1. Introduction

A strike is one of the important methods through which workers collectively express their grievances against an employer. Employees may resort to a strike to demand higher wages, improved working conditions, implementation of settlements, job security, or the resolution of industrial disputes.

However, the right to strike is not absolute. Indian labour law prescribes specific conditions and procedural requirements that workers and trade unions must comply with before commencing a strike. Strike notice compliance refers to fulfilling the statutory requirements relating to advance notice, the timing of the strike, conciliation proceedings, and other legal restrictions.

The principal legislation governing this subject is the Industrial Disputes Act, 1947, particularly Sections 2(q), 22, 23, 24 and 26. The Industrial Relations Code, 2020, also contains provisions governing strikes and lockouts, and its commencement and applicable transitional arrangements must be considered when examining a dispute arising in 2026.

2. Meaning of a strike

Under Section 2(q) of the Industrial Disputes Act, 1947, a strike generally means a cessation of work by a body of persons employed in an industry acting in combination, or a concerted refusal by such persons to continue working or accept employment.

The essential elements of a strike are:

There must be a cessation of work or a concerted refusal to work.

The action must involve a body of workers or a collective refusal.

The workers must act in combination or in concert.

The action must fall within the statutory definition of a strike.

A strike differs from an individual employee's absence because it ordinarily involves collective action connected with an employment-related demand or dispute.

3. Legal framework governing strike notices

The relevant provisions under the Industrial Disputes Act, 1947, are:

The distinction between Sections 22 and 23 is particularly important. Section 22 prescribes special notice requirements for public utility services, whereas Section 23 imposes restrictions applicable more generally to industrial establishments covered by the Act.

4. Strike notice requirements under the Industrial Relations Code, 2020

Important current-law note: The Government of India announced that the four Labour Codes, including the Industrial Relations Code, 2020, came into force on 21 November 2025. Therefore, for a strike occurring in October 2026, the Industrial Relations Code, 2020, is the starting point for legal analysis, subject to applicable rules, notifications and transitional provisions.

A. Fourteen days' advance notice

Section 62 of the Industrial Relations Code, 2020, establishes the statutory framework governing strikes and lockouts.

Workers covered by the Code must comply with its notice requirements before commencing a strike. In particular, a strike cannot be commenced without the required advance notice, and the prescribed notice period must be observed.

The notice requirement serves several purposes:

It gives the employer an opportunity to understand the workers' demands.

It allows negotiations to take place before work stops.

It provides an opportunity for conciliation and dispute resolution.

It helps prevent sudden industrial disruption.

A union should therefore avoid announcing or commencing a strike without first checking the statutory notice requirements applicable to the establishment.

B. Restrictions on the timing of a strike

Giving notice does not automatically make every subsequent strike lawful. Workers must also ensure that the strike does not commence during a prohibited period.

Relevant restrictions under the Industrial Relations Code include restrictions connected with conciliation proceedings, adjudication, arbitration, settlements, awards and applicable statutory orders.

For compliance purposes, the union should check the status of any pending industrial dispute and whether a legal restriction applies on the proposed date.

C. Notice and communication records

A union should maintain reliable evidence of compliance, including:

A copy of the strike notice.

The date on which the notice was issued.

Proof of delivery to the appropriate employer or authority, where required.

A copy of the union resolution authorising the proposed action, where applicable.

Records of negotiations and conciliation meetings.

Any subsequent withdrawal, postponement or modification of the proposed strike.

These records can become important if the employer later challenges the legality of the strike.

D. Detailed requirements under Section 62

The following table summarises the principal restrictions under Section 62 of the Industrial Relations Code, 2020.

These restrictions are statutory requirements, not merely recommendations.

E. Illustration of the 14-day notice rule

Suppose a workers' union gives a strike notice on 1 November 2026 and proposes to commence a strike on 20 November 2026.

The union must verify that the notice was served in the legally prescribed manner.

The proposed date must satisfy the 14-day waiting requirement.

The strike must occur within the permitted 60-day notice window.

No other statutory prohibition must apply.

A notice alone does not guarantee legality. If conciliation proceedings or another statutory restriction prevent the strike on the proposed date, the union must comply with that restriction as well.

5. What should a valid strike notice contain?

A practical strike notice should clearly identify the proposed industrial action and allow the employer to understand the dispute.

