This article illustrates the structural conditions of negotiation, cooperation and conflicts in the creative labour process. Using book cover design as an example, the author explores the project-team network formed by editors, designers and other social actors, and points out the informality of designers' works. Editors play the roles of coordinators and product checkers, keeping the editorial and selling rules but also allowing the designers to experiment and innovate. The innovation of designers, ultimately, would become the advantages for negotiation. On the other hand, the designers try to balance their individual creation, reputations and their livelihoods. The structural tension in the creative labour results from the contradiction between art creation and product selling, and the differences of employment positions. The polarization between famous designers and the reservation army of designers reveals the ethical and political issues of creative works that should be examined with a labour process approach.
