Mandatory Office Attendance: Meaning and Rules for Working in the Office

You hear it more and more in the media: many companies want "more presence" or "Back to Office" to be pushed. Companies that introduced home office or remote work during the Covid pandemic are gradually trying to make the office more attractive again.

Employers are once again setting specific days for teams to work on-site together. This is exactly where the topic of mandatory office attendance comes into play: it describes binding requirements for being present at the workplace, such as on specific days of the week or for scheduled events like workshops or team days.

However, mandatory attendance does not automatically mean a full return to the office. For example, companies can define two mandatory office days per week and allow mobile work on the remaining days. The decisive factor is how the place of work and mobile work are stipulated in the employment contract, works agreements, collective bargaining agreements, or internal policies.

This article explains mandatory office attendance with a focus on Germany. Separate labor law frameworks apply to Austria, Switzerland, and other EU countries.

What does mandatory attendance mean?

In a work context, mandatory attendance means that employees must perform their work at a specified time and location. With working from home and hybrid work, this presence is now frequently explicitly regulated by contract.

Mandatory attendance can take various forms:

• full-time work in the office on all regular working days
• fixed office days, for example, Tuesday and Thursday
• a minimum number of office days per week or month (as a percentage or pro-rata)
• event-based attendance for workshops, team meetings, or client appointments
• different requirements depending on the team, role, or activity

Return to office on the other hand, describes the trend of bringing employees back to the office more frequently after a phase of extensive home office use. Therefore, mandatory attendance and "Return to Office" are not the same thing.

Mandatory attendance, office presence, and attendance quotas – what is the difference?

The terms are often used similarly (and frequently confused), but they describe different aspects of office attendance.

• Mandatory attendance: A binding requirement to work at the office or another company-designated workplace at specific times (e.g., three fixed days per week).
• office presenceActual or desired employee presence in the office (e.g., a team working primarily on-site on Wednesdays).
• On-site daysSpecific days on which employees or teams work on-site (e.g., every Tuesday is a designated team day).
• On-site attendance rateA metric for the proportion of time spent in the office within a given period (e.g., 60% office attendance per month).

An on-site attendance rate is therefore initially a metric or target. Only when it becomes a binding rule can it become part of a mandatory on-site policy.

Is there a general mandatory on-site policy in Germany?

There is no legal requirement in Germany that employees must work a certain number of days in the office. Conversely, there is currently no general legal right to mobile work or working from home. The Federal Ministry of Labour and Social Affairs points out that a legal regulation for a general right to mobile work does not yet exist.

Which rules apply depends in particular on the employment contract, works or service agreements, applicable collective bargaining agreements, and the employer's right to issue instructions.

Can the employer mandate office presence and a return to the office?

In principle, the employer can, pursuant to Section 106 of the Trade Regulation Act Determine the content, location, and time of work performance at reasonable discretion, provided these points are not already established by employment contract, works agreement, collective bargaining agreement, or legal regulations.

If the place of work is not contractually defined and there is no binding home office policy, an instruction for working in the office can generally be covered by the right to issue instructions. If, however, a specific amount of home office is expressly guaranteed by contract, a conflicting instruction cannot simply override this agreement.

The works council may also be relevant. Section 87 (1) No. 14 of the Works Constitution Act (BetrVG) provides for a right of co-determination regarding the design of mobile work performed using information and communication technology. Depending on the specific regulation, other co-determination issues may be affected. You can find a more detailed overview in the Flexopus article Mandatory office attendance and works council co-determination.

For companies, this means: Before introducing mandatory office attendance, existing contractual regulations and any potential participation rights should be reviewed, and the works council should be consulted.

Why do companies introduce mandatory office attendance?

Companies pursue various goals with fixed office days. Often, it is less about mere presence and more about better overlap between teams and increasing effectiveness.

1. Promoting personal collaboration: Workshops, coordination, and creative processes can be organized more quickly on-site in certain situations.
2. Facilitating informal exchange: Spontaneous conversations happen more easily in the office than in fully digital work environments.
3. Supporting onboarding and knowledge transfer: New employees get to know contacts, processes, and company culture more directly.
4. Making shared team time more predictable:Defined office days prevent employees from being in the office regularly while rarely crossing paths.
5. Using office infrastructure effectively:Meeting rooms, technical equipment, and collaborative spaces can be used effectively on shared office days.
6. Facilitating leadership and communication:For complex projects, in-person coordination can be a valuable supplement to digital formats.

Pros and cons of mandatory office attendance

Mandatory office attendance can structure collaboration, but it also limits spatial flexibility.

The latter point is often underestimated in hybrid offices. If multiple departments or teams choose the same days to be in the office, there must be sufficient workstations, rooms, and parking spaces available.

Our experience at Flexopus shows that the policy alone does not solve the organizational challenge. Employees need transparency regarding who is on-site and when, as well as which resources are available. This predictability is a central component of functional hybrid offices. Flexopus supports this by managing desk bookings, office attendance, and team coordination. Transparency and the right change communication are essential here.

How should mandatory office attendance be introduced?

A new attendance policy should be understandable, predictable, and tailored to the actual work being done. Here is a short checklist:

• Clearly define the purpose of office days
• Involve teams and, if applicable, the works council at an early stage
• Clearly document rules regarding frequency, exceptions, and planning
• Combine shared days with workshops, coordination meetings, or team formats
• Ensure sufficient workstations, meeting rooms, and other resources
• Review the policy after a trial period and adjust as needed

If you would like to encourage office attendance more through shared formats, you can find concrete examples in our article Team events to strengthen office presence.

What are the alternatives to rigid mandatory attendance?

Not every company needs fixed office days for the entire workforce. Hybrid work models can be organized in a more nuanced way:

• Team days:Teams designate a common day.
• Monthly quota:Employees complete a defined number of office days within a month.
• Event-based presence:Attendance is scheduled for workshops, project kick-offs, onboarding, or important meetings.
• Team-autonomous models:Teams decide for themselves when in-person collaboration is beneficial.
• Voluntary office presence:Companies create attractive conditions without fixed attendance quotas.

The right approach depends on tasks, team structure, and office space. Hybrid work offers many advantages. 

With Flexopus as Desk sharing software employees can book desks, meeting rooms, and parking spaces in advance and see who is working in the office on any given day. This provides companies with a predictable foundation for hybrid work without having to manage attendance solely through rigid rules.

A practical example is provided by the success story of the digital agency Banauten, which has been using Flexopus for its hybrid work model since 2020. Because there were times when a permanent desk was not available for every person, workstations were booked in advance. This allowed rotating project teams to sit together as needed. The use case demonstrates how office presence and available resources can be organized together in a hybrid work model.

Conclusion: Mandatory office attendance requires a clear purpose

Mandatory office attendance can structure shared office hours, but it is not an end in itself. The deciding factor is whether being in the office provides a concrete benefit for collaboration, communication, or specific workflows. Equally important are clear rules and an organization that ensures suitable workstations and rooms are available on office days.

Instead of mandating as many office days as possible across the board, companies should evaluate which form of office presence suits their tasks and teams. Between a full-time office mandate and complete freedom of location, there are numerous hybrid models that combine commitment with flexibility, ensuring an efficient and happy team.
