Office hours — everyone deals with them. But how did they actually originate, and how do you approach them today? Are 9-to-5 working hours outdated, or are they here to stay? The way we work has changed significantly in recent years. Working from home, hybrid working, and flexible hours have become increasingly common. Still, office hours continue to play an important role. So how does that work exactly? You’ll find out here.
What are office hours?
Office hours refer to the times when offices are open and available by phone. Typically, these are weekdays (Monday to Friday) between 9:00 AM and 5:00 PM. Lunch breaks usually take place between 12:00 PM and 1:00 PM, and many companies also allow for coffee breaks in the morning and afternoon.
Office hours do not apply on national holidays and may vary by company or sector. Although more organizations are adopting flexible working hours, these traditional hours still serve as the standard — especially when it comes to availability.
How did office hours originate?
Office hours have existed for over 100 years. At the time, parliament approved fixed working hours of eight hours per day. This emerged during the rise of factories, offices, and workshops.
The day was divided into three parts: eight hours of work, eight hours of leisure, and eight hours of sleep. This structure provided clarity and balance.
Even though we now work more flexibly and often remotely, this structure is still widely used — not only for employees, but also to provide clarity for customers.
What are the advantages of fixed office hours?
Office hours offer several advantages. First, there’s availability. Companies that operate during regular office hours are easily reachable for customers, and many people still expect businesses to be available during these times.
They also support collaboration. When everyone works roughly the same hours — whether in the office or online — communication becomes easier. Quick check-ins, meetings, or decisions can happen without delay.
Finally, fixed office hours provide structure. Employers can more easily track working hours and manage team planning.
Are there disadvantages to fixed office hours?
Yes, fixed office hours also have downsides. The most notable is productivity. Not everyone performs at their best at the same time of day. Morning people thrive early, while others are more productive later in the day.
Time differences can also be a challenge. If you work with international clients or remote teams, standard office hours may not align well. And in a world where working from home is increasingly normal, a strict 9-to-5 schedule feels less natural for many people.

What is flexible working?
Alongside fixed office hours, flexible working has become increasingly common. This means you’re not tied to fixed hours and can structure your workday yourself.
Whether you prefer working in the morning, evening, or spread throughout the day — you choose what works best for you. This approach is especially common in combination with hybrid working, where you split your time between home and the office.
What are the pros and cons of flexible working?
Flexible working offers a high degree of freedom. You can align your working hours with your own schedule and that of your clients, often leading to better balance and increased productivity.
However, it also comes with challenges. Many companies still operate within standard office hours and are only reachable during those times. Working outside these hours can make communication more difficult.
Collaboration also requires more coordination. When colleagues work at different times, scheduling meetings can become more complex. Without clear agreements, it’s easier to misalign.
Office hours today: what do we see in practice?
The biggest change? It’s no longer a black-and-white story. Where 9-to-5 used to be the norm, companies are now increasingly choosing a middle ground. Office hours still exist, but they are applied more flexibly. Teams often work together at fixed times, either in the office or online, while also having the freedom to manage their own schedules. This combination offers both structure and flexibility.
You know when colleagues are available, but also have the freedom to work when you’re most productive. Office hours have become more flexible, but still remain an important foundation for collaboration and availability.
Is flexible working the future?
The question is whether flexible working is the future. While it offers many advantages, it also has its limitations. For some industries, flexible working is ideal. For others, fixed office hours remain practical and sometimes necessary.
What’s clear is that our perspective on working hours has changed. Flexibility plays a bigger role, but office hours haven’t disappeared. The traditional 9-to-5 hasn’t gone away — it has simply evolved.
