Aims

WageIndicator aims to publish the content of Collective Bargaining Agreements on the national WageIndicator websites for web visitors to have access to the content of the Agreements. WageIndicator collects the texts of Collective Bargaining Agreements (CBAs) around the world. It then enters these in its CBA database, annotates relevant texts according to a coding scheme and publishes the text online, if possible. The database allows for analyses across CBAs.
