Essential vocabulary

Key concepts to remember

Formal employmentWork covered by recognised rules and protections such as written contracts or social security; coverage is uneven.
Informal workWork with limited regulation, security or social protection; informality can occur in enterprises and in employment relations.
Home-based workProduction carried out in or around a home, often linked to wider markets through contractors or supply chains.
Trade unionAn organisation through which workers collectively represent interests and negotiate over pay, conditions and rights.

Core idea

From planned industry to liberalisation

After Independence, India pursued planned industrialisation with a substantial public sector, regulation and goals of building domestic productive capacity. Policies also supported small-scale industry. Since 1991, liberalisation reduced or changed some controls and expanded the role of markets and private investment. The transition was uneven across sectors and workers.

Industrial development changes the scale and location of production, but does not distribute gains automatically. Ask who owns assets, who controls work, what skills are required and how public policy shapes employment. Liberalisation can expand markets and investment while also intensifying competition and insecurity for some producers and workers.

Core idea

How people find jobs and how work is organised

People find jobs through formal advertisements, employment services, qualifications, family and community networks, referrals, contractors and digital platforms. These channels are not equally available. Social background can shape access to information, credentials, safe mobility and networks. Recruitment practices therefore connect labour markets to broader social inequality.

Work may be formal or informal, permanent or casual, paid by time or output, supervised in a workplace or subcontracted to a home. A company’s supply chain can hide who sets deadlines and prices. Women’s home-based work may combine paid production with unpaid care, making both the hours and the value of labour difficult to see.

Core idea

Working conditions, unions and collective action

Working conditions include wages, hours, safety, security, leave, dignity and voice in decisions. A job count alone cannot show whether work is decent or whether a worker can refuse unsafe conditions. Labour laws and enforcement matter, but workers’ ability to organise also affects bargaining power.

Strikes temporarily withdraw labour to press a collective demand. Trade unions can negotiate, represent grievances and build solidarity, though workers may face retaliation, fragmentation or barriers to organising. New contract forms and dispersed workforces make collective organisation more difficult, but not impossible. Study both institutional protections and everyday practice.

Apply the concept

Worked example

A home-based worker stitching garments may receive a piece-rate from a contractor, while a brand sets quality and delivery requirements. Mapping each link helps identify who controls the work, who bears delays and whether the worker has access to protections.

Board preparation

Practice questions

  1. Compare formal and informal work using two dimensions beyond workplace location.
  2. Explain how social networks can influence access to jobs.
  3. Discuss why collective organisation matters for working conditions.
How to shape a high-quality response

Define the employment category precisely; show how hiring, control and protection operate; then connect the arrangement to inequality or worker agency. Do not assume that all informal work is identical or that a factory job is automatically secure.

Self-check: Did I define the concept, explain the social process, use relevant evidence or an example, and avoid generalising beyond it?
