The line manager’s mental health toolkit: what to say, what to do, where the line is
Managers are told to have the conversation and almost never told what to say next. This guide gives them the words, the shape of the conversation and, just as importantly, the point at which their job stops and somebody else’s begins.
Only 29% of organisations train their line managers in mental health. And 35% of workers say they would not feel comfortable discussing high or extreme stress with a manager. Those are the same fact seen from both ends, which is the uncomfortable part. CIPD, Health and Wellbeing at Work 2025 · Mental Health UK, Burnout Report 2026

The rest of the guide covers the openers that work, the shape of a good conversation, the five phrases to avoid, where a manager’s role ends and what to do in the fortnight after. One-off, you won’t need to do this again on this device.
The instruction without the training
Almost every organisation now tells its managers that supporting employee mental health is part of the job. Rather fewer have told them how, and the workforce has noticed.
The job got bigger, the training did not
Manager training has historically covered process: appraisals, absence forms, performance frameworks. The human part of the job was assumed to be instinct. Only 29% of organisations train their line managers in mental health (CIPD, Health and Wellbeing at Work 2025), which means most are improvising something they have been formally told is their responsibility. Anxiety about getting it wrong is the predictable result, and avoidance is the predictable behaviour.
Employees are reading it accurately
35% of workers say they would not feel comfortable discussing high or extreme levels of stress with a manager (Mental Health UK, Burnout Report 2026). Set against the training figure, that is not a perception problem to be corrected with better communication. It is an accurate assessment of a real gap, and it matters because the manager is usually the first person anybody tells. If a third of the workforce has quietly concluded the conversation would not help, most of them will not start it.
The stakes are higher than most managers realise. 69% of people say their manager affects their mental health, the same proportion as say their partner does, and more than say their doctor (51%) or therapist (41%). Workforce Institute at UKG, survey of 3,400 people across 10 countries, 2023
It is saying nothing, because the manager is not confident enough to start and is frightened of making it worse. Almost every manager who has avoided the conversation says the same thing afterwards: they did not know what they were supposed to do with the answer. That is a solvable problem, and it is what the rest of this guide is about.
What to say, and what to do next
Six practical parts, in the order you will need them. None of this requires clinical knowledge, and none of it asks a manager to diagnose anything.
Open on the observation, not the diagnosis
“Are you OK?” invites “fine” and both of you get to move on. The opener that works names something specific you have actually noticed, without interpreting it. It is harder to deflect and it signals that you were paying attention rather than working through a checklist.
- Use the shape: “I’ve noticed [specific thing] over the last [period]. How are you doing?”
- Describe behaviour, never character. “You’ve been quieter in stand-ups” lands. “You’ve seemed down” is a verdict.
Get the setting right before you get the words right
Where and when you ask does more work than the phrasing. A conversation started in an open-plan office two minutes before a meeting will fail regardless of how well it is worded, because the person has nowhere to put the answer. Privacy, unhurried time and no screen between you cover most of it.
- Give it more time than you think it needs, and do not schedule anything hard against the end of it.
- A walk is often easier than a meeting room. Side by side removes the interview dynamic.
Listen for longer than is comfortable
The instinct is to fill the silence, and the instinct is wrong. Most managers move to solutions within about 20 seconds, which reads as wanting the conversation over. The most useful thing you can do is say very little and let a pause run. What comes after the pause is usually the real thing.
- Reflect back what you heard before responding to it. “So the workload is manageable, it’s the uncertainty that’s hard.”
- Resist the urge to fix. Most of what closes these conversations is said with good intentions.
None of these are unkind. They are all things a decent manager says under pressure, and each one quietly ends the conversation.
1. “At least it’s not…” Ranks their problem against a worse one. They stop talking rather than argue the ranking.
2. “Have you tried…?” Moves to solutions before you have understood the problem, and implies they have not thought of the obvious.
3. “I know exactly how you feel.” Turns their disclosure into your story. “That sounds really hard” does the same work without the claim.
4. “Everyone’s under pressure at the moment.” Meant as reassurance, heard as “this is normal, stop raising it”.
5. “Let me know if you need anything.” Sounds generous and hands the entire job of asking back to the person least able to do it. Name the specific thing you will change instead.
Know where the line is
This is the part that most reduces manager anxiety, and it is the part nobody explains. A manager is not a counsellor, is not expected to diagnose anything and should not try. The role is to notice, to listen, to adjust what is within your gift at work and to signpost to the people who are qualified. Being clear about that boundary is what makes the conversation safe to start.
- Know your organisation’s routes before you need them: occupational health, the EAP, HR and the person’s GP.
- Say the boundary out loud. “I’m not the expert here, but I can change things at work and I can help you find the right support.”
Change something at work, however small
This is the half of the job that is genuinely yours, and it is the half most often skipped. A supportive conversation that changes nothing about the work is experienced as sympathy, and sympathy wears out quickly. Deadlines, workload, meeting load, hours, who someone is paired with: these are all within a manager’s gift and all of them are more useful than a leaflet.
- Agree one concrete change before the conversation ends, and write it down in front of them.
- Ask what would help before proposing what you think will. People usually know, and are rarely asked.
Come back to it: the fortnight after
One conversation is a moment. Two conversations is support. The follow-up matters more than the opener because it proves the first one was not a box being ticked, and it is the single easiest thing to let slip once the diary fills back up. The next two weeks are where most of these conversations are quietly undone, so treat them as part of the job rather than the aftermath of it.
- Before you leave the room: book the follow-up, inside two weeks, in the diary. A vague “my door’s open” puts the whole burden back on them.
- Same day: agree what, if anything, gets shared and with whom. Let them decide, and then hold to it exactly.
- Week one: make the change you agreed actually happen. An adjustment that never lands tells them the conversation was theatre, and they will not start a second one.
- Week two: hold the follow-up even if things look fine, and keep it short. Ask whether the change helped, not how they are coping. It is a better question and it is easier to answer honestly.
- Throughout: treat them normally. Being quietly dropped from the interesting work is the most common thing people regret disclosing, and it is rarely done deliberately.
Among employers who train their line managers in mental health, 73% say those managers are confident holding sensitive conversations and signposting to support. Among employers who do not train them, 57% (CIPD, Health and Wellbeing at Work 2025). This is not an innate quality some managers have. It is a skill, it responds to practice, and practising it on a real person for the first time is the expensive way to learn.
