Like unemployment, the level of employment also moves in a cyclical way. There is not, however, an exact negative relationship between the level of unemployment and the level of employment. It is possible that when a job is filled (and therefore the level of employment goes up) that it is taken by someone who is not counted as unemployed (and there will not therefore be a corresponding drop in unemployment). This could either be because they are not included in the definition of unemployment or perhaps because they are already employed. In spring 1999, there were 1.3 million people in the UK with more than one job. Figure 13.1 shows what has happened to the level of employment in the UK over the period 1987–2003.
