L'Unia chiede regole chiare che permettano di stabilire quando le condizioni meteorologiche avverse siano tali da imporre l'interruzione dei lavori edili. Malgrado la situazione climatica di questi giorni sia stata infatti particolarmente sfavorevole nella Svizzera interna, con forti venti e freddo pungente, agli operai non è stata concessa alcuna pausa.
Nella conferenza stampa tenuta a Berna è stato fatto l'esempio di un grande cantiere a Yverdon dove la risposta dell'impresa è stata che a -5° si può ancora usare il calcestruzzo. Operai presenti all'incontro hanno riferito delle numerose volte che sono stati costretti ad esercitare il mestiere in situazioni estreme. Le pressioni affinché i tempi di realizzazione pattuiti siano rispettati sono enormi, hanno spiegato, ricordando le salate penalità previste dai contratti tra il cliente e l'azienda.
