Too Many Direct Reports Is Wearing Managers Down

Over the past few years, many companies have removed layers of management to cut costs and speed decisions. The managers who remain often supervise far more people than before. That shift has a cost that rarely appears on an organization chart. A manager with too many direct reports has little time to coach any of them.

What the research shows

Gallup has studied managers and engagement for decades, and its findings are consistent. Managers account for about 70 percent of the variance in team engagement. When managers are disengaged or overwhelmed, their teams tend to follow.

Gallup's 2026 State of the Global Workplace research, which we covered in our report on manager engagement, found that manager engagement has slipped worldwide. The same research points to what helps. Managers who received training were more likely to be thriving, with the share rising from 28 percent to 34 percent. When training was paired with ongoing coaching, the share rose to 50 percent.

Gallup also reports that coaching programs can lift employee engagement by as much as 22 percent, and that engagement tends to decline as a manager's span of control grows. In organizations Gallup identifies as best practice, 79 percent of managers are engaged.

Why span of control matters

A manager has only so many hours. Regular one-on-one meetings, feedback, development conversations, scheduling, problem solving and administrative work all compete for time. With six or eight direct reports, a manager can hold weekly check-ins and still do other work. With 20 or 30, those conversations become rare.

The right number depends on the work. Teams doing similar, routine tasks with experienced employees can function with larger spans. Teams with new hires, complex work or high safety risk need more attention per person. A supervisor in a warehouse onboarding seasonal workers has very different demands than a manager leading a group of senior analysts.

Frontline supervisors often face the widest spans. In manufacturing, health care and logistics, one shift supervisor may oversee dozens of workers while also covering production or patient care. Those settings tend to have the highest turnover, which we explore in our manufacturing workforce report.

What coaching looks like

Coaching is different from training. Training teaches a skill in a classroom or online course. Coaching helps managers apply it on the job through regular conversations with a mentor, peer group or professional coach. It covers real situations, such as handling a conflict between employees, giving difficult feedback or supporting someone who is struggling.

Coaching does not have to be expensive. Some employers pair new managers with experienced ones. Others create small peer groups that meet monthly to discuss challenges. HR business partners can serve as coaches for frontline supervisors. The key is consistency over time rather than a single workshop.

Good coaching also models the behavior managers are expected to show their own teams. A manager who is regularly asked thoughtful questions about priorities and obstacles learns to ask the same questions of the people they lead.

Practical steps for employers

Start by measuring spans. Count direct reports for every manager and look for outliers. Compare those numbers with engagement scores, turnover and absenteeism by team. Patterns often emerge quickly.

Where spans are too wide, consider team leads or senior employees who can handle some day to day questions, scheduling and onboarding. This gives managers more time and creates development opportunities for future leaders, a path we explore in our report on internal mobility.

Invest in new managers early. Many people are promoted because they excelled as individual contributors, then receive little guidance on managing others. A structured first-year program with training, a coach and regular check-ins can prevent costly mistakes.

Give managers tools for regular conversations. Stay interviews, described in our guide to stay and exit interviews, are a simple way to learn what employees need. Short weekly check-ins focused on priorities and obstacles keep teams aligned without adding meetings.

Engaged managers produce engaged teams, and engaged teams tend to stay. Employers struggling with retention often look first at pay and benefits, which matter. But the daily experience of working for a capable, available manager shapes whether employees stay. Reasonable spans and real coaching are among the most direct ways to improve it.

The investment is modest compared with the cost of turnover. Our report on tenure and turnover costs explains why keeping experienced employees saves far more than replacing them.
