Light duty work restrictions are written limits a clinician places on the tasks a person may perform at work, usually capping how much weight they lift, how long they stand, or how many hours they work. Employers match available tasks to those limits; workers follow them to avoid setbacks. This guide covers how restrictions get written, how long they last, and what to do when a job task falls outside them.
It is written for both sides of the conversation: the HR manager sorting out a modified-duty assignment, and the employee trying to decode a note full of phrases like occasional lifting and sedentary. Rules differ by state, by employer policy, and by whether the underlying condition is work-related, so treat this as general information rather than legal or medical advice.

What Are Light Duty Work Restrictions?
Light duty work restrictions are clinician-imposed limits on what a person can do on the job while recovering from an injury, surgery, or illness. The limits are written down, usually in pounds, body positions, hours, or tool use, so the employee can work without aggravating the condition. Light duty is a modified version of the employee’s normal role, and it exists so recovery and pay continue at the same time.
It is not the same as full duty, where a person is released with no limits, and it is not the same as total disability, where the person is medically unable to work at all and stays off entirely. A person can work a reduced number of hours, avoid specific tasks in an otherwise full role, or do entirely different work, and all three count as restricted work.
The phrase gets used loosely, which is why definitions drift. For this guide, light duty work restrictions mean the written functional limits themselves. The assignment that results, whether that is the same job with tasks removed or a different job entirely, is a separate question that employers answer with a physical demands analysis and a written offer.
Who qualifies depends entirely on why the restrictions exist. Workers’ compensation claims, employer disability programs, the Family and Medical Leave Act, the Americans with Disabilities Act, and the Pregnant Workers Fairness Act all use slightly different processes, and a state workers’ compensation office and a private employer’s HR team may define the term differently.
What Light Duty Work Restrictions Look Like in Writing
Restrictions arrive as a work status report, a physical capacity questionnaire, an attending physician’s statement, or a set of instructions typed onto a form. The format matters less than the content: a usable document names specific limits, states how long they last, and gives a date for reassessment.
A vague note saying light duty only is the single most common problem HR teams run into. It gives the employer no way to match a task to a limit, and it gives the employee no way to tell whether a specific job function is allowed. A note that reads no lifting over 20 pounds, occasional lifting only up to 20 percent of the shift, no ladder or stair climbing, up to six hours per day, reassess in four weeks can be matched against a job in minutes.
Two terms cause most of the confusion, and both come from federal physical demand guidelines. Occasional means under a third of the working day. Frequent means between a third and two-thirds of the day. The weight categories are sedentary (lifting no more than about 10 pounds), light (up to about 20 pounds), and medium (up to about 50 pounds), and clinicians pick one plus a frequency qualifier. Occasional light lifting and frequent medium lifting are very different jobs, and treating them as the same is how employees get injured returning to work.
Why Employers and Employees Ask About Light Duty
Recovery from a work injury is the most common reason. A back strain, a shoulder injury, or a hand fracture limits lifting and reaching, and the employee needs a modified assignment until symptoms settle. A return-to-work program puts that modified assignment in writing, sets a review date, and closes it out with a release to full duty or a permanent restriction.
Surgery and scheduled medical treatment produce the same need on a predictable timeline. A rotator cuff repair or a hip replacement generates restrictions for weeks at a time, and the employer needs to know exactly which tasks are off the table and for how long.
Pregnancy creates restrictions that are about capacity rather than injury. Limits on lifting heavy objects, standing for long stretches, or working around known hazards are common in the later months, and the Pregnant Workers Fairness Act, in effect since 2023, requires reasonable accommodations unless they create an undue hardship.
Chronic conditions and mental health also generate written limits. Multiple sclerosis, severe asthma, epilepsy, and post-surgical recovery from a psychiatric hospitalization all show up as medical restrictions on a work status report. Employers treat these under disability accommodation rules rather than workers’ compensation, but the drafting exercise is the same.
Finally, some restrictions come from a clinician who has never seen the job and is working from a generic template. That is where a physical demands analysis, or a conversation between HR and the treating provider, saves everyone time.
What Can Light Duty Actually Include?
