43  The Contract Labour (Regulation and Abolition) Act 1970: Object, Definitions, Advisory Boards, Registration of Principal Employer, Licensing of Contractor, Welfare Provisions, Section 10 Prohibition, Steel Authority Judgment and the OSH&WC Code 2020

43.1 Why Contract Labour Needs a Statute

A contract worker is engaged not by the principal employer but by an intermediary contractor who supplies the workforce. The arrangement gives the principal employer flexibility — it can scale up and down quickly, focus on its core competence and avoid permanent payroll commitments. But it also creates a structural risk: the worker has no direct line to the establishment whose work he performs, and the contractor may keep wages, deny welfare facilities or vanish. The Contract Labour (Regulation and Abolition) Act 1970 tries to balance the legitimate use of contract labour with worker protection — by regulating contract employment where it is legitimate and abolishing it where the work is perennial in nature.

43.2 1 · Historical Background

Three developments led to the 1970 Act.

43.2.1 Two Pre-1970 Supreme Court Decisions

In Standard Vacuum Refining Co. v. Their Workmen (1960), the Supreme Court held that a tribunal could direct the abolition of contract labour where the work was of a perennial nature and could be performed by regular workmen. In Gammon India Ltd. v. Union of India (1974) (decided after the Act but invoking pre-Act principles), the Court re-affirmed the validity of the regulatory framework.

43.2.2 Recommendations of the First National Commission on Labour (1969)

The First NCL (Gajendragadkar Commission, 1969) noted that contract labour was widespread in industries such as construction, mining, oil refining, ports and ship-breaking — and that contract workers were paid less than directly-employed workmen for the same work and received no welfare. The Commission recommended both regulation of contract labour in tasks of a temporary or sporadic character and abolition in tasks that were perennial and essential to the establishment.

43.2.3 Three Driving Concerns

TipThree Concerns the Act Addressed
Concern Description
Substitution for direct employment Contract labour was being used to avoid the protective regime of the ID Act 1947 and the Factories Act 1948
Wage and welfare disparity Contract workers received lower wages and fewer benefits than directly-employed workers performing the same tasks
No accountability Workers could not identify a responsible employer when grievances arose

43.3 2 · Object, Extent and Commencement

TipObject and Scope
Aspect Detail
Year 1970 (Act 37 of 1970)
Commencement 10 February 1971
Object To regulate the employment of contract labour in certain establishments and to provide for its abolition in certain circumstances
Extent The whole of India
Successor OSH&WC Code 2020

43.4 3 · Applicability and Thresholds — Section 1

TipApplicability
Provision Threshold
Every establishment in which 20 or more workmen are employed (or were employed on any day of the preceding 12 months) as contract labour Applies
Every contractor who employs (or has employed) 20 or more workmen on any day of the preceding 12 months Applies
Establishments in which work of an intermittent or casual nature is performed May be exempt
OSH&WC Code 2020 — threshold raised to 50 New threshold
NotePYQ trap — 20 raised to 50 under OSH&WC Code

The original threshold of 20 contract workers is raised to 50 under the OSH&WC Code 2020 — leaving smaller establishments outside the regulatory regime. NTA stems frequently pair the two thresholds.

43.4.1 Work of Intermittent or Casual Nature

Work is treated as intermittent if it was performed for fewer than 120 days in the preceding 12 months. It is casual if it was performed only for a particular function or occasion. Both categories receive lighter regulation.

43.5 4 · Key Definitions — Section 2

TipSection 2 — Important Definitions
Term Section Substance
Contract labour 2(b) A workman is deemed to be employed as contract labour when he is hired in or in connection with the work of an establishment by or through a contractor — with or without the knowledge of the principal employer
Contractor 2(c) A person who undertakes to produce a given result for the establishment, other than by mere supply of goods or articles of manufacture, through contract labour; includes a sub-contractor
Principal employer 2(g) In a government department — the head of the department; in a factory — the owner / occupier / manager; in a mine — the owner / agent / manager; in any other establishment — the person responsible for supervision and control
Establishment 2(e) Any office or department of the government or a local authority; any place where any industry, trade, business, manufacture or occupation is carried on
Workman 2(i) Any person employed in or in connection with the work of an establishment to do skilled, semi-skilled, unskilled, manual, supervisory, technical or clerical work — with prescribed exclusions
Wages 2(h) As defined in the Payment of Wages Act 1936

43.6 5 · Advisory Boards — Sections 3 to 5

The Act establishes a tripartite advisory framework at two levels.

