Going back to work after a job injury can feel like progress. It can also get complicated fast.
A return-to-work plan often involves medical restrictions, light-duty assignments, wage questions, benefits paperwork, and pressure from different directions at once. In general terms, even a small misunderstanding during this stage can affect physical recovery, workers’ compensation benefits, job protections, or all three.
In this post, you’ll learn about seven common return-to-work mistakes that can create problems for injured workers, why these issues matter, and what an attorney may help evaluate when the process starts to go sideways. If you want a broader overview of how restrictions, accommodations, reinjury risk, and job protection issues fit together, this guide to the return-to-work process after a work injury can help frame the bigger picture.

Return-to-work sounds simple on paper: the doctor releases the worker, the employer offers a position, and the employee resumes working.
Real life is rarely that clean.
Federal guidance reflects that return-to-work situations can involve overlapping legal systems. The U.S. Equal Employment Opportunity Commission explains that an employer generally cannot insist on a “100% healed” release if the employee can perform the job with or without a reasonable accommodation. The U.S. Department of Labor also notes that eligible workers using FMLA leave are generally entitled to return to the same or a virtually identical position. And the Bureau of Labor Statistics reports that, over the 2023–2024 period, private industry recorded 1.8 million cases involving days away from work and 1.1 million cases involving job transfer or restriction, with a median of 15 days of job transfer or restriction. That tells you something important: restricted-duty and modified-work issues are not unusual side questions. They are a central part of workplace injury recovery.
The challenge is that employers, insurance carriers, supervisors, HR departments, nurse case managers, and treating providers may all be using different language for the same issue. One person says “light duty.” Another says “modified duty.” Another says “full duty with common-sense caution.” Those differences can matter.
One of the most common mistakes is going back to work without a written, detailed understanding of what the treating provider is actually allowing.
A note that says “return to work” can be misleading if it does not spell out limits on lifting, standing, climbing, driving, bending, repetitive motion, overtime, or break frequency. That lack of detail can create confusion for everyone involved. A supervisor may assume “return to work” means business as usual. An insurer may argue the worker was medically cleared for broader duties than the doctor intended. And the injured worker may end up trying to guess what is safe.
This issue shows up often in disability accommodation guidance. The EEOC’s accommodation guidance explains that a doctor’s letter releasing an employee to return with restrictions can function as a request for accommodation. In other words, those restrictions are not just medical suggestions floating in the air. They may become part of an employer’s legal obligations in the workplace.
Here’s what this often means in practice: vague restrictions can lead to vague assignments, and vague assignments can lead to re-injury disputes or benefit fights later.
“Light duty” sounds reassuring. Sometimes it is. Sometimes it is just a label.
A job can be called light duty and still involve movements that aggravate the injury. For example, a worker with lifting restrictions may be placed in a role that technically avoids heavy lifting but still requires constant twisting, extended standing, frequent reaching, or repetitive hand use. A worker recovering from a concussion or traumatic brain injury may be brought back into a noisy, fast-paced environment that looks easy from the outside but creates serious symptom flare-ups. The CDC’s workplace TBI guidance notes that return-to-work timing and supports vary from person to person and may include accommodations such as rest breaks or reduced sensory exposure.
This is one reason “light duty” disputes can become legal disputes. The title of the assignment may sound reasonable, while the actual physical or cognitive demands tell a different story.
The Job Accommodation Network, funded by the U.S. Department of Labor, describes accommodations in functional terms: modified schedules, altered workstations, task restructuring, leave, reassignment of marginal functions, and other individualized changes. That framework is useful because it focuses on what the worker can safely do, not what the employer happens to call the assignment.
