What is the definition of sex discrimination?

Sex discrimination refers to the unjust or prejudicial treatment of individuals based on their sex or gender. This can manifest in various contexts, including employment, education, and healthcare, where individuals may face disparities in opportunities, pay, or access to resources solely due to their gender. It encompasses both overt acts of discrimination and more subtle forms of bias that reinforce gender stereotypes. Such discrimination is often addressed through laws and policies aimed at promoting equality and preventing gender-based injustices.
