Italian “Fiscal Decree” extends again the prohibition of dismissal until 31 December 2021 (Article 11, Legislative Decree 146/2021).

Employers who access ordinary and ‘cassa in deroga’ check (Maximum thirteen weeks; No additional contribution);

In any case, while the block is in effect, it is always possible to terminate the employment relationship in the following cases:

corporate collective agreement;
expansion contract;
reinstatement for change of contract;
bankruptcy;
definitive termination of the company’s business (which does not involve the transfer of a company or one of its branches);
just-cause dismissal;
dismissal for disciplinary reasons;
dismissal for exceeding the grant period of illness;
dismissal for failure to pass the probationary period;
dismissal for reaching age for the use of the old-age pension;
dismissal for unfitness for duties;
dismissal of the domestic worker;
dismissal of the manager (even if a recent jurisprudential orientation is contrary);
the termination of the apprenticeship at its expiration date;
consensual employment terminations and resignations for just cause.
