Retribuzione flessibile e contrattazione collettiva

Nel presente lavoro vengono esaminate le forme impiegate dalla contrattazione collettiva per rendere aleatorio il trattamento economico dei lavoratori subordinati. Dapprima ci si occupa del limite alla “flessibilizzazione” della retribuzione dei lavoratori subordinati che viene individuato nella “retribuzione sufficiente” di cui all’art. 36 Cost., qualificata come elemento essenziale del contratto. Di seguito si sofferma l’attenzione sulla retribuzione di produttività e di redditività dei lavoratori del settore privato e sul trattamento accessorio dei dipendenti pubblici privatizzati. Nonostante a queste quote della retribuzione sia astrattamente conferita una funzione incentivante, in concreto non la svolgono: nel lavoro privato a causa della politica egualitaria del sindacato e della “modalità” di determinazione degli obiettivi, nel lavoro pubblico perché questa parte della retribuzione è stata tradizionalmente erogata “a pioggia”. Nel terzo capitolo si prendono in considerazione le liti che possono sorgere se, nel periodo di tempo che va dalla fissazione degli obiettivi a quando si deve verificare il loro conseguimento, il datore di lavoro apporti modifiche organizzative in grado di ripercuotersi sulla capacità dei prestatori di raggiungere i risultati. Al fine di risolvere tale questione, in chiusura del secondo capitolo, la clausola in tema di retribuzione flessibile è stata classificata come condizione sospensiva in quanto una parte del trattamento economico, aggiuntiva alla retribuzione “base”, viene subordinata al conseguimento di obiettivi di produttività e redditività qualificabili come eventi futuri ed incerti. Tale qualificazione è volta a consentire l’applicazione dell’art. 1359 c.c. nelle controversie sopra descritte: se i lavoratori non conseguono gli obiettivi a causa di modifiche che il datore di lavoro ha apportato all’organizzazione, si può fingere che l’evento (che non si è verificato per una condotta imputabile al datore di lavoro) si sia verificato e, di conseguenza, erogare la retribuzione di risultato ai prestatori.

I rapporti tra contratti collettivi di diverso livello nel settore privato

L’elaborato esamina il tema del concorso e del conflitto tra contratti collettivi di diverso livello nel settore privato. Partendo da un’impostazione complessiva del fenomeno della contrattazione collettiva, oltre che da una riflessione sulla natura e sul ruolo della contrattazione integrativa, il lavoro si propone di individuare un criterio di risoluzione del conflitto. In una prima parte della ricerca sono stati individuati e studiati i modelli di rapporti tra livelli definiti negli accordi interconfederali e nei contratti di categoria. Nello studio della regolamentazione interna al sistema sindacale si è considerato la natura delle relative clausole. Queste ultime hanno valenza obbligatoria e, per tale motivo, non sono idonee a risolvere l’eventuale conflitto tra livelli contrattuali. Si è reso quindi necessario considerare i criteri esterni di risoluzione del conflitto elaborati dalla dottrina e della giurisprudenza. Tra i vari criteri elaborati, ci si è soffermati sul criterio di specialità, sulla sua natura e sulla sua funzione. Più nello specifico, si è ritenuto il principio di specialità un principio generale dell’ordinamento giuridico, applicabile anche al conflitto tra contratti di diverso livello. Alla luce del principio di specialità, si è ricostruito il rapporto tra livelli, anche in ipotesi di contrattazione separata e di negoziazione operante su rinvio legislativo. Infine, nell’ultimo capitolo si è esaminato l’art. 8 della L. 148/2011. Ci si è interrogati sulla compatibilità di tale norma con l’impostazione complessiva del tema del rapporto tra contratti di diverso livello e sui suoi riflessi sulla questione del conflitto.

The role of collective action in the provision of agri-environmental public goods: theoretical development through case studies in Italy

The thesis aims at analysing the role of collective action as a viable alternative to the traditional forms of intervention in agriculture in order to encourage the provision of agri-environmental public goods. Which are the main benefits of collective action, in terms of effectiveness and efficiency, compared to traditional market or public intervention policies? What are the drivers that encourage farmers to participate into collective action? To what extent it is possible to incorporate collective aspects into policies aimed at providing agri-environmental public goods? With the objective of addressing these research questions, the thesis is articulated in two levels: a theoretical analysis on the role of collective action in the provision of public goods and a specific investigation of two local initiative,s were an approach collective management of agro-environmental resources was successfully implemented. The first case study concerns a project named “Custodians of the Territory”, developed by the local agency in Tuscany “Comunità Montana Media Valle del Serchio”, which settled for an agreement with local farmers for a collective provision of environmental services related to the hydro-geological management of the district. The second case study is related to the territorial agri-environmental agreement experimented in Valdaso (Marche), where local farmers have adopted integrated pest management practices collectively with the aim of reducing the environmental impact of their farming practices. The analysis of these initiatives, carried out through participatory methods (Rapid Rural Appraisal), allowed developing a theoretical discussion on the role of innovative tools (such as co-production and co-management) in the provision of agri-environmental public goods. The case studies also provided some recommendations on the government intervention and policies needed to promote successful collective action for the provision of agri-environmental public goods.

