Frictional unemployment occurs when - WAEC Economics 2015 Question

Frictional unemployment is a type of unemployment that arises when workers are searching for new jobs or are transitioning from one job to another

Frictional unemployment refers to people who are simply moving from one job to another, but are taking their time. It is part of the jobless total caused by individuals who are spending time searching for another job, or perhaps are taking a break before beginning with a new employer. Even in a country where there is technically full employment, there will always be some frictional employment, simply because employees change jobs occasionally.
