Sexual harassment is a form of discrimination that involves unwelcome sexual advances, requests for sexual favours, and other verbal or physical conduct of a sexual nature that explicitly or implicitly affects an individual's employment, unreasonably interferes with an individual's work performance, or creates an intimidating, hostile, or offensive work environment. It can occur in two main forms: quid pro quo harassment, where work benefits or conditions of employment are made contingent on sexual favours, and hostile environment harassment, where unwelcome sexual conduct, such as offensive touching, lewd comments, or the display of pornographic material, is severe or pervasive enough to create a hostile or abusive workplace. Sexual harassment is illegal in many countries and is recognised as a serious form of misconduct that can have significant negative impacts on the victim's psychological and professional well-being.
