Supporting a return after mental-health leave
For the manager arranging it — the employee's side is in the guides.
4 minUpdated 4 August 2026
Returns fail for predictable reasons, and almost all of them are decided before the first morning back. This is the manager's side; the employee's version is in going back to work after time off.
Arrange it before day one
A meeting, and something in writing. Settle:
- Hours for each week of the phase, and the review date
- What they will and will not be doing — a reduced remit, not just reduced hours
- Who they go to if it is not working, and it should not be you if you are also the person appraising them
- What colleagues will be told, and by whom, agreed with them
- What happens if they need to step back again
That last one is the one everybody skips and the one that decides whether the return holds. Without an agreed route back to reduced hours, any sign of struggling feels to the employee like the whole thing collapsing, so they hide it until they cannot.
Phased means phased
Two or three short days in week one, building over four to six weeks. Sometimes months. In the UK, an agreed phased return is normally paid at the normal rate — check before you promise anything, and get the arrangement written down either way.
Return to a smaller version of the job, not the same job with fewer hours in it. A person doing a full remit in three days is not on a phased return; they are doing the same job badly and feeling worse about it.
The backlog is not theirs
Decide explicitly what has been written off or reassigned, and say so. In the absence of a decision, the backlog silently becomes their problem on day one, which is exactly the thing that made them ill.
Adjustments worth offering before being asked
- Later start, if mornings or medication make them impossible
- Fixed hours — no overtime, no on-call, a hard stop
- A quieter space, or fewer days in a loud open-plan office
- Fewer meetings, or agendas in advance so nothing is sprung
- Protected breaks that do not evaporate when it gets busy
- Time off for appointments without using annual leave
Where a condition has a substantial long-term effect, these are likely to be reasonable adjustments you are obliged to consider, not favours. Offering them unprompted saves the employee a conversation they are dreading.
Occupational health
Refer if you can. It converts "my manager thinks I need help" into a documented professional recommendation, which is much harder for the organisation to quietly drop.
You get a report about work capability and adjustments — not their diagnosis, not their notes, not what they said in the appointment. Tell them that beforehand, because most people assume otherwise and it changes what they say.
The week-three wobble
Expect it. The adrenaline of returning fades, the novelty goes, and the reality arrives. It is the most predictable point of collapse and it is very often read by everyone — including the employee — as proof the return was premature.
It usually is not. Reduce, do not abandon. Book a review for around week three before it happens, so adjusting is a scheduled event rather than a crisis.
If the job is the problem
Sometimes it is. If the workload, the manager, the shift pattern or the culture is what made them ill, adjustments treat a symptom.
That is worth naming honestly rather than managing around, because the alternative is a cycle of return and collapse that everybody can see and nobody says out loud. A different role inside the organisation is often the answer, and it is a far cheaper outcome than the one you get by not asking.
