One of my cow-orkers recently told us a story from his last job working for (a large company you have all heard of). They were outsourcing stuff to India and had gotten 12 Indian engineers to come to England for 4 weeks training. Of the 12 that got on the plane, 10 showed up at their office - the others simply got off the plane and having gotten a free flight to England, disappeared. Of the 10 that got on the plane back, 8 reported to the office there - the other 2 went to other companies with $large_company on their CVs. Within 3 months, none of the original 12 were left.

The outsourcing went ahead anyway.
