Tenured economics professor Bryan Caplan recently asked on his blog, "Why don't more people get fired?" Caplan is a blatant hypocrit, a libertarian who makes his money off the people's taxes, but he raises an interesting question. Replacing the weakest workers is a proven formula for success. It worked for GE and the 1961 Cincinnati Reds, for two examples. But I think there are two reasons, somewhat connected, why employers are slow to fire. One is people in general dislike any type of change and the second is there's no guarantee the person you hire will prove an improvement. But maybe you should take the advice Ingram Walters always give attendees at the NABD conference: "Go home and fire somebody!"
