The preceding chapters have identified two principal aspects of happiness. The first is subjective well-being, which may be measured on three axes of experience: from feeling bad to feeling good, from anxiety to comfort, and from depression to enthusiasm (see Fig. 2.2 on p. 22). Assessments tend to be either more affective, particularly emphasizing current feelings, or more reflective, drawing on recollections and interpretations to generate reports of satisfaction or similar constructs. Experiences of happiness also differ in their scope, with context-free happiness concerning life in general and domain-specific happiness focused on a particular area, such as one’s family, job, health or self. As described earlier, single domains can themselves be subdivided, so that attention might be directed at separate facets of, say, a job or one’s family life. This chapter and the following three are concerned with the characteristics of jobs, and mainly emphasize jobrelated (domain-specific) happiness and forms of facet-specific happiness within the job domain.
