It is the most repeated line in HR. It is also half right, often misquoted and especially important in Nigerian workplaces where staff rarely say what they really think. Here is what the research shows.
Last updated: 28 October 2026
The resignation letter says “a better opportunity.” The exit form says the same. Then, a few weeks later, two more people from the same team hand in their notice, and someone in HR quietly asks who their manager was.
Most experienced recruiters have seen this pattern, and the slogan that explains it, “people leave managers, not companies,” is everywhere. This guide tests that slogan against the evidence, looks at what makes it especially relevant in Nigeria, and sets out what employers and recruiters can do. It is written for business owners, HR teams and recruiters.
A Few Notes Before We Start
The slogan is catchy but loose. The best-known statistic behind it is often misquoted, and we correct it below. Our Nigerian evidence comes mainly from small qualitative studies and surveys in specific sectors, such as banking, manufacturing, telecoms and healthcare, and we found no Nigerian study that measures what share of resignations are caused by managers. Much of the strongest data is American or British. We also use some figures that reach us through secondary summaries, and we flag them.
Where the Slogan Comes From, and What It Actually Says
The famous statistic comes from a 2015 Gallup survey of 7,272 US adults. As Gallup’s own summary puts it, one in two US adults said they had left a job to get away from their manager at some point in their career. Fortune’s report at the time described the survey the same way. That is a career-long measure. It does not say that half of all resignations are caused by managers.
Other evidence fits a more careful version of the claim:
- Gallup attributes at least 70 percent of the variance in team engagement to the manager.
- In a Gallup survey of 717 US workers who had left jobs, 21 percent said more positive interactions with their manager could have kept them, and more than 40 percent said their manager or employer could have prevented the exit.
- The Chartered Management Institute’s UK research found that one in three people had left a job because of negative culture or poor management.
- MIT Sloan Management Review found that a toxic corporate culture was the strongest predictor of attrition among large US employers in 2021, ahead of pay.
In Nigeria, the Intelpoint and AltSchool Africa survey of more than 2,600 workers ranked bad leadership as the third most common reason people leave, behind a better offer elsewhere and lack of career advancement.
Our verdict: the manager is one of the biggest causes of resignations, but not the only one. Pay, growth and the economy matter too. The slogan is still useful because managers influence many of those other factors. They shape workload, recognition, development and whether a raise is requested. That last point is our reading of the evidence, not a measured result.
Why Managers Matter So Much
To an employee, the manager is the company. They set priorities, give or withhold feedback, approve leave and decide who gets the interesting work. Yet managers are often chosen badly. A TD Magazine summary of Gallup’s research says only about one in 10 people is naturally gifted at managing others, and Gallup’s data suggests many managers got the role because they were good in a previous non-managerial job. In Nigerian startups, Techpoint Africa reports that fast growth pushes people into management before anyone checks whether they are ready.
The result shows up in the engagement numbers. A summary of Gallup’s 2026 report, published by Silicon Canals, says global engagement was 20 percent and manager engagement fell to 22 percent. That is a secondary source, so confirm the figures with Gallup before quoting them. Disengaged managers are rarely good at engaging anyone else.
Why It Matters Even More in Nigeria
High power distance means people stay silent, then leave
Nigeria is often described as a high power distance culture, where deference to authority is expected. A study in Employee Relations by Emeka Oruh and Chianu Dibia, based on interviews with 24 managerial and non-managerial workers in banking and manufacturing, found that this culture promotes a servant-master relationship that makes it hard for employees to challenge employers about work overload and unsupportive environments. The authors note that the small sample limits generalisation. A separate study of mobile telecommunications multinationals in Nigeria, by Emelifeonwu and Valk, found fear of victimisation and employee silence, shaped by national culture and a tight labour market, and found that culturally adapted employee voice mechanisms improved voice and performance.
What this means in practice: staff may not tell a manager that something is wrong. They may not tell HR either. They simply look for another job, and when they find one, the resignation appears to come from nowhere. It also suggests that exit interviews can understate problems with managers, because people who fear consequences give polite answers. That is our inference from the studies, not something they measured directly.
Bullying and abusive supervision are documented
Academic studies of Nigerian workplaces describe bullying as a real problem, though they are small and sector-specific. University of Lagos researchers Owoyemi and Akintayo interviewed 30 employees from public and private organisations to explore bullying in Nigerian work environments, and Adewumi and Danesi’s 2020 study concluded that bullying was widespread in the organisations studied and affected workers negatively. A study of 365 healthcare employees in Benin City, available through the University of Benin repository, found that bullying lowered morale and contributed to turnover intentions, with verbal abuse, unfair criticism, excessive workload and exclusion among the most common forms. Many respondents felt it was inadequately addressed despite existing policies.
These studies do not tell us how common bullying is across Nigeria. They do show that employees describe it, and that it is linked to wanting to leave.
Economic pressure sharpens the choice
With inflation at 15.43 percent in July 2026, a better offer is more tempting than before. That is when the relationship with the manager tips the balance. A supported employee may stay for a smaller raise. An unsupported one will not. This is again our interpretation, but it fits the Intelpoint ranking, where a better offer comes first and bad leadership third.
