In this thesis, I study the use of emotion in strategizing by observing how a team of consultants craft a process predicated on extensive emotion work. The strategizing process attempts the effortful working on, and with, the emotions of, and emotional dynamics between, clients of large organisations as a 3-to-5-year organisation-wide strategic plan is created. Accomplishing the process requires the consultants to engage in their own intense emotion work. The strategizing process aims to both materialise a strategy and mobilise clients for strategic action. Drawing from 21 months of ethnographic fieldwork, I find that the emotion work takes place across eight episodes as the consultants construct an intense emotional configuration during strategy formulation – firstly with executives and then with executives and their subordinates. I theorise a model for the intense emotional configuration produced by the emotion work – an emotional battery – made of a negative emotional pole which repels clients from the status quo and a positive emotional pole which attracts them. The contrast between the poles can create an attack mode which mobilises clients for strategic action. I theorise that the emotional battery requires highly socially ordered emotion work. I provide a model of how the conditions for emotion work are crafted as the consultants combine nine elements used to drive the effortful shaping of clients’ emotions towards, and thoughts about, the past, present, and future of the organisation. I find that emotion work during the strategizing process is designed to minimise resistance to strategic action. The intensity of the emotional battery either attracts or repels clients, forcing them to decide whether to stay and support the strategic plan or to leave the organisation. Finally, I identify the hidden implications and unanticipated effects of the strategizing process and the ongoing use of the identified elements.
