Remote work loại bỏ thời gian đi lại, giảm các cuộc trò chuyện không cần thiết và cho phép nhân viên tập trung hơn. Công ty nên đánh giá bằng output, không phải bằng việc nhân viên có ngồi trong văn phòng 8 tiếng hay không. Người lao động không phải mất hàng giờ mỗi ngày để đi lại, đồng thời giảm chi phí ăn uống, di chuyển và nhiều chi phí liên quan đến việc đến văn phòng. Phía công ty cũng có thể giảm nhu cầu về văn phòng, điện, bàn ghế và các chi phí vận hành

I agree that offices can make spontaneous collaboration and mentorship easier. But you're treating those benefits as if they can only exist when everyone is physically present. They can't. Teams can create intentional mentoring, open video channels, pair programming, virtual brainstorming, and regular one-on-one sessions. It may require more structure, but that doesn't make remote work inherently worse. And the fact that junior employees can learn by overhearing conversations isn't necessarily an argument for the office. It means companies need to build better systems for knowledge sharing. Relying on someone accidentally hearing the right conversation is hardly a reliable training strategy. You also mentioned that productivity stays okay for solo tasks while complex projects suffer. But that's an argument for choosing the right work model, not automatically choosing the office. A complex project might benefit from an in-person workshop for a few days, while the rest of the work can happen remotely. That's exactly where hybrid work makes more sense. And let's not ignore the opposite problem: offices create their own collaboration costs. Constant interruptions, unnecessary meetings, commuting fatigue, and open-office distractions can make deep work harder. Being physically close doesn't automatically mean people communicate better or trust each other more. So yes, being in the same room can be valuable. But valuable doesn't mean mandatory. If a team can achieve the same goals remotely, forcing everyone into an office every day is difficult to justify. The best workplace should be determined by the work—not by tradition If your strongest argument for the office is that employees might overhear something useful, then you're defending an environment where collaboration happens by accident. Remote work asks companies to make collaboration intentional—and that's not a weakness.

But I think you're making the opposite mistake: you're treating spontaneous interaction as if it automatically produces better collaboration. Sometimes it does, but sometimes those ‘casual conversations’ are interruptions, office politics, or information that never gets documented. Being physically present doesn't guarantee innovation or trust. And remote work doesn't treat employees like isolated output machines. People can build relationships through regular video calls, team chats, virtual brainstorming, mentoring sessions, and occasional in-person meetups. The difference is that remote teams have to be more intentional about it. You also say culture and innovation can't be measured in deliverables. That's fair—but that doesn't mean we should assume the office creates them. If a company's culture depends entirely on people accidentally overhearing each other, then the company hasn't built a very robust culture in the first place. Good organizations can deliberately create opportunities for mentoring and collaboration regardless of location. And there's another side you're overlooking: remote work can actually improve collaboration by giving companies access to people who aren't able or willing to relocate. A company can build a team around talent rather than geography. That's potentially a much bigger advantage than having everyone share the same building. So I'm not claiming remote work is perfect. I'm saying your argument proves that some activities benefit from being together, not that employees need to be in an office every day. If brainstorming or team-building genuinely works better face-to-face, meet in person for those activities. But forcing everyone into an office five days a week just to preserve the possibility of spontaneous interaction isn't necessarily the most effective solution. Better doesn't simply mean cheaper. It means achieving the goals of the organization with the least unnecessary friction. If people can think, collaborate, learn, and build trust remotely, then the office should be an option—not a requirement.