What Bad Management Looks Like
The behaviours that push people out are usually ordinary:
- No clear priorities. In the 2015 Gallup research, only 12 percent of workers strongly agreed that their manager helped set work priorities, according to Fortune.
- Little or no feedback. People find out about problems at the annual review or at resignation.
- Favouritism. The CMI found that 46 percent of managers believed promotions often depended on relationships and profile, not ability.
- Overload and verbal abuse. The Benin City study lists these as common forms of bullying.
- Silence about conflict. Managers who ignore difficult team members frustrate their strongest performers.
What Good Managers Do Differently
The fixes are not mysterious. Gallup’s advice, summarised by Government Executive, is for managers to communicate reliably, hold regular performance conversations beyond the annual review, help set priorities and focus on strengths. Regular one-to-ones matter in particular. SHRM reports, citing Quantum Workplace and Gallup, that employees who meet regularly with their managers one-on-one are three times more likely to be engaged, and that Adobe’s turnover fell by 30 percent after it replaced annual reviews with more frequent check-ins. Those are secondary and company-specific figures, so treat them as encouraging, not guaranteed.
What Nigerian Employers Should Do
- Look at exits by manager. Count resignations by team and manager over the past two years. One manager with repeated exits is a signal that pay and market conditions cannot explain.
- Create safe ways to speak up. Given the silence the Nigerian studies describe, use anonymous upward feedback, skip-level conversations and stay interviews with your best people, and then act visibly on what you hear.
- Choose managers deliberately. Do not promote people simply for being strong individual contributors. Offer a technical career track for those who do not want to manage.
- Train before promotion. Teach expectations, feedback, delegation and conflict handling at the start, as we argue in Managers Should Be Trained Before Managing People.
- Write and enforce a policy on bullying and harassment. The Benin City researchers recommend stronger policies, management intervention and awareness programmes. Give people a reporting channel that does not run through their own manager, and investigate complaints.
- Make one-to-ones normal. A short weekly or fortnightly conversation about priorities, workload and growth costs little.
- Give managers the conditions to succeed. Fair pay, realistic workloads and sane hours matter, as we explain in If You Can’t Pay Fair Salaries, Don’t Hire and Long Working Hours Don’t Mean Higher Productivity.
- Hold managers accountable for people results. Include retention, team feedback and development in their reviews, not only output.
- Do not protect high performers who mistreat people. Strong output from a bullying manager hides a cost that arrives later as exits.

What Recruiters Can Do
Recruiters often sit between a client and a candidate who is about to ask the one question that matters: who will I report to?
- Ask about the manager at intake. Find out who the role reports to, how long they have been in post and what turnover that team has had.
- Let candidates meet their future manager. Candidates judge the role by the person, and the best ones will ask.
- Be honest about the team. Misleading candidates about the manager produces early exits, as we describe in Why Your Recruitment Process Is Chasing Away Top Talent.
- Track retention by client and manager. If placements under one manager keep leaving, tell the client.
- Advise on employer brand. A company known for good managers attracts better people. See What Is Employer Branding, and Why Should a Nigerian SME Care?
Frequently Asked Questions
Is it true that people quit managers, not companies? Partly. Managers are one of the biggest influences on engagement and retention, but pay, growth and the economy matter too. The widely quoted “50 percent” figure measures career-long behaviour among US adults, not the share of resignations.
Is pay more important than the manager? In the Nigerian survey we found, a better offer ranked first and bad leadership third. But a good manager can reduce the pull of a better offer, and a bad one can make it irresistible.
How can we tell if a manager is the problem? Look at turnover, absence and engagement by team, and compare managers. Repeated exits from one team are a warning sign, and anonymous feedback helps confirm it.
What if the manager is the owner of a small business? Ask a trusted adviser or a mentor to give honest feedback, set up a channel for staff to raise concerns and consider management training for yourself. Owners often cause the same problems as managers, and they are the hardest to hear about.
Can bad managers improve? Many can with training, feedback and support, especially those who were promoted without preparation. Where there is bullying or abuse, act on it, not just coach it.
How do we hear the truth in a workplace where people fear speaking up? Use anonymous surveys, skip-level meetings and an independent channel such as an HR contact or an external provider, and show that raising a concern does not lead to punishment.
The Bottom Line
The slogan is not a law of nature, but it points at something real: managers shape whether people feel supported, respected and able to grow, and in Nigerian workplaces where deference discourages honesty, the damage often stays hidden until someone leaves. Measure exits by manager, build safe ways for staff to speak, train people before they lead and act on mistreatment. When you are ready to hire, you can post a job on MyJobAlly and tell candidates honestly what working in your team is like.

Several sources are press summaries, small qualitative studies and secondary reports, and may use different methods. The Gallup 2015 figure measures career-long behaviour among US adults, and the CMI figures cover UK workers. The Nigerian studies are small and sector-specific. We found no Nigerian study measuring what share of resignations are caused by managers.