The social construction of cooperation: exchange, identification and collective intentions within the organization

My aim is to develop a theory of cooperation within the organization and empirically test it. Drawing upon social exchange theory, social identity theory, the idea of collective intentions, and social constructivism, the main assumption of my work implies that both cooperation and the organization itself are continually shaped and restructured by actions, judgments, and symbolic interpretations of the parties involved. Therefore, I propose that the decision to cooperate, expressed say as an intention to cooperate, reflects and depends on a three step social process shaped by the interpretations of the actors involved. The first step entails an instrumental evaluation of cooperation in terms of social exchange. In the second step, this “social calculus” is translated into cognitive, emotional and evaluative reactions directed toward the organization. Finally, once the identification process is completed and membership awareness is established, I propose that individuals will start to think largely in terms of “We” instead of “I”. Self-goals are redefined at the collective level, and the outcomes for self, others, and the organization become practically interchangeable. I decided to apply my theory to an important cooperative problem in management research: knowledge exchange within organizations. Hence, I conducted a quantitative survey among the members of the virtual community, “www.borse.it” (n=108). Within this community, members freely decide to exchange their knowledge about the stock market among themselves. Because of the confirmatory requirements and the structural complexity of the theory proposed (i.e., the proposal that instrumental evaluations will induce social identity and this in turn will causes collective intentions), I use Structural Equation Modeling to test all hypotheses in this dissertation. The empirical survey-based study found support for the theory of cooperation proposed in this dissertation. The findings suggest that an appropriate conceptualization of the decision to exchange knowledge is one where collective intentions depend proximally on social identity (i.e., cognitive identification, affective commitment, and evaluative engagement) with the organization, and this identity depends on instrumental evaluations of cooperators (i.e., perceived value of the knowledge received, assessment of past reciprocity, expected reciprocity, and expected social outcomes of the exchange). Furthermore, I find that social identity fully mediates the effects of instrumental motives on collective intentions.

Collective effects for the LHC injectors: non-ultrarelativistic approaches

The upgrade of the CERN accelerator complex has been planned in order to further increase the LHC performances in exploring new physics frontiers. One of the main limitations to the upgrade is represented by the collective instabilities. These are intensity dependent phenomena triggered by electromagnetic fields excited by the interaction of the beam with its surrounding. These fields are represented via wake fields in time domain or impedances in frequency domain. Impedances are usually studied assuming ultrarelativistic bunches while we mainly explored low and medium energy regimes in the LHC injector chain. In a non-ultrarelativistic framework we carried out a complete study of the impedance structure of the PSB which accelerates proton bunches up to 1.4 GeV. We measured the imaginary part of the impedance which creates betatron tune shift. We introduced a parabolic bunch model which together with dedicated measurements allowed us to point to the resistive wall impedance as the source of one of the main PSB instability. These results are particularly useful for the design of efficient transverse instability dampers. We developed a macroparticle code to study the effect of the space charge on intensity dependent instabilities. Carrying out the analysis of the bunch modes we proved that the damping effects caused by the space charge, which has been modelled with semi-analytical method and using symplectic high order schemes, can increase the bunch intensity threshold. Numerical libraries have been also developed in order to study, via numerical simulations of the bunches, the impedance of the whole CERN accelerator complex. On a different note, the experiment CNGS at CERN, requires high-intensity beams. We calculated the interpolating Hamiltonian of the beam for highly non-linear lattices. These calculations provide the ground for theoretical and numerical studies aiming to improve the CNGS beam extraction from the PS to the SPS.

'Defending the rights'. An integrated model of collective action for "public water" in Italy

In many communities, supplying water for the people is a huge task and the fact that this essential service can be carried out by the private sector respecting the right to water, is a debated issue. This dissertation investigates the mechanisms through which a 'perceived rights violation' - which represents a specific form of perceived injustice which derives from the violation of absolute moral principles – can promote collective action. Indeed, literature on morality and collective action suggests that even if many people apparently sustain high moral principles (like human rights), only a minority decides to act in order to defend them. Taking advantage of the political situation in Italy, and the recent mobilization for "public water" we hypothesized that, because of its "sacred value", the perceived violation of the right to water facilitates identification with the social movement and activism. Through five studies adopting qualitative and quantitative methods, we confirmed our hypotheses demonstrating that the perceived violation of the right to water can sustain activism and it can influence vote intentions at the referendum for 'public water'. This path to collective action coexists with other 'classical' predictors of collective action, like instrumental factors (personal advantages, efficacy beliefs) and anger. The perceived rights violation can derive both from personal values (i.e. universalism) and external factors (i.e. a mobilization campaign). Furthermore, we demonstrated that it is possible to enhance the perceived violation of the right to water and anger through a specifically designed communication campaign. The final chapter summarizes the main findings and discusses the results, suggesting some innovative line of research for collective action literature.

