A bill of law (amendments to the Gender Equality Act No. 10/2008) was passed by the Icelandic Parliament (Althingi) with a vast majority on June 1st 2017 and came into force on January 1st 2018. Companies and institutions employing 25 or more workers, on an annual basis, are required to obtain equal pay certification of their equal pay systems and the implementation thereof. The purpose of this obligatory certification is to enforce the current legislation prohibiting discriminatory practices based on gender and requiring women and men working for the same employer to be paid equal wages and enjoy equal terms of employment for the same jobs or jobs of equal value.
