The famous German film director Rainer Werner Fassbinder said: “I can sleep when I’m dead”. For a long time, sleep was considered as something for weaklings and slowpokes. To this day, a lot of managers boast of their ability to get by on little sleep, such as Marissa Mayer form Yahoo, Tesla Chief Executive Elon Musk or Donald Trump, US presidential nominee. But recent research shows that sleep has a significant impact on managers’ performance, on their physical health and on their social and emotional life. Should organisations therefore make sleep their business as they do already with other aspects of well-being? We interviewed sleep researcher Prof. Vicki Culpin from the private business school Ashridge Executive Education, who will be a keynote speaker at the exhibition Zukunft Personal in October.
