Whistleblowing in Italy : rights and protections for employees
No full textThis paper examines the whistleblowing in the Italian legal system. In the lack ofproper rules on such a phenomenon (quite uncommon in the Italian social reality, also due to cultural reasons) except for the civil servants, the paper goes on analysing, on the one hand, the provision applicable to the civil servants (i.e. art. 54 of the Legislative Decree no. 165/2001), and on the other hand, the instruments provided for by the Italian legal system as general principles, which can be applied by the judge in order to protect the whistleblowers in the private sector (in particular the rules against retaliatory and discriminatory acts and mobbing). The Author stresses that the recalled protection, although effective (also after the so-called 'Monti's reform', id est the Law No. 92/2012), could be not sufficient both because of the allocation of the burden of proof, and because it is applicable to the employees and only partially (as the Author explains in the last paragraph) to the whistleblowing in the context of self-employment. Then the paper analyses the balancing performed by the Italian caselaw between the right to information and the right of criticism, on one side, and the right to secrecy set forth by law in respect of business facts and information, and the personality rights granted to the employer by the Constitution,on the other side. Finally the paper deals with the applicable procedures, introduced by disciplinary codes, also according to the Legislative Decree No. 231/2001, and the problems related to internal reporting systems, in particular the balancing between the needs for the whistleblower's protection and the positive law in the matter of protection of the privacy of the person to whom the complaint relates according to the Legislative Decree No. 196/2003
L'obbligo di ripescaggio nel licenziamento per giustificato motivo oggettivo di tipo economico alla luce del Jobs Act
No full textIl contributo si interroga sul ruolo che, in seguito alle ultime riforme del lavoro, ha assunto il cd. ripescaggio all’interno del licenziamento per giustificato motivo oggettivo di tipo economico. Nella prima parte del saggio, l’esame dei più recenti orientamenti della giurisprudenza, in particolare di quella sull’onere della prova, conduce alla conclusione che il ripescaggio è parte integrante del gmo posto dall’art. 3, l. 604/1966 inteso quale limite interno (o causale) dell’atto di licenziamento, in quanto costituisce il nesso causale negativofra riorganizzazione disposta dal datore e mansioni del lavoratore. Il significato così assunto dal gmo, pur costituendo certo un limite “minimale” dell’atto di licenziamento, risulta comunque conforme ai principi costituzionali, eurounitari e internazionali, secondo l’interpretazione consolidatasi fino ad oggi. La seconda parte del lavoro analizza come la nuova disciplina dello ius variandi (art. 2103 c.c. come modificato dall’art. 3, d.lgs. 81/2015) impatta sulla struttura e sull’ampiezza del ripescaggio. Partendo dal presupposto che il nuovo testo dell’art. 2103 c.c. amplia il debito del lavoratore, includendovi tutte le mansioni appartenenti al medesimo livello di inquadramento rispetto alle mansioni di assunzione (1 co.) e le mansioni del livello immediatamente inferiore (co. 2) – l’A. giunge alla conclusione che il ripescaggio costituisce oggi oggetto di un vero e proprio onere e si estende a tutte le mansioni che integrano il debito di lavoro. Il datore di lavoro infatti ha l’onere, a pena di ingiustificatezza del licenziamento, di cooperare all’adempimento del lavoratore e, dunque, di adibire il lavoratore, nell’esercizio del proprio potere direttivo, ad una delle mansioni dovute, dello stesso livello o del livello immediatamente inferiore rispetto alle mansioni di assunzione. Il mancato rispetto del ripescaggio, così trasformato dall’art. 2103 nuovo testo c.c., è poi corredato da un successivo ed autonomo obbligo di formazione, che grava sul datore di lavoro. Infine, a corollario del ragionamento, l’A. ritiene che il “fatto giuridico” la cui “manifesta insussistenza” dà luogo, ai sensi dell’art. 18, co. 5, St. lav. alla tutela reintegratoria attenuata includa anche il mancato rispetto del ripescaggio, nell’accezione risultante dal combinato disposto dell’art. 3 l. 604/1966 e art. 2103 nuovo testo c.cTHE DUTY OF «REPECHAGE» IN THE DISMISSAL FOR OBJECTIVE ECONOMIC REASONS IN THE LIGHT OF THE JOBS ACT REFORM.
