Question

​__________ refers to the division of the economy into two areas of employment: a primary sector or upper tier, composed of higher-paid (usually dominant-group) workers in more secure jobs, and a secondary sector or lower tier, composed of lower-paid (often subordinate-group) workers in jobs with little security and hazardous working conditions.

Answer 1

The answer is Split Labor Market Theory. This was proposed by humanist Edna Bonacich in the mid 1970s as an endeavor to clarify racial/ethnic strains and work showcase division by race/ethnicity as far as social structure and political power as opposed to singular level preference.
