Sickness Absence: Avoiding Common Employer Mistakes
Managing long-term sickness absence can be one of the trickiest aspects of employment law. Even well-intentioned employers can inadvertently create legal risk if processes are not followed carefully. A recent tribunal decision demonstrates just how easily mistakes can occur - and what employers should do to stay compliant.
The Case:
In Ntui v Lidl Great Britain Ltd, the tribunal examined whether a dismissal during sickness absence was reasonable. Central to the judgment were two key areas:
How medical evidence was obtained and assessed
Whether meaningful consultation with the employee had taken place before the decision
This case serves as a cautionary tale: tribunals will scrutinise both evidence and process, not just the outcome.
Where Employers Often Go Wrong:
Common pitfalls in managing long-term absence include:
Assuming recovery timelines - every employee’s situation is unique, and assumptions can lead to unfair treatment.
Failing to obtain updated occupational health advice - tribunals expect decisions to be informed by current medical evidence.
Not fully exploring reasonable adjustments - reasonable adjustments can prevent unnecessary dismissal and demonstrate fairness.
Accelerating capability processes due to operational pressure - rushing decisions without following structured procedures increases risk.
Key Takeaways:
Tribunals expect balanced, evidence-based decisions supported by clear communication.
Regular manager training and structured absence procedures are essential safeguards.
Documenting each step and consultation protects both employees and employers.
