Mercedes-Benz Workers Protest 40-Hour Week Plan Across German Plants

Introduction

Thousands of Mercedes-Benz employees across several German production sites took to the streets in mass protests against the company's cost-cutting agenda. The most contentious element of management's plans is a proposal to increase the working week from 35 to 40 hours — a move that workers and their union representatives say amounts to a pay cut in all but name. For expats working in Germany, especially those in manufacturing, automotive or industries covered by collective agreements, this dispute is a reminder of how strongly protected — and actively defended — workers' rights are in this country.

What Mercedes-Benz Is Planning

Facing significant financial pressure, Mercedes-Benz management has put forward a package of cost-reduction measures. The headline proposal is extending the standard working week from 35 hours to 40 hours for workers currently covered by the metalworkers' collective agreement (Tarifvertrag), which is negotiated by the powerful IG Metall union.

The 35-hour week has been a cornerstone of German industrial labour relations since the 1980s, won through years of union action. Critics of the Mercedes proposal argue that asking employees to work five additional hours per week — without a corresponding increase in weekly pay — is effectively a 12.5% pay cut in hourly terms. Management frames it as a necessary step to remain competitive in a rapidly changing automotive market facing pressure from electric vehicle competition and slowing demand.

Worker and Union Response

The protests were large and organised across multiple sites, a sign that the opposition is not limited to one factory or region. IG Metall, which represents the majority of Mercedes-Benz's German workforce, has been vocal in its opposition to the working hours plan.

Union representatives argue that the company should find savings elsewhere — through management structures, procurement, or investment strategy — rather than placing the burden on shop-floor workers. Worker councils (Betriebsräte), which have significant legal rights in Germany, are also expected to resist the proposals through formal channels, as any change to working conditions of this scale requires their agreement under German co-determination law (Mitbestimmung).

The protests signal that even if management pushes ahead, this will be a long negotiation process rather than a quick change.

What This Means for Germany's Labour Market

The Mercedes-Benz dispute is not happening in isolation. Germany's automotive sector is under severe structural pressure, and several major employers — including Volkswagen — have been engaged in similar battles with unions over costs, working hours and job security in recent months.

For Germany's wider labour market, the outcome of high-profile disputes like this one sets a precedent. If a company the size of Mercedes-Benz succeeds in extending working hours without proportional pay increases, other employers in different sectors may attempt similar moves. Conversely, if the union and works council block or significantly alter the plan, it reinforces the strength of Germany's co-determination framework.

Germany's employment rate remains relatively high, but the economy has been in or near recession territory, and corporate cost-cutting pressure is real across many industries where expats work.

What Expat Workers in Germany Should Know

If you work in Germany under a collective agreement — which covers a large share of jobs in manufacturing, healthcare, retail and public services — your working hours and pay conditions are protected by that agreement and cannot simply be changed by your employer unilaterally. Your Betriebsrat (works council) must be consulted on significant changes to working conditions.

If you are employed outside a collective agreement (for example, on an individual contract in the tech sector), your working hours are governed by your contract and Germany's Working Hours Act (Arbeitszeitgesetz), which caps regular working time at eight hours per day (extendable to ten under certain conditions).

For expats considering jobs in the automotive sector or other traditional German industries, understanding whether a role is covered by a Tarifvertrag is an important part of evaluating a job offer — it affects not just pay, but holidays, notice periods and exactly situations like this one.

Frequently Asked Questions

Can my German employer just increase my working hours without asking me?

No. Changes to your working hours must be reflected in your employment contract and, where applicable, agreed through your Betriebsrat. Under German law, unilateral changes to core contractual terms — such as hours — are not permitted. If your employer pressures you to work more hours without a formal contract amendment, seek advice from your union or a labour lawyer.

Does the 35-hour week apply to all workers in Germany?

No — the 35-hour week is not a universal legal standard in Germany. It applies specifically to workers covered by certain collective agreements, most notably in the metalworking and electrical industries under IG Metall contracts. The statutory maximum is eight hours per day, six days per week, under the Arbeitszeitgesetz. Your actual contracted hours depend on your individual contract and any applicable Tarifvertrag.

Conclusion and Next Steps

The Mercedes-Benz dispute is a live situation, and the outcome will take weeks or months to resolve through formal negotiations between management, IG Metall and the Betriebsrat. For expats in the automotive sector or covered by similar collective agreements, it is worth understanding your own contract's working time terms and knowing that your works council has real legal power to protect them.

If you are unsure whether a Tarifvertrag applies to your job, ask your HR department or check with your union. Deutschland4U will continue to follow this story as it develops.
