The work-related characteristics of an individual act as pegs around which other nonwork activities are scheduled on a day-to-day basis. In this paper, four dimensions of the medium- to long-range work arrangements that are important to day-to-day temporal and spatial characteristics of work patterns (and hence to day-to-day activity–travel schedules) are identified. The four dimensions are full-time versus part-time employment, teleworking or not, inflexible or flexible work schedules, and regular or alternate shifts. This paper develops a comprehensive taxonomy of work arrangements in each of these four dimensions and empirically analyses the factors affecting the work arrangement decisions along three of these dimensions.