TipCentral and State Advisory Boards
Body Section Composition Function
Central Advisory Contract Labour Board 3 Chairman + members representing central government, railways, employers, workmen, others (not exceeding 17) Advise the central government on matters arising out of the Act
State Advisory Contract Labour Boards 4 Chairman + members representing the state government, employers, workmen, others (not exceeding 11) Advise the state government on matters arising out of the Act
Power to constitute committees 5 Both Boards may constitute sub-committees for specific issues Detailed examination

43.7 6 · Registration of Principal Employer — Sections 6 to 11

TipRegistration of Establishments
Section Provision
6 Registering Officer appointed by the appropriate government
7 Application for registration by the principal employer within prescribed time
8 Conditions for grant of certificate of registration
9 Effect of non-registration — establishment cannot employ contract labour through any contractor
10 Power to prohibit employment of contract labour in any process / operation / work in any establishment — see Section 7 below
11 Revocation of certificate of registration

43.7.1 Section 10 — Power to Prohibit Contract Labour

This is the most powerful provision in the Act and the gateway to abolition. Under Section 10:

TipSection 10 — Five Factors for Prohibition
Factor Description
1 Whether the process, operation or other work is incidental or necessary for the industry / trade / business / manufacture / occupation that is carried on in the establishment
2 Whether it is of perennial nature — that is, of sufficient duration
3 Whether it is done ordinarily through regular workmen in that establishment or an establishment of a similar kind
4 Whether it is sufficient to employ a considerable number of whole-time workmen
5 The conditions of work and benefits provided for the contract labour

The appropriate government may, after consultation with the Central or State Advisory Board, by notification, prohibit employment of contract labour in any such work. The decision turns on the perennial vs sporadic distinction.

43.8 7 · Licensing of Contractors — Sections 12 to 15

TipLicensing of Contractors
Section Provision
12 Licence required — no contractor shall undertake or execute any work through contract labour except under and in accordance with a licence
13 Conditions of grant of licence — fees, hours of work, fixation of wages, payment of wages, holidays, payment of welfare amenities, etc.
14 Revocation, suspension and amendment of licence
15 Appeal — against an order of the Registering Officer or Licensing Officer

43.9 8 · Welfare and Health Provisions — Sections 16 to 19

The Act prescribes specific welfare obligations for contractors, with fallback liability on the principal employer.

TipWelfare Provisions
Section Provision Trigger
16 Canteen Establishment with 100 or more contract workers working for 6+ months; canteen for each work site as prescribed
17 Rest rooms Where contract labour is required to halt at night
18 Other welfare facilities — drinking water, latrines, urinals, washing facilities, first-aid All establishments
19 First-aid facilities — first-aid box for every prescribed group
TipContract Labour Welfare Mnemonic

Drinking water + Latrines + Washing + First-aid for all · Canteen at 100+ · Rest rooms if night halt

43.10 9 · Wages, Payment and Liability — Sections 20 to 21

TipWages and Liability
Section Provision
20 Liability of principal employer in certain cases — where amenities under Sections 16-19 are not provided by the contractor, the principal employer must provide them and may recover the cost from the contractor
21 Responsibility for payment of wages — contractor primarily responsible; if contractor fails, principal employer is liable to pay the wages or unpaid balance, with right of recovery from contractor as a debt

43.10.1 Disbursement and Inspection

The contractor must disburse wages in the presence of a nominee of the principal employer, who must certify the amounts paid. This dual oversight is intended to prevent under-payment.

