Case law
Leeds Teaching Hospital NHS Trust v Foster

An adjustment doesn’t need a guaranteed chance of working to count as reasonable.

The ruling

EAT: an adjustment needs only some chance of success, not a guarantee; both claims succeeded.”

An adjustment does not need a guaranteed, or even a strong, chance of removing your disadvantage to count as reasonable under the law. A lesser prospect can be enough.

  • If your employer says an adjustment "might not work" as a reason not to try it, that is not the end of the argument, the legal bar is lower than certainty.
  • In a larger organisation, the size of the workforce and how often vacancies arise are themselves evidence that redeployment had a genuine chance of success.
  • If your employer treats your sickness absence and the workplace problem behind it as entirely separate issues, get advice, that separation can itself contribute to an unfair dismissal.

The situation

A senior security inspector went off sick with stress after his relationship with his line manager broke down. He raised a grievance of bullying and harassment. It wasn't upheld. Occupational Health repeatedly said his return to work depended on resolving the underlying workplace problems, but his employer treated the sickness absence and the grievance as two separate matters and never tackled the root cause. He was promised redeployment to a role away from his old department. That promise fell through, and he was eventually dismissed after nearly two and a half years off sick.

What the tribunal found

The tribunal found the employer should have put him on its redeployment register several months earlier than it did, at a point when he had confirmed he was ready to return and Occupational Health saw no medical reason why not. On appeal, the employer argued this couldn't be a reasonable adjustment because there was no proof it would definitely, or even probably, have led to a suitable job. The tribunal disagreed, and the Employment Appeal Tribunal agreed with the tribunal: an adjustment does not need a strong or guaranteed chance of working to count as reasonable. A lesser prospect is enough. His disability discrimination and unfair dismissal claims both succeeded.
