Cross‑border M&A Lawyers Germany 2026: Betriebsübergang, Works Council & Redundancies

Cross‑border M&A deals involving German operations carry a layer of employment‑law complexity that can delay closings, inflate costs and expose buyers to inherited liabilities running into millions of euros.

The first half of 2026 has sharpened those risks: selected provisions of the BRUBEG (Bankenrichtlinienumsetzungs‑ und Bürokratieentlastungsgesetz) took effect on 1 April 2026, adding new prudential and ESG‑related workforce obligations for banking targets; the EU Pay Transparency Directive (2023/970) must be transposed by 7 June 2026, requiring salary‑range disclosure and pay‑gap reporting that will reshape post‑close HR integration; and ongoing proposed changes to German real‑estate transfer tax (Grunderwerbsteuer / REtt) continue to influence whether acquirers structure transactions as share deals or asset deals, a choice that directly determines whether a Betriebsübergang triggers automatic employee transfer.

This guide is designed for general counsel, HR directors and cross‑border M&A lawyers in Germany who need a practical, deal‑stage compliance roadmap covering Betriebsübergang mechanics, works‑council consultation duties, redundancy law and SPA risk allocation.

Legal Framework: Betriebsübergang Under §613a BGB and the Betriebsverfassungsgesetz

German employee‑transfer law is anchored in two primary statutes. §613a BGB governs the Betriebsübergang, the automatic transfer of employment relationships when a business or part of a business passes to a new owner by legal transaction. The Betriebsverfassungsgesetz (BetrVG) regulates the rights, information and co‑determination powers of works councils in any transaction that affects the workforce. Together, these statutes create a mandatory framework that cannot be contracted around: parties to a cross‑border M&A transaction in Germany must comply regardless of the governing law chosen for the SPA itself.

Key Statutory Texts

Under §613a(1) BGB, if a business or part of a business passes to a new owner (Inhaber) by legal transaction, the new owner steps into the rights and obligations of the existing employment relationships at the date of transfer. Employees retain all contractual terms, salary, notice periods, accrued holiday, supplementary pension entitlements, and those terms may not be changed to the employee’s detriment on account of the transfer for at least one year (§613a(1) sentence 2 BGB). Employers must provide affected employees with written notice of the transfer covering the identity of the buyer, the date and reason for the transfer, the legal, economic and social consequences, and any measures envisaged for the employees (§613a(5) BGB).

Each employee then has one month from receipt of proper notice to object to the transfer (§613a(6) BGB); an objecting employee’s contract remains with the seller, which often leads to redundancy where the seller has no remaining operation.

The BetrVG complements this by granting the works council (Betriebsrat) specific information, consultation and co‑determination rights that apply before, during and after a transaction. Sections 111–113 BetrVG are the most deal‑critical: they require timely information on planned operational changes (Betriebsänderungen), negotiation of a reconciliation of interests (Interessenausgleich) and, where agreement cannot be reached, a social plan (Sozialplan) enforceable through a conciliation board (Einigungsstelle).

BAG Jurisprudence and EU Law (Directive 2001/23/EC)

German courts apply §613a BGB in line with EU Directive 2001/23/EC on the safeguarding of employees’ rights in transfers of undertakings. The Bundesarbeitsgericht (BAG) has developed an identity test to determine whether a Betriebsübergang has occurred. The court examines whether an economic entity retains its identity after transfer, weighing factors such as the type of undertaking, whether tangible or intangible assets are transferred, whether the majority of employees are taken over, whether customers are transferred, the degree of similarity between pre‑ and post‑transfer activities, and any period of interruption (BAG, 8 AZR 158/07).

In a landmark ruling (BAG, 8 AZR 538/08), the court confirmed that a mere continuation of the same activity is not sufficient, the transferred unit must preserve its organisational autonomy. These principles have particular relevance in outsourcing and carve‑out transactions, where the economic‑entity boundary can be contested.

The BAG has also held that deficient employee information under §613a(5) BGB prevents the one‑month objection period from starting to run, meaning employees can object years after the purported transfer, a risk that can unravel a completed deal. Industry observers expect this line of case law to remain a live risk factor throughout 2026, particularly in cross‑border transactions where the information notice may be drafted under foreign‑law assumptions that do not meet German requirements.

Share Deals vs Asset Deals: When Employees Transfer in Cross‑Border M&A

The distinction between a share deal and an asset deal is the single most consequential structural choice for employment‑law purposes in German M&A. Understanding when and how a Betriebsübergang is triggered, or not, is essential for any cross‑border M&A lawyers Germany team advising on deal structure.

Asset Deal Checklist

An asset deal, the purchase of individual assets, contracts, business lines or an entire operation, will almost always trigger a Betriebsübergang under §613a BGB if the assets purchased constitute an economic entity that retains its identity in the hands of the buyer. The practical indicators to assess include:

• Workforce continuity. Will the buyer employ the same or a majority of the workforce performing the same functions?
• Tangible and intangible assets. Are machinery, premises, IP rights, customer databases or goodwill part of the sale?
• Customer and contract transfer. Will key customer relationships and supply contracts continue?
• Operational continuity. Is there minimal or no interruption in business activity?

