How does contributory negligence reduce my work accident compensation?

What is contributory negligence in a work accident claim?

Your own actions or omissions contributed to the accident or its severity; assessed as a percentage; compensation reduced accordingly

How is the percentage decided?

Expert evidence; comparison of respective fault; employer's breach weighed against claimant's departure from reasonable care; factors: training provided, rule in place, claimant's experience, nature of risk

Common situations where contributory negligence is raised

Not wearing available PPE; operating machinery incorrectly despite training; ignoring a clear safety instruction; rushing to complete a task; horseplay; working under the influence of substances

Is contributory negligence the same as volenti (voluntary assumption of risk)?

No — volenti is a complete defence; very rarely succeeds in employment cases — ICI v Shatwell [1965]; contributory negligence is much more common and partial

Typical reductions in work accident cases

0–15% for minor procedural failures; 25–33% for more significant departures; above 50% rare where employer clearly in breach

Related questions

Can I still claim if I was partly to blame?

Yes. Contributory negligence reduces your award — it does not bar your claim entirely.

What if my employer says I was 100% to blame?

This is a denial of liability, not contributory negligence. Your solicitor will challenge it through evidence and expert opinion.
