In recent years, there has been a growing use in Marxist and
Anarchist theory of the concept of "the precariate," to describe a
growing reliance on temporary, part-time workers with precarious status,
who share aspects of the proletariat and the reserve army of labor.
Although non-employed people who are unable or uninterested in
performing legal paid work are not considered among the "unemployed,"
the concept of conjunctural unemployment is used in economics today (now
called "frictional unemployment"). Although Marx's work was earlier, there is no stated link between it and similar modern study.