If these factors are present, the employment relationships transfer automatically by operation of law, the buyer cannot cherry‑pick employees and has no right to refuse the transfer.

Share Deal Pitfalls

In a standard share deal, the employer entity (the target company) does not change, only its shareholders do. Consequently, a share deal does not trigger a Betriebsübergang. Employment relationships remain undisturbed within the same legal entity. However, two common pitfalls can still create employment‑law exposure:

• Post‑closing restructuring. If the buyer integrates the target’s operations into its own structure, merging business units, transferring production to another group entity or outsourcing functions, a secondary Betriebsübergang may be triggered at that stage.
• Tax‑driven carve‑outs. Proposed REtt changes in 2026 continue to make share‑deal tax structuring fluid. Where a buyer restructures asset ownership to manage REtt exposure, the resulting internal asset movements may inadvertently trigger employee transfer obligations. Co‑ordinating tax and labour advice at the structuring stage is critical.

Works‑Council (Betriebsrat) Obligations in Cross‑Border M&A

The works council is one of the most powerful stakeholders in any German transaction. Ignoring or underestimating its rights is the single most common compliance failure in cross‑border deals, and the consequences range from injunctions delaying closing to conciliation‑board awards imposing multi‑million‑euro social plans.

Mandatory Notice Content

Under §111 BetrVG, any employer with more than 20 employees that plans an operational change (Betriebsänderung), including reductions of workforce, closure or transfer of operations, mergers, material changes to work organisation or introduction of fundamentally new work methods, must inform the works council in full and in good time. The information must be sufficient for the works council to understand the planned change and assess its effects on employees. In M&A transactions, this means providing details on:

• Identity of the acquirer and the rationale for the transaction.
• Planned organisational changes, any post‑closing restructuring, headcount adjustments, relocation of functions or changes to reporting lines.
• Timeline, anticipated closing date and implementation schedule.
• Employee impact, which positions are affected, anticipated redundancies, and any retraining or redeployment measures.

Works‑Council Negotiation: Social Plan Mechanics

Where an operational change is planned, the employer must attempt to negotiate a reconciliation of interests (Interessenausgleich) and a social plan (Sozialplan) with the works council. The Interessenausgleich addresses whether and how the change will be implemented. The Sozialplan addresses compensation for employees who suffer economic disadvantages, typically severance payments, extended notice periods, outplacement services and pension top‑ups.

If the parties cannot agree, either side may invoke the conciliation board (Einigungsstelle) under §112 BetrVG. The conciliation board’s award on the social plan is binding and enforceable. A reconciliation of interests, by contrast, cannot be imposed, but the employer’s failure to attempt one in good faith can lead to claims for a so‑called Nachteilsausgleich (disadvantage compensation) under §113 BetrVG, which the labour court assesses at its discretion.

Redundancies, Restructuring and Social Plans Under German Redundancy Law

Post‑acquisition restructuring frequently requires headcount reductions. German redundancy law imposes both individual and collective safeguards that buyers must navigate carefully. Failure to comply renders dismissals void, and can expose the buyer to reinstatement claims, back‑pay and reputational damage.

Collective Redundancies vs Operational Terminations

The Kündigungsschutzgesetz (KSchG) protects individual employees against socially unjustified dismissal. In addition, where the number of planned dismissals within 30 calendar days exceeds statutory thresholds, the employer must file a collective redundancy notification (Massenentlassungsanzeige) with the Federal Employment Agency (Agentur für Arbeit). The thresholds depend on establishment size:

• Establishments with 21–59 employees: more than 5 dismissals.
• Establishments with 60–499 employees: 10% of the workforce or more than 25 dismissals.
• Establishments with 500+ employees: at least 30 dismissals.

The notification must be filed before dismissal notices are issued. Once filed, a blocking period (Sperrfrist) of at least one month applies, during which dismissals may not take effect. Failure to notify or premature issuance of dismissal notices renders those dismissals void, a risk the BAG has repeatedly enforced.

In addition, the works council must be consulted under §102 BetrVG before every individual dismissal. The employer must provide the reasons for dismissal and the social selection criteria applied. If the works council is not heard, the dismissal is automatically void regardless of its substantive justification.

Designing an Enforceable Social Plan

A well‑structured social plan is both a legal obligation and a strategic tool. It provides certainty to the buyer on the maximum cost of workforce reduction and mitigates litigation risk by incentivising employees to accept severance rather than challenge dismissals. The typical components of a German social plan include:

The one‑year protection period under §613a(1) sentence 2 BGB does not prohibit redundancies, but any dismissal must be justified on operational grounds unrelated to the transfer itself. Industry observers expect labour courts to scrutinise post‑transfer restructuring plans carefully, particularly where dismissals occur within the first twelve months after a Betriebsübergang.

