"The typical person being moved today is part of a two-career family. The other half of that equation is probably not being moved, so the corporate move comes down hard on the couple’s relationship at a very delicate point. It brings intolerable stress to bear on the accommodation they’re both striving to achieve to allow two full-fledged careers. That’s hitting below the belt. Modern couples won’t put up with it and they won’t forgive it. The company move might have been possible in the 1950s and 1960s. Today it is folly."
They also cite a case study of a major project at Bell Labs which was moved from New Jersey to Illinois. The authors interviewed the former manager of that project:
"I asked him what he saw as his main successes and failures as boss. “Forget the successes,” he said. “The failure was that move. You can’t believe what it cost us in turnover.” He went on to give some figures. The immediately calculable cost of the move was the number of people who quit before relocation day. Expressed as a percentage of those moved, this initial turnover was greater than the French losses in the trenches of World War I."
(FWIW, that's just one of many insights from that book - I highly recommend it.)
