Codetermination: How Half a Supervisory Board Changes Every Decision

Codetermination is the single most misunderstood feature of German corporate governance, and it explains outcomes that look inexplicable from outside. Why Volkswagen could not close a plant, why restructuring programmes take five years, and why German industrial conflict is rarer than the labour representation would suggest, all follow from the same structure. This case study opens the governance pillar of the Germany Company Stories hub.

How does the structure actually work?

German public companies have two boards. A management board runs the business day to day. A supervisory board appoints and dismisses the management board, approves major transactions and monitors performance, and it is where employee representatives sit.

The composition depends on size. Companies with more than five hundred employees have one third employee representation; those above two thousand have parity, with half the seats held by employees and union representatives.

Under parity, deadlock is resolved by the chair, who is elected by shareholders and holds a second vote. That is the formal mechanism preserving shareholder primacy, and it is used sparingly because using it signals a breakdown.

The practical effect is that management arrives at supervisory board meetings having already negotiated with labour representatives, because a proposal that requires a casting vote is a proposal that will be resisted throughout its implementation.

What can employee representatives actually block?

Not much formally, and a great deal practically. The supervisory board approves major transactions, capital measures and the appointment of executives, and employee representatives can vote against all of them without prevailing if the chair uses the casting vote.

Where the influence becomes decisive is in decisions that require ongoing cooperation. A plant closure requires a reconciliation of interests agreement with the works council covering social plan payments, transfers and timing, and negotiating that from a position of open conflict extends the process by years.

Appointment of the management board is the other lever. Employee representatives voting as a bloc against a candidate creates a public signal that the executive lacks internal support, which usually prevents the appointment before a formal vote occurs.

The combination explains the pattern visible in the Volkswagen restructuring: management proceeded with capacity and model decisions within its authority while a plant closure proposal was rejected by the board.

Why does codetermination reduce industrial conflict?

Because it converts disputes into negotiations before they become public. Employee representatives receive financial and strategic information as board members, which means they understand the commercial case for a restructuring rather than encountering it as an announcement.

That information access is the mechanism. A representative who has seen the utilisation figures and the market forecasts can explain to the workforce why a reduction is necessary, and can negotiate its terms rather than opposing its existence.

The empirical outcome is that Germany loses far fewer working days to industrial action than comparable economies, despite very high union influence in large companies.

The trade is speed. Every major decision requires an information and consultation process that takes months, and management teams accustomed to faster jurisdictions consistently underestimate the timeline, which is the most common execution failure in cross-border acquisitions of German companies.

Does it hurt or help company performance?

The research is genuinely mixed and the effects appear to differ by context. Studies have found positive associations with investment, training and long-term orientation, and negative associations with speed of adjustment in declining industries.

The mechanism for the positive findings is horizon. Employee representatives have a longer effective tenure than most executives and a strong interest in the company existing in twenty years, which pushes against short-term measures that damage capability.

The mechanism for the negative findings is the same feature viewed from the other side. Where an industry is in structural decline, the socially optimal response is faster contraction, and a governance structure designed to protect employment delays it.

The honest summary is that codetermination improves outcomes in growing and stable industries and worsens them in declining ones, which is precisely why the current German industrial restructuring is where the system faces its hardest test.

How do foreign owners handle it?

Badly at first and then adequately. The common error is treating employee board representatives as an obstacle to be circumvented, which produces exactly the resistance it fears.

The approach that works is early, genuine information sharing with the representatives, including commercially sensitive material, well before any decision requires approval. Representatives who learn of a plan from the press oppose it regardless of merit.

The second practice is to negotiate the social framework, employment guarantees, site commitments, voluntary mechanisms, before announcing the commercial rationale, so the announcement includes the answer to the question everyone will ask.

Some foreign owners avoid the structure entirely through legal form, using a European company structure or a partnership limited by shares, which can preserve a smaller board or a different composition. Those routes are legitimate, increasingly scrutinised, and they do not remove works council rights at plant level.

What is the works council and how does it differ?

A separate institution operating at establishment level rather than at board level, elected by the workforce regardless of union membership, with statutory rights over a defined list of matters.

The rights are graded. On some matters the council must be informed; on others consulted; and on a specific list, including working hours, shift patterns, overtime, holiday scheduling, performance monitoring and workplace rules, it holds genuine co-determination, meaning the employer cannot act without agreement.

That last category is where operational friction actually occurs. Introducing a new shift pattern, a productivity monitoring system or a change to working time requires agreement, and disagreement goes to a conciliation body whose decision binds both parties.

For restructuring, the council's rights cover the reconciliation of interests, the negotiation over whether and how a change happens, and the social plan, the compensation for employees affected. The first can be delayed; the second must be agreed or arbitrated.

Does codetermination apply to foreign-owned companies?

Yes, based on where employees work rather than on who owns the company. A German subsidiary of a foreign group with more than two thousand employees in Germany is subject to parity codetermination in that subsidiary.

This surprises acquirers regularly. Buying a German company does not buy the right to manage it the way a company in the acquirer's home jurisdiction is managed, and the governance obligations attach to the acquired entity.

Some structures reduce the exposure. A European company form can freeze board composition at the level existing when it was established, and holding structures can affect which entity crosses the thresholds. These are legitimate and increasingly examined by courts and regulators.

None of them removes works council rights, which attach to the establishment and cannot be structured away, which is why the plant-level relationship matters more than the board composition for day-to-day operations.

How does it affect executive pay and transparency?

Substantially. Employee representatives sit on the committee setting management board compensation, which introduces direct internal comparison between executive pay and workforce pay into the decision itself.

The effect is visible in outcomes. German executive compensation at large companies has consistently been lower than American equivalents at similar scale, with a smaller equity component and more emphasis on multi-year operational targets.

The secondary effect is disclosure discipline. Compensation systems that must be explained to employee representatives and approved by shareholders tend to be simpler and more clearly linked to results, because complexity invites challenge from a constituency that will publicise it.

What happens during an insolvency?

The works council retains its rights and gains additional protections, and employee claims receive preferential treatment for a defined period through a state-funded insolvency payment scheme covering wages.

German insolvency law includes a self-administration procedure allowing existing management to continue running the business under supervision while restructuring, which preserves operations and requires cooperation with employee representatives.

For a distressed company the practical consequence is that a restructuring negotiated with the works council in advance of insolvency is far cheaper and faster than one attempted afterwards, which is why early engagement matters most precisely when management least wants to disclose difficulty.

What should a manager actually do differently?

Treat the works council as a standing counterparty rather than as a problem that arises during restructuring. Councils that receive routine information and are consulted on ordinary matters respond very differently to a difficult proposal than councils that hear from management only in a crisis.

The second practice is timing. Statutory consultation periods run from formal notification, so informal discussion before notification costs nothing procedurally and builds the understanding that makes the formal process shorter.

The third is to separate what is negotiable from what is not, and to say so. A management team presenting a decision as consultative when it is already fixed loses credibility permanently, and councils respond better to an honest statement that a change is necessary and that its terms are open.

Taken together, these practices explain why some foreign-owned German subsidiaries restructure smoothly while others spend years in conflict over comparable measures. The difference is almost never the commercial case; it is whether the relationship existed before it was needed.

One further practical note for CFOs: the cost of a negotiated social plan should be provisioned early and disclosed clearly, because the negotiation itself is shaped by what the counterparty believes the company can afford, and a provision that appears only after agreement invites the suspicion that more was available.
