Contract Labour Under the OSH Code: Principal Employer Licence, Welfare and Wage Evidence

By Ravi Sisodia · Reviewed by CA Divyanshu Sengar · Updated 5 October 2026

Principal employers need a contractor-by-contractor evidence chain covering coverage/licence, attendance, wages, welfare and site safety; a vendor invoice alone does not prove labour-code compliance.

Finin2min 2-Minute Summary

• The OSH Code consolidates the central contract-labour framework and allocates obligations between contractor and principal employer.
• Coverage and licensing should be checked against the live Code/Rules and the actual worker count, not an old CLRA certificate copied forward.
• Principal employers should obtain member-level wage and attendance evidence, not only contractor declarations.
• Welfare and site-safety duties can remain relevant even when payroll is run by the contractor.
• Contract closure should include final wage/benefit reconciliation before security deposit or last invoice is released.

Start with the real workforce, not the purchase order

For each contractor, record nature of work, worksite, contract period, peak workers, worker category, home state where relevant, licence/registration status and subcontractors. Procurement's vendor master is not enough because the labour-code test follows the people and work actually deployed.

Use gate/attendance data to cross-check the contractor's reported headcount. Repeated mismatches are a compliance signal even if invoices are commercially correct.

Principal-employer monitoring needs employee-level proof

Obtain wage sheets, bank-payment proof, attendance, overtime, statutory contribution evidence and prescribed welfare/safety records. Sample worker acknowledgements or bank credits rather than relying solely on a signed monthly declaration.

If a contractor defaults, the principal employer should follow the statutory responsibility framework and contract recovery mechanism rather than allowing workers to remain unpaid while the parties argue.

Welfare and safety are site controls

Induction, PPE, medical/safety training, access control, canteen/restroom/first-aid and accident reporting should include contract workers within the applicable thresholds and rules. The fact that a worker is on another entity's payroll does not remove site risk.

Keep incident records linked to contractor and worker ID so safety lessons feed back into vendor evaluation.

Common failure mode: compliant contractor, non-compliant subcontractor

A principal contractor can produce complete wage and contribution records while quietly using a subcontractor whose workers are missing from the approved roster. The principal employer should therefore require disclosure of subcontracting, compare gate/access data with the contractor hierarchy and prohibit unapproved labour substitution where the contract or law requires control.

Monthly compliance certificates are most useful when backed by samples. Pick workers from the site-access list rather than from the contractor's own wage sheet, then trace attendance, bank payment, overtime and statutory contribution. This reverse sample is more likely to find omitted workers.

At contract closure, obtain a final worker-dues statement and preserve enough contact information to investigate later wage or benefit claims. Releasing the last commercial payment before closing labour exceptions reduces the principal employer's leverage.

• Include subcontractor approval in vendor governance.
• Sample from independent site-access data.
• Hold unresolved worker dues in the contract-close checklist.
• Link safety incidents to the responsible contractor tier.

Principal-employer file

• Contractor and licence/registration status.
• Worker roster and attendance reconciliation.
• Wage, overtime and bank-payment evidence.
• PF/ESI/social-security evidence where applicable.
• Site induction, PPE and welfare records.
• Incident/grievance register.
• Final dues confirmation before contract closure.

Questions readers commonly ask

Is a contractor invoice enough evidence?

No. Labour compliance should be supported by worker-level attendance, wage and statutory evidence.

Does the principal employer have no responsibility if the contractor defaults?

No. The Code contains principal-employer responsibilities; facts and current Rules must be checked.

Should subcontractors be included?

Yes, where used; the principal employer needs visibility through the labour supply chain.

What is the best monthly control?

Reconcile site attendance to contractor wage and bank-payment records.
