Every EU member state has its own working time law. Germany's ArbZG, France's Code du travail, Spain's Estatuto de los Trabajadores, Italy's D.Lgs. 66/2003. Each is different in the details. But every one of them is downstream of the same source: Directive 2003/88/EC, known to lawyers as "the Working Time Directive" and to almost nobody else by its proper name.
This post explains what the directive actually requires, where member states have flexibility, what the most-cited cases say, and what an employer operating across multiple EU countries can rely on as the floor.

What a Directive Is, Briefly
EU directives are binding on member states as to the result, but each state implements them through its own laws. So the Working Time Directive sets minimum standards; national laws apply them and often go further. An employer in Germany follows the ArbZG, not the directive itself, but the ArbZG cannot fall below what the directive says.
This matters in two practical ways:
- Cross-border baselines. If you operate in three countries, you can use the directive as the floor; every country's law meets it or exceeds it.
- EU case law binds. European Court of Justice rulings on the directive bind all member states, even before they update their domestic law. The CCOO ruling of 2019 (covered in the dedicated post) is the best-known example.
The Five Pillars
1. Maximum Weekly Working Time
Article 6: Working time, including overtime, must not exceed 48 hours on average per seven-day period.
The average is computed over a "reference period" of up to four months, extendable to six (for specific sectors) or twelve (with collective agreement). So a 60-hour week is legal if balanced by lower weeks within the reference window.
2. Daily Rest
Article 3: A minimum of 11 consecutive hours of rest per 24-hour period.
This is the hard floor. The 13-hour-workday-plus-11-hour-rest math is the practical upper limit on a single day.
3. Weekly Rest
Article 5: A minimum of 24 consecutive hours of rest in every 7-day period, on top of the daily 11-hour rest. In practice, 35 hours of continuous rest per week.
4. Annual Paid Leave
Article 7: Every worker is entitled to at least four weeks of paid annual leave.
This entitlement cannot be replaced by an allowance in lieu, except on termination of the employment relationship. The European Court of Justice has consistently ruled (Schultz-Hoff, Bollacke, Max-Planck) that the right to paid leave is fundamental and cannot lapse without the employer notifying the worker of the deadline.
5. Night Work
Article 8: Normal hours of work for night workers cannot exceed an average of 8 hours in any 24-hour period.
Member states define "night worker" specifically. The directive sets the night period at 7 consecutive hours including the period from midnight to 5 AM.
Breaks and Adolescent Workers
Article 4: Workers are entitled to a rest break when the working day is longer than 6 hours. Details (length, paid or unpaid) are left to member states. Germany requires 30 minutes after 6 hours; the UK before Brexit required 20 minutes.
Young workers (Directive 94/33/EC): Protection of workers under 18 is governed by the separate Young Workers Directive 94/33/EC, not the Working Time Directive. Most countries cap young workers at 8 hours a day and 40 hours a week, with mandatory 30-minute breaks after 4.5 hours.
The Opt-Out
Article 22: Member states can opt out of the 48-hour weekly cap for individual workers, provided certain safeguards are in place. The United Kingdom famously used this opt-out heavily during EU membership; Ireland, Malta, and Cyprus also use it on a limited basis.
Conditions for valid opt-outs:
- The worker's consent must be explicit and in writing
- The worker can withdraw consent (usually with 3 months notice)
- No detriment for refusing
- Records of opt-out workers must be kept and made available to inspectors
Most continental member states (Germany, France, Italy, Spain) have not used the opt-out in any meaningful way.
Excluded Sectors
The directive does not apply uniformly to every sector. Article 17 allows derogations for:
- Senior executives with autonomous decision-making power
- Family workers
- Religious workers
- Specific transport workers (covered by sector-specific rules)
Most importantly, the directive does not apply uniformly to mobile workers in road transport (covered by EC Regulation 561/2006) or seafarers (covered by the Maritime Labour Convention). Offshore oil and gas workers fall under special provisions of the Working Time Directive itself, introduced by the amending Directive 2000/34/EC, rather than a separate offshore directive.
