Return to Work Letters for Employers
When an employee has been absent due to illness or injury, requiring a return-to-work letter before they resume duties protects both your organization and the employee. It confirms that a physician has assessed their fitness and documents any temporary limitations you need to accommodate.
This guide explains what a return-to-work letter should contain, how to handle restrictions, your accommodation obligations, and how to help employees obtain documentation efficiently.
What a Return-to-Work Letter Should Include
A proper return-to-work letter from a physician should include: confirmation of physician assessment, a statement of fitness to return (full or with restrictions), the effective date of return, any temporary restrictions or limitations, a review date for restrictions (if applicable), and the physician's name, credentials, and signature.
It should NOT include the employee's diagnosis, treatment details, or prognosis. If a letter contains this information, you should not retain it in the employee's file.
Full Clearance vs. Clearance with Restrictions
A full clearance means the employee can perform all aspects of their role without limitation. Clearance with restrictions means they can return but with specific temporary limitations that you must accommodate.
Common restrictions include: lifting limitations, reduced hours, schedule modifications, environmental requirements (quiet workspace, no extreme temperatures), and avoidance of specific tasks.
Your Duty to Accommodate
Under the Alberta Human Rights Act, you must accommodate medical restrictions to the point of undue hardship. This means exploring all reasonable options: modified duties, schedule changes, temporary reassignment, ergonomic adjustments, or phased return-to-work plans.
Document your accommodation process. If you ultimately cannot accommodate, you must demonstrate that you explored all reasonable alternatives. Failure to accommodate can result in human rights complaints and significant liability.
Creating a Return-to-Work Process
Best practice is to have a documented return-to-work process that includes: clear communication about when clearance is required, a designated contact person for the employee, a meeting to discuss restrictions and accommodations, a written accommodation plan, regular check-ins during the restriction period, and a process for updating or removing restrictions.
- Define when clearance is required in your attendance policy
- Designate a return-to-work coordinator (HR or direct manager)
- Meet with the employee to discuss restrictions and accommodations
- Create a written accommodation plan
- Schedule regular check-ins during the restriction period
- Have a process for updating or removing restrictions

Frequently Asked Questions
Can I require a return-to-work letter for every absence?
You can if your policy specifies it, but best practice is to require it only for absences of 3+ days, safety-sensitive roles, or after surgery/hospitalization. Apply the requirement consistently.
What if the restrictions make the job impossible?
You must explore all reasonable accommodations before concluding undue hardship. This may include temporary reassignment, modified duties, or a phased return. Document your efforts.
Can I require a specific doctor or form?
You can provide a preferred form, but you cannot require the employee to see a specific doctor. You must accept documentation from any licensed physician, including virtual providers.
How long should I accommodate restrictions?
For as long as the physician specifies, typically 2-4 weeks with a review date. If restrictions are extended repeatedly, you may request updated documentation.
