Principal employer liability means that when a contractor supplies workers to your establishment and fails to pay them, the law makes you answerable. Under the OSH Code, the principal employer must pay the unpaid or short wages in full and then recover that money from the contractor.

Where the liability sits

The “principal employer” is the owner or occupier of the factory, the owner or agent of a mine, or whoever is responsible for supervision and control of any other establishment. The contract labour provisions of the Code, which replaced the Contract Labour (Regulation and Abolition) Act, bite where an establishment has 50 or more contract workers, or a contractor has employed that many. The main exposures are:

• Wages (section 55): the contractor must pay by bank transfer or electronic mode and tell you electronically what was paid. If wages are late or short, you pay and recover by deducting from the contractor’s bills or as a debt. The Central Rules are reported to set a seven-day payment window for the contractor and 15 days for you to step in.
• Welfare (section 53): the health, safety and welfare facilities the Code requires, such as drinking water, latrines and the other items prescribed, must be provided to contract workers by you, not the contractor.
• Unlicensed contractor (section 54): using a contractor who needs a licence but has none is itself a contravention, by you.
• Core activities (section 57): contract labour is prohibited in core activities, with exceptions for work normally done through contractors, work that does not need full-time hands, and sudden spikes. Sanitation, security, canteen and loading are listed as non-core support services, unless the establishment is set up for that very activity.

Social security follows the same pattern. The Code on Social Security is summarised by law firms as making the principal employer answerable for PF and ESI contributions on contract workers, with a right to recover them from the contractor.

A worked example

A contractor supplies 60 workers at Rs 18,000 a month and skips a month. The unpaid wage bill is 60 x Rs 18,000 = Rs 10,80,000. The licence security is reported at Rs 1,000 per worker, which is Rs 60,000 here, so that deposit covers only about 5.6 per cent of the gap. Most of the exposure lands on your books until you recover it. Compare the real cost first with the contractor vs employee cost analysis.

Frequently asked questions

How do I protect myself before paying a contractor invoice?

Ask for proof of wage transfer and the latest ECR and ESI challans, and withhold the part of the bill that the proof does not cover. The right to deduct is written into the Code.

Does it apply to gig or platform workers?

No. This is about contract labour supplied through a contractor; gig staffing and platform workers sit under a different framework.

Do the thresholds apply the same way in every state?

The Code says 50, but state rules are still being finalised, so confirm with your state before treating a 30-worker contract force as outside the regime.