Restrictions are not one category. They apply to force, to body position, to repetition, to pace, to schedule, and to environment, and a good document addresses each one separately. A restriction set that names a weight limit and nothing else is incomplete, and light duty work restrictions written that way tend to generate the same disagreement twice. Below is the mapping most useful when someone asks what a phrase actually permits on the floor.
| Restriction type | What it means in plain English | Sample tasks that usually fit |
|---|---|---|
| Reduced lifting or carrying | A weight cap, often 10, 20, or 50 pounds, sometimes with a frequency limit | Refilling shelves under the cap, sorting mail, carrying paperwork, light machine operation |
| Limited standing or walking | Standing or walking allowed only a portion of the shift, with breaks | Seated cashier, seated dispatch, counter work, charting at a workstation |
| No overhead work | No reaching above shoulder height, no ladders, no stair climbing | Ground-level stocking, packing station, desk-based data entry |
| No kneeling, squatting, or bending | Body must stay upright; no working at floor level | Bench work, seated assembly, sorting bins at waist height |
| No repetitive or forceful motion | Limited repeated wrist, elbow, or shoulder movement, or limited grip force | Typing with breaks, assembly at a fixture, tool use under a grip limit |
| No vibrating or impact tools | No jackhammers, drills, saws, compactors, or handheld power tools | Hand finishing, inspection, plant watching, equipment monitoring |
| No driving | No operation of company vehicles, including short local routes | Dispatch, scheduling, yard observation from the ground, warehouse support |
| Reduced hours or mandatory breaks | A cap on hours per day or week, or scheduled breaks at fixed intervals | Four- or six-hour shifts, part-time schedules, paced customer contact roles |
| Avoidance of specific tasks | Named duties are off limits regardless of weight or hours, often for allergy or exposure reasons | Reassignment away from solvents, chemicals, dust, or known allergens |
| Modified equipment or workstation | Specific accommodation, such as a sit-stand desk, anti-fatigue mat, or ergonomic keyboard | Most clerical and service work with a few hours of setup |
Remote or hybrid work has become its own category. For an office role, working from home for a set number of days a week is often the cheapest accommodation available, and many modified-duty arrangements now specify the days and the hours rather than simply saying remote eligible.
One more note for HR teams: restricted work usually still counts as a days-away-from-work record. The Occupational Safety and Health Administration generally treats a day on light duty as a recordable day, which means light duty hours can still land on the OSHA 300 log. Confirm the current rule with your own safety officer, since recordkeeping guidance changes.
How to Write and Document Work Restrictions
Good documentation is what separates a smooth return from a three-week argument. The person writing the restrictions, whether that is a clinician, an occupational health nurse, or an HR manager summarizing a conversation, should capture the same set of information every time.
A restrictions checklist you can reuse
- Functional limits. State them as measurable numbers: a weight cap in pounds, a percentage of the shift for lifting, a maximum standing time, an hour cap per day.
- Position and motion limits. Name what is prohibited, such as overhead reaching, kneeling, stair or ladder climbing, repetitive wrist motion, or vibrating tools.
- Tasks explicitly excluded. List the named duties the person may not perform, including driving or specific machines.
- Work environment. Note any exposure restriction, temperature limit, or requirement for seating or a modified workstation.
- Duration and review date. Give an end date or a review interval, such as reassess in three weeks or up to eight hours per day for six weeks.
- Accommodation support. Specify equipment, breaks, a modified shift, or a change in reporting line that the employer is expected to provide.
- Escalation contact. Name the person who answers restriction questions and how to reach them.
- Confidentiality and records handling. State that the medical document goes to HR or occupational health rather than the direct supervisor, and that the supervisor receives only the restrictions they need to accommodate.
HR should then record four more things: the date the restrictions were received, which essential job functions they touch, which supervisor was told, and which accommodation was offered in response. That single line of documentation answers most disputes later, because the question is almost never about the medical facts. It is about who said what and when.
Keep the medical document itself separate from the operational record. The manager needs to know the employee cannot lift over 20 pounds; the manager does not need the diagnosis. Handing over the whole packet is a common and avoidable privacy mistake.
How Employers Should Evaluate an Accommodation Request
Employers should treat every request as a documented, step-by-step process with a written answer at the end. A six-step approach works for workers’ compensation modified duty and for disability accommodation alike, even though the legal frameworks differ.
- Acknowledge the request in writing. Confirm receipt, name the person handling it, and give a date by which you will respond.
- Review the documentation. Read the restrictions as written and list the limits one by one. Ambiguity in the note is a reason to ask the clinician a question, not a reason to guess.
- Identify the essential job functions. Compare the current role, or the target role, against a written job description or a physical demands analysis. If no written description exists, build one.
- Match each function to each limit. Mark every function as clearly permitted, clearly prohibited, or adjustable with an accommodation.
