Practical Implications for Territorial Controls

One of the most important innovations envisaged by the project concerns the direct access to the data of the information system on admission to circulation (SIAC) managed by the Federal Office of Roads. Currently, supervisory authorities are often in difficulty when they have to operate outside the company premises, as in the case of inspections on construction sites. With the proposed new legal basis, inspectors will be able to verify the identity of employers and workers directly through on-site company vehicles. This step will greatly simplify on-site assessment procedures, reducing downtime and increasing the operational capacity of cantonal control teams.

Integration with corporate transparency

The project also aims to fill a regulatory gap that has emerged in relation to the Law on the Transparency of Legal Entities. The proposal provides that the enforcement bodies, active in the prevention and fight against insurance fraud and undeclared work, can report to the register for transparency any discrepancies detected during their activities.

What to do in case of checks

It is essential to always keep employee documentation and proof of affiliation to the AVS/AI/IPG compensation funds available. With the introduction of access to SIAC data, consistency between declared means of transport and business activity will become an immediate point of verification for inspectors. Therefore, each company must ensure that the vehicles used are correctly registered and that the information in the trade register is constantly updated. In case of doubts about the correct interpretation of the regulations in force or the management of employment contracts, it is always advisable to consult the directives of the SECO or contact the competent cantonal offices for the fight against undeclared work in your canton of residence or place of work.