43.11 10 · Inspectors, Registers and Records — Sections 28 to 30

TipInspection Machinery
Section Provision
28 Inspectors appointed by the appropriate government — powers of entry, examination, sampling, seizure
29 Registers and records to be maintained by principal employer and contractor — register of contractors, register of contract labour, wage registers, etc.
30 Effect of laws and agreements inconsistent with the Act — Act prevails

43.12 11 · Penalties — Sections 22 to 27

TipPenalties under the 1970 Act
Section Offence Punishment
22 Obstruction of inspector Up to 3 months / Rs 500 or both
23 Contravention of provisions about employment of contract labour Up to 3 months / Rs 1,000 or both
24 Other offences Up to 3 months / Rs 1,000 or both
25 Offence by company Persons in charge liable
26 Cognisance On complaint by inspector or with previous sanction
27 Limitation of prosecutions Three months from date of offence

43.13 12 · Landmark Judicial Decisions

43.13.1 Air India Statutory Corporation v. United Labour Union (1997)

The Supreme Court — in a sharply contested judgment — held that on prohibition of contract labour under Section 10, contract workers become automatically absorbed as regular employees of the principal employer. The decision sent shockwaves through industries that relied on contract workers and was severely criticised as encouraging litigation.

43.13.2 Steel Authority of India Ltd. v. National Union Waterfront Workers (2001) — Constitution Bench

A five-judge Constitution Bench of the Supreme Court overruled the Air India position. The Court held:

  • A notification under Section 10 prohibits the employment of contract labour in the specified work but does not automatically make contract workers regular employees of the principal employer.
  • Whether contract workers should be absorbed is a separate question that may be raised before an industrial tribunal under the ID Act 1947.
  • The sham or camouflage test applies: where the contract is a mere device and the workers are in reality directly employed by the principal employer, they may be declared direct employees from the outset; if the contract is genuine, prohibition merely stops the contracting arrangement.
NotePYQ anchor — Steel Authority overrules Air India

Steel Authority of India v. National Union Waterfront Workers (2001) is the leading case on contract-labour absorption. It overruled the Air India (1997) decision and held that prohibition under Section 10 does not automatically result in regularisation of contract workers; absorption is a separate question for the tribunal.

43.13.3 Gammon India Ltd. v. Union of India (1974)

The Supreme Court upheld the constitutional validity of the Act against challenges under Articles 14 and 19. The Court accepted the legislative discretion to regulate or abolish contract labour as a reasonable restriction in the public interest.

43.13.4 Other Relevant Cases

  • R.K. Panda v. Steel Authority of India (1994) — contract labourers continuously engaged for years can claim regularisation in appropriate cases.
  • National Aluminium Co. Ltd. v. Workmen (2003) — sham contract test reaffirmed.

43.14 13 · Position under the OSH&WC Code 2020

The OSH&WC Code 2020 subsumes the 1970 Act with significant changes.

TipContract Labour Act 1970 vs OSH&WC Code 2020
Provision 1970 Act OSH&WC Code 2020
Threshold 20+ contract workers 50+ contract workers
Registration of principal employer Required Continued; simpler online process
Licensing of contractor Per establishment Single nationwide license for contractors operating across states
Section 10 — prohibition power Retained Continued; criteria broadly preserved
Core / non-core activities Not distinguished Distinguishes “core” activities from “non-core”; contract labour generally prohibited in core activities
Welfare obligations Contractor with fallback on principal employer Continued
Wages liability Principal employer if contractor defaults Continued
Penalties Modest Substantially enhanced

43.14.1 Core vs Non-Core Activities

The Code provides a list of non-core activities (e.g., security, canteen, sanitation, gardening, courier) where contract labour can be engaged. Core activities — those that form the principal or central function of the establishment — generally cannot use contract labour.

43.15 14 · Significance and Critique

  • First comprehensive Indian statute on contract labour.
  • Created a dual trackregulation where contract labour is legitimate, abolition where the work is perennial.
  • Established the principle of principal-employer accountability for wage default and welfare.
  • The Steel Authority case (2001) clarified that prohibition is not automatic regularisation — preserving the regulatory structure but limiting its compulsory consequences.
  • Critique: implementation has been weak; many contractors operate without licence; contract workers continue to receive lower wages; “perennial-vs-sporadic” debates dominate litigation. The OSH&WC Code 2020 raises the threshold to 50 — narrowing the regime.
