Fitness for Duty Letter Template: Ensuring Workplace Safety and Compliance

Introduction: Balancing Safety and Rights

A Fitness for Duty (FFD) letter is vital in occupational health. It formally communicates whether an employee can safely perform their job, protecting the workforce while ensuring compliance with laws like the ADA.

Why Fitness for Duty Letters Are Essential

Proper documentation benefits both sides:

  • Safety First: Prevents employees from returning before they are physically/mentally ready, avoiding re-injury or accidents.
  • Legal Compliance: Documents the process to meet ADA requirements for reasonable accommodation attempts.
  • Fairness: Ensures employment decisions are based on objective medical facts, not assumptions.
  • Clarity: Provides specific details on restrictions (e.g., "no lifting over 20lbs") to guide managers.

Key Components of an FFD Letter

A complete FFD template includes three main sections:

  • Part 1: Employer Info: Employee details, reason for referral (observed behavior/medical leave), and essential job functions list.
  • Part 2: Provider Findings: Exam date, clear "Fit" or "Unfit" opinion, specific restrictions/limitations, and duration of restrictions.
  • Part 3: Employee Acknowledgment: Signature confirming understanding of the process.
