In the minds of many people, all it takes to discredit someone is to produce convincing unfalsifiable slander against them. To accuse a person or to make a claim against another is, to those who cannot think, i.e. management in general with few specific exceptions, the same to them as if the accused were guilty. In the business world, seemingly at least and in practice true from experience, people are presumed guilty unless proven innocent beyond a shadow of a doubt. When a person, especially one who works rather than one who socializes or just bosses others while they eat chicken nuggets and otherwise do absolutely nothing, is complained about, they are automatically under suspicion and anything they say is assumed to be a lie if it runs counter to the slander made against them. So, in the "wonderful" world of at-will employment, an accusation is the same as a crime.