The following details should ordinarily be included:

Name of the trade union: The union issuing the notice.

Name and address of the employer: The establishment against which the proposed strike is directed.

Details of workers concerned: The relevant employees, department or category of workers.

Statement of demands: For example, unpaid wages, revision of wages, or implementation of an existing agreement.

Proposed date of strike: The date on which workers intend to stop work, subject to statutory restrictions.

Purpose of the strike: A concise explanation of the unresolved industrial dispute.

Authorisation: The name, designation and signature of the authorised union representative, as appropriate.

Service and proof of delivery: Evidence that the notice was delivered in the prescribed manner.

Legal qualification: These are practical drafting recommendations, not a substitute for the exact statutory form and service requirements prescribed by the applicable rules. The Code requires notice to be given by the prescribed number of persons, to the prescribed recipient or recipients, and in the prescribed manner.

6. Important case laws on strike notice compliance and legality

The following seven judicial decisions explain the legal principles governing strikes, statutory restrictions, justification, and workers' entitlement to wages. Although several were decided under the Industrial Disputes Act, 1947, their principles remain relevant where consistent with the current Industrial Relations Code, 2020.

Case 1: B.R. Singh v. Union of India (1989)

Citation: (1989) 4 SCC 710

Court: Supreme Court of India

Facts: The dispute concerned industrial action by workers and disciplinary action taken against trade union leaders. The legality of the strike and the restrictions imposed on workers' collective action were considered.

Judgment: The Supreme Court recognised that the right to strike is an important weapon available to workers in collective bargaining. However, it clarified that this right is not absolute and is subject to statutory restrictions.

Legal principle: A strike must be assessed according to the applicable statutory provisions. A court should not treat a strike as illegal merely because the employer disapproves of it; the relevant legal prohibitions must be examined.

Relevance to notice compliance: A trade union must comply with the applicable notice and other statutory requirements. The existence of a legitimate grievance does not excuse non-compliance with mandatory legal restrictions.

Case 2: Syndicate Bank v. K. Umesh Nayak (1994)

Citation: (1994) 5 SCC 572

Court: Supreme Court of India

Facts: The dispute concerned whether employees were entitled to wages for the period during which they participated in a strike.

Judgment: The Constitution Bench held that, to claim wages for a strike period, the strike must be both legal and justified. Legality and justification are separate questions that must be assessed on the facts and evidence.

Legal principle: The mere fact that a strike is lawful does not automatically establish entitlement to wages for the strike period.

Relevance to notice compliance: A union should comply with statutory notice requirements and ensure that the strike has a legitimate basis. Even a procedurally lawful strike may raise a separate question about wages.

Case 3: Bank of India v. T.S. Kelawala (1990)

Citation: (1990) 4 SCC 744

Court: Supreme Court of India

Facts: The case concerned an employer's authority to deduct wages for the period during which employees participated in a strike.

Judgment: The Supreme Court held that the question of wages for a strike period is distinct from the legality of the strike. The employer could deduct wages for the period during which employees did not work, subject to the applicable legal framework.

Legal principle: The principle of “no work, no pay” may apply to strike periods.

Relevance to notice compliance: Giving a valid strike notice does not itself guarantee payment of wages for the strike period. Workers should understand the financial consequences of industrial action.

Case 4: Churakulam Tea Estate (P) Ltd. v. Workmen (1969)

Citation: AIR 1969 SC 998

Court: Supreme Court of India

Facts: The dispute involved workers' entitlement to wages for a period of strike and the circumstances surrounding the industrial action.

Judgment: The Court recognised the importance of examining both the legality and justification of a strike when determining entitlement to strike-period wages.

Legal principle: A strike's legal status and the reasonableness of the workers' action are distinct considerations.

Relevance to notice compliance: A union should not focus solely on giving notice. It should also maintain evidence of its grievances, prior negotiations, and the circumstances that led to the proposed strike.

Case 5: Crompton Greaves Ltd. v. Workmen (1978)

Citation: (1978) 3 SCC 155

Court: Supreme Court of India

Facts: The case concerned the consequences of a strike and workers' claim to wages for the period of industrial action.

Judgment: The Supreme Court's decision formed part of the line of authority establishing that a strike must be both legal and justified for workers to be entitled to wages for the strike period.

