The first Ghostwork project article, ‘Lost in the Crowd?’, was recently published in the European Journal of Industrial Relations. Within, we asked two questions: Where in Europe is microworking performed? Who is performing it? Based on the geolocation of 5,239 EU workers, we identify variation in the relative prevalence of microworking across the EU-27. Furthermore, we distinguish four different classes of microworkers in terms of worker diversity and income dependency. Identifying this geographic variation in prevalence and these different classes of microworkers suggests the importance of both worker heterogeneity and geographic contexts to the future study and regulation of microwork.
