The concept of gender is increasingly used in management today. It has also given rise to criticism and debate, sometimes stemming from confusion or a lack of understanding of the concept. This makes it all the more important to be familiar with the definition of gender and its relevance to management science. Initially, the concept of gender was proposed as a complement to the concept of sex. The concept of sex then refers to the biological differences between women and men, while the concept of gender refers to social differences.
