The Most Important Infrastructure in Your Business Isn’t IT. It’s Your Line Managers

A practical guide for UK and Irish HR professionals

Rounds of layoffs are all over our social media feeds daily, the words of “we‘re exploring the capabilities of AI” are now treated more with dismay and worry by the employee base when a CEO or Site Lead announces it at a company all hands. HR will generally get a finger on the pulse when the company annual employee survey comes out or if they are operating best practice during a pulse survey to understand the feelings on the ground. For annual reviews HR will ask for feedback on an employee’s manager, whether they trust leadership, whether they’d recommend the company to a friend. Rarely does anyone ask the manager the same question, and that’s a problem, because the data is now unambiguous about what happens when a manager’s own motivation quietly drains away.

Why this matters more than it used to

Gallup’s global engagement research puts a hard number on something most HR professionals have long suspected that roughly 70% of the change in a team’s engagement is attributable to the manager. When managers are disengaged, their teams are too, and the effect is strong enough to show up in country-level comparisons, not just individual team data. The UK sits near the bottom of the European table for this: only around 1 in 10 UK workers report feeling engaged, and manager engagement specifically has been falling, with the sharpest drops among younger and female managers.

This isn’t just a UK story. The “squeeze” on middle managers has become one of the most consistent findings in workplace research over the past two years. Managers are now reporting higher daily stress than the people who report to them, caught between senior leadership demands they had no hand in shaping and direct reports who need support, clarity and protection from constant change. A number of large 2025 studies arrive on similar figures, around 45% of middle managers report burnout, a higher rate than either the employees below them or the executives above, and average spans of responsibility have grown sharply as organisations have flattened their structures, leaving each manager with more relationships to sustain than is realistically possible to do well.

CIPD’s Good Work Index and its Ireland-specific research tells a similar story. Line managers are increasingly the first (and sometimes only) point of contact for wellbeing conversations, yet many say they feel under-equipped to have them. CIPD’s own recommendation to employers is important: treat line manager time and capability as a material constraint, not an infinite resource, and build job design around that reality rather than assuming managers will simply absorb whatever is added to their plate.

Why it’s easy to miss

A disengaged manager rarely looks like a disengaged employee. There’s no dramatic drop in punctuality, no obvious sulking. What you tend to see instead is:

  • Delegation that’s actually abandonment — decisions get pushed down or sat on, not because the manager trusts the team, but because they’ve stopped wanting to be the one who decides.
  • One-to-ones that become status updates — no coaching, no development conversation, just a diary slot both parties are going through the motions.
  • Team engagement scores dipping — while the manager’s own scores (if you’re even measuring them) look fine, focussing on team engagement surveys which are rarely designed or implemented can offer strong indicators of discernment.
  • A manager who used to escalate problems and advocate for their team going quiet — not because things have improved, but because they’ve concluded raising issues doesn’t change anything.

As the manager is still hitting deadlines and still “performing” on paper, this often gets read as a personality issue, someone becoming a bit flat, has “checked out” rather than what it usually is: a structural symptom of overload, role ambiguity, or a manager who has stopped believing their input matters.

Two things worth trying

1.Give them an upward one-to-one, not just a downward one. 

Most managers spend their week asking their team how things are going and almost never get asked the same in return by anyone above them. If they have their own manager they are usually only meeting once a quarter with the vast majority of times focussed on team metrics. I would suggest a regular, protected conversation, not a performance review or a project update where a manager’s own line manager or an HR partner simply asks “how’s it actually going for you, and what’s getting in the way” opens a discussion of two things at once. It surfaces overload before it becomes burnout, and it re-establishes the sense that someone senior is genuinely invested in them, not just in what they deliver. This lines up with what self-determination theory (Deci and Ryan’s long-standing model of workplace motivation) identifies as the core drivers of sustained motivation: autonomy, competence, and relatedness. When a manager feels unseen by their own organisation, that third driver, relatedness is usually the one missing.

2.Give them back one real decision. 

Disengagement often tracks closely with managers who have been handed accountability without authority, expected to deliver outcomes using processes, headcount and priorities they didn’t set and can’t change. You don’t need a full restructure to address this. Identify one area a process, a resourcing decision, how the team runs its own meetings and allow the manager genuinely gets to decide, and then hold to that. Small, real autonomy tends to do more for motivation than a larger amount of symbolic authority that evaporates the moment it’s tested.

The bigger point for HR

It’s tempting to treat manager motivation as a “nice to have” that competes for attention with employee engagement. The research suggests the opposite: manager engagement is the infrastructure for everything else HR is trying to build. A well-designed engagement survey, a strong onboarding programme, a thoughtful reward strategy, all of it gets filtered through a manager before it reaches the team. If that manager is running on empty, the filter distorts everything passing through it.

The organisations getting this right aren’t necessarily spending more on manager development, or fancy two-day offsites. They’re asking a different question first: not “how do we get managers to drive more engagement,” but “do our managers currently have the capacity, authority and support to do the job we’ve designed for them?” That’s a harder question to answer honestly but it’s the one that actually moves the number.
