Shift Models (Working Hours) — Top 10 Systems Plus Examples
Shift models are applied wherever shift work is performed. In many companies, traditional 9-to-5 jobs are insufficient, as work needs to be conducted at different times. Various approaches exist side by side and ensure that the shift systems differ greatly in some cases. Ultimately, the focus is on the productivity of the company and the availability of staff at the right times. In human resource management, shift work demands particular attention and places specific requirements on IT systems for time recording.

Definition of Shift Work
While the term shift work is familiar to most people, their personal experiences with it are often limited. As a result, their perceptions of shift work may be somewhat vague. Defining the term can bring clarity and dispel uncertainties. Shift work refers to an employment model with staggered working hours. Employees work at different times and, consequently, in shifts.
The Advantages of Shift Work
Many companies rely on shift work because their production or services cannot be confined to regular working hours. Not only may shift work be necessary, but it can also be beneficial. Companies can profit from the following advantages:
- Expanding operating hours
- Maximizing machine utilization
- Flexible response to fluctuations in demand
- Enhancing customer service through 24/7 availability
Employees also benefit from shift premiums and bonuses, which increase their income. Moreover, employees often have free time during typical working hours, which can be advantageous in their daily lives. Since not all employees commute to work at the same time, traffic congestion around the workplace is also reduced, especially for larger companies.
The Disadvantages of Shift Work
While shift work can be appealing, it also has some downsides. Workers and companies should consider these negative aspects:
- Disruption of the circadian rhythm
- Difficulty balancing work with family life
- Health problems
- Lack of routine
- Constraints on leisure activities
Legal Regulations Concerning Shift Work
When it comes to shift work, it’s essential to weigh the pros and cons. Legal provisions also need to be taken into account since they set the framework for shift systems. In Germany, the Working Hours Act is particularly relevant, prescribing an average daily working time of eight hours. Furthermore, there needs to be a minimum of eleven hours of rest between two shifts. The Working Hours Act also mandates at least 15 non-working Sundays per year.
The provisions of the Working Hours Act directly affect shift work. Companies must adhere to the legal framework when organizing and scheduling shifts.
Distinguishing Shift Models
As HR managers or affected employees explore shift work, they’ll soon realize that various models are in use. The key factor in distinguishing different shift models is how many shifts are required for ongoing operations. It also depends on whether the shift system genuinely needs to ensure 24/7 operations. Different shift models are differentiated based on the cycle time and required number of shifts.
Checklist: Recognized Shift Models
When dealing with shift work, it’s not just the advantages and disadvantages that need to be considered. Various shift models are used in companies to maintain operations (sometimes around the clock) and offer flexible working hours to employees.
Here are some common shift work models:
- Fully continuous shift model
- Partial continuous shift model with night work
- Partial continuous shift model without night work
- Two-shift system
- Three-shift system
- Four-shift system
- Five-shift system
- Alternating shift model
5 Tips for Designing Shift Work
Shift work can be demanding for both companies and employees. Employees face numerous challenges, while organizations must make strategic decisions. Consider these five tips for designing shift work:
- Always adhere to the legal provisions of the Working Hours Act
- Take employees’ preferences into account
- Minimize night shifts if possible and avoid long stretches of night work
- Avoid scheduling more than five or seven consecutive working days for individual employees
- Opt for forward rotation from morning to afternoon and then to night shifts
Industries Relying Heavily on Shift Work
Shift work is indispensable in many fields. When work has to be carried out every day and around the clock, shift work is essential. The following industries serve as excellent examples:
- Fire departments
- Correctional facilities
- Power plants
In these industries, where order, safety, logistics, healthcare, or food services are involved, operating around the clock is standard. In manufacturing, shift operations are also often necessary to avoid the high costs and complexities associated with plant shutdowns.
Health Impacts of Shift Work
Employees engaged in shift work face significant health challenges. Legal regulations primarily serve to protect them, but they also need to take care of themselves. Especially those who work in a shift system on a long-term basis should be aware that this work method can jeopardize their health. The changing working hours and night shifts disrupt the natural circadian rhythm. This can lead not only to discomfort and stress but also to health issues. Below are a few examples of health problems experienced by shift workers:
- Sleep disturbances
- Cardiovascular diseases
- High blood pressure
- Digestion problems
What Are Shift Work Premiums?
Individuals who engage in shift work must adapt to unconventional working hours but, in return, receive shift work premiums. This increases their income, which is often a deciding factor for many people to work in a shift system.
Alternatives to Shift Work
For many companies, shift models are an effective means of optimizing production capacity, maintaining constant accessibility, and responding flexibly to work demands. In many sectors, such as healthcare, shift work is indispensable because facilities like hospitals need to be operational around the clock. In other areas, a reorganization of work processes can eliminate the need for night shifts. Therefore, HR managers should periodically review shift systems and continuously explore alternative options. Modern IT systems in workforce management can support this process.
Shift models are a common practice for many businesses and institutions because operations need to be maintained not only during typical core working hours but sometimes around the clock. Employees, therefore, have to engage in shift work and overcome the challenges that come with it. The use of modern IT solutions for time recording, workforce management, and staff planning allows for the effective accommodation of various shift models.
