Quick Summary
- Shoulder impingement occurs when tendons in the shoulder become compressed or irritated, often from repeated overhead or awkward-position movement
- Unlike a single-incident injury, it typically develops gradually — which changes how the claim time limit works and what evidence matters most
- Repetitive tasks involving overhead reaching, prolonged awkward postures, or repeated lifting without adequate job rotation or ergonomic assessment are common causes
- A claim depends on whether your employer failed to properly assess and manage the risk of repetitive strain in your role
What is shoulder impingement?
Shoulder impingement syndrome happens when the tendons of the rotator cuff — the group of muscles and tendons stabilising the shoulder joint — become compressed or irritated as they pass through a narrow space in the shoulder, usually during overhead or repeated arm movement. It typically causes pain, particularly when lifting the arm above shoulder height, and can progressively worsen if the underlying cause isn't addressed.
How does this condition typically develop at work?
Unlike an injury from a single fall or lifting incident, shoulder impingement usually builds up gradually from repeated strain. Common workplace patterns include:
- Repeated overhead reaching or lifting, such as stocking high shelves or overhead assembly work
- Prolonged awkward arm positions with no job rotation or adequate breaks
- Repetitive pushing, pulling, or lifting tasks that place sustained strain on the shoulder
- Poorly designed workstations or tasks that force an unnatural or sustained arm posture
What makes an employer responsible for this kind of injury?
Employers have a duty to assess risks arising from repetitive tasks, including musculoskeletal risks like shoulder impingement, and to take reasonably practicable steps to reduce them — such as job rotation, ergonomic equipment, adjusted work rates, or changes to task design. Where an employer fails to properly assess a role involving obviously repetitive overhead or awkward-position work, and a worker develops a condition like shoulder impingement as a result, this can support a claim.
Does this mean any employer whose staff do repetitive work is automatically liable?
No — as with other cumulative-strain conditions, the question is whether the employer took reasonable steps to identify and manage the risk, not whether repetitive work exists at all. A properly assessed role with reasonable rotation and ergonomic consideration is a different position to one where an obvious repetitive strain risk was simply ignored.
How does the time limit work for a condition that develops gradually?
Because shoulder impingement typically builds up over time rather than from a single incident, the three-year time limit under the Limitation Act 1980 generally runs from your "date of knowledge" — when you first knew, or reasonably ought to have known, that your symptoms were linked to your work — rather than from when you first noticed shoulder pain.
What evidence supports a claim?
- A description of the specific repetitive tasks and postures involved in your role
- Medical records documenting the onset and progression of your symptoms
- A diagnosis, typically supported by clinical examination and sometimes imaging such as an ultrasound or MRI
- Evidence of whether a risk assessment covering repetitive strain existed for your role, or whether one was needed but missing
- Details of any colleagues who developed similar symptoms doing the same tasks
What if I need surgery or physiotherapy for shoulder impingement?
Treatment often starts with physiotherapy and activity modification, but more persistent cases can require injections or, in some instances, surgery (such as subacromial decompression) to relieve the compression. Where more intensive treatment is needed, this is a relevant factor in valuing a claim, alongside ongoing pain and any lasting restriction on overhead movement.
Frequently asked questions
Can I claim if my shoulder pain built up over months rather than from one incident?
Yes — cumulative-strain conditions like shoulder impingement are a recognised basis for a claim, provided your employer's failure to manage the repetitive risk can be shown to have caused or contributed to it.
Does this only affect certain jobs?
No — while overhead or repetitive-reach roles are more commonly affected, shoulder impingement can arise from a range of repetitive tasks involving the arm and shoulder, and is assessed on the specific demands of your role.
What if my employer says shoulder pain is just wear and tear?
This is exactly the kind of question a solicitor will investigate — whether the specific demands of your role, and any failure to manage that risk, materially contributed to your condition.
Developed shoulder pain from repetitive work tasks?
A specialist solicitor can assess whether your role's demands and your employer's response support a claim.
