Full employmentFull employment is a situation in which there is no cyclical or deficient-demand unemployment. Full employment does not entail the disappearance of all unemployment, as other kinds of unemployment, namely structural and frictional, may remain. For instance, workers who are "between jobs" for short periods of time as they search for better employment are not counted against full employment, as such unemployment is frictional rather than cyclical.
Frictional unemploymentFrictional unemployment is a form of unemployment reflecting the gap between someone voluntarily leaving a job and finding another. As such, it is sometimes called search unemployment, though it also includes gaps in employment when transferring from one job to another. Frictional unemployment is one of the three broad categories of unemployment, the others being structural unemployment and cyclical unemployment.
