India is where strike law “splits into two worlds”: for public utility services, a strike needs 6 weeks’ notice and a gauntlet of timelines; for other industries the law is looser but state governments hold the ultimate weapon — the Essential Services Maintenance Act (ESMA) — which can criminalize strikes. Meanwhile, India’s four new labor codes (effective 21/11/2025) are in the guidance-issuance phase — investors must track them closely.
India: public utilities — 6 weeks’ notice and timeline gauntlets
The Industrial Disputes Act 1947 (Section 22) imposes an especially strict regime on public utility services: workers may not strike in breach of contract if they (a) fail to give the employer notice within six weeks before striking; (b) strike within 14 days of giving notice; (c) strike before the date specified in the notice; (d) strike during conciliation proceedings and 7 days after they conclude.
Section 23 sets general prohibitions: strikes are unlawful during pending conciliation/arbitration/labor-court proceedings and for a period after, or while a settlement/award is in force. Section 24 lists unlawful-strike cases — and the government’s “ultimate weapon” is ESMA: once a service is declared essential, strikes can be banned for a fixed period (usually six months), and defiance can bring criminalization, mass arrests, and instant dismissal.
Transition note: India’s four new labor codes took effect 21/11/2025 and states are issuing implementation guidance — some thresholds and procedures on disputes and strikes may change; investors must check the guidance of the state where the plant sits before applying the old law mechanically.
Vietnam: separating “rights” disputes from “interests” disputes
The key point many Indian investors miss coming to Vietnam: the Labour Code 2019 splits collective labor disputes into two types with completely different resolution tracks (Articles 196–197).
Rights disputes — over applying existing law, agreements, or work rules (e.g., did the company pay allowances per the agreement?) — go through labor mediators, labor arbitration councils, then courts; no strike allowed. Interest disputes — bargaining new terms not yet in law/agreements (e.g., demanding above-scale wage hikes) — go through mediation, arbitration, then strike (Articles 198–205).
Confusing the two is a common mistake: striking over a “right” already provided by law (e.g., demanding overtime pay per Article 98) is an unlawful strike — that dispute type belongs to mediation/arbitration/courts, not strikes.
Side by side: timeline barriers vs classification barriers
Control mechanism: India controls through timelines (6 weeks, 14 days, 7 days) and government ban powers (ESMA). Vietnam controls through dispute classification (rights vs interests) and multi-step procedure.
Criminalization: India is higher — ESMA can turn strikes into criminal offenses. Vietnam: unlawful strikes mainly bring civil, administrative, and disciplinary consequences.
Predictability: both demand investors master procedural law. In India, a compliance timeline must be drawn before any sign of dispute; in Vietnam, HR must master a dispute “classification map.”
Practical recommendations
First, in India, determine immediately whether the business is a “public utility service” — the 6-week/14-day/7-day regime applies only to that group, and misclassification skews the whole response strategy. Second, track the implementation guidance for the four new labor codes in the plant’s state — the 2025–2026 transition is the highest legal-risk period. Third, in Vietnam, train HR to distinguish rights disputes from interest disputes — the “switch” deciding whether a dispute takes the mediation/court track or the strike track.
Frequently asked questions
How do public utility workers strike in India?
Under Section 22 of the Industrial Disputes Act 1947: notice within six weeks before striking, no strike within 14 days of notice, not before the date in the notice, and not during conciliation plus 7 days after conciliation ends.
What is ESMA and how dangerous is it?
The Essential Services Maintenance Act lets the government ban strikes in a declared essential service (usually six months). Striking in defiance can be criminalized, with mass arrests and instant dismissal.
What do India’s four new labor codes change?
Effective 21/11/2025, with states issuing implementation guidance. Some thresholds and procedures on disputes and strikes may change — investors must check the guidance of the plant’s state rather than applying the old law mechanically.
How do rights and interest disputes differ in Vietnam?
Rights disputes (applying existing law/agreements/rules): resolved via mediators, arbitration, courts — no strike. Interest disputes (bargaining new terms): via mediation, arbitration, then strike (Articles 198–205). Wrong classification means an unlawful strike.
Can workers strike to demand statutory overtime pay?
No — if the law/agreement already provides that right. That is a rights dispute for mediators, arbitration councils, or courts. Striking in that case is unlawful under Articles 204–205 of the Labour Code 2019.
