I've heard "wins the lottery" as a less morbid metaphor for the same concept: one of your employees stops working in a low-probability event. Of course the higher-probability event is leaving their job (but somehow it's less polite to just say that); you usually get two weeks to hurriedly start documenting things, and with the current state of employee/employer relations you might easily get less. Or they might have several days of vacation saved up.
