Must Employees Be Notified After an M&A in Vietnam?

One of the buyer's first questions after signing a capital-transfer agreement: must employees be notified, and what must be done correctly when restructuring? A wrong answer can turn a "clean" deal into a collective labor dispute lasting months.

The short answer: a pure capital/share transfer carries no statutory notification duty — but mergers, consolidations, divisions, and separations carry very specific obligations. And even where notification is not mandatory, how employees are handled after M&A decides whether the deal stays "smooth".

1. Two M&A types from a labor perspective

The most common confusion is treating both types the same — while their legal consequences are entirely different.

2. Capital transfers: the employer is unchanged

When an investor buys 100% of capital/shares, the employer remains the same company — the legal person is unchanged; only the owner behind it changes. Therefore:

• All employees' labor contracts continue normally;
• No legal duty arises to notify employees or seek their views on the deal;
• Seniority, regimes, and benefits are fully preserved.

Practical recommendation: the buyer should still issue an early internal announcement about the new owner, with commitments to maintain jobs and HR policies during transition. Total silence after closing is the number-one cause of voluntary resignation waves — especially among middle management.

3. Mergers/consolidations/divisions: duties under Article 42

When M&A takes the form of merger, consolidation, division, or separation, Article 42 of the Labor Code 2019 imposes specific duties on the succeeding employer:

1. Build a workforce utilization plan: who continues, who departs, retraining, job-search support;
2. Consult the grassroots employee representative organization (union) on the plan;
3. Publicly notify employees within 15 days of the plan's adoption;
4. For continuing employees: amend/supplement labor contracts;
5. For departing employees: settle all statutory allowances.

4. Post-M&A restructuring: mass-termination procedure

A frequent real-world pattern: after the capital transfer closes, the buyer restructures — merging departments, cutting overlapping headcount. Terminating many employees for structural, technological, or economic reasons must follow this procedure:

1. Build a workforce utilization plan;
2. Consult the grassroots union;
3. Notify the state labor authority;
4. Prioritize retraining and reassignment before termination;
5. Pay all allowances to departing employees.

Procedural violations (most commonly skipping union consultation) can void the terminations, forcing the company to reinstate employees and pay back wages for days not worked.

5. Benefits employees are entitled to

Depending on the case, employees may receive:

• Severance allowance (Article 46, Labor Code 2019): when contracts end in statutory cases;
• Job-loss allowance (Article 47): for structural/technological/economic terminations — 1 month's salary per year of service, minimum 2 months' salary;
• Unemployment insurance: if contribution conditions are met.

The succeeding employer inherits the payment duty — it cannot shift the burden with "that was the old owner's obligation".

6. The union's role — don't skip it

The grassroots employee representative organization must be consulted when building the workforce utilization plan. In pre-M&A labor due diligence, the buyer should check: does the company have a grassroots union, is the collective labor agreement still valid, are there pending collective disputes. Skipping the union is not just a procedural error — it turns a legal issue into a collective conflict.

7. Buyer's post-closing checklist

1. ☐ Classify the M&A type: pure capital transfer vs merger/consolidation/division/separation
2. ☐ Check grassroots union, collective agreement, pending disputes
3. ☐ Decide on workforce restructuring — if yes, build a workforce utilization plan
4. ☐ Consult the union on the plan (keep minutes)
5. ☐ Publicly notify employees of the plan within the deadline
6. ☐ Amend/supplement contracts of continuing employees
7. ☐ Calculate and provision severance/job-loss allowance budgets
8. ☐ Announce the new owner internally — transparent, early, consistent

8. Three costly mistakes

1. Assuming "buying the company means firing anyone freely" — contracts don't lapse on ownership change; arbitrary termination triggers compensation.
2. Skipping union consultation — the most common procedural error, potentially invalidating the whole workforce plan.
3. Not provisioning allowance budgets in deal pricing — mass job-loss allowances can reach many months of total payroll, breaking the deal's financial model.

9. FAQs

Must employees be notified when 100% of a company's capital is transferred? Labor law does not require formal employee notification for a pure capital/share transfer (the employer — the corporate legal person — is unchanged). In practice, though, transparent internal communication about the new owner and job-security commitments stabilizes morale and prevents post-deal resignation waves.

What are the obligations to employees in a merger or consolidation? For mergers, consolidations, divisions, or separations, Article 42 of the Labor Code 2019 requires the succeeding employer to build a workforce utilization plan, consult the grassroots employee representative organization, and publicly notify employees within 15 days of the plan's adoption. Continuing employees get amended contracts; departing employees receive statutory benefits.

Can the new company conduct mass layoffs to restructure after M&A? Not freely. Terminating many employees for structural, technological, or economic reasons must follow Articles 42–44 of the Labor Code 2019: build a workforce plan, consult the grassroots union, notify the labor authority, prioritize retraining and reassignment. Procedural violations can void the terminations and trigger compensation.

What severance do employees get when losing jobs in post-M&A restructuring? Depending on the case: severance allowance (Article 46), or job-loss allowance (Article 47) for structural/technological/economic terminations — 1 month's salary per year of service, minimum 2 months' salary. Plus unemployment insurance if contribution conditions are met. The succeeding employer inherits the payment duty.

What role does the union play in M&A? The grassroots employee representative organization (usually the union) must be consulted when building the workforce utilization plan (Article 42, Labor Code 2019). Skipping union consultation is the most common procedural error and can invalidate the plan and spark collective disputes.

Do employment contracts automatically terminate when the company is acquired? No. A capital transfer does not change the employer, so contracts continue normally. Even in mergers/consolidations, the succeeding employer must handle employment relations under the adopted workforce plan — contracts do not "expire automatically" because ownership changed.

10. When to work with counsel

Work with counsel for: (i) pre-M&A labor due diligence (union, collective agreements, pending disputes); (ii) building workforce utilization plans in mergers/consolidations; (iii) mass workforce restructuring post-closing; (iv) pricing allowance obligations into deal valuation; (v) handling post-M&A labor disputes.
