Questione giuridica chiave
Whether the cantonal court violated the duty to give reasons by not explaining why X.________ SA, not Y.________ SA, was the employer.
Decisione estratta
Yes. The judgment did not disclose the factual basis for the passive standing finding, so the appellant could not effectively challenge it.
Motivazione estratta
The reasoning must at least briefly show the decisive facts and legal path. Here, the court merely asserted that the contract was with X.________ SA, without identifying the relevant facts supporting that conclusion.
