Labour and Industrial Relations Due Diligence in a Factory Acquisition

Labour due diligence in a factory acquisition should determine whether the workforce model can sustain production, remain compliant and navigate the change of control without unmanaged cost or disruption. Headcount and payroll are only the starting point. Investors need to reconcile people with shifts and output, test worker categories and contractor arrangements, understand industrial-relations history and quantify liabilities, retention needs and integration constraints.

Establish the workforce perimeter

Build a roster by legal entity, site, department, shift, grade, skill, employment category and supervisor. Reconcile HR records with payroll, attendance, access control, contractor registers and production rosters. Include permanent, fixed-term, probationary, trainee, apprentice, contract, migrant and other worker populations as applicable.

Investigate ghost workers, duplicate identifiers, people paid by one entity but directed by another, and contractor labour performing enduring core roles. Legal status depends on facts and current law, not the label in a spreadsheet. Employment counsel should assess classification and principal-employer exposure.

Map headcount to lines, shifts and constraint processes. This reveals whether forecast output assumes overtime, vacancies, a new shift or productivity gains that have not been resourced.

Rebuild the full labour cost

Reconcile gross wages, allowances, overtime, incentives, bonus, leave, social-security contributions, gratuity and other benefits with the general ledger and statutory records. Include contractor service charges, transport, canteen, uniforms, medical, housing and training where material.

Analyse cost by shift, product or work centre where possible. A low direct-labour rate may depend on chronic overtime or under-resourced maintenance and quality teams. Separate recurring cost from arrears, settlements and one-time incentives. Test whether wage increases, collective agreements, minimum rates or benefit changes are reflected in the forecast.

Accrued accounting liabilities may differ from cash obligations. Actuarial, accounting, tax and legal specialists should review employee-benefit calculations and transaction treatment.

Test current compliance, including the labour-code transition

India's four labour codes came into force on 21 November 2025, and the Ministry of Labour & Employment's current portal includes 2026 central rules, implementation materials and FAQs. Diligence in 2026 should therefore review the codes, applicable central or state rules and notifications, and the target's transition from earlier regimes. Requirements can depend on establishment, industry, worker category, appropriate government and state implementation.

Review appointment documentation, wage calculations and deductions, working hours, overtime, leave, registers, notices, social-security enrolment and remittances, occupational health and safety, welfare, contractor licensing or registration, migrant-worker arrangements and equal-opportunity obligations as applicable. Test samples to bank payment and government portal receipts.

Do not rely on a consultant's compliance certificate without source evidence. Reconcile employee counts and wage bases across filings; inconsistent populations can reveal omissions. Review inspections, show-cause notices, prosecutions, claims and unresolved corrective actions. Specialist counsel should confirm the current legal position.

Understand industrial relations as a system

List registered or recognised unions, negotiating arrangements, works or grievance committees, collective agreements, settlements, standing orders or applicable model terms, and pending demands. Review disputes, strikes, lockouts, go-slows, absenteeism, disciplinary cases and tribunal or court matters over a representative period.

Interview management and workforce representatives where deal protocols permit. Focus on causes and credibility: wage compression, supervisor behaviour, safety, contractor use, productivity schemes, transfers, automation and past commitments. A period without a strike does not prove stable relations if grievances are unresolved or a settlement expires soon after closing.

Assess whether the transaction, workforce transfer or planned restructuring triggers notice, consultation, consent, compensation or government approval. Requirements vary by structure and facts, and must be determined by counsel before decisions are communicated.

Identify critical skills and key-person dependency

A plant can be labour-compliant yet operationally fragile. Build a skill matrix for licensed operators, tool setters, maintenance technicians, programmers, laboratory staff, process engineers and supervisors. Review vacancies, age profile, attrition, training time, succession and use of retired or informal experts.

Check whether process knowledge, passwords, recipes or troubleshooting remain undocumented. Retention decisions should consider individual criticality, shift coverage and market replacement time—not hierarchy alone. Plan communications carefully; premature or inconsistent messages can create avoidable departures.

Examine contractors as operational and liability risk

Map each contractor, scope, workforce, site, licence or registration, wage and social-security evidence, safety performance, tenure and dependency. Trace a sample from contract and attendance through wage payment and statutory remittance. Inspect actual supervision and integration with the target's work.

Contractor failure can stop production even when the legal exposure ultimately sits elsewhere. Consider replacement lead time, mobilisation, security access, skill certification and industrial-relations consequences. Review concentration where one vendor provides most workers or essential services.

Connect workforce evidence to the deal model

Model realistic productivity and automation cases. Savings require consultation, training, capex, ramp and safety controls. Do not value headcount reduction before the legal process and operating feasibility are understood. EBITDA is not cash flow; include severance, retention, recruitment and working-capital effects.

Depending on advice, the deal may require conditions, employee-transfer provisions, warranties, indemnities, escrow or agreed communications. Immediate wage, safety or social-security issues should be corrected rather than left to contractual allocation. The transaction and business reengineering services page provides related context.

Conclusion

Workforce diligence connects legal compliance, shop-floor capability and human behaviour with cash flow. A defensible view shows who performs the work, what the model truly costs, where liabilities or disruption could arise and how the buyer will preserve trust and production through closing.
