Case details

Key facts

  • The claimant was a nurse employed by the respondent to provide clinical cover at police custody suites.
  • The claimant had bilateral knee replacements and a hip replacement and could not kneel to perform CPR.
  • The respondent obtained occupational health advice that the claimant could not safely perform CPR on her knees.
  • The claimant was dismissed on grounds of capability after a risk assessment and capability hearing.
  • The tribunal found the respondent genuinely believed the claimant was incapable of performing CPR and acted reasonably.

Timeline

  1. Employment commenced

    The claimant started work as a Forensic Custody Healthcare Professional (later Forensic Practitioner) for the respondent.

  2. First occupational health advice

    Dr Brennan advised the claimant was fit to work with recommendations, but did not mention her inability to kneel.

  3. Occupational health report triggers concerns

    A report noted the claimant's osteoarthritis and joint replacements, prompting the respondent to investigate her ability to perform CPR.

  4. Immediate Life Support course passed

    The claimant passed a course performing CPR on a dummy at waist height, not on the floor.

  5. Risk assessment investigatory meeting

    The claimant confirmed she could not kneel but felt she could manage in an emergency with a cushion.

  6. Further occupational health advice

    Dr Brennan stated he had never seen anyone with two knee replacements perform safe CPR and suggested a waiver if the claimant wanted to demonstrate.

  7. Ill health capability interview

    A comprehensive discussion about the claimant's ability to perform CPR; no adjustments were identified.

  8. Capability hearing

    Chaired by Gareth Hart, the hearing considered the claimant's ability to perform CPR; the claimant said she could delegate chest compressions.

  9. Dismissal letter sent

    The claimant was dismissed on grounds of incapability due to inability to safely perform CPR.

The outcome

The tribunal dismissed the claim of unfair dismissal.

The key reasons were:

  • The employer genuinely believed the claimant could not perform CPR safely, based on occupational health advice and the claimant's own admission.
  • The employer carried out a reasonable investigation, including a risk assessment and capability hearing.
  • The dismissal was within the range of reasonable responses for a capability dismissal.

No compensation was awarded as the claim failed.

Lessons & takeaways

  • Employers must have a genuine belief, based on reasonable grounds, that an employee is incapable of performing a core function of their role before dismissing on capability grounds.
  • Occupational health advice that an employee cannot safely perform a key task is strong evidence for a capability dismissal, especially if no reasonable adjustments are identified.
  • Employees should proactively suggest adjustments if they believe they can perform the role with support, as failure to identify adjustments can weaken a claim.
  • A fair process, including consultation and a capability hearing, is essential to show the employer acted reasonably.
  • Length of service (here 2 years) may affect the range of reasonable responses, but a short service does not automatically make a dismissal unfair if the employer has followed proper procedure.

When a physical limitation becomes a capability issue

This case highlights the difficult balance between an employee's physical limitations and the essential requirements of a safety-critical role. The claimant, a forensic custody healthcare professional, had undergone bilateral knee replacements and could not kneel to perform CPR on the floor. Despite passing a CPR course on a waist-height dummy, the employer's occupational health advisor concluded that performing CPR on the floor was unsafe. The employer dismissed her on capability grounds.

What the employer did right

The tribunal found that the employer acted reasonably throughout. It obtained occupational health advice, conducted a risk assessment, held an investigatory meeting and a capability hearing, and genuinely believed the claimant could not safely perform CPR. The claimant suggested she could delegate chest compressions, but the employer considered that this was not a reasonable adjustment for a lone worker in a custody suite. The tribunal noted that the employer had explored alternatives but none were viable.

Why the claim failed

The claimant argued that the employer should have accepted her offer to demonstrate CPR with a cushion or to delegate. However, the tribunal accepted that the employer's decision was within the range of reasonable responses. The key factor was the occupational health advice that she could not safely perform CPR, and the employer's genuine belief that this was a core function of her role. The tribunal also noted that the claimant had only two years' service, which meant the employer was not expected to go to extraordinary lengths to accommodate her.

What this means for similar claims

For employees with physical limitations, this case underscores the importance of engaging with occupational health and suggesting practical adjustments early. For employers, it confirms that a thorough process, supported by expert medical advice, can justify a capability dismissal even when the employee is willing and able to perform the role in a modified way. The decision also reinforces that the 'range of reasonable responses' test gives employers a degree of latitude in safety-critical roles.
