It’s also a “culture” issue (work ethic, respect: things like that).
At GE they told the same things to our employees when GE was opening a plant in NC. As expected, few were called
Where was the company moving jobs from?
I know a couple of guys that followed jobs with what eventually became Wells Fargo; they had been First Union employees in NJ, Wachovia employees in PA then VA, and Wells employees in Charlotte. With each move the group got smaller (guys with homes/families were unlikely or unable to move); eventually two remained.
