How do I keep my job away from the chopping block?

I’ve worked for my company for three tumultuous years, during which I have seen six people be dismissed – out of a staff of only 16. Everyone is worried, thinking “Am I next on the chopping block?”

I have always met or exceeded goals, I am well-liked, my subordinates perform well, and I have branched out to take on instructor duties.
