That's life. If you can't pick yourself up and roll with the punches, you're going to have a much harder time in other areas of your life. These co-workers didn't die, they got laid off and many will probably find better jobs and look back and realize what a favor DST did for them. They had the decision made for them.
Anyone who isn't looking for another job after this first wave of layoffs is seriously in an unhealthy way wrt to their job.
It's a job. All of you should always be ready to move on to the next job at any given time in life. It's called adapting to change and thriving in the process.
Only one thing constant in life, that's change.
Most of you fear change and it its making you undesirable as an employee.
