Sexual harassment can take two forms: quid pro quo harassment, where a person in authority makes unwelcome sexual advances or requests sexual favors in exchange for employment benefits; and hostile work environment harassment, where unwelcome sexual conduct substantially interferes with work or creates a hostile environment. Sexual harassment includes physical, verbal, and visual acts of a sexual nature such as unwanted touching, sexual comments or jokes, and displaying sexual images. Employers should establish clear anti-harassment policies, train employees, promptly investigate complaints, discipline offenders, and protect complainants to prevent sexual harassment in the workplace.
