Certain groups of employees – including pregnant workers, people with severe disabilities, and employees with documented health impairments – are legally entitled to exemption from shift work or night work under defined conditions. The key legal provisions are § 6 para. 4 of the Working Hours Act (Arbeitszeitgesetz, ArbZG), the Maternity Protection Act (Mutterschutzgesetz, MuSchG), and Book IX of the Social Code (SGB IX). As an HR professional, you should be familiar with the eligibility requirements in order to act correctly and in compliance with the law.
What Does Exemption from Shift Work Mean?
Exemption from shift work refers to an employee's right to be relieved of shift or night work duties for specific reasons – and to be reassigned to a daytime position instead. This constitutes a right of reassignment: the employee does not lose their job but transitions to different working hours.
An important distinction: according to § 2 para. 4 ArbZG, night work covers activities that take place for more than two hours between 11 p.m. and 6 a.m. Shift work describes rotating working hours (e.g. early, late, and night shifts). Employees seeking exemption from shift work most commonly refer to the night work component – as this is the most strictly regulated under German law.
The statutory exemption entitlement must be distinguished from contractual or collectively agreed rights: some collective bargaining agreements (Tarifverträge) or works agreements (Betriebsvereinbarungen) grant more extensive rights – for example, to parents or employees caring for relatives. The rule of thumb: always review both levels.
Legal Framework
§ 6 Para. 4 ArbZG – Exemption on Health Grounds
The core provision for health-related exemption entitlement is found in § 6 para. 4 ArbZG. Under this provision, an employer must reassign night workers to a suitable daytime position upon their request, provided the following conditions are met:
- Night work demonstrably endangers the health of the person concerned.
- A medical certificate confirms the connection between night work and the health impairment.
- A suitable daytime position exists within the company and reassignment is reasonable.
If no suitable daytime position is available, or if reassignment is unreasonable for operational reasons, the employer's obligation lapses under § 6 para. 4 sentence 2 ArbZG. However, the employer must provide concrete evidence of this and is required to make a genuine effort to find a solution.
Maternity Protection: MuSchG and Night Work
Pregnant and breastfeeding employees enjoy special protection. Under the Maternity Protection Act (MuSchG), there is generally a prohibition on night work between 8 p.m. and 6 a.m. (§ 5 MuSchG). Exceptions are only permissible under strict conditions (including voluntary consent, a medical certificate, and absence of any risk).
For HR departments, this means: as soon as an employee notifies the company of her pregnancy, it must be assessed promptly whether and in what form continued employment in the existing shift model is permissible. In case of doubt, the prohibition applies.
Severe Disability: SGB IX § 164
Employees with severe disabilities have the right to refuse overtime under § 164 para. 4 SGB IX. Although night work is not explicitly mentioned, this provision – read in conjunction with the general right to disability-appropriate employment – implies that severely disabled employees are entitled to have their working conditions adapted. This can include exclusion from night shifts where these are incompatible with the disability.
Works Council and Co-Determination Rights (§ 87 BetrVG)
When drawing up or amending shift schedules, the works council (Betriebsrat) has mandatory co-determination rights under § 87 para. 1 no. 2 of the Works Constitution Act (BetrVG). This means: changes to shift models or the reassignment of employees to daytime work should – where a works council exists – be coordinated with it at an early stage.
Who Is Entitled? Overview by Employee Group
Applying for Exemption – Process for HR Departments
Step-by-Step: Application Process
- Employee submits request: The affected person submits a written request for exemption from shift or night work, along with the relevant supporting documentation.
- Review documentation: HR reviews the submitted evidence for completeness and plausibility.
- Search for a suitable daytime position: The employer is obligated to make a genuine and documented effort to identify a suitable alternative position.
- Make and communicate a decision: If a suitable position exists, reassignment is carried out. If this is not possible, the refusal must be provided in writing with clear reasoning.
- Involve the works council: Where one exists, the works council must be involved in changes to shift schedules (§ 87 BetrVG).
Required Documentation
- Written request from the employee
- Medical certificate stating the connection between shift/night work and the health impairment (for § 6 para. 4 ArbZG)
- Severe disability ID card (for SGB IX)
- Medical certificate pursuant to § 14 MuSchG (for pregnancy/breastfeeding)
What If No Daytime Position Is Available?
The employer is first required to conduct a genuine, documented search – this may include reorganisation, internal transfer, or temporary solutions. Only once it has been demonstrated that no suitable daytime position exists and reassignment is genuinely unreasonable does the obligation under § 6 para. 4 sentence 2 ArbZG lapse. In the event of a dispute, the labour court decides. Refusal of an exemption request does not, by itself, constitute grounds for special termination rights for the employee.
Frequently Asked Questions on Shift Work Exemption
Who has a statutory right to exemption from shift work?
Employees with documented health impairments caused by night work (§ 6 para. 4 ArbZG), pregnant and breastfeeding women (MuSchG), and severely disabled employees (SGB IX § 164 para. 4) all have statutory entitlements. In addition, collective bargaining agreements or works agreements may provide more extensive rights, for example for parents or employees caring for relatives.
What exactly does § 6 para. 4 ArbZG regulate?
§ 6 para. 4 ArbZG gives employees the right to be reassigned to a daytime position if a medical certificate confirms that night work endangers their health. The employer must identify a suitable daytime position and carry out the reassignment – unless no such position is available or reassignment is demonstrably unreasonable.
What documents does the HR department need?
Depending on the grounds for exemption, the following documents are required: a medical certificate confirming the link between night work and the health impairment; a severe disability ID card (if applicable); a medical certificate pursuant to § 14 MuSchG (in the case of pregnancy or breastfeeding). A written request from the employee is also recommended.
Can the employer refuse the exemption?
Yes, but only under narrow conditions: if it can be demonstrated that no suitable daytime position exists and reassignment is unreasonable. The employer must document the search. In the event of a dispute, the burden of proof lies with the employer. The works council has co-determination rights regarding the design of shift schedules under § 87 BetrVG.
Do parents or single parents have a statutory right to exemption?
The ArbZG does not provide a general statutory right to exemption on childcare grounds. However, entitlements may arise from applicable collective bargaining agreements or works agreements. A case-by-case assessment is recommended – and the works council should be involved where appropriate.
Is the exemption permanent or only temporary?
This depends on the reason for the exemption. In the case of pregnancy and breastfeeding, the exemption is time-limited. For permanent severe disability or chronic illness, the entitlement may be ongoing. Regular reassessment of the situation – particularly for health-related grounds – is advisable.
Can an employee refuse night shifts on health grounds without providing a medical certificate?
No. A medical certificate is a prerequisite for an entitlement under § 6 para. 4 ArbZG. A mere assertion of a health impairment is not sufficient. The certificate must document the causal link between night work and the impairment.
What happens if no suitable daytime position is available?
The employer is first required to make a genuine effort to find a solution. If this is demonstrably not possible, the reassignment obligation under § 6 para. 4 sentence 2 ArbZG lapses. However, this does not automatically result in termination of the employment relationship. The works council must be involved in such processes.
Conclusion
Exemption from shift work is not a blanket right – it is tied to specific conditions. As an HR professional, it is advisable to be well acquainted with the three key legal provisions – § 6 para. 4 ArbZG, MuSchG, and SGB IX – and to document application procedures thoroughly. A structured approach protects both the employees concerned and the company from legal risk.
