Overtime refers to working hours that exceed the contractually agreed regular working time. It must be compensated either through payment or time off in lieu, provided it was ordered, approved, or tolerated by the employer. The German Working Hours Act (Arbeitszeitgesetz) limits daily working time to a maximum of 10 hours – with compensation required to average 8 hours over a 6-month period.
Definition: What Is Overtime?
Overtime refers to working hours that exceed the regular working time specified in the employment contract or collective agreement. For example, if you have a 40-hour contract and work 45 hours in a week, you have worked 5 hours of overtime.
It's important to distinguish overtime from "Mehrarbeit" (additional work): While overtime refers to hours exceeding the contractually agreed working time, Mehrarbeit under the German Working Hours Act (Arbeitszeitgesetz) means exceeding the statutory maximum of 8 hours per working day. If you work 9 hours on a given day, you're working 1 hour of Mehrarbeit under the ArbZG – regardless of what your contract states.
In practice, both terms are often used interchangeably. However, for HR professionals, the distinction is relevant as stricter statutory compensation requirements apply to Mehrarbeit.
Legal Framework
Working Hours Act (ArbZG) – Maximum Working Time
The German Working Hours Act defines in Section 3 that daily working time generally may not exceed 8 hours. An extension to up to 10 hours is permitted if an average of 8 hours per working day is not exceeded within 6 calendar months or 24 weeks.
Since Saturday counts as a working day, this results in a maximum weekly working time of 48 hours. Temporarily, up to 60 hours are possible – but only with corresponding compensation. Violations can result in fines of up to €30,000 for the employer.
Compensation Entitlement Under Section 612 BGB
The German Civil Code (Bürgerliches Gesetzbuch) stipulates in Section 612 that compensation is deemed tacitly agreed if the service can only be expected against payment under the given circumstances. This means: overtime must generally be compensated – either through payment or time off in lieu.
However, the prerequisite is that the overtime was ordered, approved, or at least tolerated by the employer. If an employee works longer on their own initiative without the employer's knowledge or acceptance, there is no automatic entitlement to compensation.
Works Council Co-determination (Section 87 BetrVG)
If a works council exists in the company, it has a mandatory co-determination right regarding the ordering of overtime. According to Section 87(1) No. 3 of the Works Constitution Act (BetrVG), the works council must consent before overtime is ordered – even if it only affects individual employees.
Without this consent, the overtime order is generally invalid. HR professionals should therefore communicate with the works council early and establish clear processes for overtime approval.
Overtime in Practice
Ordering Overtime
In principle, there is no obligation to work overtime – unless this is expressly agreed in the employment contract, collective agreement, or works agreement. No unilateral authority to order overtime can be derived from the employer's general right to direct.
An exception is genuine emergencies: unforeseeable events such as natural disasters, technical failures, or comparable situations that threaten operations. Mere capacity bottlenecks or increased workload do not qualify as emergencies and do not justify an obligation to work overtime.
When ordering overtime, the employer must also exercise reasonable discretion and consider the interests of employees – such as childcare responsibilities or dependence on public transportation.
Payment or Time Off in Lieu
Compensation for overtime depends on what is agreed in the employment contract or collective agreement. There are basically two options:
Payment: Overtime is compensated at the regular hourly rate. Supplements (e.g., 25% for overtime, higher for night or weekend work) are only payable if contractually or collectively agreed.
Time off in lieu: Overtime is compensated through corresponding time off. When this compensation takes place is generally decided by the employer – employees have no right to determine the timing themselves.
If an employee falls ill during overtime compensation, the sick days are not credited. Time off in lieu is not vacation time – the risk is borne by the employee.
Calculating Overtime – With Formula
To calculate the value of an overtime hour, use the following formula:
Hourly rate = Gross salary ÷ (Weekly hours × 4.33)
Example: An employee earns €3,000 gross with a 40-hour week.
- €3,000 ÷ (40 × 4.33) = €3,000 ÷ 173.2 = €17.32 per hour
- For 10 overtime hours, this results in: 10 × €17.32 = €173.20 gross
With supplements, the amount increases accordingly. A 25% overtime supplement would mean an additional €4.33 per hour in the example.
