The short answer: a good return starts before the person comes back. Keep in light, agreed contact while they are off. Have a relaxed, private conversation before or on their first day. Agree a plan together, which often includes a phased return and a few practical adjustments. Then keep checking in over the following weeks, because the first few days are rarely where things go wrong. It is the weeks after, when everyone assumes things are back to normal.
Returning after time off for mental health can feel harder than going off in the first place. People worry about what colleagues think, whether they are still trusted, and whether it will happen again. How their manager handles those first conversations can decide whether the return sticks.
This article is part of our practical guide to workplace mental health training for UK employers.
What should happen while someone is off?
Agree how you will keep in touch. Early in the absence, ask the person how and how often they would like to hear from you. For some it is a short weekly text. For others it is a call every couple of weeks. Too much contact can feel like pressure. None at all can feel like being forgotten.
Keep contact human, not procedural. “Thinking of you, no need to reply” does more than “Please confirm your expected return date.” There will be times you need to discuss the formal side, but it should not be the only thing they hear from you.
Understand the fit note. In the UK, someone needs a fit note once they have been off for more than 7 days, including weekends. A doctor or other healthcare professional can say someone is “not fit for work” or “may be fit for work” with some support, such as a phased return, altered hours, amended duties or changes to the workplace. If you cannot offer the support suggested, the note is treated as “not fit for work”.
Know what outside help exists. The Access to Work Mental Health Support Service, funded by the Department for Work and Pensions, offers free support to employees with mental health difficulties for up to nine months. It can help someone stay in work or get back to it, and you can point people towards it.
Tell the team only what the person agrees to. Ask them what, if anything, they would like colleagues to know, and how they would like their return to be handled.
How do you have the return to work conversation?
If you can, have this conversation before their first day back, or first thing on the day. Make it private, unhurried and clearly separate from any formal absence process your organisation has.
Start by welcoming them back. Simple and warm.
“It’s really good to have you back. How are you feeling about today?”
Let them set the pace on detail. You do not need to know their diagnosis or what happened. You need to know what will help.
“You don’t have to go into anything you don’t want to. What I’d like to understand is what would make coming back easier.”
Ask about triggers and early signs. This is one of the most useful questions and one of the least asked.
“Is there anything about work that made things harder before? And is there anything I might notice if things start to get difficult again, so I can check in early?”
Agree a plan together. Hours, workload, any adjustments, and how you will review it. Write it down and share it with them so there are no surprises.
Agree how you’ll check in. A short weekly catch up for the first month or two is a good starting point.
What not to say
- “Are you sure you’re ready?” It sounds caring but plants doubt.
- “We’ve really missed you, it’s been chaos.” They will hear guilt.
- “So what was actually wrong?” They may choose to tell you. It is not yours to ask.
- “Just take it easy” with no actual change to their workload. Words need to be matched by action.

What adjustments can help?
Adjustments do not have to be expensive or complicated. Many cost nothing. Common ones include:
| Adjustment | What it looks like |
|---|---|
| Phased return | Shorter days or fewer days a week at first, building up over a few weeks |
| Changed hours | Later starts if mornings are hard, or avoiding rush hour travel |
| Lighter workload | Fewer deadlines or targets for a set period, with a date to review |
| Changed duties | Temporarily stepping back from the most pressured parts of the role |
| Time for appointments | Protected time for therapy, GP or other appointments |
| Working location | Some home working, or a quieter space in the workplace |
| Regular check ins | A short, predictable catch up rather than waiting for problems |
If someone’s condition meets the Equality Act 2010 definition of disability, you have a legal duty to make reasonable adjustments. Whether it does depends on the individual, so it is better to treat reasonable adjustments as good practice for everyone rather than trying to decide who qualifies.

Why the first few months matter most
The first day usually goes fine. The risk comes later. After a couple of weeks, everyone assumes things are back to normal. The phased return ends, the workload creeps back up, and the check ins quietly stop.
To avoid that:
- Put review dates in the diary and keep them, even when things seem to be going well.
- Increase workload deliberately, not by default.
- Watch for the early signs you agreed, and check in as soon as you notice them.
- Keep the door open. Remind them, now and then, that they can come to you if things start to slip.
Managers often tell me these conversations are the part of the job they feel least prepared for. That is exactly what our Manager Mental Health Awareness Training covers, alongside the absence, performance and legal considerations that sit around them.
Frequently asked questions
How long should a phased return last?
There is no fixed rule. Two to six weeks is common, but it should be agreed with the person and reviewed rather than fixed in advance. Follow any advice on their fit note or from occupational health.
Can I ask what their mental health condition is?
You can ask what would help, but they do not have to tell you their diagnosis. Focus on what they need at work, not on labels.
What if they go off again?
It happens, and it does not mean the return failed. Keep the same supportive approach, review what did and did not help, and look at whether anything at work needs to change.
Do I need occupational health?
Not always. For longer or repeated absences, or where you are unsure what adjustments are needed, an occupational health referral can give useful independent advice.
The bottom line
A good return to work is less about the first day and more about the first three months. Plan it together, write it down, keep checking in, and treat adjustments as normal rather than special. Done well, it is one of the clearest signs to everyone in the team that it is safe to ask for help.
If your managers would benefit from support with these conversations, or you want to check whether your absence and return to work processes support people well, our Workplace Mental Health Systems and Support Review is a good place to start. Or book a free call to talk it through.