How the CCOO Ruling Changed the Game
In 2019, the European Court of Justice ruled in Case C-55/18 (CCOO vs Deutsche Bank SAE) that the directive requires member states to oblige employers to set up an "objective, reliable and accessible" system of measuring daily working time. The court reasoned that without such a system, the rights guaranteed by the directive (the 48-hour cap, the 11-hour rest, the 24-hour weekly rest) cannot be verified.
The ruling does not specify what the system must look like. It says only that it must measure each worker's daily working time. Spain implemented the ruling almost immediately with Royal Decree-Law 8/2019. Germany did so via the BAG ruling of September 2022. Most other countries are still in some stage of catch-up.
For the full ruling and its implications, see the dedicated post on CCOO.
Reference Periods: How Averaging Works
The 48-hour cap is an average, not an absolute. The reference period determines how the average is computed:
| Worker category | Default | With collective agreement |
|---|---|---|
| Standard | 4 months | Up to 12 months |
| Certain transport | 6 months | Up to 12 months |
| Health, security | 6 months | Up to 12 months |
In practice this means an employer can roll a 12-month average if a collective agreement allows. Under such an arrangement, peaks of 60 or 70 hours in a single week are legal as long as the year ends inside 48 hours per week on average.
What Employers Operating in Multiple EU Countries Actually Do
Three patterns dominate among employers we see:
Pattern 1: Country-by-Country Compliance
Each country office runs against its own national law. The directive is the safety net, not the operational rulebook. Most common for established multinationals.
Pattern 2: Floor of the Directive Plus Tightest Country
Pick the tightest country in which you operate (often Germany or France) and apply its rules everywhere. Simplifies HR but can be more conservative than legally required.
Pattern 3: Single Pan-European Policy
A single policy that meets the directive, supplemented by country-specific exceptions. Works for organizations with strong shared culture, especially professional services and consulting.
A time tracking system that supports per-employee contracts with country-specific Working Time Rules (see the HR warnings post) covers all three patterns.
What "Working Time" Includes
The directive defines working time in Article 2(1):
"Working time means any period during which the worker is working, at the employer's disposal and carrying out his activity or duties, in accordance with national laws and/or practice."
The ECJ has expanded this in several rulings:
- SIMAP (C-303/98) and Jaeger (C-151/02): On-call duty performed at the workplace counts as working time, even when nothing happens.
- Matzak (C-518/15): On-call duty at home that significantly restricts the worker's freedom counts as working time.
- Tyco (C-266/14): Travel time between home and the first customer (and from the last customer to home), for workers without a fixed workplace, counts as working time.
The Tyco ruling is the most often overlooked. Mobile field workers, traveling salespeople, and visiting nurses all count their first-trip and last-trip travel as working time under EU law.
Common Questions
Does the directive apply to the self-employed? No. The directive covers workers under an employment relationship. Genuine self-employment falls outside.
Does the directive bind the UK after Brexit? The Working Time Regulations 1998 (the UK's implementation) remain in force. The UK is no longer bound by the directive itself, but the WTR continues to apply as domestic law. Future changes are at Westminster's discretion.
What about EU candidate countries? Candidate countries (e.g., Albania, North Macedonia, Serbia) must align with the directive as part of the accession process. Their domestic law is typically already compliant or near-compliant.
Can I require employees to work more than 48 hours? Only with a valid opt-out under Article 22 (mostly limited to UK and Ireland) and only with explicit, retractable employee consent. In most of the EU, the cap is hard.
Does paid leave under Article 7 include public holidays? Public holidays are separate from the 4-week annual leave guarantee. Most member states grant additional public holidays on top.
Summary
- Directive 2003/88/EC sets the EU minimum for working time

- Member states implement via national law and often go further
- The opt-out from the 48-hour cap is real but rare outside the UK and Ireland
- The 2019 CCOO ruling requires every member state to mandate working time recording
