35 The Industrial Disputes Act, 1947
This chapter consolidates the Industrial Disputes Act, 1947 — the umbrella statute that has defined Indian industrial relations for more than seven decades. Earlier chapters in this module touched on specific provisions; this chapter walks through the Act systematically — its definitions, its authorities, its dispute-handling architecture, and its position under the Industrial Relations Code, 2020.
35.1 Background and Genesis
The colonial Trade Disputes Act, 1929 offered the first statutory framework for industrial disputes in India, but it was widely seen as inadequate — it provided for court of inquiry and board of conciliation only, and did not give the government power to refer disputes for adjudication. The need for a stronger framework was urgent in the post-war period of rising industrial unrest.
The Industrial Disputes Act, 1947 — passed by the Constituent Assembly (Legislative) on 11 March 1947 — replaced the 1929 Act with a much wider regime: a chain of adjudication bodies, broader definitions, and powers for the appropriate government to compulsorily refer disputes. It came into force on 1 April 1947.
35.2 Object of the Act
The preamble states the object: “to make provision for the investigation and settlement of industrial disputes, and for certain other purposes.”
TipFive Objects of the Act
| Object | What it does |
|---|---|
| Investigation and settlement | Provides machinery for conciliation, arbitration and adjudication |
| Promotion of industrial peace | Discourages strikes and lockouts through cooling-off periods and notice requirements |
| Prevention of disputes | Works Committees and Standing Orders to address disputes at source |
| Protection of workers | Restrains arbitrary discharge, retrenchment and closure |
| Settlement of conditions of employment | Provides binding awards and settlements |
35.3 Coverage and Application
The Act applies to the whole of India. It covers industrial establishments as defined by §2(j) and applies to workmen as defined by §2(s).
35.3.1 Industry — Section 2(j)
The definition of industry in §2(j) has been one of the most litigated provisions of Indian labour law. The Supreme Court’s seminal judgment in Bangalore Water Supply v. A. Rajappa (1978) gave the most expansive interpretation: industry is any systematic activity organised by cooperation between employer and employee for the production or distribution of goods or services calculated to satisfy human wants — irrespective of profit motive.
The Bangalore Water Supply test is the standard. It expanded industry to include hospitals, charitable institutions, government departments and non-profit organisations.
35.3.2 Workman — Section 2(s)
A workman under §2(s) is any person employed in an industry to do any manual, unskilled, skilled, technical, operational, clerical or supervisory work for hire or reward, excluding:
- those employed mainly in a managerial or administrative capacity;
- those employed in supervisory capacity drawing wages exceeding ₹10,000 per month (the threshold has been periodically revised);
- those subject to the Air Force, Army, Navy Acts;
- those employed in police, prison or as detective.
The exclusion of managerial and administrative employees is one of the most-tested aspects of the definition.
35.4 Key Definitions — Section 2
TipImportant Definitions under Section 2
| Section | Term | Meaning |
|---|---|---|
| 2(a) | Appropriate government | Central government for railways, banks, mines, oil-fields, ports, etc.; state government for other industries |
| 2(b) | Award | Interim or final determination of any industrial dispute by a Labour Court, Tribunal or NIT |
| 2(g) | Trade dispute / now industrial dispute | (Repealed; replaced by §2(k)) |
| 2(j) | Industry | Systematic activity for production or distribution of goods or services (Bangalore Water Supply test) |
| 2(k) | Industrial dispute | Any dispute between employers and employers, employers and workmen, or workmen and workmen, connected with employment, non-employment, terms or conditions |
| 2(l) | Lock-out | Temporary closing of place of employment, suspension of work, or refusal by employer to continue to employ |
| 2(p) | Settlement | A settlement arrived at in conciliation proceedings, or a written agreement |
| 2(q) | Strike | Cessation of work by a body of persons employed in industry acting in combination |
| 2(s) | Workman | As described above |
| 2(kkk) | Lay-off | Failure / refusal / inability of the employer to give employment for reasons specified |
| 2(oo) | Retrenchment | Termination by employer of service of a workman for any reason whatsoever (with specified exceptions) |
| 2(cc) | Closure | Permanent closing down of place of employment or part of it |
| 2A | Individual dispute deemed industrial | Individual termination disputes deemed industrial disputes (added 1965, refined 2010) |
35.6 Reference of Disputes — Section 10
Section 10 is the trigger of the entire dispute-handling machinery. Where the appropriate government is of opinion that an industrial dispute exists or is apprehended, it may refer the dispute, by order in writing, to a:
- Board of Conciliation — for promoting a settlement;
- Court of Inquiry — for inquiring into any matter connected with the dispute;
- Labour Court — for adjudication of matters in the Second Schedule;
- Industrial Tribunal — for adjudication of matters in the Second or Third Schedule;
- National Industrial Tribunal — for disputes of national importance.
