I don't think you need to go as far as globalization to understand that company loyalty is not something to take for granted. Howard Hughes used to say (back in the 1940s):
no don't tell me about those people, I don't want to know about their lifes. I can't sack someone who'd child has cancer.
In many organizations man has always been a cog*.
* as an aside - interesting how companies now go on about the snakeoil that is knowledge management. If knowledge is so important, why in times of crisis, do they shed their "most valuable resource"?