The essay focuses on the role of repêchage in the definition of the dismissal for objective economic reasons after the recent Italian labour law reforms. In the first part of the essay, moving from the analysis of the case-law, especially the one concerning the burden of proof, the author highlights that repêchage is part of the definition of dismissal for objective economic reasons as provided for by Art. 3 Law no. 604/1966, as it represents the causal link between the reorganization of the firm and the workers’ skills. This is in line with both the Italian Constitution and the principles at supranational and international level. In the second part of the essay, the author analyses how the new text of Art. no. 2103 c.c. (as reformed by delegated decree no. 81/2015) affects the duty of repêchage. According to the author, the new art. 2103, broadening the range of tasks the employee can be assigned to in the workplace, has also broadened the notion of repêchage. In her conclusive remarks, she argues that an employer’s failure to fulfil the duty of repêchage, should lead to the reinstatement of the employee under art. 18, co. 5, St. la
Il controllo a distanza dell’attività dei lavoratori dopo il “Jobs Act” (art. 23 D.Lgs. 151/2015) : spunti per un dibattito
No full textL’introduzione mira a offrire una panoramica del nuovo art. 4 St.lav., in materia di potere di controllo del datore di lavoro, recentemente modificato dall’ultima riforma del lavoro (c.d. Jobs Act).
In particolare, dopo una sommaria esposizione delle ragioni sottostanti la nuova norma, volte ad adeguare il potere di controllo del datore di lavoro all’evoluzione dei dispositivi tecnologici presenti sul luogo di lavoro, l’Autrice individua e si sofferma, in una prospettiva critica, sulle eterogenee e complesse questioni interpretative poste dalla novella.The introduction aims at giving an overview of the new article 4 of the
Worker’s Statute (Law no. 300/1970), concerning the employer’s monitoring
powers, as recently reformed by the latest Italian Labour Reform (the so called
Jobs Act).
In particular, after a brief explanation of the rationale underlying the new
rule, in order to make the employer’s control power compatible with the
improvement of technological tools in the workplace, the Author critically lists
and takes into consideration the heterogeneous and complicated interpretative
issues raised by the brand new reform
Il licenziamento nullo perchè discriminatorio, intimato in violazione di disposizioni di legge o in forma orale
No full textL’articolo esamina le varie forme di licenziamento nulle ai sensi del Jobs Act (licenziamento discriminatorio; licenziamento per ritorsione; licenziamento per violazione di legge; licenziamento per disabilità fisica e psichica; licenziamento per mancato superamento del periodo di comporto; licenziamento intimato in forma orale) sia al fine di definire i confini delle varie figure – anche rispetto alla nozione di licenziamento ingiustificato – sia per dipanare la questione delle tutele applicabili. Tale secondo problema è rilevante perché il Jobs Act a fronte delle varie ipotesi di licenziamento nullo non sempre esplicita la forma di tutela applicabile. Nel contributo l’A. sostiene l’idea che – benchè sia indubbio che in via generale il Jobs Act ha elevato a regola la tutela indennitaria e ha relegato ad eccezione la tutela reintegratoria – tuttavia con specifico riferimento all’area del licenziamento nullo esso ha riconfermato la centralità della tutela reintegratoria in considerazione dei particolari interessi della persona del lavoratore che entrano in gioco. Ne deriva che le varie ipotesi di licenziamento nullo – anche ove la legge non contempli una previsione specifica; sono soggette alla tutela reintegratoria ex art. 18 St.lav. o alla tutela reintegratoria “di diritto comune”.The article examines the various forms of dismissal void under the Jobs Act (discriminatory dismissal, dismissal for retaliation, dismissal for violation of the law, dismissal for physical and mental disability, dismissal for failure to exceed the period of compensation, dismissal announced orally) in order to define the boundaries of the various figures; also with respect to the notion of unfair dismissal; and to solve the problem of the applicable protections. This second problem is relevant because the Jobs Act in the face of the various hypotheses of invalid dismissal does not always explicitly the form of protection applicable. In the contribution, the Author supports the idea that; although it is undoubted that in general the Jobs Act has elevated to rule the indemnity protection and has relegated to exception the reinstatement protection; however, with specific reference to the area of invalid dismissal it has reconfirmed the centrality of the reinstatement protection in view of the particular interests of the person of the worker who come into play. It follows that the various hypotheses of invalid dismissal; even where the law does not provide for a specific provision; are subject to the reintegration protection pursuant to art. 18 of Statuto dei Lavoratori or to the reintegration protection "under common law