The reference may be made suo motu (on the government’s own motion) or on the application of the parties.
35.6.1 Section 10A — Voluntary Arbitration
Where the parties agree, they may refer the dispute to an arbitrator before adjudication has begun. The arbitrator’s award is binding on the parties.
35.7 Schedules to the Act
The Act has five schedules. The most-tested are the Second, Third and Fifth.
TipThe Five Schedules of the ID Act
| Schedule | Subject |
|---|---|
| First | Industries declared as public utility services |
| Second | Matters within the jurisdiction of Labour Courts (e.g. propriety of standing orders, discharge / dismissal, withdrawal of customary concessions, illegality of strikes/lockouts) |
| Third | Matters within the jurisdiction of Industrial Tribunals (e.g. wages, hours, leave, retrenchment, classification of grades — broader and more substantive matters) |
| Fourth | Conditions of service for changes that require notice (Section 9A) |
| Fifth | Unfair labour practices on the part of employers and workmen (added 1982) |
35.7.1 Section 9A — Notice of Change
Section 9A requires the employer to give 21 days’ notice before effecting any change in conditions of service of workmen specified in the Fourth Schedule. The Schedule covers wages, hours, leave, withdrawal of customary concessions, introduction of new technology that may displace workers, and other substantive matters.
35.8 Strikes and Lockouts — Sections 22 to 25
Chapter 33 covered strikes and lockouts in detail. The relevant ID Act provisions are recalled here.
TipStrike and Lockout Provisions
| Section | Subject |
|---|---|
| §22 | Notice and conditions for strike / lockout in public utility services |
| §23 | General prohibitions on strikes / lockouts during conciliation, court / tribunal proceedings, etc. |
| §24 | Strikes / lockouts in contravention of §22 or §23 are illegal |
| §25 | Prohibition on financial aid to illegal strikes / lockouts |
35.9 Lay-off, Retrenchment and Closure — Chapters VA and VB
Two specialised chapters of the Act govern lay-off, retrenchment and closure.
35.9.1 Chapter VA — Smaller Establishments
Applies to industrial establishments with fewer than 50–100 workers (as prescribed). Provisions include:
- §25A — Application of Chapter VA;
- §25C — Right of workmen laid off to compensation (50% of basic + DA);
- §25E — Workmen not entitled to compensation in certain cases;
- §25F — Conditions precedent to retrenchment of workmen (notice + compensation);
- §25G — Last-come-first-go rule for retrenchment;
- §25H — Re-employment of retrenched workmen;
- §25J — Effect of laws inconsistent.
35.9.2 Chapter VB — Establishments with 100+ Workers
Applies to industrial establishments with 100 or more workers (raised to 300 under the IR Code).
TipChapter VB Provisions
| Section | Provision |
|---|---|
| §25K | Application of Chapter VB |
| §25M | Prohibition of lay-off — prior permission required |
| §25N | Conditions precedent to retrenchment — prior permission required |
| §25-O | Procedure for closing down an undertaking — 90-day notice and government permission |
| §25Q | Penalty for lay-off / retrenchment without prior permission |
| §25R | Penalty for closure without permission |
The IR Code, 2020 raises the threshold for Chapter VB application from 100 to 300 workers — one of the most-debated changes.
35.10 Section 33 — Protection during Pendency
Where a dispute is pending before a conciliation officer, board, court or tribunal, the employer:
- cannot alter, to the worker’s prejudice, the conditions of service applicable;
- cannot discharge, dismiss or punish a worker for any matter connected with the dispute;
without the prior written permission of the authority before which the proceeding is pending.
§33A allows a worker aggrieved by a §33 contravention to complain directly to the authority.
35.11 Awards and Settlements — Sections 17, 18, 19
TipAward and Settlement Provisions
| Section | Provision |
|---|---|
| §17 | Awards published by appropriate government within 30 days; enforceable on day 31 |
| §17A | Government may, by order, declare an award not to be enforceable for stated reasons |
| §18 | Binding effect of settlements and awards (chapter 32) |
| §19 | Period of operation of settlements and awards (chapter 32) |
| §20 | Commencement and conclusion of conciliation proceedings |
| §21 | Limited disclosure of certain matters by conciliation officers |
35.12 Unfair Labour Practices — Fifth Schedule
The Fifth Schedule, added by the 1982 amendment, lists unfair labour practices on the part of employers (Part I) and workmen and trade unions (Part II). Section 25T prohibits any person from committing an unfair labour practice.
