International mobility programs deliver their greatest value when leaders treat them as culture-building experiences, not simply location flexibility. A temporary work-abroad opportunity can absolutely be exciting for employees, but its organizational impact runs deeper: it helps people build relationships across offices, experience different working rhythms firsthand and strengthen the kind of cross-agency collaboration that makes a global network more connected. When designed intentionally, those benefits do not end when the employee returns home. They come back with them.

For managers and talent leaders, that means the real question is not whether an employee should spend time in another office. It is how to make that experience purposeful before departure, meaningful while they are away and reusable once they return.

The clearest value often starts with something deceptively simple: proximity. When employees spend time in another office, they stop imagining how another market works and start seeing it for themselves. They observe how people begin the day, how teams interact, how quickly conversations happen and what kinds of connections form naturally in the office. Those details matter because culture is rarely learned through org charts or slide decks. It is learned in the everyday.

That is why temporary mobility can be such a powerful leadership tool. An employee who has worked in more than one office develops context that is hard to gain remotely. They begin to understand not just what colleagues in another market do, but how they work, how they communicate and what they prioritize. That kind of firsthand exposure builds empathy and reduces the friction that can exist between teams separated by geography.

It also gives leaders a practical way to strengthen collaboration across Publicis Groupe. In one example, the experience of being in a different office made cross-agency connection far more visible. Employees saw colleagues from different agencies share a building, build relationships and come together in ways that made the "Power of One" feel tangible rather than abstract. For leaders, that is an important insight. Mobility programs can help people see the network as a living ecosystem, not a collection of separate teams. When employees return with a stronger sense of how agencies connect, they are often better positioned to collaborate more openly across boundaries.

The informal moments matter, too. In one office, the workday rhythm included real lunch breaks, catch-ups over coffee and regular interaction beyond immediate project teams. Those moments may sound small, but they shape how knowledge travels. Casual conversations create visibility, trust and unexpected connection. They help people learn what is happening across the business and maintain working relationships that would otherwise stay purely transactional. Leaders should pay attention to this because international mobility is one of the few ways employees can experience those cultural mechanics directly. Seeing another office’s rhythm firsthand can challenge assumptions about productivity, collaboration and what healthy team connection looks like.

To turn that insight into lasting organizational value, leaders need to support employees in three phases.

Before the experience: define the purpose

A temporary relocation should begin with intention. Managers should work with the employee to identify a few clear goals tied to culture, collaboration and learning. That might include building relationships with a local team, spending time with adjacent functions, observing how another office structures the workday or identifying opportunities for cross-agency partnership. The point is not to overengineer the experience. It is to make sure the time abroad is anchored in more than logistics.

This is also the moment to prepare the receiving office. A successful experience depends on more than approval. It depends on welcome. Leaders can help by making introductions in advance, identifying people the employee should meet and encouraging local colleagues to include them in the real rhythm of the office rather than treating them as a visitor passing through. The more quickly someone feels part of the environment, the more likely they are to form relationships that last.

During the experience: encourage immersion, not just attendance

Once the employee arrives, managers should resist the temptation to measure success only through output. Of course the work still matters. But the broader value comes from immersion. Leaders should encourage employees to be present in the office, build relationships across teams and notice the subtle patterns of how the workplace functions.

That might mean meeting colleagues outside their usual day-to-day circle, joining informal office moments or spending time with teams from other agencies in the building. It may also mean being open to differences rather than judging them. A different pace, a different style of conversation or a stronger emphasis on communal breaks can all become sources of insight.

This phase is especially important because it is where stereotypes begin to fall away. Employees often discover that another office operates differently than they expected, and that difference can be instructive. Exposure to another market’s norms helps people become more adaptive communicators and more thoughtful collaborators.

After the experience: bring the value back into the business

The return is where many mobility programs lose momentum. If the experience ends as a personal memory, the organization misses much of the benefit. Talent leaders and managers should create a simple path for employees to share what they learned.

That does not require a formal playbook. It can be as practical as a team discussion, a short internal share-back or a conversation with peers and leaders about what the employee observed. What mattered about the office culture? What surprised them about the way people collaborated? What ideas could improve connection at home? What relationships were formed that could now support broader work across teams or agencies?

This is also the time to keep those new connections alive. If an employee built relationships across offices or agencies, managers can help convert them into continued collaboration. Invite the employee to stay connected to colleagues they met abroad. Involve them in projects where that network perspective is useful. Treat them as someone who can bridge markets, not simply as someone who spent time away.

For talent leaders, the broader takeaway is clear. International mobility programs are not just employee benefits. They are culture infrastructure. They help people experience the business beyond their home office, build trust across markets and return with a wider view of how collaboration really happens.

When leaders support these experiences intentionally, the result is more than a memorable assignment abroad. It is a stronger, more connected organization—one where employees understand each other better, work across boundaries more naturally and bring the full power of the network back into the everyday.
