Same thing happened to me back in 1992. Company moved to Nuevo Laredo, MEX. I could have gone to Montgomery, AL, where we had no friends, I'd have had a new boss with whom there was a mutual dislike, more responsibility, more travel, no help, and other added responsibilities. My wife would have taken a $25K loss in pay.
Where were the benefits of moving someplace where we'd never be accepted? So we didn't go. Turn out there weren't any salary increases for over 3 years, too.
