4-Shift Model: Advantages, Disadvantages + Template for 2026

What is the 4-Shift Model?

The 4-shift model (also called the 4-shift system) is a shift schedule where four separate teams alternate to maintain a 24/7 operation. Each team works rotating shifts – typically early, late, night, and off shifts.

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 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
