Saying "I have a global team" sounds like the kind of thing almost any leader would be proud of. What is discussed far less often is what that actually means for schedules and the way working time is distributed. In an international team, there are almost never hours that are equally convenient for everyone. Ten in the morning for one office may mean the end of the workday for another and an uncomfortably early start for a third. Technically, it is usually possible to find an open slot in everyone's calendar. But the compromise is rarely distributed evenly: someone inevitably has to give up more convenience and adjust to everyone else.
When meetings like this happen only occasionally, they remain a manageable part of working across countries. The problem begins when the same employee or region spends weeks or months repeatedly reorganizing the workday around international calls. At that point, the time difference stops being a simple fact of geography and becomes an additional form of workload-unstructured and sometimes barely visible to either employers or the teams themselves.
The scale of the issue is growing alongside international collaboration. According to Microsoft, 30% of meetings now involve participants across multiple time zones, up eight percentage points from 2021. Over the course of a year, the number of meetings beginning after 8:00 p.m. in an employee's local time increased by 16%, while the number of messages sent outside standard working hours rose by 15%.
Distributed teams give companies access to talent and markets far beyond a single city or country. But that freedom creates a new management challenge: ensuring that the benefits of operating globally are not consistently paid for with the personal time of the same group of employees.
The Cost of Time-Zone Differences
There is no universally convenient point where time zones overlap. If a team works across Dubai, London, New York, and Singapore, for example, someone will periodically have to start earlier or finish later. The compromise itself is unavoidable. The real problem begins when it repeatedly falls on one particular region.
The default reference point is often the schedule of the headquarters or the company's largest office. A 10:00 a.m. meeting feels completely normal to the person scheduling it, so the fact that another employee has to join in the evening gradually stops being treated as an additional burden. After several months, a late call simply begins to look like a routine part of working on an international team.
Research published in Organization Science helps show how employees themselves compensate for this distance in time. The authors analyzed communication among 12,038 employees at a large multinational company whose workforce was spread across 167 cities in 48 countries. The greater the time difference between colleagues, the more often work-related communication shifted outside employees' local working hours. The effect was especially pronounced in tasks that required close collaboration and could not easily be replaced by simply passing information from one person to another.
This creates a paradox: international teams can appear highly synchronized largely because employees stretch their own workdays to make that synchronization possible. A shared meeting does not disappear because colleagues are separated by five or eight hours. Someone simply moves part of the work into the morning or evening.
People, however, do not have the same ability to adapt to this kind of schedule. In the same study, women were on average less likely to move synchronous work communication outside standard working hours, as were employees in countries with stricter legal limits on working time. The authors note that differences in people's ability to give up personal time for work may ultimately create inequalities in professional outcomes.
There can be many reasons for this difference, and the data does not allow it to be attributed solely, for example, to family responsibilities. For employers, the more important point is that evening availability is not an equal resource for every employee. One person may be able to return to work regularly after 8:00 p.m.; another may have responsibilities at that time that simply cannot be moved. A willingness to work later than colleagues should therefore not become a proxy for greater commitment.
When Availability Becomes a Career Advantage
In practice, a late meeting requires much more than the 45 minutes shown on the calendar. If a call is scheduled for 9:00 p.m., part of the evening has to be organized around it: you cannot travel too far, you need to be back at your laptop on time, and personal plans have to be wrapped up by a certain hour. And once the call is over, work mode does not always switch off at the same moment as the camera.
When this becomes a regular pattern, it creates a split workday. An employee completes most of their work during normal hours and then returns to it again in the morning or evening because that is when another part of the team is available. Formally, this may amount to only a few additional calls. In reality, the boundary between work and personal time becomes increasingly difficult to define.
But comfort is only one part of the issue. In an international team, time can also affect career visibility. If key discussions take place during headquarters hours, an employee in another region faces a choice: regularly join at inconvenient times or miss part of the live conversation. A meeting summary may explain what was ultimately decided, but it cannot fully recreate the opportunity to ask a question, challenge an assumption, add an argument, or influence the direction of the discussion while the decision is still being formed.
Over time, time-zone differences can therefore affect access to professional context itself. Someone who is present more often in synchronous discussions naturally becomes more visible to colleagues and senior leaders, hears about changes sooner, and participates in more of the informal conversations surrounding a project. For an employee in another time zone, achieving the same level of presence may require a much greater sacrifice of personal time.
Against this backdrop, a culture of constant availability poses a serious risk to long-term productivity and mental well-being. If a "flexible schedule" effectively means a normal workday plus early-morning and late-evening meetings with international colleagues, the flexibility primarily benefits the company. For the employee, working hours simply expand in both directions.
Microsoft describes the broader phenomenon as the "infinite workday": work activity is increasingly extending beyond the traditional boundaries of morning and evening, while cross-regional collaboration is one of the factors contributing to the growth of late meetings. International teams do not create this problem on their own, but they can intensify it significantly when availability begins to be treated as the individual employee's responsibility.
Rules for Working Across Multiple Time Zones
Organizing international work fairly does not mean eliminating early-morning or late-evening meetings altogether. For teams spread across different continents, that is rarely realistic. What matters more is deciding in advance which tasks truly require everyone to be present at the same time-and how the unavoidable inconvenience will be shared.
Define overlap hours. The team should have a clear window during which employees in different regions can reasonably expect synchronous collaboration. This reduces the risk that any open slot in a digital calendar is automatically treated as an acceptable meeting time.
Rotate inconvenient hours. If two offices meet regularly and there is no ideal time for both, early mornings and late evenings can alternate between the two sides. That way, the time difference remains a shared feature of international work rather than a permanent burden placed on one region.
Shift the workday instead of extending it. A required 9:00 p.m. call should not automatically become the ninth or tenth working hour of the day. If an international role genuinely requires regular evening availability, that should be reflected in the schedule: starting later, finishing earlier, or compensating for that time in another way.
Do not turn every interaction into a meeting. Project updates, data sharing, comments on documents, and many approval processes can be handled asynchronously. GitLab, whose team operates across more than 65 countries, explicitly recommends first asking whether a task truly requires a meeting, checking participants' time zones, and creating conditions for asynchronous participation. The company also advises documenting decisions after calls and, when a discussion takes place at an inconvenient time for part of the team, leaving 24-48 hours for additional comments.
This kind of system benefits more than just employees who live farthest from headquarters. When decisions, arguments, and working context are documented rather than existing only in live calls, access to information depends less on who happened to be online at the right moment. This reduces the need for repeated meetings and makes distributed teams more resilient as they continue to grow.
Sometimes companies also have to acknowledge the limits of geographic flexibility. Atlassian's Team Anywhere model, for example, allows employees to work far from traditional offices, but only when the chosen time zone is compatible with the requirements of the role. Even a company that strongly supports distributed work still maintains time-zone boundaries where collaboration would otherwise become too difficult.
International teams will still have early mornings, late calls, and days when employees need to adjust to colleagues on another continent. The difference lies in whether those moments remain an occasional, shared compromise or become a permanent rule for the same group of people.
A global business may operate around the clock. An individual employee's workday does not have to-and should not-do the same.
