The secondary labor market is the labor market consisting of high-turnover, low-pay, and usually part time and/or temporary jobs. Sometimes, secondary jobs are performed by high school or college students. The majority of service sector, light manufacturing, and retail jobs are considered secondary labor. A secondary-market job is distinct from a "secondary worker". The latter term refers to someone in a family (traditionally, the wife or a child) who earns a smaller income than the "bread-winner" in order to supplement the family income.
