ABSTRACT The existing literature on labor control of on-demand platforms primarily concentrates on algorithmic management. Based on the case study of Didi Chuxing, China’s ride-hailing giant, this article introduces some additional complexities into the dominant storyline by bringing two managerial elements to the fore, namely, labor intermediaries and communication technologies. Although both have long been integral to the control of flexible labor forces in the post-Fordist era, they remain underexplored in the context of the on-demand economy. I argue that labor intermediaries emerge as quick solutions to the indeterminacy of labor mobility power, a critical problem inherent in the just-in-time labor strategies that challenge on-demand platform companies. Communication technologies are crucial for the functioning of this mediated relationship, formulating a virtual space where daily managerial practices take place. Ultimately, I stress that, while the labor process of on-demand platforms represents a shift towards fluid workspace, it does not mean the elimination of the organization-based control that usually occurs in a physical and formal workspace. This case study urges scholars to understand labor control of on-demand platforms as a regime of hybridity that features both continuity and renewal of the various forms of managerial strategies common to flexible production.