Legal principle: Compliance with legal requirements and justification for the strike must be considered separately.

Relevance to notice compliance: A union should preserve evidence of compliance with the statutory notice procedure and the underlying dispute. A lawful notice does not resolve every question about the consequences of the strike.

Case 6: India General Navigation and Railway Co. Ltd. v. Their Workmen (1960)

Citation: AIR 1960 SC 219

Court: Supreme Court of India

Facts: The case concerned industrial action and the restrictions governing strikes, including the legal position of strikes in public utility services.

Judgment: The Court examined the statutory restrictions applicable to strikes and the consequences of non-compliance.

Legal principle: Where legislation makes compliance with prescribed strike restrictions mandatory, failure to comply can affect the legality of the industrial action.

Relevance to notice compliance: A union must determine whether special statutory requirements apply to its establishment and must not assume that the ordinary procedure is sufficient in every case.

Case 7: Management of Chandramalai Estate v. Its Workmen (1960)

Citation: AIR 1960 SC 902

Court: Supreme Court of India

Facts: The dispute involved workers resorting to a strike after unsuccessful efforts to resolve an industrial dispute.

Judgment: The Supreme Court criticised the decision to proceed with a strike without allowing a reasonable opportunity for the dispute-resolution process to run its course.

Legal principle: The circumstances leading to a strike, including the conduct of negotiations and conciliation efforts, may be relevant to determining whether the strike was justified.

Relevance to notice compliance: Workers should document their demands, negotiations and attempts at settlement. Procedural compliance and responsible engagement with dispute-resolution mechanisms can be important in subsequent proceedings.

Note: These decisions do not all interpret Section 62 of the Industrial Relations Code, 2020, directly. They are included for the established principles of Indian strike law, with their application subject to the current statutory framework.

7. Consequences of non-compliance with strike notice requirements

Failure to comply with mandatory statutory restrictions can have serious consequences.

A. The strike may be illegal

Under Section 63 of the Industrial Relations Code, 2020, a strike may be illegal if it is commenced or declared in contravention of Section 62, or continued in contravention of an applicable order under Section 42(7).

B. Disciplinary consequences

Participation in an illegal strike may expose workers to disciplinary proceedings, subject to the applicable legislation, standing orders, service rules and principles of natural justice.

However, an employer should not assume that every strike or every act of participation automatically justifies dismissal. The circumstances and applicable legal protections must be considered.

C. Financial consequences

Workers may lose wages for the strike period. As explained in Syndicate Bank v. K. Umesh Nayak, legality alone does not guarantee entitlement to strike-period wages.

D. Statutory penalties

The Industrial Relations Code provides penalties for illegal strikes and related conduct. The precise provision and penalty applicable must be determined under the current Code and the relevant facts.

E. Dispute resolution proceedings

The employer, union or affected workers may seek appropriate remedies before the competent labour authorities or adjudicatory bodies, depending on the nature of the dispute.

8. Practical compliance checklist for trade unions

Before commencing a strike, the union should verify the following:

Pre-strike compliance review

0 of 9

Identify the applicable legislation and rules.

Confirm that the establishment and workers fall within the relevant statutory framework.

Prepare and serve the strike notice in the prescribed manner.

Calculate the 14-day waiting period and 60-day notice window correctly.

Check for pending conciliation, Tribunal or arbitration proceedings.

Check whether a binding settlement or award covers the dispute.

Check for any applicable prohibition order.

Retain the notice, delivery proof, union records and negotiation documents.

Obtain advice from a qualified labour-law professional if legality is uncertain.

9. Conclusion

Strike notice compliance is an essential element of lawful industrial action in India. Under the Industrial Relations Code, 2020, workers must observe the prescribed advance notice period, the permitted notice window, and the restrictions connected with conciliation, adjudication, arbitration, settlements and awards.

The Supreme Court's decisions, including B.R. Singh, Syndicate Bank, Churakulam Tea Estate and Crompton Greaves, demonstrate that the legality of a strike, its justification and entitlement to wages are separate legal questions.

The central rule is that a genuine industrial grievance does not, by itself, excuse failure to comply with mandatory statutory requirements. Trade unions should therefore verify the applicable law, serve the notice correctly, preserve evidence and check all restrictions before commencing a strike.