- Consult when needed. For workers’ compensation, involve occupational health, the claims adjuster, or a nurse case manager. For disability accommodation, run the interactive process and document each step, including any undue hardship analysis.
- Communicate the decision in writing. State the assignment, hours, pay rate, supervisor, equipment provided, start date, and review date. Send the same summary to the employee and the supervisor.
Two things trip up otherwise careful employers. The first is a vague offer, where someone says there is work available without listing the tasks, hours, or rate, and the employee has no way to know whether it fits. The second is inconsistent enforcement, where HR honors the restrictions and the shop floor does not. A short written task list given to the supervisor at assignment time prevents both.
Employees have obligations too. They follow the restrictions as written, they report a change in symptoms, and they ask for an accommodation through the process rather than quietly adapting on their own. An employee who modifies a workstation without asking creates a documentation gap that is hard to close later.
Light Duty vs. Modified Duty vs. Full Duty
The vocabulary changes from one insurer or employer to the next, so the practical question is always the same: what can this person safely do, and what has the paperwork cleared. Here is how the common terms differ in practice.
| Work status | Who sets it | Typical duration | What happens to pay |
|---|---|---|---|
| Full duty | Treating clinician, or HR for a non-medical reason | Permanent from the start | Full wages, no offset |
| Light duty | Clinician, delivered through a work status report | Weeks to a few months | Full wages if the assignment is the same role; wage-loss benefits often make up part of a gap if the role or hours differ |
| Modified duty | Employer or insurer, within the clinician’s limits | Until the review date or a release | Depends on the written offer; hourly and salaried staff can be treated very differently |
| Sedentary duty | Clinician, using a physical demand category | Short, often post-operative | Usually reduced hours or a seated role |
| Off work entirely | Clinician, for total inability to work | Until the clinician releases it | Wage-loss benefits replace a portion of pre-injury wages, not all of it |
A release to full duty closes the file. A permanent restriction, which is a set of limits that will not improve with more time, keeps the modified assignment in place indefinitely and often triggers a benefits review as well. The distinction matters because an indefinite light duty assignment and a temporary one are treated very differently by insurers and by managers planning coverage.
How Long Do Light Duty Restrictions Usually Last?
Duration follows the condition and the treatment plan, not a standard calendar. A uncomplicated soft tissue injury may resolve in three to six weeks. A shoulder replacement runs a year or more, and each phase of rehab carries a different limit. Time alone is not the measure; functional improvement is.
Review dates are the mechanism most employers get wrong. A restriction document without a review date becomes an open-ended accommodation by default. Set the date at assignment, put it in the offer letter, and calendar it. Light duty work restrictions are designed to be revisited, and a process that never reopens them drifts into something nobody chose.
When progress stalls, a party may request an independent medical exam or a functional capacity evaluation. The functional capacity evaluation is a measured, standardized test of what the person can lift, reach, sit, and stand, and it often resolves a dispute that months of medical opinions have not. Maximum medical improvement, or MMI, is the point at which the treating clinician says further treatment will not improve the condition, and it is where temporary wage-loss benefits typically end and a permanent impairment rating process begins.
Track restrictions in three buckets. Temporary restrictions carry an end date. Extended restrictions carry a review date and a note about what is expected at the next review. Permanent restrictions carry neither, and they usually need a benefits review to go with them.
What to Do When Restrictions Are Not Possible
Sometimes the honest answer is that no job at the organization fits the restrictions, because the essential functions of every available role exceed the limits. That is a real outcome, and the response is a documented search rather than a quiet denial.
- Search and document. Look at other departments, other shifts, and remote arrangements, and record what was considered and why it did not fit.
- Consider an alternative assignment that is temporary and does not displace another employee without process.
- Explore leave. Short-term disability or medical leave may cover the gap, and FMLA may apply for a serious health condition.
- Look at vocational rehabilitation, which in workers’ compensation can provide retraining when suitable work is not available.
- Coordinate with benefits and, where needed, legal counsel before any decision that affects wage-loss benefits.
On the employee side, the recurring pressure point is a supervisor asking for help outside the written limits. Workers describe the same line almost word for word: just do this one lift, just cover this one shift, it will only take a minute. A calm written response is more effective than a refusal in the moment.
Something close to this works, and it puts the request back on paper: My current work status report limits me to lifting no more than 20 pounds and no more than six hours per day. I am not able to move that pallet. I am asking for a second person or a mechanical aid, and I am copying my manager and HR so the accommodation is on record. If those options are not available, please confirm in writing that I should not perform the task.
