Reporting it and the claim process
Repetitive strain from assembly lines is common in manufacturing. Many states recognize cumulative injuries, though they are often reviewed closely. Your report should describe your tasks in detail. Instead of writing that your wrist hurts, try something like: I install clips on door panels, about one every few seconds, pushing with my right thumb and twisting my wrist, for most of a long shift. That kind of detail shows how the work and the pain fit together.
If a tool, fixture or line was designed or maintained by another company, note it. Tool design can matter for safety and sometimes for third-party questions.
Deadlines to report and to file vary by state, and for gradual injuries may depend on when you realized the pain was work-related. Check with your state's workers' compensation agency soon. If a coworker on the same station has similar pain, that is worth noting too, without speaking for them.
Keep your report, symptom diary, notes on line speed and overtime, and all medical records.
Getting medical care
A licensed clinician can evaluate your symptoms and decide what care fits. People are often seen in occupational medicine, hand and upper extremity care, orthopedics or physical therapy. Bring your task description and symptom diary to the visit. If you can, show the clinician the motion you repeat; it is often easier to demonstrate than to explain.
Tell the clinician about your assembly tasks. Some states and employers have rules about which provider you see first, so ask your employer or the adjuster. If you are referred to hand therapy or a specialist, ask the adjuster how approval works so care is not delayed.
If medication or supplies are prescribed, ask the pharmacy and adjuster how work-injury prescriptions are handled. Home delivery is often available.

When people often talk to an attorney
- Your claim is denied because there was no single accident.
- Pain is blamed on hobbies or age.
- You face discipline for not keeping up with the line.
- Specialist care is delayed.
- A tool or fixture from another company contributed.
- Restrictions from your clinician are not being followed on the line.

Recovery and going back to work
Follow your care plan and track symptoms. Hand and wrist tendons can take time to settle, and symptoms may flare when you go back to full speed. Write down which motions and how many hours bring the pain back, so your clinician can adjust the plan.
Ask for restrictions, like job rotation, slower pace or limits on certain motions. Share them in writing. Rotating between stations that use different muscles, a slower pace for a while, or a tool change such as a powered driver instead of a manual one are examples of adjustments some plants make. If the restrictions are not followed on the floor, raise it in writing with your supervisor or HR.
Stay in touch with your supervisor and adjuster. Let the adjuster know when you return to work, when your restrictions change and if symptoms come back. Keep copies of every work status note.

Frequently asked questions
Can tendonitis from assembly line work be covered by workers' comp?
It may be, depending on your state and the medical evidence. Repetitive injuries from work tasks are recognized in many places. Report it and ask your state's agency.
Should I report pain that built up slowly?
Yes, reporting it in writing is a good idea. Gradual injuries are a recognized type of work injury in many states. Describe your tasks clearly.
Can I ask to rotate stations?
Yes, it is reasonable to ask, and putting it in writing creates a record. Your clinician may also recommend rotation. Ask your supervisor.
What if the line speed increased?
Note when it changed and how it affected your symptoms. That detail can be useful. Include it in your report.
Can I be disciplined for not keeping up because of pain?
Rules vary, and this is a legal question. Discipline after reporting an injury is a common reason people consult an attorney. Keep records.
When should I report tendonitis from work?
As soon as you suspect it is related to work. Deadlines vary by state. Do not wait.
