Works council agreements in Germany need a valid resolution

High financial risk for businesses: works agreements need a verifiable resolution, a signature alone is not sufficient
At a glance
Germany's Federal Labour Court has ruled that works agreements without a properly documented council resolution are, in principle, invalid.
Employers face potentially significant financial exposure where existing agreements cannot be shown to rest on a valid resolution.
Affected businesses may wish to review their works agreements and take steps to regularise any gaps in the documented decision-making process.
The German Federal Labour Court, in its judgment of 27 January 2026, in case 1 AZR 147/24, has clarified that works agreements without a valid resolution by the works council are, in principle, invalid. Employers in Germany can no longer rely on the signature of the works council chairperson alone being sufficient. They must be able to prove that every works agreement is based on a resolution duly adopted by the works council. If they cannot, they face potentially significant legal and financial risks.
A collective decision by works council
The starting point of the decision is the legal nature of the works council as a collegial body. The works council forms its will collectively, through resolutions passed by the council, not through unilateral actions of individual members. The chairperson therefore only represents the works council within the scope of resolutions that have been properly adopted.
Historic argument is irrelevant
If there is no underlying works council resolution, a signed works agreement does not come into existence with legal effect. The court emphasises that reliance on the chairperson’s signature cannot replace the democratic legitimisation by the entire body. Claims such as “we have always done it this way” and “the works council never challenged it” carry no legal weight.
Even a practice that has been followed for years on the basis of an invalid works agreement does not cure this defect; neither apparent authority (Anscheinsvollmacht) nor tolerance authority (Duldungsvollmacht) can compensate for the absence of a valid resolution.
Proactive legal check by labour courts
The Federal Labour Court also provides important procedural clarification: German courts must, of their own motion, ascertain the provisions of collective bargaining law contained in works agreements under section 293 of the Code of Civil Procedure (ZPO). Depending on the parties’ submissions, this duty includes examining the validity of those provisions. Under the ZPO, examination of their own motion means that the court independently ascertains the relevant collective bargaining provisions and is not, as in the case of ordinary questions of fact, bound solely by the parties’ submissions. This increases the risk that defects in validity will be uncovered even if no party expressly raises them.
Substantial financial exposure
The case underlying the decision vividly illustrates the financial implications that a lack of careful documentation of works council resolutions and an absence of alignment between the content of the resolution and the signed text can have for companies. An employee argued that a subsequent works agreement on the company pension scheme was invalid. As the required works council resolution could not be proven, the agreement was held to be invalid; an earlier, more favourable pension commitment remained in force. The employer is now required to pay the claimant a company pension that is approximately €422 higher per month for the rest of his life. Multiplied across all eligible employees, the financial exposure for employers can rapidly mount to millions of euros.
The principles established by the Federal Labour Court have implications beyond this individual case. They apply not only to future works agreements but also to those already concluded – in particular, those with significant financial implications, including agreements relating to pay, working hours and occupational pension schemes.
Osborne Clarke comment
For employers operating in Germany or running businesses there, this ruling clearly demonstrates that careful preparation and documentation are essential when concluding works agreements.
For every new works agreement, employers should ensure they are provided with clear evidence of the underlying works council resolution.
Existing works agreements, particularly those with significant financial implications and unclear decision-making processes. should be reviewed to ensure that the relevant works council resolutions have been properly documented.
Where doubts remain, having the works council pass a new, properly authorised resolution and then sign the agreement may be the safest way to minimise legal and economic risks. Alternatively, the retrospective approval of flawed or ambiguously documented resolutions is worth checking. The works council can clarify, by means of a formal confirmation resolution, that the specific works agreement was approved by the body and that the chairperson was authorised to sign it.
By doing so, both doubts as to representation and formal uncertainties can be effectively resolved, and the agreement can be placed on a sound legal footing.
