As the principal information centre on trade union policy on collective bargaining, the main task of the WSI Collective Agreement Archive is to track and analyse developments concerning collective agreements. Besides publishing regular status reports on current agreements, the Archive also produces special assessments. The Archive has an internet website
www.tarifvertrag.de providing access to information on specific collective agreements and giving overviews of developments pertaining to collective agreements in all the major sectors. Every year the Archive publishes an analysis of current policy developments relating to collective agreements - the "WSI-Tarifhandbuch".
