Corporate social responsibility (CSR) is a popular phenomenon that originates at the margins of the legal system. How do CSR practices interact with the law? With the propagation of CSR instruments, the law struggles to prescribe these procedures while favouring an effective application of codes of conduct. Nevertheless, the motivations behind CSR practices stem primarily from a desire to reduce legal risk rather than from a wish to convey a good corporate image. The legal status of the codes is variable, and the jurisdictions participate in the implementation of these regulatory norms of corporate relations. While these acts are intended to protect the fundamental social rights of workers, they sometimes become new legal tools used to make workers subordinate to the corporate ethic. Is it desirable, then, to propose a legal framework for this purely spontaneous and voluntary social phenomenon?
