An associate of mine who had always done an outstanding job hired a junior person to handle some old tasks, while he himself took on some new ones. The subordinate did poor work. My associate’s reaction: “He has to make his own mistakes. That’s how he learns!” The problem with this is that the subordinate’s tuition is paid by his customers. And that is absolutely wrong. The responsibility for teaching the subordinate must be assumed by his supervisor, and not paid for by the customers of his organization, internal or external.
