It's not though, an Italian company has won a contract within the EU and is carrying out that contract with its own labour force which it is perfectly entitled to do.
If this is a problem maybe you should be questioning the reasons why it is so that companies from other EU states are more competative than those within the UK.
...which would then drag onto worldwide equality. I'm sure we could find workers for even less outside of the EU? Do you think we should beat ourselves up over why Africa is more competitive that the EU. Something tells me that you're answer is "Yes."
Britain can't change the world but she can make her own laws and life would be a lot easier if we just pulled out of the fucking EU.
