There are no dumb questions, and don't stop asking until you're satisfied with the answer. This hit close to home recently.
A friend of ours sells books to school libraries. Because of the lousy economy and because the book market is going more and more digital, her income is shrinking along with her sales. The company is in the midst of restructuring, and our friend fully expects that she and many other salespeople are about to be unemployed.
