The discipline on national travel

With the agreement of 20 May 2025 for the renewal of the CCNL of 4 May 2022 for employees of artisan companies and small and medium-sized industrial companies in the construction and related sectors, signed by CNA-COSTRUZIONI, ANAEPA-CONFARTIGIANATO, FIAE-CASARTIGIANI, CLAAI and the trade unions FENEAL-UIL, FILCA-CISL, FILLEA-CGIL, it was approved Annex C-2025 regarding travel. Specifically, it is provided that the national transfer regulations come into force on 1 October 2025, at the same time as the introduction of the new single declaration, and applies to construction sites started after that date.

An identical regulation regarding national travel also operates, with the same deadlines, for the entities that apply the Construction – Cooperatives and Construction – Industry CCNL, as provided for in the Minutes of 21 February 2025 (Annex 5) for the renewal of the CCNL of 3 March 2022 for employees of construction and similar companies and of Cooperatives (agreement signed by ANCE, LEGACOOP PRODUCTION AND SERVICES, AGCI-PRODUCTION AND LABOR, CONFCOOPERATIVE LABOR AND SERVICES and the trade union acronyms FENEAL-UIL, FILCA-CISL and FILLEA-CGIL).

Away construction site principle

The new regulation on travel applies to construction sites in which a worker is sent by the company on business to an area under the jurisdiction of another Cassa Edile / Edilcassa. This regulation starts from the first day of the fourth pay period of the aforementioned first worker, with specific regulation of contributions between the Cassa Edile / Edilcassa to which they belong and the Cassa Edile / Edilcassa of the place of work, as defined below.

From the same date, the same discipline also applies to any other workers sent on secondment by the company after the first, to the same construction site, provided that the relative secondment of the individual worker lasts for at least an entire monthly pay period.

The Cassa Edile to which you belong remains the sole point of contact for the company

The company, for all workers on secondment and for the entire duration of the same, continues to fulfill the obligations established by the national and territorial bargaining at the Cassa Edile / Edilcassa to which they belong, which is responsible for the obligations towards the Cassa Edile / Edilcassa of the place of work. The services in favor of the company are provided by the Cassa Edile / Edilcassa to which they belong.

The worker remains registered with the construction fund to which he belongs

Regardless of the duration of the trip, the worker remains registered with the Cassa Edile / Edilcassa to which he belongs which provides benefits to the employee in relation to the recognition of hours.

Standardized requirements for companies and building funds

According to the provisions of Annexes C-2025 and 5, through the specific IT application, with a single requirement, the company communicates in advance to the Cassa Edile / Edilcassa to which it belongs and to that of the place of work of the opening of the construction site/start of the works.

Subsequently, the monthly reports are made by the company for the benefit of the Cassa Edile / Edilcassa to which it belongs and, again through the application, the data relating to the aforementioned construction site are also automatically displayed by the Cassa Edile / Edilcassa of the place of work.

Single Construction Report (DUE)

In the Minutes of 21 February 2025 (Annex 4) and 20 May 2025 (Annex F-2025) the signatories agreed that the new form of Single Construction Report (DUE) presents, in order to effectively make procedures and behaviors of all Building Funds / Edilcasse, a series of mandatory and blocking elements including, in letter i), the regulation on travel, according to the new formulation of article 24 of the CCNL Construction – crafts, of article 21 of the CCNL Construction – industry and of article 61 of the CCNL Construction – cooperatives.

From the signing of the contractual renewal, a joint commission of the social partners will be established in charge of defining the single complaint form. The Single Report system, following the findings of the Commission, comes into force from 1 October 2025.

Conclusion of the Commission’s work

With an agreement dated 8 October 2025, implementing the provisions of Annex F of the Artisans CCNL and Annex 4 of the ANCE/Cooperative CCNL, at the end of the work of the Joint Commission (which made use of the support of the CNCE) ANCE, ANAEPA-CONFARTIGIANATO, CNA-COSTRUZIONI, FIAE-CASARTIGIANI, CLAAI-EDILIZIA, LEGACOOP PRODUCZIONE Eservizi, AGCI-PRODAZIONE E LAVORO, CONFCOOPERATIVE LAVORO Eservizi and the trade union acronyms FENEAL-UIL, FILCA-CISL and FILLEA-CGIL, have approved a technical document (attached to the agreement) which constitutes a uniform model to which, once the IT system relating to the DUE itself and the national trip has been implemented at a national level, all Casse Edili / Edilcasse will have to adapt.

Reporting obligation for construction sites

With reference to the DUE model, the signatory Parties of the agreement of 8 October 2025 agree that “the obligation to report per construction site remains unchanged” with the sole exception of the company’s right to indicate a “general construction site in the presence of all the following conditions”:

  • Private work not subject to adequacy verification;
  • Salary mass reported in the aforementioned generic construction site not exceeding 7 thousand euros/month;
  • Presence of a report from at least one other specifically identified construction site (with at least one worker reported).

The definition of generic construction site does not apply for the works referred to in Legislative Decree number 189/2016.
