The term “underemployment” has three related meanings. In one sense, it refers to a situation in which someone with excellent job qualifications (资格) is working in a position that requires less qualifications, as for instance in the case of a lawyer driving a school bus. In the second sense, it means working part-time when one would prefer to be working full-time. In the third sense, it is a form of overstaffing (人浮于事) in which employees are not being fully made use of.
All forms of underemployment have effect on the economy and the health of the business community. Long-term underemployment can also cover up the truth behind the employment situations. When nations collect employment statistics, they usually come up with a base number of “unemployed” individuals, using that number to judge the health of the job market. This number does not include part-time workers looking for full-time jobs, as they are considered employed, and it also doesn’t reflect workers who are underpaid, considering their qualifications.
