Returning to work after rehab in London works best as an agreed transition with your treatment team and employer. The plan should connect your current health and abilities with the demands of the job, while protecting time for continuing care. Completing a residential program does not automatically establish readiness for every duty, shift, or level of workload.
There is no single number of days after discharge when everyone should return. Ask for advice based on your condition, treatment, medication, responsibilities, and working environment. Then agree the practical arrangements with the people responsible for implementing them.
Describe the job in enough detail for useful advice
A clinician can give more relevant advice if they understand what your work involves. Describe hours, shifts, travel, deadlines, responsibility for other people, decision-making, and any safety-sensitive tasks. “Office work” may conceal a demanding client-facing role or frequent international travel.
Explain which parts currently feel manageable and which do not. You might be able to complete focused tasks at home but find crowded commuting and back-to-back meetings difficult. Someone else may cope with the journey but struggle with concentration late in a shift.
Ask whether medication or symptoms require specific restrictions or review. Do not assume that feeling better in a structured treatment setting means every aspect of the previous working pattern is now suitable.
Use clinical advice and occupational health for different purposes
Your treating clinician understands your health and treatment. Occupational health focuses on how your health and job affect each other. Acas explains that an occupational health assessment can add work-specific information to a fit note or medical report.
Ask what questions the employer is putting to occupational health. A focused referral might ask about phased hours, particular duties, follow-up appointments, or the timing of a review. It should be clear what decision the assessment is intended to support.
If advice from different professionals appears inconsistent, ask for clarification. They may be answering different questions or working from different information. Avoid becoming the sole messenger between people whose recommendations need to be reconciled.
Our guide for working professionals discusses treatment, confidentiality, and professional responsibilities more broadly. The return plan should translate those considerations into concrete arrangements for the next stage.
Understand what a fit note does
The government’s fit note guidance explains that the note gives advice about how health affects the ability to work. It can indicate that someone may be fit for work with changes, rather than simply dividing everyone into fully recovered or unable to work.
Discuss the functional effects that matter: stamina, concentration, sleep, emotional demands, or tolerance of particular activities. A helpful conversation goes beyond the name of a diagnosis and considers what might make work possible.
Check the dates and advice on the note, and discuss them with your employer. A fit note does not itself arrange a revised shift, remove a deadline, or book a follow-up meeting. Those actions need agreement and implementation.
Make a phased return specific
Acas’s phased-return guidance, updated October 1, 2026, describes gradual return through reduced hours, different work, or a lighter workload. Duration should reflect individual circumstances and be agreed and reviewed with the employer.
Write down the initial hours, duties, location, and review date. “Take it easy for a while” leaves too much open to interpretation. A reduced working day is unlikely to help if the same workload is compressed into fewer hours.
Agree which tasks remain with colleagues during the initial period and who handles requests outside the plan. If clients or other teams are involved, the manager may need to communicate the operational arrangements without disclosing private medical information.
Decide how progression will be reviewed. Increasing hours, workload, and travel simultaneously may make it difficult to identify what is causing a problem. Ask the relevant professionals how to evaluate the next step and what would justify slowing or revising the plan.
Clarify pay before the arrangement starts
A phased return does not automatically mean full pay. Acas explains that pay depends on the arrangement, employer policy, and applicable sick pay provisions. Ask HR or payroll to confirm the expected pay in writing before relying on a reduced-hours plan.
Check the whole period, including what happens if it is extended. If the financial implications make the proposed arrangement difficult, raise that early so the available options can be discussed. Do not silently agree to a plan you cannot sustain.
Self-employed people, contractors, and people with several jobs may have different arrangements. Seek advice that reflects your actual working status rather than assuming a general employee example applies to every source of income.
Agree information sharing deliberately
Acas guidance on medical reports says an employer needs permission to request a report about a worker’s health. The purpose is relevant information for employment decisions, not unrestricted access to the person’s complete medical record.
Ask who will receive the report, what questions it addresses, and how you can discuss its contents with the relevant professional. A manager may need to know about working restrictions without needing every detail of therapy.
Decide what you want colleagues to be told. You might prefer a brief explanation that you are returning after treatment and temporarily working an adjusted schedule. Agree a consistent message with your manager so you are not repeatedly placed in an uncomfortable conversation.
Keep professional or regulatory obligations separate from informal workplace disclosure. If your role has additional requirements, obtain advice from the appropriate professional body, occupational health team, or legal adviser. Do not rely on a generic promise that rehab is either always reportable or never relevant.
Address the pressures that will still be there
If workload, conflict, bullying, or unpredictable hours contributed to difficulty, returning to the identical situation needs careful discussion. Treatment may improve coping, but it does not automatically change the working environment.
The Health and Safety Executive’s guidance explains employers’ responsibility to assess and act on work-related stress risks. Describe the work factors concretely so that the discussion can address the conditions of work as well as individual support.
Acas’s mental health adjustment guidance gives examples involving hours, tasks, communication, environment, and support. Appropriate changes depend on the person and job. A mental health condition can meet the legal definition of disability, but do not assume every addiction or treatment history creates identical legal rights.
Ask for the adjustment that addresses the actual problem. If unpredictable calls are difficult, agree a communication method. If meetings leave no time for treatment appointments, address scheduling. If responsibilities exceed the agreed hours, clarify priorities and what can wait.
Include the London commute in the working day
A return plan should account for the journey as well as time at a desk or worksite. Consider crowds, changes between lines, travel duration, and how the commute fits around medication, meals, sleep, and appointments.
Explore whether a different start time, occasional remote work, or another route would be useful and feasible. These are matters to discuss, not arrangements to assume the employer can always provide.
Use current TfL accessibility information if physical access is relevant. If you plan a practice journey, choose a time and format consistent with clinical advice rather than treating it as a test of whether you are “recovered.”
Protect continuing treatment
Put follow-up appointments into the plan before accepting a full calendar of work commitments. Include travel and preparation time where needed. Ask who can approve time away and what notice or documentation the workplace requires.
Keep clinical support distinct from an employee assistance program. An EAP may offer useful support, but its scope and session limits vary. Confirm what it provides before assuming it can replace the clinician or program already involved in your care.
The aftercare guide helps organize follow-up. If relapse prevention is part of your treatment, use the relapse prevention guide to discuss work-related situations with your therapist, such as business entertainment, exhaustion after travel, or isolation when working from home.
Prepare for social situations without rehearsing an entire explanation
You may encounter invitations, questions, or routines associated with the period before treatment. Plan a few responses that feel natural, such as declining an evening event or suggesting another meeting format. You do not owe colleagues a detailed clinical account to make an ordinary social choice.
Identify someone you can contact after a difficult workday. This might be a clinician through the agreed route, a support group, or a trusted person. Make sure the plan does not depend on one colleague being constantly available.
If work involves alcohol-centered events, discuss how to handle those duties with your care team and manager where appropriate. The aim is an arrangement that fits the job and treatment plan, rather than relying on improvisation each time an invitation arrives.
Review the plan before difficulties accumulate
At the agreed review, discuss what is working, what remains difficult, and whether treatment or work circumstances have changed. Bring specific examples: missed breaks, tasks completed comfortably, increasing fatigue, or difficulty attending appointments.
If the plan needs revision, raise it promptly. A slower progression is not automatically a failure, and a successful first week does not oblige you to accelerate beyond the agreed advice. Keep the discussion focused on sustainable functioning and the actual demands of the role.
If you disagree with an employment decision or need help understanding your position, contact Acas, a union representative, or an appropriately qualified adviser. A return from rehab should have clear clinical and workplace responsibilities, with a practical route to resolve problems before they undermine continuing care.
