The Court of Cassation states the following principles:
1) The mere termination of the job performances is not sufficient to prove the dismissal but it is necessary that, even if orally communicated to the employee, the latter has to prove it.
2) If the fact challenged to the employee falls within the practice tolerated by the employer, the disciplinary dismissal must be considered unlawful due to lack of proportionality.
3) The judge can base his conviction on the existence of a just cause of dismissal also on evidences which derive from investigations carried out in criminal procedures.
4) An employee can ask the employer to have access to all his personal data, including those not having an objective nature, contained in documents that lead to business decisions.
5) In lack of social security provision according to Article 10 of Insurance Law on compulsory insurance in the workplace, there is no insurance coverage, therefore civil liability for accidents at work falls on employer.

The Italian Court of Cassation, with judgment no. 3133 dated 1 February 2019, confirmed the dismissal for just cause of an employee as a consequence of a check made by the employer on internet chronology of the computer, which would have revealed an excessive personal use of internet during working hours.
