German Law Blocks Employer’s Pay Cuts as ZF Workers Rebel Over Bonus Elimination

ZF Friedrichshafen workers protest plans to scrap bonuses worth up to €500 monthly. German labor law prevents unilateral pay changes without council consent.

A stormy employee assembly at automotive supplier ZF Friedrichshafen collapsed on Tuesday after workers jeered the company’s personnel chief, Lea Corzilius, forcing the works council to call off the event. The flashpoint: management’s plan to scrap two supplemental payments—the so-called “Zeppelin allowance” and a fixed performance bonus—with an 18?month notice period ending July 1, 2027.

The dispute underscores a bedrock principle of German labour law: employers cannot rewrite pay structures on their own. Under Section 87 of the Works Constitution Act (Betriebsverfassungsgesetz), works councils hold a mandatory co?determination right over remuneration principles and variable compensation systems. Any unilateral change by management is void without the council’s consent.

The Stakes for 7,500 Workers

The affected bonuses amount to 7?% to 13?% of base salary. Employee representatives calculate the hit at €300 to €500 a month for each of the roughly 7,500 staff members. The company is simultaneously planning to cut up to 14,000 jobs nationwide by the end of 2028, citing a net loss of €2.147?billion in 2025.

The works council has rejected management’s alternative: converting the fixed amounts into a performance?linked variable payment. Workers demand the allowances stay as they are.

Legal Backing from the Top Court

The Federal Labour Court (BAG) reinforced works councils’ clout in July 2024, ruling that unilateral performance targets set by employers are invalid without works council approval. Labour law experts note that any rule adopted without the required consent carries no legal force.

When the two sides cannot agree, the dispute goes to an arbitration board (Einigungsstelle). Recent data shows these proceedings are rising sharply. The employer foots the bill, and roughly 70?% of cases are resolved in the very first session.

A study from the University of Trier and Bielefeld University of Applied Sciences, published in May 2026, underlines the protective role of works councils. In workplaces without one, employees are three times more likely to earn less than the current minimum wage of €13.90 per hour.

Parallel Fronts: Public Sector, Working Hours, and Trade Talks

The pressure is not confined to the automotive sector. Business organisations are pushing for performance?based pay for civil servants. The SPD Economic Forum has called for a link between higher pay and faster bureaucracy reduction. The civil servants’ union (Beamtenbund) is wary of pure performance premiums but open to merit?based pay steps.

On working time, Chancellor Friedrich Merz has promised a draft law in autumn to allow weekly rather than daily maximum hours. Employers welcome the flexibility; unions have vowed to fight it.

In retail, wage talks stalled in four federal states on Tuesday. The Verdi union demands a 7?% raise; employers have offered just 3.5?% over a significantly longer contract period.

For the workers at ZF, the immediate question is whether the works council can force management to keep the bonuses—or whether the case will end up in the arbitration board, where German labour law’s balance of power meets its most practical test.