Overtime Clauses in Employment Contracts
Many employment contracts contain clauses for flat-rate compensation of overtime. The following applies: not every formulation is valid.
Invalid are blanket clauses such as "Overtime is covered by the salary." These are too vague and unfairly disadvantage employees, as it is unclear how many hours are meant.
Valid are clauses that specify a concrete number, e.g., "Up to 10 overtime hours per month are covered by the salary." The Hamm Regional Labor Court ruled that for a 40-hour week, up to 10 overtime hours per month can be covered by the salary (judgment of 22.05.2012 – 19 Sa 1720/11).
As a rule of thumb: a maximum of 10% of the agreed weekly working time can be covered by flat-rate compensation. For senior executives with hiring and firing authority, more extensive flat-rate compensation is customary and legally permissible.
Overtime: Facts and Figures 2024
According to the IAB Working Time Calculation, overtime in Germany is at a historic low. In the third quarter of 2024, fewer overtime hours were worked than ever before. Employees worked an average of 13.1 paid and 15.1 unpaid overtime hours per year – a decrease compared to the previous year.
The Federal Statistical Office reports that in 2024, almost 4.4 million employees worked overtime – equivalent to about 11% of all employees. Men worked overtime more frequently at 13% than women (10%). Overtime is particularly common in the finance and insurance sector (17%) and energy supply (16%).
Nevertheless, the total volume remains significant: the overtime worked corresponds to more than 750,000 full-time positions. 71% of those affected use a working time account for compensation, while 19% work unpaid overtime.
Frequently Asked Questions About Overtime
How much overtime is allowed?
There is no specific statutory limit for overtime itself. However, the Working Hours Act limits daily working time to a maximum of 10 hours. With a 6-day week, this results in a maximum weekly working time of 60 hours – but only temporarily and with compensation to an average of 48 hours within 6 months. With a 40-hour contract, a maximum of 8 overtime hours per week is permanently possible.
Do I have to work overtime?
In principle, no – an obligation only exists if expressly agreed in the employment contract, collective agreement, or works agreement. In genuine emergencies (unforeseeable events), an obligation may arise from the duty of loyalty. Mere capacity bottlenecks or order peaks do not qualify as emergencies.
Must overtime be paid?
Yes, if it was ordered, approved, or tolerated. Compensation can be through payment or time off in lieu – depending on the contractual agreement. Without an explicit arrangement, the regular hourly rate applies according to Section 612 BGB.
Are "overtime included in salary" clauses allowed?
Blanket clauses without a specific number of hours are invalid. Formulations with a concrete number are permissible, e.g., "10 overtime hours per month are included in the salary." The guideline is: maximum 10% of the agreed working time.
When does overtime expire?
The statutory limitation period is 3 years (Section 195 BGB). However, employment contracts may contain shorter exclusion periods – these must be at least 3 months. Collective agreement forfeiture periods must also be observed. Careful documentation is important to prove entitlements.
What is the difference between overtime and Mehrarbeit?
Overtime exceeds the contractually agreed working time; Mehrarbeit exceeds the statutory maximum working time of 8 hours per day. Example: With a 40-hour contract and a 45-hour week, you have 5 hours of overtime. If you work 9 hours on one day, you have 1 hour of Mehrarbeit under the ArbZG.
Does the works council have a say in overtime?
Yes, the works council has a mandatory co-determination right under Section 87(1) No. 3 BetrVG. This also applies to overtime for individual employees. Without the works council's consent, the overtime order is invalid.
How is overtime handled upon termination?
Even upon termination, the right to compensation or time off in lieu remains. In practice, overtime is often reduced through time off before the end of the notice period. Alternatively, payment is made with the final salary statement.
Conclusion
For HR professionals, overtime is a multifaceted topic: legal requirements of the Working Hours Act, compensation issues, and works council co-determination rights must all be considered. Clear documentation of working hours protects both sides – employers from compliance risks and employees when asserting their claims.
Particularly important: flat-rate compensation clauses are only valid if they specify a concrete number of hours. The trend also shows that overtime is declining – a development that benefits work-life balance and employee satisfaction.
