36  The Industrial Disputes Act 1947: Object, Definitions, Authorities, Reference, Awards, Restrictions on Strikes and Lock-outs, Chapters V-A and V-B, Unfair Labour Practices, and the IR Code 2020

36.1 The Backbone of Indian Industrial-Dispute Law

For more than seventy years, the Industrial Disputes Act 1947 has been the central statute governing investigation and settlement of industrial disputes in India. It defines who is a worker and what is a dispute; sets up conciliation officers, boards, courts and tribunals; lays down rules on lay-off, retrenchment, transfer and closure; restricts strikes and lock-outs; lists unfair labour practices; and imposes penalties. The earlier topics in this chapter examined parts of this scheme in detail; this concluding topic provides a consolidating overview of the Act as a whole, and notes how the Industrial Relations Code 2020 has carried forward, modified or replaced its provisions.

36.2 1 · Object, Extent and Commencement

TipObject and Scope
Aspect Detail
Year of enactment 14 March 1947
Came into force 1 April 1947
Object To make provision for the investigation and settlement of industrial disputes, and for matters connected therewith
Extent The whole of India
Successor statute Industrial Relations Code 2020

The Act was modelled on the British Industrial Courts Act 1919 and the colonial Trade Disputes Act 1929, but expanded with provisions reflecting India’s tripartite tradition and the post-war reconstruction needs.

36.3 2 · Key Definitions — Section 2

36.3.1 The Bangalore Water Supply Test for “Industry”

In the landmark case Bangalore Water Supply & Sewerage Board v. A. Rajappa (1978), a seven-judge bench of the Supreme Court gave the word “industry” the broadest possible interpretation — covering virtually every systematic activity organised for the production or distribution of goods or services through employer-employee cooperation. The triple test:

  • Systematic activity.
  • Organised by cooperation between employer and employee.
  • For the production / distribution of goods or services to satisfy human wants.

The case continues to define the scope of who comes within the Act.

36.4 3 · Authorities under the Act — Sections 3 to 9

The Act establishes a sequence of authorities for prevention, conciliation, fact-finding and adjudication.

TipAuthorities under the ID Act 1947
Authority Section Function
Works Committee 3 Bipartite forum for amity-building in 100+ workmen establishments
Conciliation Officer 4 First formal dispute-settler
Board of Conciliation 5 For complex disputes; chair + equal representatives
Court of Enquiry 6 Fact-finding for the government
Labour Court 7 Adjudicates Schedule II matters
Industrial Tribunal 7A Adjudicates Schedule III matters
National Tribunal 7B Adjudicates national-importance disputes (central government)
Grievance Redressal Committee 9C (added 2010) Bipartite forum for individual grievance — 20+ workmen, 30-day decision

36.5 4 · Reference of Disputes — Section 10

Under Section 10, the appropriate government may, by order in writing, refer an industrial dispute that exists or is apprehended to:

  • A Board of Conciliation for promoting a settlement.
  • A Court of Enquiry for inquiring into any matter connected with or relevant to the dispute.
  • A Labour Court for adjudication of any matter specified in Schedule II.
  • An Industrial Tribunal for adjudication of any matter specified in Schedule II or III.
  • A National Tribunal for adjudication where the dispute is of national importance or affects establishments in more than one state.

The government’s discretion to refer is wide but not unlimited — courts have ruled that it must be exercised reasonably and after considering the dispute’s merits.

36.5.1 Section 10A — Voluntary Arbitration

Parties may, by written agreement signed before reference to any authority, refer the dispute to one or more arbitrators. The agreement and the resulting arbitration award receive statutory recognition and are binding under Section 18.