Improved pool fire-initiated domino effect assessment in atmospheric tank farms using structural response
No full textDomino effects are severe accident scenarios affecting storage tanks and are often initiated by pool fires. Flame engulfment and heat radiation are the two major sources triggering domino effect. Threshold-based and probit-based methods are widely used to assess the possibility and probability of a secondary accident. These methods are also a part of advanced methods devoted to examining synergic or coupling effects. The current work examines (i) how effective the threshold-based methods are and (ii) how accurate the current time to failure (TTF) estimation models are, which are the basis of probit-based methods. The results suggest that threshold-based methods are not pertinent for the quantitative assessment of domino effect and that significant improvement can be made in the existing TTF prediction models using site-specific structural response data. A new set of equations for TTF estimation using data analytics is proposed. Application to 4,080 pool fire scenarios demonstrates that the newly developed model can improve the TTF prediction performance compared to the existing models (around 22% in terms of R2). In addition, a method has been proposed and validated to correlate time with the failure probability for time-dependent domino effect assessment, which is a limitation of probit-based methods
Dynamic Domino Effect Assessment (D2EA) in tank farms using a machine learning-based approach
No full textThe current work presents a Dynamic Domino Effect Assessment (D2EA) methodology for chemical storage tank farms. While the application of the proposed approach is focused on atmospheric tanks, it applies as well to pressurized tanks. It utilizes the temperature and time-dependent material strength property (yield strength) as a structural health indicator. The D2EA methodology uses random forest (RF) and feed-forward neural network (FFNN) to predict yield strength during fire exposure and applies the predicted yield strength to dynamic failure assessment. A lumped parameter model generates datasets to train the dynamic failure prediction model. Two case studies have been used to demonstrate how the method can be used. The results suggest that RF and FFNN can predict gamma distribution-aided dynamic failure probability assessment. The RF is a better tool than FFNN due to its lower computational cost and good performance. The current work will be helpful in the design and operation of tank farms - an essential and critical infrastructure
Feasibility of fisheries co-management in Africa
No full textThe current, highly centralized approach to fisheries management seems to be incapable of coping with escalating resource depletion and environmental degradation. Co-management has been identified as an alternative. This paper compares various approaches to fisheries management and discusses their performance in relation to the nature of the fishery. It is concluded that in African fisheries, stringent institutional arrangements, poor human, technical and financial resources, and a limited time frame often thwart co-management approaches. However, with the right conditions and prerequisites, comanagement can be successful in improving compliance with regulations and maintaining or enhancing the quality of the resource. The paper brings out the issues that require further research.Fishery management, Community involvement, Fishery regulations, Sociological aspects, Africa,
Factors Associated to Purchase of Quality-Labelled Beef
No full textThe aim of the present study is to identify the factors associated to purchase of quality-labelled beef. For this purpose a total of 364 surveys were carried out on buyers of beef in three Spanish cities. The sample was divided into three groups of buyers according to the beef purchasing habits with a quality label. A logistic regression analysis was used to estimate the differences between groups. The results show the importance of the production region as a quality aspect. Income level, association of quality-labelled beef with “guarantee and tradition” aspects, purchasing frequency, place of purchase, production systems and lifestyles are all variables that enabled us to establish differences between groups.beef quality, quality label, consumer perception, Demand and Price Analysis,
