Radical thought for the day: Will mentors replace leaders in a hybrid world?
Here is a proposition worth sitting with: the leadership model most organizations still rely on was designed for a world that no longer exists.
The 20th-century organization had a logic to it. Authority resided in the hierarchy. Knowledge accumulated at the top and flowed downward through layers of management. Loyalty was earned through tenure, and careers were predictable enough that a senior manager could point to their own trajectory and say, with reasonable confidence, "Do roughly this." That model worked because the conditions it depended on were stable: permanent employment, fixed locations, long-term teams, and a clear line between who knew things and who needed to be told them.
Strip those conditions away, and the model stops working. Not gradually, not in isolated pockets—it stops working as a general proposition.
The organization has changed; the leadership model hasn't
The 21st-century organization asks people to operate very differently. High-performing individuals move between projects, functions, and geographies at a pace that previous generations of managers never experienced. Teams form, deliver, and dissolve. Roles are temporary. Locations are negotiable. The colleague sitting three desks away last quarter is now working from a different time zone or a different company.
What does not change is what organizations need from their people: discretionary effort, alignment with organizational goals, commitment that goes beyond the transactional, and the kind of loyalty that makes talented people choose to stay when the market is offering them alternatives.
The problem is that hierarchical authority -- the mechanism most organizations still rely on to generate those outcomes -- is poorly suited to transient environments. You cannot direct someone's commitment. You cannot instruct loyalty into existence. These are things people choose to give, and they tend to give them to people and organizations that invest in their growth rather than simply deploying their skills.
That distinction matters more than it used to. When people expected to stay in the same organization for decades, the implicit bargain was clear enough. Now, when the average tenure in many professional roles is measured in years rather than careers, the bargain needs to be made explicit and renewed continuously. The manager who treats a high-performing team member as a resource to be allocated will find that resource has been allocated elsewhere before long.
What hybrid working revealed
The shift to hybrid and remote working accelerated a problem that was already developing. When offices emptied during the pandemic, organizations discovered that a significant proportion of professional development was happening informally, without anyone arranging or budgeting for it. The corridor conversation with a senior colleague. The spontaneous debrief after a difficult client meeting. The coffee queue exchange that turned into career advice nobody had planned to give.
None of this appeared on any learning and development budget, yet it was doing real work: building relationships, transferring knowledge, giving junior employees visibility with senior ones, and providing the kind of informal guidance that formal programs rarely replicate. As offices emptied, that texture disappeared. When offices partially refilled, it did not fully return, because the conditions that generated it shared physical presence, predictable daily rhythms, and accidental proximity are now only intermittently available.
The organizations that responded well to this recognized that the office's informal developmental infrastructure needed to be replaced with something more deliberate. Structured mentoring is one of the most direct substitutes available. It intentionally recreates the kind of relationship that used to develop accidentally.
The case for mentoring as a leadership model
This is where the radical part of the proposition arrives. In transient, hybrid environments, mentoring may be more effective than conventional leadership in generating the organizational outcomes that matter most.
Consider what a good mentor does. They invest time in understanding what a person is trying to achieve, not just what the organization needs them to deliver. They provide honest feedback that serves the mentee's development, not just the manager's convenience. They build a relationship that creates genuine psychological safety -- the kind that allows someone to admit a mistake, ask a question, or share a concern without calculating the career risk. And they do this consistently, over time, in a way that builds trust rather than demanding it.
These are not soft outcomes. Research on mentoring programs consistently shows higher retention, stronger internal communication, and more resilient leadership pipelines in organizations that invest in structured mentoring. The reason is not complicated: people stay where they feel developed, and they commit where they feel seen.
In this framing, the mentor is not replacing the leader. They are doing something the traditional leadership model can no longer do: building the loyalty, alignment, and commitment that transient organizational structures erode.
The structural argument
There is a structural case here as well as a cultural one. Hierarchical authority operates through positional power—the ability to direct, reward, and sanction. That power is meaningful when the relationship is long-term, and the stakes of the power dynamic are high. When someone is on a project team for six months, the team leader's positional power is considerably weaker. The team member knows it, and so does the leader.
Influence, by contrast, travels well across temporary structures. A mentor who has invested in someone's development over time has a kind of authority that positional power cannot replicate -- not because it is exercised, but because it has been earned. That earned authority does not depend on the organizational chart. It survives team, location, and role changes. It can, if the relationship is strong enough, survive someone leaving the organization entirely.
Chapter 17 of From Manager to Mentor makes a related point about virtual and hybrid mentoring specifically. The core skills of good mentoring -- listening carefully, asking the right questions at the right moment, building trust without physical presence -- travel well across a screen in a way that directive management does not. A manager who relies on visibility and proximity to maintain authority struggles in a hybrid environment. A mentor who relies on relationship quality does not.
The practical question
None of this means that organizations should abolish management structures or that leadership is no longer relevant. Decisions still need to be made, priorities set, and accountability maintained. The argument is more specific: that the leadership behaviors most likely to generate commitment, retention, and discretionary effort in a hybrid, project-based, talent-mobile world are mentoring behaviors -- and that organizations which recognize this early will have a structural advantage over those still waiting for the office to feel like 2019 again.
For individual managers, the practical question is straightforward. When someone on your team is deciding whether to stay or go, what is the quality of the relationship that will tip the balance? Not the compensation package, not the title -- those are table stakes. The relationship. The sense that someone senior has invested in their growth, told them the truth, and paid attention to where they are going rather than just what they are currently delivering.
That is not a description of a manager. It is a description of a mentor.
The radical thought, it turns out, is not that radical at all. It is simply that the skills the moment requires have a name, and the organizations willing to take them seriously are the ones that will find out what that name is worth.
