Case details

Key facts

  • The claimant was employed as a teacher at Tameside College and went on sick leave on 10 October 2019.
  • She sent three emails to her manager in May, June, and August 2019 complaining about a colleague's behaviour.
  • The tribunal found these emails did not amount to protected disclosures under whistleblowing law.
  • The claimant had a diagnosis of anxiety with depression but failed to prove it had a substantial adverse effect on her day-to-day activities.
  • The respondent dismissed the claimant on capability grounds due to long-term sickness absence after 11 months.
  • The tribunal held the dismissal was fair and within the band of reasonable responses.

    Ms Berry and Ms Pearson met with claimant; claimant sought an 'exit strategy'.

  6. Occupational health appointment

    Occupational health practitioner found claimant temporarily unfit for work but capable of attending meetings.

  7. Grievance raised

  8. First sickness absence panel

    Panel met again; claimant did not attend. Decision made to dismiss on capability grounds.

  10. Dismissal confirmed

    Claimant received letter confirming dismissal due to incapability to perform work.

The outcome

The tribunal dismissed all claims. It found that the three emails sent by the teacher about a colleague's behaviour were not made in the public interest and therefore were not protected disclosures. The teacher failed to show that her anxiety and depression had a substantial adverse effect on her day-to-day activities, so she was not disabled under the Equality Act. The dismissal for capability due to long-term sickness was fair because the college followed a reasonable process, including obtaining occupational health advice and holding meetings over several months. No compensation was awarded.

Lessons & takeaways

  • To bring a whistleblowing claim, the disclosure must be made in the public interest – personal grievances about a colleague's behaviour are unlikely to qualify.
  • Proving a mental health condition is a disability requires medical evidence showing a substantial and long-term adverse effect on daily activities.
  • Employers can fairly dismiss for long-term sickness if they follow a proper process, including obtaining up-to-date medical advice and considering alternatives.
  • Length of absence is a key factor – 11 months of continuous sick leave can justify dismissal if recovery is uncertain.

What this case shows

A teacher at Tameside College went on sick leave in October 2019 and never returned. After 11 months, the college dismissed her on capability grounds. The teacher argued that her dismissal was unfair, that she had made protected disclosures about a colleague, and that she was disabled due to anxiety and depression. The tribunal rejected all of these arguments.

The case illustrates the high bar for whistleblowing claims. The teacher had sent three emails to her manager in 2019 complaining about a colleague's behaviour towards students. The tribunal found these were personal grievances, not disclosures made in the public interest. They did not meet the legal test for a protected disclosure.

Why the disability claim failed

To be protected under the Equality Act, a mental impairment must have a substantial and long-term adverse effect on normal day-to-day activities. The teacher provided a witness impact statement describing her symptoms, but the tribunal was not satisfied that the effect was substantial enough. The occupational health report noted she was temporarily unfit for work but capable of attending meetings. Without stronger medical evidence, the disability claim could not succeed.

The dismissal was fair

The college had followed a reasonable process. It held a welfare meeting at the teacher's home, obtained an occupational health report, and convened a sickness absence panel. The panel adjourned to seek an updated report, then reconvened and decided to dismiss. The tribunal noted that the teacher had not attended the panel meetings and had not provided any indication of when she might return. The decision to dismiss was within the band of reasonable responses.

What could have been done differently

For the teacher, stronger medical evidence of disability and clearer public interest disclosures might have changed the outcome. For employers, the case confirms that a structured capability process with medical input and reasonable delays can justify dismissal for long-term sickness, even when the employee has raised grievances.
