Surveys consistently indicate that 80-90 per cent of people are relatively happy at work. However, it is clear that while job satisfaction is generally high, this is not true of all work settings and jobs; nor is it true of all socio-economic and ethnic groups. Given that sociological and organizational factors obviously contribute to job satisfaction, the question must remain as to the personality factors associated with those who claim either to be highly or not at all job satisfied. Consider, for example, the work by Locke (1984) which look at how to increase job satisfaction (see Table 6.1).He identified eight factors of work and appropriate strategies but rarely considered the important moderating role of personality factors. Hence, with few exceptions, the proposed solutions are organizational rather than individual difference focused.
