Full edition for public use. INFO-POW: Information Channels Mapping Tool Cross-national Dataset is the outcome of the data collection of existing information channels for posting companies in the five project countries (Austria, Belgium, Italy, Slovenia, and Slovakia). The dataset systematically identifies existing information channels and maps different dimensions and characteristics of the currently available information online and offline. The dataset maps information channels targeting companies that are active in the posting of workers within the EU. The data promotes the evidence basis through collecting and evaluating existing information sources specific to the posting process and posted workers' working conditions. In this way, the dataset allows researchers and stakeholders alike to identify the comparative differences in the information provided within and between countries and systematically observe the gaps in available information on the posting of workers.
