Definition: What is a shift schedule?
A shift schedule is an instrument for personnel deployment planning. With a shift schedule, you can allocate employees spatially and temporally. A shift schedule allows you to cover qualitative and quantitative personnel needs and ensure that your company's target planning is achieved. It provides an overview of employees' working hours. If it is well organized, legal requirements can be met more easily.
Aspects of operational implementation
Is a shift schedule binding?
The duty roster is created through the employer's right to issue instructions in accordance with § 106 of the Trade, Commerce and Industry Regulation Act (GewO). Once it has been created and communicated to the employees, it has a binding effect on both sides. This means that both the employer and the employee are bound by the working hours specified in it. This announcement should be made in such a way that all employees are demonstrably informed of the schedule in good time.
How far in advance must employees receive the shift schedule?
The Working Time Act itself does not set an explicit deadline for the announcement of duty rosters. However, common minimum deadlines are derived from other laws and case law to ensure planning security for employees:
Four-day deadline according to § 12 TzBfG:
For work on call, the Part-Time and Fixed-Term Employment Act (TzBfG) provides for a notice period of at least four days. Although not directly applicable to every duty roster, this deadline is often used as a point of reference to ensure a certain amount of lead time.
Collective agreements and works agreements:
Many collective agreements or works agreements contain specific (often longer) deadlines for the announcement of duty rosters. These take precedence and must be strictly observed. An announcement made at too short notice can be legally challenged.
Can a shift schedule be changed easily?
Once announced, a duty roster is binding. Unilateral, short-term changes by the employer are generally inadmissible. If you want to change a duty roster, you have the following options:
Compliance with the notice period:
A change is permissible if you can again comply with the originally set or contractually agreed notice period.
Obtaining the employee's consent:
The simplest and safest method is the voluntary consent of the affected employee to the schedule change. This should be done in writing or in a verifiable digital form.
Presence of an operational emergency:
Only in really urgent and unforeseeable operational emergencies (e.g., machine failure, fire, acute staff failure due to illness at the last moment) can short-term, unilateral changes be justified. However, the principle of proportionality must always be observed and the interests of the employees must be taken into account as best as possible.
Shift Schedules and the Law: This is the Legal Basis
The Working Time Act forms the basis for all personnel planning. It protects the health of employees and defines clear limits for working and rest periods. Here are the crucial paragraphs you need to know for your shift scheduling:
§ 3 ArbZG: Daily and weekly maximum working hours
The core rule of the Working Time Act states that daily working hours must not exceed eight hours. Daily working hours can be extended to up to ten hours if an average of eight hours per day is not exceeded within six calendar months or 24 weeks. This is particularly relevant for shift operations that rely on flexible working hours to cover peak times. The compensation period must be strictly adhered to and documented.
§ 4 ArbZG: Rest breaks
For a working time of more than six to nine hours, a break of at least 30 minutes is prescribed. If your employees work longer than nine hours, the total break time is 45 minutes. These breaks can be divided into sections of at least 15 minutes each. It is important that the breaks constitute an interruption of working time and that employees can freely dispose of this time.
§ 5 ArbZG: Rest period
After the end of the daily working time, employees must have an uninterrupted rest period of at least eleven hours. For certain sectors such as hospitals, restaurants, transport companies, or agriculture, there are exceptions that allow the rest period to be shortened to up to nine hours. However, this shortening must be compensated for within one calendar month or four weeks by extending another rest period to at least twelve hours.
§ 6 and § 11 ArbZG: Regulations for night, Sunday and public holiday work
Employees who regularly do night work are entitled to appropriate compensation for the strain. This can be in the form of paid days off or a supplement to gross wages. In addition, regular occupational health check-ups are mandatory for night workers to prevent health problems.
In principle, Sunday and public holiday work is prohibited. Exceptions are clearly defined in the law for certain sectors and activities (e.g., rescue services, hospitals, gastronomy). A replacement day off must be granted for Sunday or public holiday work. For Sunday work, this must be granted within two weeks, for public holiday work within eight weeks.
