Employers’ liability medical record redaction is the removal of IDs from an injured-worker file. Employers' Liability (Compulsory Insurance) Act 1969 s.1 is why the insurer holds the file at all — it requires most employers to carry this cover — and Limitation Act 1980 s.11 gives an injured worker up to three years from the date of knowledge of their injury to bring a claim, which is why these files are kept and reused for years. anonym.plus works locally and keeps the harm and treatment course the pages document.
When this applies
A work-injury case names the worker, the firm, and the treating doctor, and may stay live for years under the Limitation Act 1980 s.11 date-of-knowledge rule. To study return-to-work rates or train staff, clear those IDs first.
How anonym.plus handles it
- Load the file into anonym.plus on your device.
- It finds the worker, the firm, and the doctor.
- Incident dates and ID numbers get flagged.
- Keep the reported harm and the treatment course.
- Swap or black out the confirmed IDs.
- Save the clean copy on your machine.
What you need to provide
- The case file (PDF, DOCX, or bundle).
- An operator (Redact for legal copies).
- Optional alias map for the worker and employer.

Limitations & cautions
The employer name plus a rare injury can narrow identity at a small firm. Treat the employer as an identifier. Check that legal exhibits are scanned, since an ID can hide on an attached page.
Frequently asked questions
Is the employer anonymised too?
Yes. A small firm plus a rare harm can re-identify the worker, so the company is flagged and swapped as an identifier alongside the worker's own name.
Why do these files stay open for so long?
Limitation Act 1980 s.11 gives an injured worker up to three years from the date of knowledge of their injury, which for some conditions can be years after the incident itself, to bring a claim. The file is kept live, and reused for study, for as long as that window can still run.
Will the treatment course stay usable?
Yes. The harm and treatment course stay untouched. Only IDs change, so the file still serves return-to-work study.
