Continuous shift work (Kontischicht): models, examples and how to plan it

What is continuous shift work?

Kontischicht is the German short form for continuous shift work: your business runs without interruption, shift after shift. In manufacturing, in hospitals, in care, in the warehouse – wherever machines, patients or customers do not take a break.

There are two variants:

Full continuous operation – the business runs 7 days a week, 365 days a year, including Sundays and public holidays. Classic in chemicals, steel, paper, care and logistics.

Partial continuous operation – the business runs 24 hours without a break, but only on working days. At the weekend the machines stand still. Common in manufacturing where Sunday work is not possible for legal or collective agreement reasons.

The common continuous shift models

There is no single model. Which one fits depends on how many employees you have, how high your capacity utilisation is and what is permitted from an occupational science and a collective agreement point of view.

3-shift system

Three shifts a day: early (06:00–14:00), late (14:00–22:00), night (22:00–06:00). Three groups take turns, each works the same shift for a week and then rotates on. For full continuous operation this does not add up – because nobody is allowed to work 7 days a week straight through. For partial continuous operation it is the standard model.

4-shift system

Four groups cover the 24/7 workload. The rhythm typically runs like this: a few days early, a few days late, a few days night, then off. The average weekly working time here is around 42 hours.

5-shift system

Five groups instead of four – that noticeably eases the load. The average weekly working time is around 33–34 hours, and each employee gets around 146 days off a year. That is more expensive in terms of staffing, but healthier and more attractive to skilled workers.

Example: 2 early, 2 late, 2 night, 2 off

The 2-2-2 model (often called the “continental model”) is a well-known variant within the 4-shift system:

• 2 days early shift
• 2 days late shift
• 2 days night shift
• 2 days off

Then the rhythm starts again. The main advantage is the short shift blocks – nobody has to work five nights in a row. That matches occupational science recommendations. However: the pattern changes quickly, and some employees find that hectic.

Days off on continuous shift work – how many are there?

Per continuous shift model, the balance looks roughly like this:

• 3-shift system (partial continuous): around 104–120 days off
• 4-shift system (full continuous): around 91 days off
• 5-shift system (full continuous): around 146 days off

On top of that comes the vacation entitlement. Remember: the more groups, the more time off – because the load is spread across more shoulders.

Continuous shift premium: what are you entitled to?

This is where statute and collective agreement part ways.

Set out in law: Under Section 6(5) of the German Working Hours Act (Arbeitszeitgesetz, ArbZG), the employer must grant an appropriate premium for night work – or alternatively paid days off. The case law of the Federal Labour Court treats 25% as the benchmark, and more for permanent night work.

Set out in the collective agreement or contract: Sunday and public holiday premiums are not required by law – they are set out in the collective agreement or the employment contract. Usual rates are:

• Sunday: 50% premium
• Public holiday: 100–150% premium
• Night: 25% premium

Calculating pay on continuous shift work

This is how you work out continuous shift pay realistically:

1. Base pay: hourly wage × hours worked.
2. Night premium: night hours × base hourly wage × 25%.
3. Sunday premium: Sunday hours × base hourly wage × 50% (or the collectively agreed rate).
4. Holiday premium: public holiday hours × base hourly wage × 100–150% (or the collectively agreed rate).

Continuous shift work and health

Continuous shift work is not a neutral working rhythm. The Federal Institute for Occupational Safety and Health (Bundesanstalt für Arbeitsschutz und Arbeitsmedizin, BAuA) lists the typical risks:

• Sleep disorders from a disrupted day-night rhythm
• Increased risk of cardiovascular and metabolic disease
• Digestive problems from irregular meals
• Social strain from working at weekends and on public holidays

What helps, from an occupational science point of view:

• Short night blocks – a maximum of 3 night shifts in a row.
• Forward rotation – early → late → night, never backwards.
• Enough rest time – the ArbZG requires at least 11 hours between two shifts (Section 5).
• Predictability – fixed rotations instead of spontaneous shift swaps.

Planning continuous shift work without chaos – how it works with clockin

Continuous shift work has one particular quality: think it through once and it rolls on permanently. The model has to be right, then it runs – with small adjustments for vacation, sickness and peaks in workload.

With shift scheduling and shift planning from clockin you do exactly that:

• Define shifts once – as an individual or a recurring shift, staffed by drag and drop.
• Automatic alerts for double booking, absence or exceeded hours – mistakes show up before the plan goes out.
• Time tracking built straight in – shift planning builds on clockin time tracking. A planned vs. actual comparison shows you immediately when recorded working hours deviate from the plan.
• Payroll without a break in the chain – data is passed straight on via the DATEV integration or a Lexware Office export.
• Absences and swaps in one view – vacation, sickness and shift swaps all run centrally through the app; your team is notified of changes in real time.

That replaces what is still standard in many continuous shift businesses: the shift schedule in Excel, corrections by phone, timesheets on paper. clockin saves you the chasing around and gives your employees transparent schedules straight on their phone.

Conclusion

Continuous shift work is not rocket science – but it needs a clear model, clean calculations for premium pay and a plan that is not cobbled together anew every week. Choose the model according to your headcount and the limits of what your people can take: 5-shift systems are more modern and healthier, 4-shift remains the industry standard.
