This article focuses on the debate surrounding constitutionalism that has been driven by a constitutionalist alliance of media reporters, intellectuals and lawyers since 2010, and follows its historical trajectory. It argues that this debate forms a discourse with a structuring absence, the roots of which can be traced back to the taboos surrounding the Cultural Revolution, the 1975 Constitution, and everything associated with them. The absence manifests itself in the silence on workers' right to strike, a right which was deleted from the 1982 Constitution in an attempt to correct the ultra-leftist anarchy of the Cultural Revolution. Previous and in contrast to that, there was a Maoist constitutional movement in the Cultural Revolution, represented by the 1975 Constitution, that aimed to protect the constituent power of the workers by legalizing their right to strike. Today, we are witnessing the rise of migrant workers as they struggle for trade union reform and collective bargaining with little support from the party-state or local trade unions. In this context, a third constitutional transformation should be considered that is not a return to the 1975 Constitution but which instead adds some elements which protect labour's right to strike to the 1982 Constitution.
