The Author analyses the juridical problems created by the norm that provides for collective agreements to set up solidarity funds for redundancies in the sectors not covered by the ordinary social protection. The law provides, in fact, for a particular interaction between different normative sources, that is collective agreement, administrative regulations and state legislation itself, in order for the funds to be operative. The Author takes also into consideration that the relevant discipline has an experimental nature; furthermore, he analyses the value of the guidelines given by the law in art. 2. Then, he goes into the first administrative regulation enacted to implement the system provided in art. 2. He finally questions the compatibility of these instruments with the constitutional principle of freedom of trade unions.
