The Doctrine and Its Disguise
"Do more with less." It appears in board presentations, town halls, and strategic planning documents with the confidence of received wisdom. It is framed as necessity, as agility, as the modern condition of competitive enterprise. It is, in practice, the decision to reduce headcount and budget while keeping or expanding expectations, and to distribute the resulting gap across the people who remain.
This is not a peripheral trend. Gallup's 2025 State of the Global Workplace report found that the average number of direct reports per manager rose to 12.1 in 2025, up from 10.9 in 2024 and representing a fifty percent increase from 2013 when Gallup first began collecting the figure. Simultaneously, the same research identifies a structural boundary that organisations are routinely ignoring: managers are most effective when they spend no more than forty percent of their time on individual contributor work. Organisations are widening spans of control without reducing the individual workloads sitting on top of those spans, which means they are not streamlining the management function. They are quietly dismantling it while maintaining its title and salary band.
The old adage is plainspoken and correct: you cannot ride two horses with one ass. A leader whose attention is split between managing people and executing technical deliverables is not doing both roles. They are doing two partial versions of each, and neither role receives what it actually requires. The team is not being led. The technical work is not being done to the standard that a dedicated practitioner would bring. And the person in the middle, absorbing the impossible expectations of both, is paying a price that no performance review will ever accurately capture.
The Cognitive Science of Divided Attention
The argument that effective leaders can simultaneously manage teams and perform individual contributor work at a high standard is in direct conflict with what cognitive science knows about how human attention works. Daniel Kahneman described this boundary directly: the total amount of attention available at any given time is fixed, and deploying it in multiple directions simultaneously does not multiply it. It divides it. Studies have found that multitasking of this kind can reduce effective productivity by up to forty percent, not because people are performing fewer tasks, but because each task is being performed in a state of partial attention.
Effective people management requires sustained relational attention: the capacity to observe team members across time, to notice changes in behaviour and performance, to hold developmental conversations that require genuine listening. These are not tasks that can be completed in the gaps between a coding sprint or a case review. A director who is spending the morning resolving a production incident, the afternoon on a client case, and the evening reviewing a strategic document is not in a cognitive state that allows them to provide the quality of leadership attention their team requires. They are in a state of chronic context-switching that the research consistently identifies as a significant predictor of decision fatigue, reduced empathy, and impaired judgment.
The Numbers Behind the Breaking Point
Gallup's 2025 State of the Global Workplace report found that global employee engagement fell from twenty-three percent in 2023 to twenty-one percent in 2024, a two-point decline that matches the drop recorded during COVID-19 lockdowns. The cost of this disengagement was estimated at four hundred and thirty-eight billion dollars in lost productivity. The primary driver was a drop in manager engagement, which fell from thirty percent to twenty-seven percent in a single year. Among managers under thirty-five, the drop was five percentage points. The Eagle Hill Consulting Workforce Burnout Survey found that more than half of the United States workforce reported experiencing burnout. The Cariloop 2025 report found that eighty-two percent of managers reported experiencing burnout, exceeding the rate for entry-level employees.
The Physiology of Chronic Overload
The human body has a stress response system designed for acute, time-limited threats. What it was not designed for is the condition that chronic workplace overload creates: a state in which the pressure never fully resolves, the cortisol never fully clears, and the recovery never fully occurs. The Mayo Clinic's research confirms that long-term activation of the stress response system disrupts nearly every bodily process. Research published in Psychosomatic Medicine found that burnout was associated with a measurably increased risk of coronary heart disease. The consequences of chronic workplace overload do not remain at the office. They travel home in the nervous system of the person who carries them, and they change how that person is present in every other domain of their life.
The Management Pipeline Is Failing Because People Are Watching
A 2023 survey found that only thirty-seven percent of individual contributors wanted their manager's job. Forty percent cited expected stress and pressure as the primary deterrent. Robert Walters found in 2024 that seventy-three percent of Generation Z workers preferred to advance as individual contributors rather than as managers. The pipeline is not failing because there is a shortage of talented, capable people. It is failing because talented, capable people have sufficient information to make an informed assessment of what leadership currently involves, and what it currently involves is not attractive.
The Standard Worth Holding
Reducing spans of control where individual contributor demands are high, protecting leadership time from technical deliverables as a matter of structural policy, providing genuine and regularly delivered management training, and measuring the health of management as a function rather than only measuring the outputs of the teams below it are not radical interventions. They are what the research has consistently recommended for decades. They are also consistently sacrificed in the name of cost efficiency. The person currently occupying two roles simultaneously is not failing. They are being failed. The old adage survives because it is true. You cannot ride two horses with one ass. The organisations that design their structures to prevent that choice from ever becoming necessary are not being generous. They are being accurate about what human beings can sustain, which is the only intelligence that ultimately matters in the design of any system that depends on human beings to run it.
