The facts are there is not a level playing field for the persons who choose to come here against those of us who are here by default.
I'm currently on a multimillion pound job, the plasters/boarders are all Eastern Europeans, many have admitted that they all live in shared houses, some subletting rooms to other EE's, we have had some turn up with suitcases, I kid you not, having been in the country two weeks. The company is run by EE's who employ only their fellows statesmen, the job has suffered tremendously, why? Because communication is dire, how they pass H&S is beyond me as they wouldn't understand "evacuate" unless they walked into the fire, also the standard of work is different to how we over here work so further complications, all this adds to frustration amongst other trades some of which are EE's (who can speak fluent English) the job will without a shadow of doubt overrun both in time and budget.
So with ten or more to a house sharing all the bills etc they can afford to undercut the average established English (and I use that lightly) tradesman. Now when that impacts on the indigenous person standard of living, be it income or home life then how can it be good for the economy? No it is good for those companies that seek to employ these people no one else benefits. I've actually spoke to some that do speak English and they talk of going home in a couple of years as they can't afford to stay as they don't wish to live 10 to a house forever.
when I actually ask a former Home Secretary at the time if he'd be prepared to live amongst these people with the way they live he replied no I'm fortunate not to have too!! Sums it up if you ask me.
