Underemployment - when people are employed in some way that is insufficient, such as being overqualified or working part-time when one desires full-time employment - is a challenge faced by all industrialized nations and their organizations and individuals. Just like unemployment, some level of underemployment exists even in the best of times, but it becomes more pervasive when the job market is weak. Given the current economic climate in North America and abroad, researchers and scholars in various disciplines (psychology, business, sociology, economics) are becoming more interested in investigating the effects of underemployment and identifying possible practical solutions. Underemployment synthesizes the current understanding of the phenomenon by bringing together scholars with diverse perspectives and expertise with the aim of informing and guiding the next generation of underemployment research.
