Jones v Post Office [2001] IRLR 384 is a UK labour law case, under the Disability Discrimination Act 1995.

He became diabetic and insulin dependent and was removed from driving duties.

Pill LJ said "Where a properly conducted risk assessment provides a reason which is on its face both material and substantial, and is not irrational, the tribunal cannot substitute its own appraisal."

This case has been subject to considerable academic criticism, for introducing (without any apparent statutory authority) a "reasonable range of responses" test.

A number of cases after have limited and tacitly undermined its effect.