TipExamples of Unfair Labour Practices
| On the part of employers (Part I) | On the part of workmen / unions (Part II) |
|---|---|
| Interference with workers’ right to organise | Compelling membership in a particular union |
| Threats and reprisals against union members | Threats or assaults against non-members or other unions |
| Establishing employer-sponsored unions | Forcing recognition through coercion |
| Refusing to bargain collectively in good faith | Refusing to bargain collectively in good faith |
| Discharging workers for union activity | Stage-managed strikes / lockouts |
| Recruiting workers during a legal strike | Indulging in violence during disputes |
| Indulging in acts of force or violence | Engaging in slow-down or sabotage |
| Showing favouritism in promotions | Withdrawing co-operation in maintenance of essential services |
35.13 Penalties — Sections 25U to 31
The Act prescribes penalties for various offences.
TipMajor Penalty Provisions
| Offence | Penalty |
|---|---|
| Illegal strike — workers (§26(1)) | Imprisonment up to 1 month or fine, or both |
| Illegal lockout — employer (§26(2)) | Imprisonment up to 1 month or fine, or both |
| Instigation of illegal strike / lockout (§27) | Imprisonment up to 6 months or fine, or both |
| Unfair labour practice (§25U) | Imprisonment up to 6 months or fine, or both |
| Lay-off / retrenchment without permission (§25Q) | Imprisonment up to 1 month or fine |
| Closure without permission (§25R) | Imprisonment up to 6 months or fine |
| Disclosure of confidential information (§30) | Imprisonment up to 6 months or fine |
| Other offences (§31) | Fine — varies by offence |
The original penalties were modest. The IR Code, 2020 has revised them upward and added compounding provisions.
35.14 Special Provisions
A few specific provisions deserve mention.
TipOther Important Sections
| Section | Provision |
|---|---|
| §11 | Procedure and powers of conciliation officers, boards, courts |
| §11A | Power of Labour Courts and Tribunals to give appropriate relief in cases of discharge or dismissal |
| §17B | Payment of full wages to workmen pending proceedings in higher courts (where reinstatement award challenged) |
| §29 | Penalty for breach of settlement or award |
| §36 | Representation of parties — by union representative, lawyer (with consent), etc. |
| §36A | Power of government to give consent to legal practitioners |
| §38 | Power to make rules |
| §39 | Delegation of powers |
35.14.1 Section 11A — A Critical Power
Section 11A, added in 1971, is one of the most consequential provisions. It allows Labour Courts and Tribunals reviewing a discharge or dismissal to substitute their own view for that of the employer — even where the misconduct is proved, if the punishment is disproportionate. Before §11A, the tribunal could only set aside the dismissal on procedural grounds; after §11A, it can reduce the punishment on substantive grounds.
35.15 Position under the IR Code, 2020
The IR Code, 2020 has repealed the Industrial Disputes Act, 1947 (along with the Trade Unions Act and the Standing Orders Act) and consolidated their provisions. The major continuities and changes:
TipID Act 1947 → IR Code 2020 — Key Changes
| Element | ID Act 1947 | IR Code 2020 |
|---|---|---|
| Adjudication | Three-tier (Labour Court / IT / NIT) | Two-tier — single Industrial Tribunal (judicial + administrative members) and NIT |
| Strike notice | 14-day in public utilities only | 14-day in all industrial establishments |
| Lay-off / retrenchment / closure permission | 100+ workers | 300+ workers |
| Standing orders threshold | 100 workers | 300 workers |
| Grievance Redressal Committee | 20+ workers (added 2010) | Retained at 20+ workers |
| Negotiating union | No statutory framework | Sole negotiating union (≥ 51%); negotiating council (≥ 20%) |
| Fixed-term employment | Recognised by 2018 amendment | Explicitly retained |
| Re-skilling fund for retrenched workers | None | New provision under the Code |
The IR Code is a consolidation exercise — it preserves most ID Act doctrines while raising thresholds, simplifying tribunal architecture and adding new concepts (recognition, fixed-term, gig and platform workers).
35.16 Significance of the Act
TipWhy the ID Act Has Mattered
| Significance | What it produced |
|---|---|
| Consolidated dispute-handling machinery | Single statutory framework for IR |
| Compulsory adjudication | The state’s power to refer disputes — distinctive Indian feature |
| Statutory protection for workers | §2A, §25F, §11A, §33 — pro-worker provisions accumulated over decades |
| Generated a vast body of case law | Bangalore Water Supply, Workmen of Dimakuchi Tea Estate, Hindustan Lever Workmen Union and many others |
| Shaped Indian industrial relations | Almost every aspect of formal-sector IR has been governed by this Act |
| Pluralist orientation | Balanced (broadly) the interests of workers, employers and the state |
The ID Act, 1947 — and now its successor the IR Code, 2020 — is the foundational labour-law statute in India. The next module turns to labour legislation in the broader sense: workplace safety, wages, welfare and social security.
