The paper analyses legal and contractual instruments which have gradually been envisaged to guarantee continuity of employment in case of loss of a service contract to a competitor. The point of tension is found in the discipline of transfers of undertakings, businesses or parts of businesses and in the low efficacy of the so-called second generation social clauses. Having regard to the judgments of the European Court of Justice, has been provided an interpretation of the art. 29, co. 3 Legislative Decree 273/2003, introduced in 2016 following a pre-litigation procedure against the Italian State.
