“The overall task of this paper is to elaborate a typology of the forms of labour that are needed for the production, circulation, and use of digital media. First, we engage with the question what labour is, how it differs from work, which basic dimensions it has and how these dimensions can be used for defining digital labour. Second, we introduce the theoretical notion of the mode of production as analytical tool for conceptualizing digital labour. Modes of production are dialectical units of relations of production and productive forces. Relations of production are the basic social relations that shape the economy. Productive forces are a combination of labour power, objects and instruments of work in a work process, in which new products are created. Third, we have a deeper look at dimensions of the work process and the conditions under which it takes place. We present a typology that identifies dimensions of working conditions. It is a general typology that can be used for the analysis of any production process. Fourth, we apply the typology of working conditions to the realm of digital labour and identify different forms of digital labour and the basic conditions, under which they take place. Finally, we discuss political implications of our analysis and what can be done to overcome bad working conditions that digital workers are facing today.”
