When someone resigns and the reason traces back to their manager, it’s tempting to log it as ordinary turnover and move on. We’d treat it as something more useful: a sign that there might be a bigger issue internally.
You’ve probably heard that people leave managers, not companies. That line is too simple to explain every exit, but there is truth in it. Managers shape the daily experience of work through expectations, feedback, recognition, accountability, coaching, and trust.
Gallup found that managers account for 70% of the variance in team engagement, and only about 44% of managers worldwide say they’ve had any formal management training. Many of your managers are leading people with a skill no one ever taught them.
So when an exit points back to a manager, it’s usually telling you something, and there’s a lot you can do about it.
Read the Resignation as a Sign, Not Routine Turnover
In talking with our own EANE trainers Sandi Mauro and Kevin Joly, both describe the same story: a strong individual contributor gets promoted, then is asked to delegate, coach, set boundaries with former peers, give feedback, and clarify expectations, with no preparation for any of it. Someone can become an expert at the work quickly. Becoming good at leading people takes deliberate practice.
The signals usually arrive before the resignation letter:
- Mauro points to turnover patterns, employee satisfaction data, absenteeism, productivity, quality problems, and how people carry themselves when they walk into and out of a department.
- Joly adds employee complaints, poor performers who linger without correction, and managers who quietly skip the hardest parts of the job, especially accountability and development.
Clarity is one of the most revealing signals of all. In Gallup’s recent data, only about 46% of U.S. employees strongly agree they know what’s expected of them at work, down ten points from a high of 56% in early 2020. Without job clarity, your people start guessing, your managers start correcting after the fact, and frustration builds on both sides.
The strain gets worse when the managers themselves are running on empty. Gallup found that manager engagement fell from 30% to 27% globally in 2024, with the steepest drops among managers under 35 and women in management.
Plenty of your managers need support as much as their teams do.
The Manager Behaviors That Push Good People Out
Across our trainers’ experience and the broader research, we see the same patterns. People tend to leave when the relationship with their manager makes work feel unclear, unfair, stagnant, or exhausting.
- Unclear expectations. Mauro calls vague goals a “game of chance.” When the standard is never made concrete, employees decide for themselves what matters or do the safe minimum. Say a manager tells one person a report is “due soon” and never defines soon, the format, or what good looks like. The employee guesses, the manager is disappointed, and neither of them can point to what went wrong.
- Weak boundaries after a promotion. New managers often inherit former peers and friends. Joly stresses that a clean transition needs an explicit reset of expectations and boundaries. Mauro puts it plainly: the role changed, so the behavior has to change too.
- Delegation without follow-through. Many new managers feel guilty handing off work, or they delegate once and then vanish. Joly argues that consistent follow-up is what builds authority and respect.
- A one-size-fits-all communication style. Mauro and Joly both tie good leadership to self-awareness. Managers need to understand how they naturally give information, how different people prefer to receive it, and how to adjust the delivery without softening the message.
- Rescuing instead of coaching. Mauro warns that managers often jump in, solve the problem themselves, and accidentally train dependence. Employees get short-term help and lose long-term confidence and ownership.
- Managing tasks while ignoring development. Both trainers draw a hard line between assigning work and growing people. When a manager only watches output, the strongest performers start looking elsewhere for the coaching and the future they’re not getting.
Recognition belongs on this list too. Workhuman and Gallup tracked more than 3,400 employees from 2022 to 2024 and found that those who received high-quality recognition were 45% less likely to have left by the end of the study. Recognition is one of the daily ways your people decide whether their manager truly sees their work, even if it can’t make up for weak leadership.
The Hidden Cost of Turnover
Here’s why this is worth your time: Replacing an employee typically runs 50% to 200% of their annual salary once you add up recruiting, onboarding, lost productivity, and the months a new hire needs to get up to speed. For someone earning $60,000, that’s roughly $30,000 to $120,000 walking out the door.
That’s the visible cost of one exit. When the manager behind it stays untrained, the cost keeps compounding quietly, across the rest of the team’s performance, engagement, and the next person who decides to leave.
What HR and Organizational Leaders Should Do
When an employee quits because of a manager, the right response goes deeper than backfilling the seat. It’s a review of the leadership system.
EANE’s leadership training approach frames this in practical business terms: developing new managers, reducing inconsistency across departments, fixing productivity problems tied to unclear expectations, and addressing the retention issues that keep recurring.
A strong response usually includes these types of actions.
- Identify patterns, not anecdotes. Capture the stated reason for the exit, the team, the manager, tenure, and any recurring theme: feedback, favoritism, conflict, lack of growth. As Mauro emphasizes, one-off stories only become strategy once you track them.
- Review the manager’s team data over time. Look at turnover, absenteeism, complaints, engagement results, quality, missed deadlines, and performance spread across at least the past 6 to 12 months. Joly and Mauro both treat these operational signals as the fastest way to see whether the problem is bigger than one departure.
- Talk to the people still on the team. Conversations and stay interviews show whether the same tension is hitting everyone else.
- Diagnose the skill gap. “Needs leadership training” is too vague to act on. Mauro and Joly point to specific, assessable failure points: delegating to former peers, setting expectations, following up, coaching, giving feedback, handling conflict, and adapting communication style.
- Make the manager’s manager accountable for the fix. Joly is clear that senior leaders have to “manage how they manage.” That means supporting the leader, observing the behavior, and verifying improvement over time, rather than waiting for the next resignation to confirm the problem.
What to Coach Your Managers to Change Now
Your managers need a clear picture of what to do differently. Here’s a practical approach to walk your managers through.
- Define what good looks like (in plain language). Spell out output, quality, deadlines, decision rights, and behavior. Your people should know what success looks like this week, this month, and this quarter.
- Reset the relationship when moving from peer to manager. A short, honest conversation does the trick: the relationship still matters, the role changed, and accountability is now part of the job. That clarity is nicer than leading through awkwardness.
- Treat delegation as opportunity, not guilt. Joly recommends framing it as trust in someone’s capability. Mauro adds the bigger reason: a manager who keeps dragging old work into a new role loses the time for the work only they can do.
- Follow up consistently. Authority comes less from the title and more from actions. Ask when the work will be done, what support is needed, and when they’ll reconnect. Then reconnect.
- Adapt feedback to the person. Some people want directness and speed; others need context and trust first.
- Coach instead of rescuing. Let people think, answer, and own the outcome. As Mauro puts it, even when a manager knows the answer, they do more for the employee by making room for them to build confidence.
- Keep notes on patterns. Mauro describes a “secret notebook” on people, not as surveillance, but as a way to reflect. What worked in that conversation? What missed? What motivates, shuts down, or re-engages this person? That kind of observation makes the next conversation better.
Kevin Joly says people form their opinion from the larger sample of a manager’s behavior over time, not just one instance. Fairness, care for the business, and care for the person have to show up again and again before they add up to trust.
A Training Response That Actually Fits the Problem
A manager-driven resignation should lead to a training or development conversation. EANE’s leadership and manager training lines up with the real causes behind this kind of exit:
- Foundational Leadership 101 is built for first-time leaders making the shift from doing the work to leading others.
- Foundational Leadership 102 focuses on accountability, conflict, and leading change as responsibilities grow.
- Principles of Leadership for Supervisors & Managers Series is designed to turn a reactive manager into a more intentional, strategic, and effective one.
Mauro offers the best reminder for any organization on the fence about investing in its managers: “What if we don’t and they stay?” One exit is a visible cost. An untrained manager who stays is a cost that keeps adding up across performance, engagement, and retention. That’s exactly why targeted manager training belongs in your response.