Workers on compensation forums also describe the reverse problem, where a manager insists restrictions are honored in HR but ignored in the aisle. A personal daily log of tasks performed, pain levels, missed breaks, and supervisor comments gives a case something concrete. Sending a time-stamped email to the supervisor and HR the same day puts the employer on notice without an argument.
If the problem does not resolve internally, the escalation path typically runs through a written dispute, a grievance procedure, the state workers’ compensation agency, or an attorney. Anyone weighing a refusal should get advice first, because a flat refusal of suitable work can be treated as a refusal of benefits.
How Employees Can Ask for Modified Work
Employees do better when the request is concrete and arrives in writing. A short, specific ask is far easier for HR to approve than a general description of a hard week.
Start with the medical side. Ask the treating clinician for written instructions that list functional limits, duration, and a follow-up date, and ask specifically for a work status report rather than a general letter. A clinician who has never seen the job will write to a template, so offer the job description or a list of physical demands.
Then map the ask to the job. List the essential job functions, mark the ones clearly outside the restrictions, and mark the ones that might work with an accommodation. This shows HR you have thought about the solution rather than just the problem.
Send the request to HR in writing, keep a copy, and ask for a written response. If an offer arrives, check each listed task against each restriction before accepting. Matching duties to limits one by one is the fastest way to spot an assignment that looks lighter but is not.
A few practical notes. Keep your own copy of every document, including the offer letter with its hours, rate, and review date. Track what you actually did each shift. And if the restrictions change, get a new written document rather than assuming the old one still applies.
Frequently Asked Questions
How many hours can you work on light duty?
The limit comes from your clinician, not from a rule. Work status reports commonly cap a person at four, six, or eight hours per day, sometimes for a fixed period such as six weeks. Working more hours than the note allows is working outside your restrictions, and wage-loss benefits can be affected as a result. If the note does not state an hour cap, ask the clinician or employer to confirm one in writing before you pick up extra shifts.
Can my doctor restrict me to light duty?
Yes. A treating clinician can issue a work status report limiting your duties, the weight you lift, your hours, or specific tasks, and that report is the document an employer works from. For it to be useful, it should list measurable limits, a duration, and a review date. A note that only says light duty usually has to go back to the clinician for clarification, which delays the whole process.
What are examples of light duty tasks?
Typical tasks include desk-based clerical or data entry work, seat-based cashier and customer contact roles, refilling stock shelves under a stated weight cap, packing at a bench, equipment monitoring, yard observation from the ground, chart review in healthcare, dispatch, and light machine operation with a vibration limit. What makes a task light duty is that it fits every restriction in the note, not that the job title sounds easier.
Can an employer refuse to provide light duty work?
Under most workers’ compensation systems, an employer is required to offer suitable work that fits the employee’s restrictions, and the insurer keeps paying benefits if no suitable work exists. The employer does not have to create a position that did not exist before the injury, and many use an official hiring freeze as a reason. What they do have to do is document the search for suitable work, so ask for that in writing if the answer is no.
What happens if I refuse a light duty offer?
It depends on whether the offer is a bona fide one. If the work genuinely fits your restrictions and the offer is made in writing with hours, pay, and tasks listed, refusing it can be treated as a refusal of suitable work, and temporary wage-loss benefits may be suspended or ended. If the offer conflicts with your restrictions, the hours are not comparable, or there is no clear written description, refusing is harder to characterize as a refusal. Get advice before declining.
Is light duty counted as restricted work for OSHA?
Generally, a day on light duty still counts as a day of work for injury recording, so restricted days typically appear on the OSHA 300 log as days away from work. Work that is purely administrative or office-based is treated differently from jobs where the injury happened in a physical environment. Recordkeeping rules are periodically updated, so confirm the current treatment for your specific situation with your own safety officer.
Conclusion: Start With Clear Restrictions and a Review Date
Most problems with light duty work restrictions come from vagueness, not from anyone’s judgment. Four things prevent nearly all of them.
Get the restrictions in writing, in measurable terms, instead of a note that says light duty only. Compare those limits against a written list of the essential job functions, function by function, rather than judging the job as a whole. Put a review date on the assignment, and revisit the light duty work restrictions any time the medical information changes.
For employers, that process is a short, documented search. For employees, it is a specific written request and a record of what was actually offered. Both sides work better when the paperwork matches reality.
