Abstract: [Purpose/Significance] This study aims to investigate food delivery riders' privacy concerns and protection in China, manifesting the significance of privacy protection for under-represented crowd workers in the gig economy, a relatively vulnerable group. [Design/Methodology] This study has employed a questionnaire survey to assess Chinese food delivery riders' privacy concerns in multiple dimensions, such as information collection, perceived surveillance, and perceived intrusion, and proposed corresponding protection measures. [Findings/ Conclusion] Chinese food delivery riders expressed numerous privacy concerns and many experienced privacy divulgences. Still, their awareness of the platform's data collection and the Personal Information Protection Law（PIPL）was insufficient. [Originality/Value] This paper revealed the complex correlations between the privacy concerns of Chinese food delivery riders in the gig economy and their knowledge about PIPL, highlighted that privacy protection law should be diverse and specific, and proposed that research on privacy user in gig economy should extend from consumer-oriented perspectives to cover some under-represented groups that are prone to be overlooked.
