Codetermination is a legal framework that gives employees formal power over how their company is run, on two levels: elected worker representatives sit on the corporate supervisory board alongside shareholder representatives, and elected works councils hold binding authority over workplace conditions like scheduling, monitoring, and dismissals. Germany operates the most developed version, but well over a dozen European countries have their own systems. The United States does not.
The Two Levels of Codetermination
Codetermination works because it splits corporate power into two arenas and gives workers a seat in each.
The first arena is the boardroom. German corporate governance uses a two-tier structure: a Management Board runs the business day to day, and a separate Supervisory Board monitors management, reviews strategy, and appoints or removes the executives who actually run the company.1Business.gov.nl. One-Tier or Two-Tier Board as a Governance Model Employee representatives sit on the Supervisory Board. They don’t manage anything. They vote on who does, and on the big strategic and financial questions that come before that board. The leverage is real: the power to hire and fire the CEO is shared with people elected by the workforce.
The second arena is the shop floor. Works councils are elected employee bodies, legally separate from both trade unions and the Supervisory Board, that govern the conditions employees actually live under. Their remit is workplace rules, not corporate strategy. Together, the two levels form what German law calls codetermination: strategic voice at the top, binding co-decision on daily conditions below.
When Board Representation Is Required in Germany
Company size decides how much boardroom representation employees get. Two statutes set the thresholds.
The One-Third Participation Act of 2004 covers stock corporations, limited liability companies, partnerships limited by shares, mutual insurance companies, and cooperatives that normally employ more than 500 people. These companies must reserve one-third of their Supervisory Board seats for worker representatives.2Federal Ministry of Justice and Consumer Protection. One-Third Participation Act (DrittelbG) The reach is broader than many people expect, catching cooperatives and mutual insurers along with the more familiar corporate forms.
Once a company crosses 2,000 employees, the Codetermination Act of 1976 takes over. Half of the Supervisory Board seats go to employee representatives.3Worker Participation. Act on the Co-determination of Employees (MitbestG) This is called parity codetermination because labor holds the same number of seats as shareholders. The balance tilts slightly toward capital through one mechanism: when the board deadlocks, the chairperson casts the deciding vote, and if the board cannot agree on a chairperson, the shareholder side elects one from among its own.4European Corporate Governance Institute. Codetermination – A Poor Fit for U.S. Corporations
Companies that fail to constitute their boards correctly face structural rather than monetary penalties. An election that violates rules on voting rights, eligibility, or procedure can be contested in labor court and declared invalid, and unfilled seats must then be filled by court appointment or by-election. Board resolutions passed without proper employee representation are vulnerable to legal challenge, which is a strong compliance incentive on its own.3Worker Participation. Act on the Co-determination of Employees (MitbestG)
How Employee Board Members Are Elected
Worker representatives reach the Supervisory Board through statutory elections by secret ballot. All permanent employees who meet minimum age and tenure requirements can vote. Trade unions play a formal role in nominating candidates, and under the 1976 Act one of the employee-side seats is typically reserved for a union representative who may not even work at the company.
Smaller companies under the One-Third Participation Act use direct elections. Larger companies under the 1976 Act often use a delegate system: workers in different plants or regions first elect delegates, who then cast the final votes for board members. Once seated, employee representatives hold the same legal rights and duties as their shareholder-elected counterparts. They owe a duty of care to the company as a whole, not only to the workers who elected them, but they bring a labor perspective the boardroom would otherwise lack.
Works Councils and Daily Workplace Authority
Board representation shapes strategy. Works councils shape everything else. Under Germany’s Works Constitution Act, works councils hold binding co-determination rights over a defined list of workplace matters, meaning the employer cannot make unilateral changes without the council’s agreement:
- Working hours and breaks, including start and end of daily shifts, distribution of hours across the week, and any temporary extension or reduction of hours5Gesetze im Internet. Works Constitution Act (Betriebsverfassungsgesetz) – Section 87
- Technical devices designed to monitor employee behavior or performance, including software surveillance
- Principles of remuneration, bonus rates, and new compensation methods
- Measures for preventing workplace accidents and occupational diseases
- General principles for vacation planning and the timing of individual leave
- Internal policies governing employee conduct
- The structuring of mobile work performed through information and communication technology
The monitoring provision has become one of the most consequential. Any time a German employer wants to deploy software that tracks keystrokes, monitors email, measures productivity through screen time, or uses GPS to follow company vehicles, the works council must agree first.6National Protective Security Authority. Employee IT Monitoring in Germany Employees in most other countries have no equivalent veto.