M&A Due Diligence: Employment Liabilities Checklist

Employment due diligence in German cross‑border M&A is not a box‑ticking exercise, it determines whether the price is right and whether the deal structure works. The following checklist sets out the minimum scope for any M&A due diligence involving German operations:

• Complete employee register. Headcount by entity, location, employment type (permanent, fixed‑term, temporary agency workers, freelancers), seniority and salary bands.
• Works‑council status. Existence and composition of Betriebsrat, Gesamtbetriebsrat or European works council; current or pending reconciliation‑of‑interests or social‑plan negotiations.
• Collective agreements. Applicable collective bargaining agreements (Tarifverträge) and works agreements (Betriebsvereinbarungen); terms that survive a Betriebsübergang.
• Pending litigation and claims. Employment tribunal proceedings, unfair dismissal claims, equal‑pay actions, whistleblower complaints.
• Pension and benefit obligations. Direct pension commitments (Direktzusagen), pension fund exposure, deferred compensation schemes, long‑service awards.
• Contingent liabilities. Outstanding holiday and overtime balances, bonus accruals, retention arrangements, change‑of‑control clauses in executive contracts.
• Compliance status. GDPR employee‑data processing; occupational health and safety obligations; immigration‑law compliance for non‑EU workers.
• EU Pay Transparency readiness. Salary‑band documentation, gender pay‑gap data and reporting preparedness ahead of the 7 June 2026 transposition deadline.

SPA Drafting: Allocating Employment Liabilities, Indemnities and Warranties

The share purchase agreement or asset purchase agreement is where employment‑law risk is allocated between buyer and seller. In cross‑border deals, SPA employment provisions are often drafted under English or US‑law conventions that do not map cleanly onto German mandatory law. Specialist cross‑border M&A lawyers in Germany should review every employment clause for enforceability under German law.

Sample SPA Clauses (Illustrative, Non‑Binding)

Practitioner note: The following clause excerpts illustrate common drafting approaches. They are for guidance purposes only and must be adapted to the specific transaction.

Employee transfer warranty:

“The Seller warrants that (i) Schedule [X] contains a complete and accurate list of all employees of the Business as at the date of this Agreement, (ii) there are no pending or threatened employment claims, proceedings or grievances relating to any employee, and (iii) all obligations arising under §613a BGB in connection with prior transfers of employees have been fully discharged.”

Pre‑closing liability indemnity:

“The Seller shall indemnify and hold harmless the Buyer against all Employment Losses arising from or relating to (a) any act, omission or event occurring prior to Closing, (b) any deficiency in the employee information notices provided under §613a(5) BGB, and (c) any social plan or Nachteilsausgleich claim attributable to measures planned or initiated by the Seller prior to Closing.”

Social plan escrow:

“An amount equal to EUR [●] (the ‘Social Plan Escrow Amount’) shall be deposited into the Escrow Account at Closing to secure the Buyer’s potential exposure to social plan negotiations arising from the Post‑Closing Restructuring Plan. The Escrow Amount shall be released to the Buyer upon final settlement of all social plan claims, or to the Seller to the extent not utilised within [24] months of Closing.”

Additional SPA provisions that experienced deal teams include are: caps and baskets calibrated to realistic social‑plan cost estimates; survival periods for employment warranties extending beyond the standard 18–24 months (to cover late employee objections under §613a); covenants requiring the seller to co‑operate in works‑council consultations prior to closing; and MAC clauses that specifically reference material social‑plan obligations as a closing condition.

Practical Negotiation Tactics, Timelines and Case Studies

Experienced practitioners structure works‑council engagement in parallel with transaction timelines rather than sequentially. The recommended approach involves initiating informal dialogue with the Betriebsrat as soon as signing is reasonably certain, providing a draft information package that meets §111 BetrVG standards, and building a social plan budget into the financial model from the outset. In one anonymised mid‑market cross‑border transaction, a buyer’s failure to engage the works council until after signing led to a four‑month delay in closing and a conciliation‑board award that exceeded the original social‑plan budget by 40%. Early engagement, particularly through a trusted German employment‑law adviser, consistently produces better outcomes in terms of both cost and timeline.

Conclusion and Recommended Next Steps

German employment law creates a mandatory compliance framework that no cross‑border M&A transaction can afford to treat as an afterthought. The convergence of BRUBEG, the Pay Transparency Directive transposition deadline and evolving REtt proposals in 2026 makes specialist labour‑law input at the structuring, due diligence and SPA drafting stages more critical than ever. Deal teams should confirm Betriebsübergang exposure at the outset, engage the works council early, budget for social plan costs and ensure that the SPA allocates employment liabilities with enforceable precision. Engaging specialist cross‑border M&A lawyers in Germany with deep expertise in both employment law and transactional practice is the most effective way to protect deal value and avoid post‑closing surprises.
