After a mass firing, how should you feel?

I am sorry you had to go through that. It is unfortunate but mass firings are most often due to some other larger economic issue unrelated to your performance and unrelated to the performance of those your had to fire.

I am sure you are not happy with the situation. You will be going through a recovery phase. The first part of that is to realize that you were not in control and it is not your fault. The second part is to think about recovery. What do you have to do to get your self on track. That would include evaluating your career and whether staying at your company is a good idea.

The employees you had to let go are going through the same experience. They will be realizing it is nothing that they did and will work on where to continue their career. Having been through a number of these I am amazed at how everyone pursues their self interest and recover quickly. They spread out and find new positions quickly.. . So worry about your own recovery and know that all the people who lost their jobs will be searching and finding jobs.

Two more things: In the US mass firings are now called "Reduction in Force" or "RIF's" -- I think that is impart to make it sound less bad than mass firings. Also are you still employed? While I think we should be generous to others you do need to take care of yourself given the instability.

Good luck
