4-day week in IT: opportunities, risks and implementation in 2025

Why the 4-day week is up for debate

In the IT sector, the 4-day week model is increasingly taking centre stage in current discussions. While at first glance the prospect of a better work-life balance is convincing, complex questions arise in day-to-day operations: Can innovation and productivity be maintained in shorter working time models? How do organisations and their employees make targeted use of the advantages of a compact working week?

Companies in the IT sector in particular, which are faced with rapid technological developments, a shortage of skilled labour and extensive digital collaboration, are looking for sustainable and flexible working models. While start-ups are experimenting with new approaches, large companies are venturing their first pilot phases. At the same time, there is increasing pressure from the workforce to reconcile work and life goals. It is foreseeable that many companies will make a fundamental decision about working time models in 2025.

The changing world of work: status quo and new expectations

For a long time, the classic 40-hour working week model was considered the industry standard. Expectations have shifted, at the latest due to developments during the coronavirus pandemic: Home office, agile forms of work and flexible presence options are firmly established components of the IT working world. This is associated with an increased demand for regeneration times and phases of concentrated work without jeopardising innovation and stability. In this context, the 4-day week is seen as a realistic and serious option.

For many in IT practice, it has become clear that activities such as software development, cloud operations or user support can be carried out efficiently regardless of fixed office hours. Projects are increasingly being managed on the basis of measurable results rather than pure presence at the workplace. The first companies to adapt their working time models have reported noticeably higher team satisfaction, increased motivation and reduced staff turnover.

Productivity versus time: is less really more?

The claim that working fewer hours increases performance is a key aspect of the 4-day week. The results of empirical studies - for example from Iceland and the UK - show a significant reduction in fatigue-related performance losses, particularly in knowledge-based professions. At the same time, focus and goal-orientation benefit noticeably.

For a medium-sized IT system house in Munich, a pilot test of the 4-day week in 2024 initially meant restructuring tasks and focussing on targeted meetings and more efficient communication processes. After six months, the managers realised that overall output had not fallen; on the contrary, software deliveries had increased by 15 per cent, while sick days had fallen.

However, such effects require a well thought-out approach. Where attempts are made to spread the weekly number of hours over four days without any changes, this often leads to overtime and exhaustion. Processes and targets should be critically scrutinised and personal responsibility systematically encouraged. An example of a successful formulation in a job offer: "We offer a 4-day week with 32 hours and expect results-orientation instead of presence."

Opportunities for job seekers - new arguments on the labour market

The 4-day week is becoming increasingly important as a criterion in recruitment. Employers who openly communicate this working model in job advertisements position themselves as modern, employee-orientated and attractive to qualified specialists. Especially for applicants who have several options, such as experienced software developers or DevOps engineers, the shorter week can be a decisive advantage.

A specific experience report: A DevOps Engineer decided to work for a company that had introduced a regular four-day week. "The opportunity to use three days in a row for my own projects or further training was ultimately the deciding factor. The additional flexibility gives me noticeable relief after challenging release phases." The use of the extra day ranges from organising private time to voluntary work and targeted personal development.

A targeted application tip: If you are applying for jobs with a 4-day week, you should emphasise your ability to organise yourself and achieve goals in your cover letter. For example: "My experience in agile project management enables me to work efficiently in a team and to meet deadlines independently. I look forward to using the 4-day week model to further strengthen my ability to achieve my goals."

Risks and challenges: What companies need to consider

The switch to a 4-day week brings with it numerous challenges. For example, the question arises as to how service and support times can be reliably guaranteed or how to deal with project peaks that require temporary additional work. In addition, internationally operating IT teams are faced with the task of coordinating various legal provisions and public holiday regulations.

Before implementation, a structured review process is recommended in which the HR department and specialist departments jointly analyse which tasks benefit from time flexibility and in which areas physical presence remains essential. A gradual introduction - for example with pilot teams, regular feedback rounds and structured retrospectives - has proven to be promising. Managers are faced with the task of formulating clear targets and strengthening confidence in personal responsibility.

A common misjudgement is the assumption that all challenges can be solved with the introduction of the 4-day week. Flexibility is still required, especially for short-term tasks such as bug fixes. Transparent communication and comprehensible rules for dealing with overtime and its compensation are important.

Practical implementation: How the 4-day week works in IT

A successful introduction of the 4-day week requires more than just a reduction in weekly working hours. In the IT sector, it is advisable to first analyse existing processes: Where can face-to-face meetings be replaced by digital collaboration, which routines can be automated? Many companies have benefited from shorter stand-ups and efficient coordination via Slack or Jira, for example.

The introduction of flexible rest days can also be useful. For example, a team might choose Friday as a joint day off, while support or operational units take alternating breaks on Thursdays or Mondays. Clear handover communication, for example through status messages and documented handovers in the ticket system, contributes to smooth collaboration. Automation solutions help to streamline standard processes and prevent bottlenecks.

Continuous reflection remains important: regular team meetings - for example every two weeks - allow models to be adapted and ensure an open error culture. The 4-day week should also be understood as a dynamic concept that can be flexibly adapted to team size and project phases.

Many IT specialists use the additional day off specifically for further training, involvement in open source projects or working on their own ideas. Companies promote this development by providing access to learning platforms or offering individual budgets for personal development, for example. A tried and tested approach: "Employees can use part of their day off every two months to acquire certified knowledge."

Outlook for 2025: what could happen next

Looking ahead to 2025, the further development of the 4-day week remains a key issue for the IT working world. In the face of increasing competition for qualified specialists and growing demands for flexibility, companies feel compelled to further develop their models. Experiences from pilot projects of both large technology groups and smaller providers are continuously providing new insights and promoting an open exchange.

Both employers and applicants have the opportunity to benefit from the potential of the 4-day week. A willingness to experiment and a pragmatic approach to new concepts will be crucial. The world of work in the IT sector is evolving - and the 4-day week is becoming a permanent fixture in the range of attractive working models.

Conclusion: Finding a balance, utilising potential

The 4-day week opens up new perspectives for the IT sector. Companies that adapt structures, obtain continuous feedback and promote flexible solutions will benefit just as much as their employees. The coming year will show how lasting the changes will be in everyday working life.
