Servicios): Largest Argentine commercial/retail workers union, with affiliated obra social covering over a million members via CCT-based employer contributions. Closely comparable to SOM structurally (worker union + obra social + mandatory payroll contributions + ADEL-style employer counterpart), though serving the commerce vertical rather than maestranza.
• UPCN (Unión del Personal Civil de la Nación): One of Argentina's largest state-employee unions, with an affiliated obra social covering hundreds of thousands of public-sector workers. Comparable to SOM as a major Argentine union operating a health plan for members via payroll contributions, though UPCN serves government rather than private-sector service workers.
• Sancor Salud: Mutual/cooperative health plan covering members across much of Argentina, anchored historically in the dairy/cooperatives sector. Comparable to OSPM as a multi-province health plan with regional delegations, contrasting on cooperative rather than union-trust ownership.
• UTHGRA (Unión de Trabajadores del Turismo, Hoteleros y Gastronómicos): National Argentine labor union for hospitality, gastronomy, and tourism workers, operating its own obra social (OSUTHGRA). Comparable to SOM as another service-sector union with affiliated health plan serving a low-wage member base via mandatory payroll deductions and a CBA framework.
