Should employers be required to provide paid leave for employees suffering from severe menstrual pain?

Spain recently became the first European country to mandate paid menstrual leave, sparking a global debate on workplace equity and biology. The core tension is between acknowledging debilitating pain (dysmenorrhea) as a specific medical need versus the fear that such policies make women "expensive" employees. Proponents argue it normalizes women's health and prevents burnout from working through pain. Opponents argue it creates a perverse incentive for employers to discriminate against women during hiring to avoid the cost and logistical hassle.
