The study examines the essential features of the so-called platform-based work, which is rapidly evolving into a major, potentially game-changing force in the labor market. From low-skilled, low-paid services (such as passenger transport) to highly skilled and high-paying project-based work (such as the development of artificial intelligence algorithms), a broad range of tasks can be carried out through a variety of digital platforms. Our paper discusses the platform-based content, working conditions, employment status, and advocacy problems. Terminological and methodological problems are dealt with in-depth in the course of the literature review, together with the 'gray areas' of work and employment regulation. To examine some of the complex dynamics of this fast-evolving arena, we focus on the unsuccessful market entry of the digital platform company Uber in Hungary 2016 and the relationship to institutional-regulatory platform-based work standards. Dilemmas relevant to the enforcement of labor law regarding platform-based work are also paid special attention to the study. Employing a digital workforce is a significant challenge not only for labor law regulation but also for stakeholder advocacy.
