Variables Opportunities for job choice in terms of skill demands, job allocation processes, differences between and within firms, and the extent to which jobs provide alternative rewards or are hierarchically structured; whether there are stable differences between workers, providing criteria for the employers to satisfy the labour force; whether workers have the knowledge and relatively stable preferences needed to exercise any control. The last raises questions of orientations to work, and their relation to background factors, as well as their relevance for job choice. The data consist of two surveys of jobs and workers performing them. In addition, background information on town, firms, unions, etc. was obtained from key interviews, observation, newspaper reports and so on.
