Several years ago I worked in an industry where we had layoffs typically twice a year. I always enjoyed them in a bizarre way. It was exciting. I knew enough to realize that I could find another job and I knew also that the decision making was rather arbitrary so rather than worry about it, plan for it. Make contacts with other companies, save money, etc.
Like you say, it was interesting to note the differences among people. I was always disappointed by the politicking to improve survivability.
When the company announced they were closing our studio, rather than relocate, I asked to be laid off. I had already had a job lined up with a competitor starting the week after closure. So, I got a few months severance, double pay for the months leading to closure, and I transitioned in to a new job.
In my experience, banking on job security is a bad idea. It also taught me never to be loyal to a company. If you look at the leaders of any company, you will see they are less likely to be loyal as well.
The part that is annoying is that "caring" people act just as selfishly as "cold" people. Through every layoff, I've always been amused by how the "nice" people got the knives out when it came down to them or someone else. You could see them struggling with it, but at the end of the day all the niceness was just a veneer of convenience. Maybe that's why I enjoyed them.
