The Invisible Tax
The Invisible Tax
Favoritism does not announce itself.
It does not show up in the employee handbook as a policy violation. It does not appear on a performance review. It does not get flagged in a 360 or surfaced in an all-hands meeting. It moves through an organization quietly, below the visible line of leadership behavior, and by the time the damage is measurable, it has already been paid for.
That is what makes it dangerous.
Most leaders who play favorites are not doing it on purpose. That is not a defense. It is a diagnosis. And it matters, because a leader who cannot see the problem cannot fix it.
How It Starts
George Graen and Mary Uhl-Bien spent decades studying the relationship between leaders and their direct reports. What they found became one of the most replicated findings in organizational research. Leaders do not treat everyone the same. They develop higher-quality relationships with some people, more communication, more trust, more access, more latitude, and lower-quality relationships with others. Graen and Uhl-Bien called this Leader-Member Exchange, or LMX. The inner circle became the in-group. Everyone else became the out-group.
Here is what the research did not excuse: when the line between those two groups is drawn by personal affinity rather than performance or potential, it stops being relationship differentiation and starts being favoritism. Same dynamic. Different driver. Entirely different consequence.
The leader usually cannot see where that line is drawn or why. They experience the in-group relationships as natural. Easy. Productive. They are more comfortable with those people, more aligned, more energized after the conversation. They call it chemistry. They call it fit. What they are often describing is a mirror. People who think like them, respond like them, and reflect their own instincts back at them in a way that feels like confirmation.
That comfort is not leadership. It is preference. And preference at the leadership level costs the entire team.
What the Team Sees
While the leader is experiencing chemistry, the rest of the team is running a calculation.
They are watching who gets the interesting projects. Who gets pulled into the room when the real decisions are made. Who gets grace when they miss a deadline, and who gets a conversation. Who gets developed, and who gets managed. They are cataloging every data point with a precision the leader would find unsettling if they knew it was happening.
Research from Harvard Business School's Amy Edmondson on psychological safety makes this clear. Teams are continuously assessing whether the environment is safe enough to take risks, raise concerns, and invest full effort. What they are actually measuring is whether contribution is the currency. When favoritism is in play, the answer is no. The currency is proximity. And the team adjusts accordingly.
That adjustment is the invisible tax.
It shows up as reduced discretionary effort from out-group members. Why go the extra distance when the extra distance does not change your standing? It shows up as information hoarding. Why surface a problem or a good idea when someone else will get credit for it? It shows up as disengagement that looks like competence. The employee who does exactly what is asked, nothing more, and is quietly planning their exit.
The 2020 Harvard Business Review report on favoritism found that 75% of workers say they have witnessed it in their workplace. Twenty-three percent said it directly caused them to leave a job. Those are not edge cases. That is a structural drain running inside most organizations, funded by a leadership behavior the leader is not aware of and the team cannot afford to name out loud.
The Cost That Never Shows on a Dashboard
This is the part that makes favoritism especially destructive from a servant leadership standpoint.
Servant leadership is built on a specific belief: that the leader's primary job is to create conditions where other people can do their best work. Not to be the most important person in the room. Not to build a loyal inner circle. To clear the path, remove the friction, and make it possible for the people they lead to grow, contribute, and thrive.
Favoritism does the opposite. It creates friction for the out-group that the leader never feels directly. The tax is paid by the people who needed the most support and received the least. And because they are usually not in a position to tell the leader what it is costing them, the bill comes due in attrition, in performance gaps, in a culture that looks functional from the top and feels broken from the inside.
Robert Folger and Russell Cropanzano's research on organizational justice identifies three dimensions workers evaluate continuously: whether outcomes are fair, whether processes are fair, and whether they are being treated with dignity. Favoritism violates all three at once. The California Institute of Technology's neuroscience research adds a layer that leaders should not dismiss lightly. The brain processes perceived unfairness the same way it processes a physical threat. The anterior insula, the region associated with disgust and social pain, activates when people believe they have been treated unjustly. This is not a morale issue. It is a biological response to an environment the brain has classified as unsafe.
The leader who plays favorites is not just making some people feel bad. They are triggering a threat response in a portion of their team every single day. And they are doing it invisibly, with no feedback loop, no dashboard metric, and no performance review that names what is actually happening.
The First Step Is Seeing It
The work of servant leadership begins with awareness. Not awareness of strategy or market conditions or organizational structure. Awareness of what your leadership is actually creating in the people around you.
That means asking different questions. Not "who is performing well?" but "who am I investing in, and why?" Not "is my team engaged?" but "which members of my team would tell me honestly if something was wrong, and which ones would not?" That gap, between who can speak freely and who cannot, is often a direct map of the in-group and the out-group the leader has built without intending to.
Favoritism is invisible to the leader because the leader is inside it. It is visible to everyone else because they are living in it.
The first condition for fixing it is being willing to look.
