The digital platform has created a new type of flexible employment model, whilst at the same time it has broken through the limitations of the traditional labor legal system. As a result, the online workers who make a living under the platform have lost the protection of the law. Platform discipline rules, as a documented manifestation of Digital Taylorism, are an important tool for platforms to use digital technology to control the labor of gig workers. However, this kind of rule eliminates the rights and interests of gig workers in the formal equality of civil contracts, and the resulting issues of oppression attract public attention. There exist limitations in constructing platform punishment rules based on classical contract theory. The current study believes that the relationship contract theory should be employed to deconstruct and correct current platform punishment rules, promote consensual correction, and to implement soft law to promote platforms to assume due obligations.