36.6 5 · Procedure of Authorities — Sections 11 to 16

TipProcedure of Authorities
Section Provision
11 Authorities follow such procedure as they think fit; powers of a civil court for examining witnesses, taking evidence on oath, compelling production of documents
11A Power of labour courts, tribunals and national tribunals to give appropriate relief in cases of discharge or dismissal — including reinstatement even if punishment was not shockingly disproportionate (1971 amendment)
12 Duties of conciliation officers — investigate, mediate, send settlement report within 14 days or failure report
13 Duties of Board of Conciliation — two-month report
14 Duties of Court of Enquiry — report within six months
15 Duties of labour court / tribunal / national tribunal — submit award as soon as practicable
16 Form of report and award — written, signed and copies submitted to the government

36.6.1 Section 11A — A Powerful Tool

Section 11A, inserted in 1971, dramatically expanded judicial review of disciplinary action. A labour court or tribunal can:

  • Set aside the order of discharge or dismissal.
  • Direct reinstatement with full, partial or no back-wages.
  • Substitute a lesser punishment.
  • Re-appraise the evidence and decide the proportionality of punishment.

This converted the labour judiciary from a deferential reviewer into a substantive guardian against arbitrary management action.

36.7 6 · Publication and Operation of Awards — Sections 17 to 19

TipAwards and Settlements — Life-Cycle
Section Provision
17 Award published in the official gazette within 30 days of receipt by the appropriate government
17A Award becomes enforceable on the expiry of 30 days from publication
17B Where a labour court / tribunal orders reinstatement, employer must pay full wages last drawn pending appeal in the High Court / Supreme Court (1982 amendment)
18 Binding effect of settlements and awards
19 Period of operation — usually 1 to 3 years; continues until two months’ notice of termination

36.7.1 Binding Effect — Section 18

TipSection 18 — Binding Effect
Outcome Binding on
Settlement in conciliation Parties to dispute, their representatives, heirs, successors, assigns
Bilateral settlement (outside conciliation) Only the signatories
Adjudication award All parties to the dispute and any party summoned
Arbitration award (Section 10A) Parties to the agreement

36.8 7 · Restrictions on Strikes and Lock-outs — Sections 22 to 25

Already covered in detail in Topic 33. Summary:

  • Section 22 — public-utility notice (14 days within 6 weeks); mandatory conciliation.
  • Section 23 — general prohibition during pendency of conciliation / adjudication / arbitration; settlement / award period.
  • Section 24 — illegal strikes and lock-outs.
  • Section 25 — prohibition of financial aid to illegal action.

36.9 8 · Chapter V-A — Lay-Off, Retrenchment and Transfer (Sections 25A to 25J)

Inserted in 1953, Chapter V-A applies to industrial establishments employing 50 or more workmen (with exceptions) and provides for the rights of workmen affected by lay-off, retrenchment, transfer and re-employment.

36.9.1 Section 25A — Application

The Chapter does not apply to seasonal industrial establishments or establishments employing fewer than 50 workmen on an average per working day during the preceding calendar month.

36.9.2 Section 25B — Continuous Service

A workman is in continuous service if for the preceding calendar year he has worked at least 240 days for the same employer (190 days for underground mines).

36.9.3 Section 25C — Lay-Off Compensation

A laid-off workman is entitled to 50% of basic wages plus dearness allowance for the period of lay-off, for a maximum of 45 days in any 12-month period.

36.9.4 Section 25F — Retrenchment Conditions

No workman who has been in continuous service for at least one year may be retrenched until:

  • One month’s notice in writing has been given (or wages in lieu).
  • Retrenchment compensation equal to 15 days’ average pay for every completed year of continuous service has been paid.
  • Notice to the appropriate government has been served as prescribed.

36.9.5 Section 25G — Last In First Out

Where workmen of a particular category are to be retrenched, the employer must ordinarily retrench the workman who was the last to be employed in that category — the LIFO principle.

36.9.6 Section 25H — Re-Employment

If the employer proposes to re-employ workmen after retrenchment, an opportunity must be given to the retrenched workmen to offer themselves for re-employment in preference to other persons.

NotePYQ anchor — 25F mandatory three conditions

Section 25F — three mandatory pre-conditions before retrenchment: (i) one month’s notice or wages in lieu; (ii) retrenchment compensation = 15 days’ average pay per completed year of service; (iii) notice to government. Failure makes the retrenchment invalid.

