Over the last three decades work and employment in the private and public sector are increasingly subject to marketization processes. A defining feature of marketized employment is the rise of performance management systems (PMS). This article utilizes a novel framework of Sayer’s moral economy approach and labour process theory to explore the changing nature of bank work and social relationships between branch managers and branch workers before and after the implementation of PMS in UK banks. This article illustrates how the social and moral texture of the social relationships between branch workers and their managers deteriorated after the implementation of PMS, resulting in the rise of hostile forms of engagement.
