The Accidental Manager

Why Your Best Performers Are Failing at Leadership

Picture this: Susan, a new product developer, is a standout employee in your organization. In just 18 months, she has consistently surpassed her goals, introduced innovative ideas, and recently salvaged a crucial relationship with a long-standing client. Her teammates appreciate working alongside her, and she is widely respected across various departments. 

When a leadership position became available, promoting Susan seemed like the obvious choice…until reality set in. Four months into her new role, Susan finds herself exhausted, working 55 hours a week because she is handling much of her team’s workload. Her direct reports are becoming frustrated and disengaged. The limited time Susan spends “engaging” with her team is focused on resolving issues with a few challenging employees, leaving her without meaningful interaction with her two top performers. 

This situation is all too familiar. As business leaders, we often mistake exceptional individual performance for effective leadership ability. We promote our best contributors to leadership roles but neglect to equip them with the necessary resources and tools to succeed. Months later, we question if the promotion was a mistake. Susan questions if she is even a good product developer as she drowns in people wrangling. The reality is that excelling at individual tasks and leading a team requires entirely different skill sets. Promoting top performers without preparing them for leadership responsibilities sets managers and their teams up for failure. 

How Did We Get Here:

Finding and retaining high-performing employees takes immense time and effort. In 2025, SHRM says the median time-to-fill is roughly a month and a half for both executive and nonexecutive positions, with more time for more specialized roles. Once employee contributions become invaluable, we naturally want to reward them and keep them engaged, so we promote them into management. 

But there are three major problems with this response: 

• We lack alternative reward mechanisms. Often, management is the only available next step for a top performer. By creating "Senior Contributor" tracks, we allow experts to advance their careers and earn more without forcing them to change their core function from doing to managing.

• We fall for the "Halo Effect." We mistakenly believe that because someone is exceptional at one thing, they will naturally excel at everything. We let their stellar track record blind us to the fact that leadership requires an entirely different set of competencies.

• We make costly assumptions. We assume we know what motivates them or what career path they actually want. Worse, we assume they can just "pick up" leadership skills on the fly. We would never send an installer to a job site without tools or a programmer to a desk without a laptop, yet we routinely send new leaders into the field with nothing but a new title and a prayer.

  
  

When we divvy out the promotions, acting on these assumptions, we create accidental managers. According to the Chartered Management Institute’s survey of 4,500 workers, 82% of bosses are “accidental managers.”  Of these accidental managers, many of their employees are less satisfied with their jobs and quitting. Many of these same managers, not feeling confident in their own management, plan to vacate their roles.

The Hidden Cost of the Accidental Manager

Bringing in a new leader for a team presents considerable risk. New leaders are usually highly skilled, like Susan, which can make delegation and avoiding micromanagement difficult. This may alienate other highly engaged top performers. The incoming leader might experience burnout as they struggle to manage their new role without adequate support, sometimes continuing their previous responsibilities while taking on added leadership duties. 

Over time, morale may decline, and the organization could not only lose its strongest contributor, but also inadvertently cause departmental bottlenecks and reduced productivity. Moreover, senior executives in the C-Suite may question the judgment of the leader who appointed the new manager and wonder at the misguided decision. 

Here is the actual cost, disengagement. In 2024, decreased employee engagement, primarily a product of accidental managers, cost the world economy $438 billion in lost productivity. Based on Gallup’s 2025 State of the Global Workplace report, the primary factor driving disengagement is managers.

The Solution: Management Training to Nurture Leadership Growth

When companies offer training to emerging leaders before they step into management roles, they set the stage for optimal success. This means supporting Susan by teaching leadership values, before sending her to the wolves. By making leadership development an integral part of organizational culture, a steady stream of future leaders is naturally developed. Key abilities such as delegation, communication, conflict resolution, coaching versus executing, navigating tough conversations, and providing consistent feedback are hallmarks of effective leaders. 

Only 44% of managers report receiving formal training for their role. That leaves 66% of managers needing coaching. Management training itself can raise productivity by 17% through improved quality and efficiency. Employer-provided training for managers increases well-being from 28 to 34%.

Ongoing investment in leadership training empowers current leaders to mentor and shape the next wave of talent. Strengthening these skills, embracing fresh strategies, and nurturing both seasoned and new leaders not only elevate the organization’s workforce but also boost profitability, enhance employee retention, and establish the company as an employer of choice. 

By fostering talent from within, skilled employees recognize clear paths for advancement, leading to increased loyalty and tenure. Outstanding managers aren't simply born, they're cultivated through dedicated time and resources, learning from successes and setbacks, and mastering the art of team engagement. Accident prevention is everyone's responsibility. Our aim is to equip leaders with the tools not just to guide their teams, but to enable them to flourish.
