The Government of India has consolidated and amalgamated 29 central labour laws into 4 comprehensive Labour Codes. This move aims to simplify the complex compliance landscape, modernise outdated provisions, and extend social security to all workers (including gig and platform workers).
Below is the complete list of the 29 old laws and how they have been merged into the new system.
1. The Code on Wages, 2019
Focus: Regulating wage rates, bonus payments, and equal remuneration.
Old Laws Subsumed (4 Acts):
The Minimum Wages Act, 1948: Governed minimum wage rates.
The Payment of Wages Act, 1936: Ensured timely payment without unauthorized deductions.
The Payment of Bonus Act, 1965: Mandated annual bonus for employees in certain profit/production scenarios.
The Equal Remuneration Act, 1976: Prohibited gender discrimination in payment.
How it Merges & Changes:
Universal Applicability: Unlike the old laws which applied to specific “scheduled” employments, the new Code applies to all employees across all sectors.
Floor Wage: The Central Government will fix a “Floor Wage.” State governments cannot fix minimum wages below this floor.
Unified Definition: A single definition of “Wages” is introduced to reduce litigation and confusion (generally: Basic + DA + Retaining Allowance).
2. The Industrial Relations (IR) Code, 2020
Focus: Trade unions, strikes, lockouts, layoffs, and retrenchment.
Old Laws Subsumed (3 Acts):
The Trade Unions Act, 1926: Registered and protected trade unions.
The Industrial Employment (Standing Orders) Act, 1946: Required employers to define conditions of employment (standing orders).
The Industrial Disputes Act, 1947: Governed layoffs, retrenchment, and dispute resolution.
How it Merges & Changes:
Increased Thresholds: The requirement to have certified “Standing Orders” now applies only to establishments with 300 or more workers (previously 100).
Fixed Term Employment: Formally introduces “Fixed Term Employment,” allowing employers to hire contract workers for a specific duration with full statutory benefits (like pro-rata gratuity), reducing reliance on contractors.
Sole Negotiating Union: If there are multiple unions, the one with 51% or more workers as members will be recognized as the sole negotiating agent.
3. The Code on Social Security, 2020
Focus: Social security benefits like PF, ESI, gratuity, and maternity coverage.

The Maternity Benefit Act, 1961: Paid leave for women during maternity.
The Employees’ Compensation Act, 1923: Compensation for workplace injuries.

Digitisation: Mandates Aadhaar-based registration for all unorganised workers on a national portal (e-Shram).
Gratuity: Fixed-term employees are now eligible for gratuity on a pro-rata basis, even if they work for less than 5 years.
4. The Occupational Safety, Health and Working Conditions (OSH) Code, 2020
