Gender inequality continues to exist in many organisations, which leads to dysfunctional workplaces and an underexploitation of existing competence. The chapter discusses the most common failures in enforcing gender equality and explains terms such as glass ceiling and vertical-, horizontal-, and internal gender segregation. The chapter examines and deconstructs the most common arguments that are present in the debate on gender equality and ends with an argument for justice, but with a new twist: people who feel that they have been treated unjustly also take up an adversarial stance towards the organisation, irrespective of their gender. Justice is thus a matter of proper resource utilisation.
