4-Shift Model & 4-Shift System: Template, Cycle, Pros and Cons

What is the 4-Shift Model?

Short answer: The 4-shift model, also known as a 4-shift system, is a schedule where four teams rotate to keep an operation running around the clock. The typical rotation covers early shift, late shift, night shift and off shift. For employers it creates stronger coverage and predictability; at the same time, staffing needs, allowances and coordination effort increase.

In practice, a 4-shift system mainly fits companies with 24/7 operations or very long opening hours. Important: the template below is a planning example, not a legal shortcut. Working hours, rest periods, night/Sunday work and collective agreement rules must be checked for the specific business.

This model is commonly used in industries that require continuous production or service:

• Industry and Production: Chemicals, pharmaceuticals, automotive
• Healthcare: Hospitals, nursing homes
• Logistics & Transport: Distribution centers, airports
• Energy & Utilities: Power plants, waterworks
• Security Services: Property protection, surveillance

The big difference compared to the 3-shift model: The 4-shift system provides more recovery time between shifts – at the cost of requiring more personnel.

How Does the 4-Shift Model Work? The Typical Rhythm

The classic 4-shift model is based on a 4-day cycle. Each of the four teams goes through the following shifts:

Standard 4-Shift Cycle

Then the cycle starts over. Each team works 3 days and then has 1 day off.

Alternative: 4-Shift Model with Longer Off Shifts

Some companies use an extended cycle with more consecutive off days:

• 2-2-3 Model: 2 days early shift, 2 days late shift, 3 days off (then rotation)
• 4-4-4 Model: 4 days work (rotating shifts), 4 days off

These variants increase predictability for employees but require more staff and more complex planning.

Advantages of the 4-Shift Model

For Employers

• Continuous operating hours: 24/7 production without interruption
• Higher utilization: Machines and equipment run around the clock – maximum efficiency
• Less overtime: With four teams, workload is better distributed, fewer absences due to illness or overload
• Planning reliability: Clear rotation, fewer conflicts in shift scheduling
• Competitive advantage: Faster delivery times, higher production capacity

For Employees

• Regular rhythm: Predictable shift rotation – you always know when you work
• More consecutive free time: Compared to the 3-shift model, there are more frequent longer free phases
• Allowances: Night, Sunday and holiday allowances (at least 25% for night work in Switzerland, see Night Allowance Switzerland)
• Flexibility: Free days can be used for appointments, family or hobbies
• Lower burnout risk: Better work-life balance than with 3-shift or permanent night shifts

Disadvantages of the 4-Shift Model

For Employers

• Higher personnel costs: Four teams mean more employees – plus allowances for night and weekend work
• More complex planning: Vacation coverage, sick leave and training must be coordinated across four teams
• Communication effort: Four teams never work simultaneously – information transfer is more difficult
• Training time: New employees need longer to adapt to the rhythm

For Employees

• Strain on biorhythm: Constant switching between early, late and night shifts can disrupt sleep
• Social restrictions: Weekend and holiday work, irregular working hours complicate family life and friendships
• Health risks: Long-term shift work increases risk of sleep disorders, cardiovascular diseases and gastrointestinal problems
• Less spontaneous free time: Free days are fixed, spontaneous activities are harder to plan
• Adjustment phase: Some people never fully adapt to shift work

Conclusion: The 4-shift model offers the best balance between operating time and recovery time – but only if you cope well with shift work.

Template: Sample Schedule for the 4-Shift Model

Here is a practical 4-week shift schedule for four teams (A, B, C, D). Each team works on a 4-day cycle.

Week 1

Week 2

The cycle repeats over weeks 3 and 4.

When is the 4-Shift Model Worthwhile?

The 4-shift model is not suitable for every company. Here are the main criteria:

The 4-Shift Model fits if…

• …your company must operate 24/7 (e.g. production, hospital, logistics)
• …you have enough staff to form four teams (at least 20-30 employees)
• …your employees are willing to work shifts (including night and weekend shifts)
• …you want to achieve a high utilization of your equipment
• …personnel costs are offset by higher productivity

The 4-Shift Model does NOT fit if…

• …you only work during the day or until evening → Then a 2-shift model is sufficient
• …you have too few staff → One team absence endangers the entire operation
• …your order situation fluctuates strongly → Then flexible models are better (e.g. part-time, floaters)
• …your employees are not healthy enough for shift work

FAQ: Frequently Asked Questions about the 4-Shift Model

How many employees do I need for a 4-shift model?

At least 4 employees per position – so one team per shift. In practice, you should also plan for floaters or reserve employees (about 10-20% more) to cover vacations, illness and training.

How high are the allowances in the 4-shift model?

In Switzerland, the following minimum allowances apply:

• Night work (23:00-06:00): at least 25%
• Sunday work: depending on collective agreement 50-100%
• Holiday work: depending on collective agreement 100-200%

Many collective labour agreements (GAV) provide for higher allowances. More details: Night Allowance Switzerland

Can I as an employee refuse the 4-shift model?

It depends on your employment contract. If it states that shift work is part of your duties, you must generally agree. If such a clause is missing, you can refuse shift work.

Is the 4-shift model healthier than the 3-shift model?

Yes, generally it is. The 4-shift model offers more recovery time between shifts and longer free phases. But: Shift work in general strains health. Important are:

• Regular medical check-ups (mandatory from 25 nights/year in Switzerland)
• Healthy diet, exercise, sufficient sleep
• Bright workspaces, ergonomic workplaces

How do I plan vacation in the 4-shift model?

Vacation planning must be coordinated early – ideally 3-6 months in advance. Only one person per team should take vacation at the same time to keep shifts staffed. Good shift planning software helps a lot (e.g. job.rocks).

What is the difference between the 4-shift model and continuous shift work?

"Continuous shift work" is the umbrella term for all models that run 24/7. The 4-shift model is a specific variant of this – with four rotating teams.

Are there legal requirements for the 4-shift model in Switzerland?

Yes. The Labour Act (ArG) regulates:

• Maximum working hours: max. 45-50 hours/week (depending on industry)
• Rest periods: at least 11 hours between shifts (can be reduced to 8 hours if compensated within 24 hours)
• Night work: max. 10 hours per shift, at least 25% allowance
• Sunday work: only with permission, allowance according to collective agreement

Conclusion: Is the 4-Shift Model Right for You?

The 4-shift model is a proven system for companies that must operate around the clock. It offers a good balance between operating time and recovery time – but only if you have enough staff and your employees cope well with shift work.

Advantages summarized:

• 24/7 operation possible
• Regular, predictable rhythm
• Better work-life balance than 3-shift
• Higher productivity and equipment utilization

Disadvantages summarized:

• Higher personnel costs
• Strain from shift work (health, social life)
• More complex planning