Further Legal Frameworks and Parties Involved
The works council plays a central role in personnel deployment planning. According to § 87 of the Works Constitution Act (BetrVG), the works council has a comprehensive right of co-determination in social matters that directly affect duty roster planning:
- Start and end of daily working hours
- Distribution of working hours over the individual days of the week
- Introduction and design of shift work
- Temporary shortening or lengthening of customary working hours
- Principles of vacation planning
Disregarding the right of co-determination can lead to the invalidity of the duty roster and to claims for injunctions from the works council. Close and early coordination is therefore essential.
Data Protection Regulations (GDPR)
When creating and managing duty rosters, personal data of employees is processed. The principles of the General Data Protection Regulation (GDPR) must be strictly adhered to:
Data minimization:
Only the data that is absolutely necessary for duty roster planning may be collected and processed. This includes name, working hours, and place of assignment. Information that is not directly relevant for planning (e.g., detailed reasons for illness, private appointments) does not belong in the duty roster.
Transparency and purpose limitation:
Employees must be informed about the collection of their data and the purpose of the data processing.
Data security:
The data must be protected from unauthorized access, loss, or alteration. This is particularly important for digital duty roster systems.
Special Groups of People and Their Protection Regulations
Certain groups of employees enjoy special protection and have special working time regulations:
Youth Labor Protection Act (JArbSchG):
For minors, stricter rules apply regarding maximum working hours, breaks, rest periods, night, Saturday, Sunday, and public holiday work.
Maternity Protection Act (MuSchG):
Pregnant and breastfeeding mothers are not allowed to do night work, Sunday and public holiday work, or overtime. The design of the workplace must also be adapted to their needs.
Part-time and marginally employed workers:
Their working hours are often precisely defined in the employment contract and may only be changed with their consent. The general notice period for the duty roster also applies here.
Digitalization in Personnel Deployment Planning: With Software for a Legally Compliant Duty Roster
The manual creation of duty rosters can quickly become a major challenge in complex shift operations. Digital systems offer immense potential here.
Employee Participation and Modern Personnel Deployment Planning
Modern personnel deployment planning goes beyond mere compliance with legal requirements. It increasingly takes into account the needs of employees and promotes their active participation. Tools that allow employees to enter their availability themselves or swap shifts increase satisfaction and reduce conflicts. Especially in industries with shift rhythms, such as the 3-shift system, 4-shift system or 5-shift system in industry, it is important to involve employees in the planning process. This increases motivation and leads to a higher acceptance of the duty roster.

Siemens Energy: Increasing Efficiency through Digital Shift Scheduling
For a company like Siemens Energy, which employs over 91,000 people worldwide, shift scheduling is a complex matter. Typical challenges are unforeseen employee absences, changing order inquiries, and the coordination of different locations and qualifications.
To meet these requirements, Siemens Energy implemented a digital solution from shyftplan at selected locations. The automation of shift schedules led to a significant increase in efficiency.
In the case study, you can find out how Siemens Energy completely automated its complex shift models and sustainably improved its operational key figures.
Compliance with the Working Time Act (especially rest periods), any collective agreements, the co-determination rights of the works council, and timely announcement are the most important pillars.
Violations can be punished by the supervisory authorities (Trade Supervisory Office, Office for Occupational Safety) with fines of up to €30,000 per case.
If the duty roster is announced without complying with a deadline specified in a contract, collective agreement, or works agreement, employees can demand compliance with the deadline. They do not have to accept short-term changes that are associated with a late announcement. In case of doubt, labor courts can award remuneration for the original working hours.
In principle, employees cannot simply refuse a legally correct duty roster. The employer's right to issue instructions (§ 106 GewO) obliges staff to perform work according to the specifications of the schedule. However, there is a right to refuse if the schedule violates applicable laws (e.g., ArbZG), the employment contract, collective agreements, or works agreements.
