Around the world, myriad workers perform micro-tasks on online platforms to train and calibrate artificial intelligence solutions. Despite its apparent openness to anyone with basic skills, this form of crowd-work fails to fill gender gaps, and may even exacerbate them. We demonstrate this result in three steps. First, inequalities in both the professional and domestic spheres turn micro-tasking into a 'third shift' that adds to already heavy schedules. Second, the human and social capital of male and female workers differ-leaving women with fewer career prospects within a tech-driven workforce. Third, female micro-work reproduces relegation of women to lower-level computing work observed in the history of science and technology.

Introduction: The gendered dimension of work on micro-tasking platformsMicro-tasking platforms are digital infrastructures that fragment large data projects into small bits, and allocate them to masses of anonymous providers, each of them executing remotely a tiny part of the whole and receiving a small compensation for it. Examples of micro-tasks include labelling images, categorising messages, recording short sentences, and transcribing audio snippets. Generally simple and short, they nonetheless serve to meet the data needs of today's fast-growing artificial intelligence industry (Casilli, 2019;Tubaro & Casilli, 2019;Tubaro et al., 2020a).At first glance, these platforms appear ' gender neutral' and largely inclusive.Clients companies target unidentified and uncredited masses, and are typically given very limited access to individual workers' profiles (if at all). Under these conditions, employment discrimination is unlikely to occur -and indeed the nascent literature on digital platforms has mostly taken it as non-existent. Recently,
