Why Employees Leave Managers, Not Companies

The people you work with can make or break how you feel about your job, and the relationship with a manager tends to carry more of that weight than almost anything else. Ask someone how work is going, and the answer usually circles back to that relationship in some form, whether they feel listened to or simply left to get on with it. When that relationship isn’t working, it can really impact how people feel about their work.

Even someone who likes their job can still resign because of it, and that reason rarely gets reported. Exit interviews tend to cite pay, or opportunity, or timing, because those are easier things to say out loud. What’s harder to say, and just as often true, is that the job was never really the problem. It was what it felt like to work for someone like that, day after day.

Bad management doesn’t always result in direct conflict. Sometimes it’s more subtle than that, a manager who’s simply never quite present, whose feedback arrives too late to matter, or whose team learns not to bring things to them because nothing ever seems to change.

How much of retention really comes down to the manager?

Most retention strategies focus on pay, perks, and career progression, and rarely look closely enough at the manager relationship itself, despite it being one of the clearest predictors of whether someone stays. Research from the Chartered Management Institute (CMI) and YouGov, based on a survey of over 4,500 UK workers and managers, found that one in three people have left a job because of bad management and a negative workplace culture, and among those who rate their manager as ineffective, half say they’re planning to leave their organisation within the next year, compared with just 21% of those with an effective manager.

The CMI research found that employees under an ineffective manager report feeling markedly less valued and less motivated to do good work than those under an effective one, which explains  why so many of them are already planning their exit.

This often has less to do with who someone is as a manager, and more to do with how they got there. The CMI also found that 82% of people entering management roles in the UK have had no formal management or leadership training at all, often described as “accidental managers,” promoted for being good at their previous job rather than equipped for the very different job of leading people, a gap that leaves a significant proportion of the workforce being managed by someone who was never actually taught how.

What does poor management actually look like day to day?

Poor management tends to sit at one of two extremes, a manager who micromanages until autonomy disappears, or one so hands-off that their team is left without any real direction. LiveCareer’s 2026 Bad Bosses Report, surveying 1,000 professionals across the UK and Europe, found that 76% of employees now consider poor management a common, or even unavoidable, feature of modern workplaces. The impact tends to build gradually rather than all at once. Teams stop sharing ideas or concerns once they no longer feel safe doing so, communication becomes strained, and people who once collaborated start to disengage or pull away from each other entirely, until the working relationships that used to hold a team together have simply worn thin.

Much of this comes down to a lack of core people management competencies rather than any deliberate intent to cause harm. Very few managers set out to be difficult to work for. More often, they’re missing fundamental skills like communication, coaching, and emotional regulation, skills that are rarely built into how someone is trained, or in most cases, never trained at all before they’re handed a team to lead.

Is the manager the cause, or just where it shows?

Blame tends to land squarely on the manager in these situations, though that’s rarely the whole picture. A struggling manager is often a symptom of something happening further up an organisation, rather than a standalone failing, and CMI’s research points to exactly this kind of cycle in practice. Among managers who wanted to raise concerns about their own struggles but chose not to, most cited a fear they wouldn’t get enough support from those above them, which mirrors almost exactly why employees stay quiet about a manager who isn’t working for them. Nobody involved feels able to say the thing that might actually fix it, and that mutual silence is often what allows poor management to settle in rather than get addressed early.

This matters because it changes where the fix needs to happen. Holding individual managers accountable without addressing how they got there, untrained, unsupported, and often unaware of what good management actually looks like, treats the symptom while leaving the cause untouched. The manager is usually where a deeper problem becomes visible to employees. It’s rarely where that problem actually started.

What does this cost a business in practice?

Turnover driven by poor management isn’t only a people problem, it carries a real financial cost too, one that’s often bigger than organisations account for when weighing up whether to invest in manager development. It’s not an easy figure to pin down precisely, since so many variables feed into the calculation, but research from Culture Amp puts the cost of replacing an employee at 30% to 200% of their salary, once recruitment, productivity, and the impact on a team are all factored in, which on the UK’s average salary translates to somewhere between £11,000 and £75,000 per departure, depending on seniority and role complexity.

The disruption reaches well beyond the person who leaves. Whoever remains tends to absorb the extra workload, while those still working under the same manager may begin to question whether they want to stay too. One resignation can create a wider sense of uncertainty, with others considering their own way out. There’s a less visible cost too: the knowledge and experience that leaves with them and has to be rebuilt with whoever comes next

What can employers actually do about it?

Treating manager quality as seriously as any other investment in the workforce doesn’t require a different way of running a business. It just requires not assuming good management will happen on its own once someone is handed the title.

Invest in manager training.

Given that the vast majority of UK managers step into the role with no formal training at all, this is one of the more direct, addressable gaps behind almost everything covered so far, since so much of what looks like a character failing is really a skills gap nobody ever closed.

Build regular feedback loops.

A once-a-year conversation can’t catch a relationship that’s quietly deteriorating in the months in between, and the same lack of communication that lets poor management go unaddressed tends to be broken far more easily by small, frequent check-ins than by a single formal review most people dread anyway.

Support managers properly.

A manager promoted without training and left to work it out alone was never set up to succeed. They need the same kind of support further up the chain that they’re expected to give their own team, someone checking in on how they’re actually doing, and a genuine space to talk through what isn’t working, rather than being left to manage entirely on their own.

Make recognition consistent.

Much of what separates a manager that people want to stay with from one they eventually leave comes down to small, repeated behaviours rather than a single grand gesture, noticing effort and naming it clearly, done regularly enough that it becomes part of how a team works rather than something that happens once and is quickly forgotten.

The challenge is making those moments part of everyday working life. Simple ways to recognise contributions, whether through a quick message from a manager, peer-to-peer appreciation or a more structured approach, can make recognition feel less dependent on individual managers remembering to do it. When people regularly see that their work is noticed and valued, those small moments can have a much bigger impact on how connected they feel to their workplace.

The manager isn’t the whole story

“People leave managers, not companies” is true enough to be useful, but it isn’t the whole story. The manager is usually where a deeper problem becomes visible, not necessarily where it started, and treating manager quality as an individual failing rather than an organisational responsibility means the same pattern keeps repeating with whoever comes next. Investing in the people who lead teams, properly and consistently, tends to do more for retention than almost anything else on a benefits list, because it’s rarely the job someone leaves. It’s the person they were left to navigate it with.
