What to do if…
a manager asks you for detailed medical information
Short answer
Pause and don’t share detailed medical history or documents directly with your manager. Ask what decision they’re trying to make, then offer only “work impact” information (or a fit note) and, if needed, a consent-based occupational health or GP report via the proper confidential route.
Do not do these things
- Do not send your full diagnosis history, medications list, test results, or screenshots from medical portals “just to be safe”.
- Do not agree on the spot to “full medical records” or to your manager contacting your GP directly without seeing exactly what will be asked and who will see it.
- Do not discuss your health in group chats or open-plan conversations — move it to writing and a confidential channel.
- Do not ignore the request completely — respond, but set boundaries and redirect it to HR/occupational health (or whoever handles medical info).
- Do not feel you have to fill gaps. “I’m not able to share detailed medical information, but I can provide appropriate evidence about work impact” is enough.
What to do now
- Ask (in writing) what they need and why.
Example: “Can you confirm what decision you need to make (absence recording, return-to-work, safety, adjustments) and what specific information you’re requesting?” - Offer “work impact” details instead of medical detail.
Share only what helps manage work safely, for example:- whether you’re fit to work right now
- what tasks you can/can’t do (and why, in plain functional terms)
- any temporary restrictions (hours, lifting, travel, screens, stressors)
- what might help (remote work, altered duties, phased return)
- Use the normal sickness evidence route.
If you’ve been off 7 calendar days or fewer, you usually self-certify using your employer’s process. If you’ve been off more than 7 calendar days, a fit note is the usual evidence and focuses on fitness for work.
If your employer insists on a clinician’s note during the first 7 days, ask who will cover any fee for that evidence. - Move “extra details” requests to the right channel.
Say: “I’m not comfortable sharing detailed medical information directly. I’m happy to provide appropriate documentation to HR/occupational health.”
If you do not have HR/occupational health, ask: “Who is the designated confidential contact for health/leave information?” - If they want a GP/doctor report, slow it down and use your consent rights.
Ask for the request in writing and check:- what questions they will ask (it should be limited to what’s needed for work)
- who will see the report
In most cases you can refuse permission, and you can usually ask to see the report before it’s sent, request corrections if inaccurate/misleading, and refuse to let it be shared. If you want to see it before it’s sent, there is commonly a time window to arrange this — don’t delay once the employer applies.
- Ask how your health information will be stored and shared.
You can say: “Please confirm how this information will be stored, who will have access, and that only the minimum necessary will be shared.” (This is especially important if your manager is asking for detail.) - Keep a brief record now.
Note the date/time, what was asked for, and what you offered instead. Save messages. After any verbal chat, email a short recap. - If the pressure continues, use your internal process.
If your manager won’t accept boundaries, raise it with HR (or the designated contact). If needed, use your grievance process: “I’m willing to provide appropriate evidence (fit note/OH/doctor report with consent), but not detailed medical information to my line manager.”
What can wait
- You do not need to decide today whether to disclose a diagnosis label.
- You do not need to consent immediately to any GP/medical report request.
- You do not need to start a formal grievance unless the pressure continues after you’ve set a boundary and redirected to the proper channel.
- You do not need to “prove” you’re unwell by sharing extra documents beyond what’s actually needed for absence/fitness/adjustments.
Important reassurance
Being put on the spot like this can feel invasive. In most workplaces, what’s needed is minimal: evidence of sickness/fitness for work and the practical impact on duties. It’s reasonable to slow the conversation down, put it in writing, and keep details limited and confidential.
Scope note
These are first steps to protect your privacy and keep work processes moving safely. Later decisions (capability processes, adjustments disputes, discrimination concerns) may need specialist advice — but you can stabilise this moment first.
Important note
This is general information, not legal advice. Workplace policy and the reason for the request matter. If your health is worsening or you’re too unwell to engage, prioritise medical care and then return to workplace documentation when you’re able.
