1. What Should Happen Legally and Practically

Employers are expected to:

  • Follow their sick leave policy or any official return-to-work procedure

  • Carry out a return-to-work meeting

  • Consider reasonable adjustments, especially for mental health

  • Ensure you’re not disadvantaged or discriminated against due to your health

⚠️ Even if your employer does not follow their own policy, they are still legally obligated under:

  • Health & Safety at Work Act 1974

  • Equality Act 2010 (if your mental health condition qualifies as a disability)

  • ACAS Code of Practice on Managing Sickness Absence

2. “Phased Return to Work”?

A phased return allows you to gradually ease back into your role instead of jumping in full-time immediately.

It might include:

  • Reduced hours (e.g. half days for a week or two)

  • Fewer days per week to begin with

  • Modified duties (removing high-stress or intense tasks temporarily)

  • Working from home if applicable

It should be agreed between you and your employer — ideally after medical advice from your GP or ideally occupational health.

📌 Note: Your GP can recommend a phased return on your fit note (write: "Fit to work with adjustments").

3. Steps an Employee Should Follow for a Fair Return

Step 1: Get medical advice

  • Obtain fit to work report from your GP.

  • If you are not feeling ready to go back to work fully or if your practitioner advices a phased return, ask your GP to note on your fit note that a phased return is recommended.

  • They may also suggest specific adjustments such as less work load or different duties.

Step 2: Notify your employer

  • Send them your updated fit note and a request to discuss your return.

Step 3: Attend a Return-to-Work Meeting

This meeting should cover:

  • How you're feeling.

  • Any ongoing symptoms or needs

  • What support or adjustments might help

  • Agreement on a timeline to return full-time

➡️ If no meeting is offered, you can request one in writing.

4. What Is Your Employer Responsible For?

By law, your employer should:

  • Assess risks to your health (especially if you’re returning with a known condition)

  • Consider reasonable adjustments under the Equality Act 2010

  • Respect your medical advice and involve occupational health if needed

  • Avoid pressuring you to return full-time before you're ready

  • Handle your information confidentially

✅ If they have Occupational Health services, they should offer you an appointment to support a safe return.

5. What If Your Employer Does Not Have Occupational Health?

Even if your employer doesn’t have a formal Occupational Health (OH) department, they are still legally responsible for ensuring a safe and fair return to work after sickness absence — especially when it involves mental health.

Here’s what that means:

a. Legal Responsibility Still Applies

Under:

  • The Health and Safety at Work Act 1974

  • The Equality Act 2010

  • The ACAS Code of Practice on Managing Sickness Absence

They must still assess risks and provide reasonable support.

b. What Employers Can Do Instead

If there's no in-house OH, employers can still:

  • Request written advice from your GP (via fit notes or letters)

  • Ask for your consent to contact your GP under the Access to Medical Reports Act 1988

  • Arrange a private independent medical assessment

  • Hold a proper return-to-work meeting with HR or your manager

  • Adjust your workload or hours in line with reasonable expectations

✅ You may also provide your own medical documentation — they are legally required to take this seriously when planning your return.

c. When Employers Avoid Taking Action

If an employer refuses to:

  • Consider your GP’s advice

  • Make reasonable adjustments

  • Discuss your return in good faith

➡️ You may be able to:

  • Raise a formal grievance

  • Claim disability discrimination (if your condition qualifies)

  • Contact the Equality and Human Rights Commission (EHRC)

  • Escalate to ACAS or take legal action via a tribunal

d. How You Can Proactively Protect Yourself

  • Request a return-to-work meeting in writing

  • Bring a copy of your fit note and any GP recommendations

  • Ask them how they plan to fulfil their duty of care

  • Keep a written record of all communication and meetings

⚠️ 5. What If Your Employer Tries to:

Situation Your Rights Suggested Action

❌ Push you to return full-time ➡️ Ask for a phased return backed by GP advice

❌ Refuse a return-to-work meeting ➡️ Request one in writing and refer to their policy

❌ Deny reasonable adjustments ➡️ Remind them of their duty under the Equality Act

❌ Discriminate, punish, or dismiss you ➡️ Raise a grievance or seek legal advice immediately

📌 You can contact ACAS, your union, or a solicitor for advice.

6. How to Prepare and Stand Up for Yourself

✅ Know Your Rights

  • You don’t need to rush.

  • You are entitled to a safe, fair, and supported return.

  • If your health condition qualifies as a disability, the company must make reasonable adjustments.

✅ Keep Records

  • Save all emails, fit notes, and meeting notes.

  • You can bring a support person (e.g., union rep or trusted colleague) to meetings.

✅ Communicate Clearly in Writing

  • You can say: “I’m committed to returning to work, but I’d like to do so gradually, with adjustments. My GP has recommended a phased return. Can we arrange a meeting to plan this together?”

🆘 If Your Employer Fails to Support You

  • Contact ACAS: 0300 123 1100

  • Seek legal advice

  • Consider raising a formal grievance

  • Consult your union (if a member)

  • Keep a record in case of legal action or a tribunal

💬 A Final Word

If you're navigating a return to work after mental health leave, please remember this:

You’re not weak for needing time to heal. You’re not difficult for asking for support. You’re not alone — and you have rights.

Taking care of your mental health is not just valid — it’s essential! You deserve a workplace that sees you as a whole person, not just a role to fill. Advocating for yourself may feel daunting, but it's also powerful. And you don’t have to do it alone — support is out there.

Be kind to yourself. Take one step at a time. You’ve already done something brave by being here. 💛
