Abstract
The emergence of the gig economy has generated a new class of workers who are categorised as independent "partners" instead of employees with rights to labour protection. Triggered by observations of a protest movement by platform-based delivery riders in Thailand, we engaged in seven months of digital ethnographic research of riders' interactions online to understand the emergence of informal groups facilitating mutual aid and collective action. Civil society research has neglected to analyse such groups within the gig economy. The study finds that social media is a site for the development and contestation of identity narratives. We observed a "Hero" narrative that glorifies delivery riders' independent status and a "Worker" narrative that challenges riders' conditions. We argue that these collective identity narratives crucially facilitate or inhibit the emergence of labour-oriented civil society organisations, thus contributing to third sector research that examines civil society in the Global South.
