Night work under the Working Hours Act
Night work (nachtarbeid) in the Netherlands is regulated by the Working Hours Act (Arbeidstijdenwet, ATW) and the Working Hours Decree (Arbeidstijdenbesluit). A night shift is defined as a shift that includes at least one hour of work between midnight and 06:00. An employee is considered a night worker if they work night shifts at least 16 times per 16-week reference period.
The maximum working time for night workers is more restrictive than for day workers. An employee may not work more than ten hours in a night shift. Over a 16-week reference period, the average working time of night workers may not exceed 40 hours per week, compared to 48 hours for day workers. These limits reflect the additional health burden associated with working at night and implement the requirements of EU Directive 2003/88/EC. Night work is classified among psychosocial work burdens under Article 3(2) of the Health and Safety at Work Act, placing a positive obligation on the employer to prevent or limit its harmful effects as part of the company health and safety policy. Night workers must also receive at least 46 hours of uninterrupted rest after a consecutive series of night shifts, a more stringent requirement than for day workers.
Rest periods and recovery time under Dutch law
After a night shift, the employee is entitled to an uninterrupted rest period of at least 14 hours, or in exceptional cases no less than eight hours. The ATW also restricts the frequency of night shifts: in principle, an employee may work no more than five consecutive nights, and must have at least 46 hours of uninterrupted rest after a series of night shifts. These rules cannot be deviated from by contract alone - only a collective labour agreement (CAO) may provide for derogations within the limits of the ATW.
Special protection for certain groups under Dutch law
Night work is prohibited for employees under 18 years of age. Pregnant employees and those who have recently given birth have a right under Article 4:5 of the Work and Care Act (Wet arbeid en zorg, WAZO) to be transferred to daytime work if a doctor certifies that night work poses health risks. If a transfer is not possible, the employer must grant exemption from night work, with continued pay. The Dutch Labour Inspectorate (Nederlandse Arbeidsinspectie) monitors compliance and can impose fines for violations of the ATW night work provisions. The Netherlands has abolished all former sex-specific prohibitions on night work (such as restrictions on women in certain trades) in order to ensure equal career opportunities; current restrictions are based exclusively on health grounds such as pregnancy or medical certification, rather than gender (see Article 4:5 WAZO and Article 7:646(3) of the Dutch Civil Code).
