The European Parliament and the Council took a courageous step toward prohibiting sexual harassment throughout workplaces in the European Union EU when it enacted amendments to the 1976 Equal Treatment Directive. The public policy objective of Directive 2002/73/EC is to harmonize the Member States' laws regarding the equal treatment of men and women. According to the Directive, sexual harassment will be recognized as a form of gender-based discrimination throughout the EU. Turkish new labor code contains articles targeting to prevent sexual harassment. However the new code doesn’t define sexual harassment. After examining sexual harassment in comparative law, the author concludes that, this concept should be defined according to EU law, as a “unwanted conduct related to the sex of a person occur[ring] with the purpose or effect of violating the dignity of a person, and of creating an intimidating, hostile, degrading, humiliating or offensive environment”. The author also stresses the importance of the establishment of the liability of the employer.
