The Government of India on 21 November 2025 notified the coming into force of the four Labour Codes — the Code on Wages, 2019; the Industrial Relations Code, 2020; the Code on Social Security, 2020; and the Occupational Safety, Health and Working Conditions Code, 2020 — rationalising 29 existing Central labour laws. According to the Ministry of Labour and Employment release posted by PIB Delhi at 3:00 PM, the reform is the largest overhaul of India's labour legal framework since the 1930s-1950s statutes and operationalises the principle of Aatmanirbhar Bharat for workers and enterprises alike. Key changes include mandatory appointment letters for every worker to ensure transparency and job security; statutory minimum wages extended to all workers across all sectors; extension of social security coverage under the Code on Social Security to gig and platform workers including Aadhaar-linked Universal Account Numbers; mandatory free annual health check-ups for workers above 40 years; and permission for women to work at night and in all occupations subject to consent and safety measures. Fixed-Term Employees gain gratuity eligibility after one year of service instead of five. Aggregators must contribute 1 to 2 percent of annual turnover, capped at 5 percent of amounts paid to gig and platform workers, funding welfare benefits. ESIC coverage is now pan-India and made mandatory for establishments with even one employee in hazardous processes. Compliance is simplified with a single registration, single pan-India licence and single return replacing multi-statute obligations, lowering the compliance burden on industry.
