can you appeal a job rejection?

Every few weeks or so, I'm contacted by a job candidate who asks me to reconsider our rejection of his or her application. This almost never works -- actually, I want to say "never" but there's one very, very limited case in which it might be okay to do.

Over at U.S. News & World Report today, I write about why you generally can't appeal a job rejection, and the one time where you can. Please check it out here and leave your own thoughts in the comments over there.