When the works council and employer cannot agree on a co-determination matter, the dispute goes to a conciliation committee made up of equal numbers of employer and council representatives plus a neutral chairperson. If the two sides cannot agree on the chair, a labor court appoints one. On mandatory co-determination topics, the committee decides by majority vote and its decision is binding, replacing the agreement the parties could not reach.7Gesetze im Internet. Works Constitution Act (Betriebsverfassungsgesetz) – Section 76
Companies with more than 100 permanent employees must also establish a finance committee that receives detailed information about the company’s economic situation, production and investment programs, rationalization plans, potential closures, and takeover bids, and reports back to the works council.8Gesetze im Internet. Works Constitution Act (Betriebsverfassungsgesetz) – Section 106 Workers rarely get blindsided by major restructuring.
Dismissals and Hiring
The sharpest works council power is over individual personnel decisions. The council must be consulted before every dismissal, and any termination notice given without that consultation is automatically void.9Gesetze im Internet. Works Constitution Act (Betriebsverfassungsgesetz) – Section 102 Not voidable, not curable after the fact. Null. The employer must state the reasons and give the council time to respond.
For hires and internal transfers, the council holds consultation rights rather than a veto. Management must notify the council and hear objections before proceeding. Where an employer repeatedly bypasses the council on matters requiring mandatory consultation, a labor court can issue an injunction.
Codetermination Is Not Collective Bargaining
The two are often confused, and the distinction matters. Collective bargaining is a negotiation between an employer and a union over wages, benefits, and working conditions. Codetermination is a legal right to participate in the governance of the firm itself. A union negotiates a contract. A codetermination representative votes on whether to fire the CEO.
Germany runs a dual-channel system. Industry-level unions negotiate wages through collective bargaining agreements, while legally separate works councils handle workplace co-determination. A works council can engage in local wage bargaining only where the industry-level agreement expressly allows it. The union sets the floor; the works council fine-tunes local conditions. Sweden and Norway do it differently, using a single-channel system where establishment-level union representatives fill both roles, though the authority to bargain over pay still flows from the union role rather than from codetermination law.
Codetermination Outside Germany
Germany is the most far-reaching example, not the only one. The Scandinavian countries require board representation at much lower employee counts. Sweden gives workers at companies with as few as 25 employees two board seats, rising to three at companies with more than 1,000. Norway starts at 30 employees and scales up to one-third of the board plus an additional seat above 200 workers. Denmark requires at least one-third employee representation in companies with more than 35 employees, if a majority of the workforce votes in favor. Scandinavian workers typically top out at around one-third of seats, never the near-parity Germany requires above 2,000 employees.
Austria requires one-third employee representation on the supervisory boards of limited companies with at least 300 employees, and has no minimum threshold at all for public limited companies. France requires one or two employee board members at private companies with 1,000 or more domestic employees. The Netherlands allows up to one-third representation from 100 employees onward. Slovakia and Slovenia mandate between one-third and one-half depending on company structure.10European Parliament. Works Councils – Workplace Representation and Participation Structures
The United States Has No Codetermination
American law does not require employee board representation, and two features of the legal landscape actively resist creating it. Section 8(a)(2) of the National Labor Relations Act makes it an unfair labor practice for an employer to “dominate or interfere with the formation or administration of any labor organization or contribute financial or other support to it.”11Office of the Law Revision Counsel. 29 U.S. Code 158 – Unfair Labor Practices The statutory definition of “labor organization” is broad enough that a German-style works council set up by a U.S. employer could be struck down as a company-dominated union. American corporate law adds a second barrier by treating management’s exclusive authority over business decisions as a core principle, a stance the Supreme Court reinforced in 1981 when it narrowed the scope of what unions could bargain over.
Congress has considered changing this. The Accountable Capitalism Act, most recently reintroduced in late 2024, would require corporations with more than $1 billion in annual revenue to obtain a federal charter obligating them to ensure that at least 40% of their directors are elected by employees.12U.S. Congress. S.5493 – Accountable Capitalism Act, 118th Congress (2023-2024) The Reward Work Act, introduced in 2020, was narrower: one-third employee-elected directors at publicly traded companies that received pandemic-related financial assistance and had repurchased more than $1 billion in stock over the prior five years.13GovTrack. S. 3540 (116th) – Reward Work Act Neither has advanced to a floor vote.
What the Evidence Shows
The practical question behind every codetermination debate is whether shared governance helps or hurts the companies subject to it. Economic research on Germany’s laws has found no measurable productivity disadvantage for codetermined firms compared to otherwise similar companies without employee board representation. The concern that worker influence leads to worse business decisions has not shown up in the data.
What the research does show is a distributional effect. Codetermination increases workers’ bargaining power by roughly 3.5% to 4.3%, which shifts a larger share of firm profits toward employees rather than shareholders. That is why the debate stays heated even when the productivity findings are neutral. Shareholders and executives who treat labor costs as a drag on returns see codetermination as an institutional thumb on the scale. Workers and labor advocates see it as a correction to an imbalance in which the people generating value have no vote on how it is divided. The disagreement is about what a corporation is for, not about whether the system works.
