The business risk that workaholism presents is an underestimated risk in companies and human resources management, which can develop into an existential threat to a business. In this empirical study, for the first time in German-speaking countries, workaholics were asked about their addiction indices and their effects on companies. In addition, operational influences were researched to determine their ability to cause or promote work addiction. A detailed risk analysis illustrates the risk potential of workaholism and its management challenges. The practice-oriented action guide shows opportunities to identify workaholics and gives managers pragmatic recommendations for action. Therefore, the challenges of workaholism can be faced in everyday business life.
