Labour market segmentation is the condition in which a labour market operates not as one competitive arena but as a set of walled compartments. Workers of similar skill receive different rewards depending on the segment they occupy, and movement between segments is restricted rather than free. The idea directly contradicts the neoclassical picture of a single market clearing at one wage, and replaces it with a sociological account in which institutions, employer strategies and social identity allocate people to positions.
Where it comes from
Doeringer and Piore's work on internal labour markets distinguished a primary sector — stable employment, career ladders, formal rules, union protection, investment in training — from a secondary sector of unstable, low-paid jobs with high turnover, arbitrary supervision and no advancement. Employers create the primary segment where they need to retain firm-specific skills, and use the secondary segment to absorb fluctuations in demand. Because primary jobs are rationed, entry depends less on productivity than on the queue at the gate — and the queue is ordered by criteria that are social.
How it works in India
In India the segmenting devices are caste, gender, religion and migrant status. Recruitment runs through kin and caste networks, so occupational niches are inherited rather than competed for; Harriss-White documents how community and gender structure access to work and credit alike. Manual and stigmatised work remains concentrated among Dalit workers. Women are channelled into home-based, piece-rated and care work with wage gaps that persist after controlling for schooling. Circulating migrants — Breman's footloose labour — enter as a distinct segment recruited through contractors, paid through advances, and excluded from whatever protection local workers enjoy. Formal-informal duality is thus overlaid by segmentation within the informal economy itself.
For the UPSC answer
Define segmentation against the single-market assumption, use the primary-secondary distinction from Doeringer and Piore, and then argue that in India ascriptive identity performs the sorting. The strong move is to show that segmentation explains why growth does not translate into mobility: the barrier is not skill but the boundary of the segment.
