OSH Code 2020: Working Hours, Licences, Appointment Letters

In forceCentral Rules 8 May 2026

The Occupational Safety, Health and Working Conditions Code, 2020 consolidates thirteen laws on factories, contract labour, mines, migrant workers and building workers into one code. For manpower and staffing firms the most important point is that the Contract Labour Act now sits inside this code, so contract-labour licensing and registers are governed here. It also makes an appointment letter mandatory for every worker and sets the daily and weekly hours limit with overtime at twice the ordinary rate.

Contract labour and licensing

Contract-labour regulation moves into the OSH Code. A contractor generally needs a licence and the principal employer a registration where the threshold is met, and the prescribed registers must be maintained. Because ZeniaHR is built for manpower and staffing firms, this is the code that governs the day-to-day contract-labour compliance those firms run.

Health, safety and welfare

The code requires annual free health check-ups for prescribed classes of worker, safety committees at larger establishments, and welfare facilities. Duties scale with establishment size and hazard.

Frequently asked questions

Is the Contract Labour Act still separate, or part of the OSH Code?

The Contract Labour (Regulation and Abolition) Act is now subsumed into the OSH Code, so contract-labour licensing, registers and principal-employer duties are governed under this code.

What are the working-hours limits under the OSH Code?

The code sets a limit of up to 8 hours a day and 48 hours a week, with overtime paid at twice the ordinary rate. The precise overtime accounting is set in the OSH (Central) Rules 2026.

Is an appointment letter mandatory now?

Yes. The OSH Code makes it mandatory for every employer to issue an appointment letter to each employee.

Which laws did the OSH Code replace?

Thirteen, including the Factories Act 1948, the Contract Labour Act 1970, the Inter-State Migrant Workmen Act 1979, the BOCW Act 1996 and the Mines Act.
