This is a thesis about knowledge-intensive work and the organizational con-texts of such work. The specific objective is to analyze the geography of work. The geography of work may diverge from the geography of employ-ment when paid work is undertaken at the premises of client organizations, during commuting, on business trips, in external meetings, at home or in other places. The focus is on work practice and the perspective of everyday life. The study examines where knowledge workers are located and where knowledge work occurs. It is about what knowledge workers actually do. The everyday perspective is about the relationship between paid work and unpaid work. To understand the organization of knowledge-intensive work in a time–space context, different possibilities and constraints must be taken into con-sideration. This thesis has a time–geographical approach. The case study examines knowledge-intensive organizations located in central Stockholm. The organizations are in PR/communications, management consultancy, and research and development sectors. Both private and public sector organiza-tions are considered. The empirical study combines interviews, time diaries and questionnaires. The NVivo software program is employed to analyze the interview data. The main conclusion from the thesis is that in order to under-stand knowledge-intensive work, different factors such as relations, attitudes and norms need to be considered. These factors affect the organization of work, which in turn is affected by the choices, possibilities, constraints, ex-pectations and negotiations of different actors (i.e. employees, employers, family, clients and colleagues). The working time of the knowledge workers investigated in this study is mainly spent at the office of their employers. Social interaction with col-leagues and clients is an important part of their work. Work routines involve many meetings, both face-to-face and virtual. Face-to-face interactions play a crucial role in shaping the geography of work; teamwork is important. The knowledge workers in this study are “working long hours,” and the norm is to work more than what have been expected.
