One of the pillars of European policy, and in particular of the Single Market, is the free movement of workers throughout the Union. This aim, including the non-discrimination of workers legally employed in a country different from that of their origin, cannot be achieved without a framework allowing the mutual understanding and transposition of professional qualifications and experiences among Member States, to "match the skills of a jobseeker and the requirements of an employer regardless of the different languages they might use" (see the EURES Taxonomy description).
