The Contract Labour (Regulation and Abolition) Act 1970 (CLRA) regulates the employment of contract labour in certain establishments and provides for its abolition in certain circumstances. It governs the relationship between principal employers (clients), contractors (suppliers), and contract workmen.

Applicability

The CLRA applies to:

  • Every establishment employing 20 or more contract workmen (directly or through contractor)
  • Every contractor employing 20 or more workmen

The appropriate government can extend the Act to establishments with fewer workers. Agricultural work, seasonal and intermittent works may be exempted by government notification.

Registration of Principal Employer

Every principal employer must obtain registration from the Registering Officer (usually Labour Commissioner):

  • Application in Form I (within 30 days of engagement of contract labour)
  • Certificate of Registration in Form II issued
  • Cannot engage contractor without registration
  • Principal employer = person having ultimate control of establishment

Licensing of Contractors

Every contractor employing 20 or more contract workmen must obtain a licence from the Licensing Officer:

  • Application in Form IV
  • Licence granted in Form V
  • Licence specifies number of workmen, type of work, fees paid
  • Security deposit of Rs.10-50 per workman depending on state
  • Annual renewal required

Principal Employer Liability for Wages and Welfare

Key obligations of principal employer under CLRA:

Section 20: Liability for Welfare Facilities

If a contractor fails to provide welfare facilities required under the Act (canteen, rest rooms, first aid), the principal employer must provide them and can recover costs from the contractor.

Section 21: Liability for Wages

If contractor fails to pay wages or deducts unauthorized amounts:

  • Principal employer is liable to ensure wages are paid
  • Principal employer can pay and recover from contractor's security deposit or dues
  • This is one of the most important provisions — PE has vicarious liability for wage payment

Welfare Facilities Required by Contractor

FacilityThreshold
First-Aid boxAll contractors
Canteen100+ contract workers at one place
Rest roomsWork near or away from home for continuous period
Drinking waterAll contractors
Latrines and urinalsAll; separate for male and female

Abolition of Contract Labour

Section 10 empowers the appropriate government to prohibit employment of contract labour in certain processes if:

  • The work is perennial in nature
  • The work is ordinarily done by regular employees
  • The work is incidental/necessary for the industry
  • The work is sufficient to employ considerable number of full-time workmen

Landmark Case: Steel Authority of India Ltd. v. National Union (2001 SC) — Abolition of contract labour does not automatically mean absorption by principal employer unless government order specifically says so.

Social Security for Contract Workers

Contract workers are entitled to:

  • EPF and ESI coverage (contractor must deduct and deposit)
  • Minimum wages under Minimum Wages Act
  • Gratuity under Payment of Gratuity Act
  • Benefits under Workmen's Compensation Act (now Employee Compensation Act 2009)

Principal employer must ensure contractor compliance with these social security laws. If contractor defaults, principal employer faces liability.

Code on Occupational Safety, Health and Working Conditions 2020

The OSH Code 2020 subsumes the Contract Labour Act 1970, Factories Act 1948, and 11 other central laws. When implemented, it raises the contract labour threshold to 50 workmen (from 20) for applicability. Licensing and registration requirements continue in modified form.

Practical Compliance Tip: Principal employers must maintain Form XII (Register of Contract Labour) at the establishment showing all contractors, number of workmen, work done, and dates. Regular audits of contractor compliance documents (Form XIII - contractor's register, EPF/ESI challans, wage registers) should be conducted to mitigate vicarious liability.

Frequently Asked Questions
What is the threshold for applying Contract Labour Act?
The Contract Labour Act 1970 applies to establishments employing 20 or more contract workmen and to contractors employing 20 or more workmen. The Code on Occupational Safety Health and Working Conditions 2020, when implemented, will raise this to 50 workmen.
Is the principal employer liable for non-payment of wages by contractor?
Yes, under Section 21 of the Contract Labour Act, if a contractor fails to pay wages within the prescribed time, the principal employer must ensure wages are paid. The principal employer can then recover the amount paid from the contractor's security deposit or outstanding dues.
Does abolition of contract labour mean automatic absorption by principal employer?
No. The Supreme Court in Steel Authority of India Ltd. v. National Union (2001) held that abolition of contract labour under Section 10 does not automatically confer regular employment status on contract workers. The government order must specifically provide for absorption, which is rare.
What licence does a contractor need under Contract Labour Act?
A contractor employing 20 or more workmen must obtain a licence from the Licensing Officer under the state where work is to be done. The licence in Form V specifies the maximum number of workmen, nature of work, and other conditions. Annual renewal is required.
Are contract workers entitled to EPF and ESI?
Yes, contract workers are entitled to EPF (if establishment employs 20+ workers) and ESI (if in covered area and wages below Rs.21,000/month). The contractor is primarily responsible for enrolling and contributing; the principal employer has liability if the contractor defaults.
What records must be maintained under Contract Labour Act?
Principal employers must maintain Form XII (Register of Contractors). Contractors must maintain Form XIII (Register of Contract Labour), Form XIV (Employment Card), Form XV (Service Certificate), wage register, and muster roll. These registers must be available for inspection by labour inspectors.