36.10 9 · Chapter V-B — Special Provisions Relating to Lay-Off, Retrenchment and Closure (Sections 25K to 25S)

Inserted in 1976, Chapter V-B applies to industrial establishments — not being seasonal — employing 100 or more workmen (raised to 300+ under IR Code 2020) on an average per working day during the preceding 12 months.

TipChapter V-B — Prior Government Permission
Section Provision
25K Chapter applies to non-seasonal establishments with 100+ workmen (300+ under IR Code 2020)
25M Prior permission of the appropriate government required for lay-off (with exceptions for shortage of power or natural calamity)
25N Prior permission required for retrenchment; three months’ notice or wages
25O Prior permission required for closure; ninety days’ notice
25P Government may direct re-opening of an establishment after closure
25Q Penalty for unauthorised lay-off, retrenchment or closure — imprisonment up to one month or fine up to Rs 1,000 or both
25R Penalty for closure without permission — imprisonment up to six months or fine up to Rs 5,000 or both

36.10.1 Constitutional Challenge — Section 25-O

In the Excel Wear v. Union of India (1979) case, the Supreme Court struck down the original Section 25-O (closure provision) as unreasonable under Article 19(1)(g). The provision was redrafted to require reasons for refusal and provide a time-limited government response — restoring its constitutionality.

36.11 10 · Unfair Labour Practices — Schedule V

Schedule V — inserted in 1982 — enumerates unfair labour practices on the part of employers and workmen / unions. Engaging in any of these is an offence under Section 25T and 25U punishable with imprisonment up to six months or fine up to Rs 1,000.

36.11.1 Schedule V — Illustrative Items

TipSchedule V — Unfair Labour Practices
By employers By workmen / unions

Recruitment from outside during a legal strike Engaging in violence or intimidation
Refusal to bargain with the recognised union Demonstrations against management with gheraos
Establishment of “company union” Wilful damage to property
Discharge of a union office-bearer for union activity Demonstrations at office-bearers’ residences

36.12 11 · Recovery of Money Due — Section 33C

Section 33C provides a summary recovery procedure:

  • Section 33C(1) — the appropriate government may recover money due to a workman under a settlement / award by issuing a certificate to the collector who will recover it as arrears of land revenue.
  • Section 33C(2) — where any workman is entitled to benefit capable of being computed in money, the labour court may compute the amount in terms of money.

The provision lets workers cash in awards and settlements without a fresh proceeding.

36.13 12 · Penalties — Sections 26 to 31

TipPenalties under the ID Act 1947
Section Offence Punishment (original Act)
26 Illegal strike / lock-out Workmen: 1 month or Rs 50; Employer: 1 month or Rs 1,000

36.15 14 · The ID Act and the Industrial Relations Code 2020

The Industrial Relations Code 2020 subsumes the ID Act 1947 along with the Trade Unions Act 1926 and the Industrial Employment (Standing Orders) Act 1946. Most of the substantive scheme survives, but several thresholds and procedural details have been recalibrated.

TipID Act 1947 vs IR Code 2020 — Key Changes
Provision ID Act 1947 IR Code 2020
Strike notice Public utilities only (14 days) Universal 14 days for all establishments

Industrial Tribunal Single member (judicial) Two members — judicial + administrative
Labour Court Separate Section 7 tribunal Merged into Industrial Tribunal

Re-skilling fund None Established — employer contributes 15 days’ wages per retrenched worker
Grievance Redressal Committee 20+ workmen (Section 9C) Continued — with women’s representation, time limits
Penalties Modest Substantially enhanced

36.16 15 · Legacy and Continuing Significance

  • The Act remained the central spine of Indian industrial-dispute law for over 70 years.
  • Provided the conceptual vocabulary — industrial dispute, workman, settlement, award, retrenchment, closure, lay-off — that the IR Code 2020 continues to use.
  • Generated a vast body of case-law — Bangalore Water Supply, Workmen of Firestone Tyre, Excel Wear, T.K. Rangarajan and many others — that remains the interpretive foundation under the new Code.
  • Embedded the tripartite model of dispute settlement in Indian industrial practice.
  • Established judicial control over arbitrary management action through Sections 11A, 25F and the unfair labour practice schedule.