L’autotutela collettiva tra ipotesi di revisione della disciplina nazionale e prospettive europee

Nel presente lavoro viene trattato il delicato tema dell’autotutela collettiva, nell’intersezione tra ipotesi di revisione nazionale e prospettive europee. Dapprima viene ricostruita l’evoluzione della valutazione del conflitto collettivo nell’ordinamento giuridico italiano ed effettuata una ricognizione delle diverse manifestazioni del conflitto collettivo ivi riscontrabili. Il tentativo è quello di superare i limiti di una trattazione ristretta allo sciopero e di verificare la perdurante validità della tradizionale nozione di sciopero, intesa esclusivamente come astensione collettiva dalle prestazioni di lavoro. In un secondo capitolo vengono esaminati i disegni di legge di riforma in materia di conflitto collettivo, presentati nel corso della XVI legislatura e le clausole, incidenti sulla medesima materia, rinvenibili nell’Accordo interconfederale del 28 giugno 2011 e negli accordi FIAT del 2010, relativi agli stabilimenti di Pomigliano D’Arco e Mirafiori. Alla luce di tali materiali, si riesaminano le tematiche della titolarità individuale del diritto di sciopero, delle clausole di tregua e delle procedure arbitrali e conciliative. Successivamente, viene esaminata la produzione legislativa e giurisprudenziale comunitaria in tema di conflitto collettivo. Il confronto con l’ordinamento nazionale consente di mettere criticamente in luce il diverso rapporto tra mercato e diritti d’azione collettiva e di rilevare che nell’ordinamento comunitario la giurisprudenza della Corte di giustizia abbia introdotto limiti eccessivi al dispiegarsi dei diritti sociali in esame. Da ultimo, vengono formulate alcune considerazioni conclusive. Criticamente viene rilevato come, in tempi di globalizzazione, non viene prestata sufficiente attenzione alla valorizzazione del conflitto collettivo, come motore dell’emancipazione e del progresso sociale.

A threshold hypothesis of institutional change: collective action in the Italian Alps during the 13th - 19th centuries.

This dissertation is about collective action issues in common property resources. Its focus is the “threshold hypothesis,” which posits the existence of a threshold in group size that drives the process of institutional change. This hypothesis is tested using a six-century dataset concerning the management of the commons by hundreds of communities in the Italian Alps. The analysis seeks to determine the group size threshold and the institutional changes that occur when groups cross this threshold. There are five main findings. First, the number of individuals in villages remained stable for six centuries, despite the population in the region tripling in the same period. Second, the longitudinal analysis of face-to-face assemblies and community size led to the empirical identification of a threshold size that triggered the transition from informal to more formal regimes to manage common property resources. Third, when groups increased in size, gradual organizational changes took place: large groups split into independent subgroups or structured interactions into multiple layers while maintaining a single formal organization. Fourth, resource heterogeneity seemed to have had no significant impact on various institutional characteristics. Fifth, social heterogeneity showed statistically significant impacts, especially on institutional complexity, consensus, and the relative importance of governance rules versus resource management rules. Overall, the empirical evidence from this research supports the “threshold hypothesis.” These findings shed light on the rationale of institutional change in common property regimes, and clarify the mechanisms of collective action in traditional societies. Further research may generalize these conclusions to other domains of collective action and to present-day applications.

Percieved Organizational Efficacy in Internationalized Companies: Application of Competing Values Approach and Collective Efficacy

This dissertation focuses on “organizational efficacy”, in particular on employees’ beliefs of organizational capacity to be efficacious. Organizational efficacy is considered from two perspectives – competing values approach and collective efficacy, and evaluated in internationalized companies. The dissertation is composed of three studies. The data were collected in thirteen Italian companies on different stages of internationalization for a total number of respondents is 358. In the first study the factorial validity of the competing values instrument (Rohrbaugh, 1981) was investigated and confirmed. Two scales were used to measure collective efficacy: a general collective efficacy scale (Bohn, 2010), and a specific collective efficacy scale, developed following suggestions of Borgogni et al. (2001), it evaluates employees’ beliefs of efficacy of organizations in the international market. The findings suggest that competing values and collective organizational efficacy instruments may provide a multi-faceted measurement of employees’ beliefs of organizational efficacy. The second study examined the relationship between organizational efficacy and collective work engagement. To measure collective work engagement the UWES-9 (Schaufeli & Bakker, 2003) was adapted at the group level; its factor structure and reliability were similar to the standard UWES-9. The findings suggest that organizational efficacy fully predicts collective work engagement. Also we investigated whether leadership moderates the relationship between organizational efficacy and collective work engagement. We operationalized leadership style with MLQ (Bass & Avolio, 1995); the results suggest that intellectual stimulation and idealized influence (transformational leadership) and contingent reward (transactional leadership) enhance the impact of organizational efficacy on collective work engagement. In the third study we investigated organizational efficacy and collective work engagement in internationalized companies. The findings show that beliefs of organizational efficacy vary across companies in different stages of internationalization, while no significant difference was found for collective work engagement. Limitations, practical implications and future studies are discussed in the conclusion.
