As someone said the other day- just shows we do need immigrants to do the jobs (yuk...doesn't bear thinking about) locals just won't contemplate (sorry, cheap)
foreign workers have always done jobs that locals won't do, though. Students grape-picking in France, backpackers working on the farms in Australia, working in bars, hotels, etc (although in Oz they are paid a fair wage and a contribution to their pension fund which is returned to them if they leave the country!).
The locals won't do some of the jobs there and if they do take them, they fail to turn up, won't work hard and are often hungover.
