The Four Labour Codes (2019–2020)

“The history of labour legislation is the history of the gradual replacement of the law of master and servant by the law of employer and employee.”

Between 2019 and 2020, Parliament consolidated 29 central labour laws into four Labour Codes — the biggest labour-law reform since independence, on the recommendation of the Second National Commission on Labour (2002), chaired by Ravindra Varma.

Key shift: from master–servant (employer commands, worker obeys) to employer–employee (both governed by statute). The worker is no longer a mere contracting party — he has a defined legal status.

For Labour Law I, only two Codes matter: the IR Code 2020 (industrial disputes, trade unions, standing orders) and the Code on Wages 2019 (wages, bonus, equal pay).

The Tripartite Framework & Constitutional Basis

Industrial relations rest on a tripartite framework — Government (makes law, sets standards, adjudicates), Employers (manage, negotiate, pay), and Workers/Trade Unions (bargain, seek redress, strike) — mirroring the ILO model of government + employers + workers at every table.

Labour is a Concurrent subject (Schedule VII) — both Centre and States can legislate; where they conflict, the Central law prevails (Art. 254).
