Comparing ethnographic and interview data in three contrasting production arrangements in a labour-intensive factory in South China, this article argues that while the mobile phone constitutes a new contested terrain on the shop floor and facilitates control and resistance between capital and labour simultaneously, the dynamics of control and resistance is contingent upon the exact arrangements of production. While the management strictly prohibit line operators in the assembly line department from using their mobile phones, they turn a blind eye towards mobile phone use among workers in the hardware department, and mandate mobile workers who are not fixed at work stations in both departments to use mobile phones. Diverse managerial control tactics have generated different patterns of worker resistance. Workers in the assembly line department employ strategies to evade managerial surveillance and continue to use mobile phones at work covertly. They also contest the double standards of mobile phone use displayed by the management. Workers in the hardware department challenge the boundaries of legitimate mobile phone use, and mobile workers use tactics to escape being tracked down by the management via their mobile phones. Mobile phones also facilitate the strategy of resistance through exit among all workers.
