Overtime under Dutch employment law
Dutch law does not contain a general statutory right to overtime pay. The Working Hours Act (Arbeidstijdenwet, ATW) regulates maximum working hours and rest periods but does not prescribe overtime compensation rates. Whether an employee is entitled to overtime pay, and at what rate, depends primarily on the employment contract and the applicable collective labour agreement (CAO).
Many collective agreements include overtime premiums, typically ranging from 25% to 100% above the regular hourly wage depending on the time of day, the day of the week, and whether the overtime falls on a public holiday. In the absence of a specific arrangement, the employee may still have a claim based on the principle of good employer practices (goed werkgeverschap) under Article 7:611 of the Dutch Civil Code. Dutch statutory law is entirely silent on overtime premium rates: the Working Hours Act sets maximum hours but does not mandate additional pay. Collective agreements often fix rates such as 150% of the hourly wage; in most higher-paid functions, overtime is considered included in the normal salary. Case law of the lower courts confirms that paying overtime rates only when the full-time hours ceiling is exceeded does not constitute unlawful discrimination of part-timers (Article 7:648 of the Dutch Civil Code), though the social partners may agree to award overtime pay from the first contractual overtime hour.
Maximum working hours and overtime limits
The ATW sets the maximum working time at 12 hours per shift and 60 hours per week, with an average of 48 hours over a 16-week reference period. Employers who require overtime must ensure these limits are not exceeded. Specific rules apply to night work and to employees under 18 years of age.
The employer must keep accurate records of hours worked, including overtime. The Nederlandse Arbeidsinspectie can inspect these records and impose fines for violations of the ATW. Following the CJEU ruling in CCOO v Deutsche Bank (C-55/18), employers in the Netherlands are required to maintain an objective and reliable system for recording daily working time. The general ATW ceiling is 12 hours per shift and 60 hours per week, averaged at no more than 48 hours over any 16-week reference period in line with EU Directive 2003/88/EC; overtime that pushes employees beyond these maxima is prohibited regardless of contractual agreement.
Can an employee refuse overtime in the Netherlands?
An employee can generally refuse overtime if the employment contract or CAO does not contain an overtime obligation. Even where such an obligation exists, the employer must take the employee's personal circumstances into account under the principle of good employer practices. Structural overtime that effectively amounts to a change of employment conditions requires the employee's consent or a valid justification under the Stoof/Mammoet framework.
