Working hours in transition: what the new IAB working time figures mean for businesses

Part-time work at a record level, a falling volume of work and a growing number of second jobs: the latest working time calculation by the Institute for Employment Research (Institut für Arbeitsmarkt- und Berufsforschung, IAB) shows just how much the world of work in Germany is changing. For employers that means: working hours are becoming more flexible, models more varied and the demands on clear processes are rising.

Die wichtigsten Fragen im Überblick

Why is the part-time rate in Germany rising so sharply?

Because more and more employees are choosing flexible working time models - for reasons such as family, health or a better work-life balance. According to the IAB, the part-time rate is above 40% for the first time

Why is the volume of work falling even though more people are working?

Because part-time work, sick days, vacation, less overtime and economic fluctuations mean that fewer hours are worked overall.

What role do second jobs play?

Second jobs continue to increase. Around 4.64 million employees have an additional job - which makes working hours more complex and calls for clean documentation

Part-time work is becoming the new normal 

In the second quarter of 2025 the part-time rate rose to 40.1% for the first time. That is an all-time high. Compared with the previous year, that means: 

  • + 1.3% more part-time staff 
  • - 0.7% fewer full-time employees 
  • Declining numbers of mini-jobs 
  • In total: 17 million people work part-time​​

So one thing is clear: part-time work is no longer a niche model but everyday reality - right across all industries. 

Employment is rising, but the hours worked are falling 

Although the number of people in work rose slightly to 46 million, the total volume of work fell by 0.5% to 14.5 billion hours. The reason: not everyone in work today works the same amount and many factors shorten or lengthen working hours. They include, for example: 

  • Order books: When the economy is doing badly, people often work less (through short-time work, for instance). 
  • Peak periods: In good phases there is more work and therefore overtime. 
  • Vacation, illness, public holidays: They reduce the target hours for the year. 
  • Part-time models: More and more people work fewer hours per week. 
  • Second jobs: The hours worked are spread across several jobs. 

Second jobs continue to increase 

In the second quarter of 2025, 4.65 million employees held a second job. That is an increase of 2.5% on the previous year. Per person, 7.4 hours were worked in second jobs, likewise an increase. For companies that means: 

  • People with more than one job have more complex working time profiles
  • The boundaries between jobs have to be clearly traceable 
  • Documentation becomes more important in order to avoid overwork or miscalculations 

Why these developments make digital tools indispensable

The figures show it very clearly: the world of work is becoming more granular, more flexible and more individual. With classic timesheets and Excel lists, this complexity can hardly be captured reliably any more. And this is exactly where clockin comes in. 

Companies today face challenges such as: 

  • different part-time models 
  • changing places of work 
  • seasonal fluctuations 
  • several jobs per person 
  • unpredictable overtime 

Digital time tracking makes sure that, despite all this variety, everything is documented cleanly, transparently and in a legally compliant way, without meaning extra work for employees or administration. 

clockin supports in particular: 

  • flexible working time models (full-time, part-time, shift-based or project-based) 
  • clean absence management 
  • automatic hours reports for payroll accounting 
  • documented overtime and working time accounts 
  • mobile use from anywhere 

A tool like clockin therefore helps you absorb exactly the trends that the IAB data is making increasingly visible.

Conclusion

The German working time landscape is changing fast: more part-time work, more second jobs, less overtime and a lower volume of work overall. For companies that means more variety, but also more administrative effort.

Anyone who records their working hours digitally, automatically and digitally today stays able to act - no matter how flexibly teams work.
