Marion Knaths has had a storybook career: at 19 she starts working as a nobody in a large corporation and at the age of 34 she is to become a board member of a large American corporation. She managed to step through the "glass ceiling" - today she passes on her insider knowledge and experience to others in lectures and seminars. Marion Knaths (*1968) studied at the Hamburg Business Academy and began her steep career at Otto Versand with the "Hamburg Model". At the age of 30, she changed to the DOB via the stations of disposition, head of controlling, head of marketing in the business unit purchasing children's outerwear. There she headed the "Young Fashion" project, became head of procurement and then head of procurement and business administration for women's wear. In 2004, she set up her own consulting company, sheboss, offering leadership seminars and coaching by women for women. She supports companies in bringing more women into leadership, management and top management. In her lectures, Marion Knaths unmasks the unofficial rules of the game that form and support the "glass ceiling" in a humorous and vivid way. Using many examples from everyday life, she illustrates how seriously the differences in male and female communication affect the chances of promotion. In doing so, she shows how women can skilfully use these differences if they understand the rules of male communication. In addition to excellent content, she also provides answers to the specific questions and experiences of women in a still male-dominated environment. Marion Knaths is characterised not only by her passionate commitment, but also by a tongue-in-cheek view of life's challenges. Thanks to a very figurative language, Marion Knaths manages to convey any topic, no matter how serious, in an amusing and understandable way.
