This paper seeks to understand the transmission and reception of legal rules as a component of the regulatory compliance process. It adopts a frontline approach to regulatory compliance that traces the grassroot functioning of compliance processes from regulator, to compliance managers to individual employees. Through a multilevel and multi-sited ethnography of worker safety protection in Chinese construction industry, this paper shows that in the cases studied there is a fundamental disconnect in the transmission and reception of law from regulator to (...) organization and within the regulated organization. Yet at the same time, the paper finds that employees did comply with the law, and that thus compliance can exist without a full transmission and reception of legal rules into and within the regulated organization. By expanding the frontline approach to study regulation and compliance to look at the grassroots operation across three different frontlines, this study has been able to assess the legal assumptions inherent in existing regulatory compliance research. Not only does it find that compliance in these cases was not a top-down process and that we need to look at the grassroots operation inside organizations, it also shows that law does not always play a central role in regulatory compliance and that we need to reassess the implicit focus on law in regulatory compliance scholarship.
