The legal issue
The tribunal had to decide whether Marks and Spencer acted reasonably in dismissing the claimant for capability, given that her absence was caused by safety concerns at work which the employer had not adequately investigated or addressed.
The outcome
The tribunal decided that the claimant was unfairly dismissed. The key reason was that Marks and Spencer did not investigate the safety concerns that contributed to her anxiety and depression before deciding to dismiss her. A 25% Polkey reduction was applied for the possibility that dismissal would have occurred anyway after a proper investigation.
Compensation breakdown:
- Basic award: £2,213.73
- Compensatory award: £12,790.68 (before Polkey reduction)
- Total after 25% Polkey reduction: £15,004.41
Lessons & takeaways
- Employers must investigate the root cause of an employee's sickness absence, especially if it relates to workplace safety concerns.
- Relying solely on occupational health reports without addressing underlying issues can make a capability dismissal unfair.
- A Polkey reduction may apply if the tribunal believes dismissal would have happened anyway after a fair process.
- Employees should raise safety concerns in writing and request that they be investigated before any dismissal decision.
What this case shows in practice
This case highlights the importance of employers investigating the underlying causes of an employee's long-term sickness absence. The claimant, a part-time customer assistant at Marks and Spencer, began her absence due to anxiety and depression following a customer incident where she confronted a shopper not wearing a mask. She also raised other safety concerns, including a previous armed robbery. Despite these concerns being flagged in occupational health reports and during meetings, the employer did not investigate them before deciding to dismiss on capability grounds.
What the losing side could have done differently
Marks and Spencer could have avoided this outcome by conducting a proper investigation into the claimant's safety concerns. Instead, they focused solely on the medical evidence that she was unfit for work with no foreseeable return. The tribunal noted that the employer failed to consider whether addressing the safety issues might have facilitated a return to work. A more thorough approach would have involved investigating the incidents, consulting with the claimant about possible adjustments, and considering whether a phased return or other support could have been offered.
Why the result matters for similar claims
This decision reinforces that capability dismissals must be based on a fair process that considers all relevant factors, including the reasons for the employee's ill health. Employers cannot simply rely on occupational health reports that say an employee is unfit for work; they must also explore whether the underlying causes can be addressed. The 25% Polkey reduction shows that even when the process is flawed, the tribunal may reduce compensation if it thinks dismissal was still likely. For employees, this case underscores the importance of raising safety concerns and ensuring they are documented, as this can form the basis of an unfair dismissal claim.
