Secondary labor market
The secondary labor market is the labor market consisting of high-turnover, low-pay, and usually part-time or temporary work. 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.<ref name=bew>Template:Cite journal</ref>
Secondary market jobs are sometimes referred to as "food and filth" jobs, a reference to workers in fast food, retail, or yard work, for example.<ref name=bbi>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
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 "breadwinner" in order to supplement family income.
