Gender norms are the often unspoken expectations of the social environment towards a person and include assumptions of difference between the sexes/genders. Since these norms are produced through everyday interpersonal interactions, sex/gender is understood as socially constructed. In addition to assumptions about difference, gender norms also include assumptions about a hierarchy in which men are usually ascribed a higher position than women. These constructed assumptions of inequality support hierarchical relations of power and domination between the sexes/genders which contradict the principle of equal treatment. They lead to unequal opportunities for participation between the sexes/genders and promote discrimination.
