Cassazione Civile - Sentenza n. 12276/2026

Key Facts

Issues

• The court needed to determine whether the Collective Labor Agreement for Environmental Services (CCNL Federambiente) applies to workers employed by a social cooperative (COOP 134 Coop. Sociale) in public procurement contracts for waste collection services. The core question is whether the tender documents specifically reference CCNL Federambiente or merely the general 'environmental services sector,' and whether social cooperatives can apply their own collective labor agreement (CCNL Cooperative Sociali) instead.
• The court examined whether the tender documents (bandi di gara), special specifications (capitolati speciali), letters of invitation, and clarification letters from Hera S.p.A. establish a specific reference to CCNL Federambiente or allow for alternative collective labor agreements. The key issue is whether subsequent letters of invitation can modify or derogate from the original tender document provisions that explicitly reference CCNL Federambiente as the minimum treatment standard.
• The court addressed whether the requirement to apply CCNL Federambiente minimums to social cooperative workers in public procurement contracts violates constitutional principles. Specifically, the court examined whether this requirement infringes upon freedom of contract (Article 39 Constitution) and freedom of economic initiative (Article 41 Constitution), or if it is compatible with the legal framework governing public procurement and collective labor agreements.
• The court analyzed Article 8-bis of CCNL Federambiente, which provides for derogations from the minimum treatment clause for disadvantaged workers within specific percentage limits. The issue is whether the worker in question (Sanchini) qualifies as a disadvantaged worker under this provision, and whether the tender documents' conflicting statements about derogations can override the clear reference to CCNL Federambiente in the main procurement documents.

Holdings

• La Corte di Cassazione rigetta il ricorso proposto da Coop 134 Coop. Sociale contro la sentenza della Corte d'Appello di Bologna n. 123/2024, confermando l'applicazione del CCNL Federambiente ai lavoratori del servizio di raccolta rifiuti nell'ambito dell'appalto pubblico, e disponendo che la Cooperativa deve osservare il trattamento economico e normativo del CCNL dei Servizi Ambientali. La Corte ha confermato che i bandi di gara e i capitolati di appalto indicano espressamente il CCNL Federambiente come parametro del trattamento minimo garantito ai lavoratori, senza deroghe per le cooperative sociali.
• La Corte condanna la ricorrente Coop 134 Coop. Sociale alla rifusione delle spese del giudizio di legittimità nei confronti di Agostino Greco, con liquidazione di euro 5.500,00 per compensi professionali, euro 200,00 per esborsi, euro 2.500,00 per ciascuno dei procedimenti ex art. 373 c.p.c., oltre spese forfettarie nella misura del 15% e accessori come per legge. La regolazione delle spese segue il criterio di soccombenza.

Remedies

• Coop 134 Coop. Sociale is ordered to pay litigation expenses in favor of Agostino Greco totaling €5,500.00 for professional fees, €200.00 for expenses, €2,500.00 for each of two procedures, plus 15% flat-rate expenses and accessories as per law.
• The Court rejects the appeal filed by Coop 134 Coop. Sociale.
• Coop 134 Coop. Sociale is ordered to pay an additional amount as unified contribution equal to the original appeal amount, pursuant to article 13, paragraph 1 quater of D.P.R. n. 115/2002.

Legal Principles

• The court emphasized that public procurement procedures must be conducted in accordance with principles of good faith and social responsibility. The application of sector collective labor contracts to public procurement serves to prevent unfair competition, ensure equal treatment of workers performing the same tasks in the same area, and protect minimum standards of economic and occupational treatment established by the law.
• The court held that public procurement tender documents and bidding specifications create binding contractual obligations requiring the application of the collective labor contract of the sector (CCNL Federambiente/Servizi Ambientali). The principle of pacta sunt servanda requires that the agreed contractual terms in the tender documents must be honored, and that letters of invitation or clarification cannot modify or derogate from the main tender documents which constitute the lex specialis of the selection procedure.
• The court applied literal interpretation of the tender documents, bidding specifications, letters of invitation, and clarification letters to determine that they univocally identify the Federambiente CCNL as the specific collective labor contract parameter for economic and normative treatment of workers employed in the public contract. The interpretation is based on the literal text of the documents rather than general sector references.

Key Disputed Contract Clauses

• The tender documents (bandi di gara), special specifications (capitolati speciali), letters of invitation, and clarification letters from Hera S.p.A. consistently reference CCNL Federambiente as the specific parameter for economic and normative treatment, creating binding contractual obligations for the awardee.
• Article 8, Part A, paragraph 1, letter d) of the CCNL Servizi Ambientali (Federambiente) requires contracting companies to ensure workers receive economic and normative treatment prescribed by the sector's collective labor agreement, including application of Article 6 in case of management transfer.
• Article 30, paragraph 4 of D.Lgs. 50/2016 provides that personnel employed in public procurement works must be subject to the collective labor contract in force for the sector and area, stipulated by the most representative employer and worker associations at the national level.
• Article 8-bis (Part B) of CCNL Servizi Ambientali concerns social integration for disabled and marginalized workers, allowing derogations from the minimum treatment clause for disadvantaged workers within specific percentage limits (5% minimum, up to 15% with RSU/RSO agreement).
• Article 118, paragraph 6 of D.Lgs. 163/2006 (Public Contracts Code) requires the contractor to observe the economic and normative treatment established by collective labor contracts in force for the sector and area where services are performed, and holds the contractor jointly liable for subcontractor compliance.
