International Sports Co Ltd v Thomson

Repeated short-term absences can justify dismissal if your employer follows a fair process.

The ruling

“Dismissal for persistent short-term absence upheld as fair because the employer followed a proper attendance process.”

Persistent short-term absences can justify dismissal even where each absence was caused by genuine illness, but only if your employer followed a fair procedure including warnings and a genuine opportunity to improve.

  • Make sure your employer clearly communicated the attendance level expected and the consequences of continued absence before any warning or dismissal.
  • If an underlying health condition is contributing to your absences, tell your employer and ask whether adjustments can be made; this changes the legal analysis.
  • If warnings skipped a step, or your dismissal came without one, get advice quickly. The claim window is short.

The situation

An employee built up a poor attendance record from a series of unrelated short-term illnesses over time. The employer ran an attendance procedure that included informal discussion, warnings and review meetings, and eventually dismissed the employee. The question for the tribunal was whether dismissal for a pattern of absence caused by genuine, unconnected illnesses could ever be fair.

What the tribunal found

The Employment Appeal Tribunal held the dismissal was fair. Persistent, intermittent absence can justify dismissal even where every individual absence was caused by genuine illness, provided the employer followed a fair process. In practice that means the employer made the employee aware their attendance was a problem, checked whether there was a medical explanation for the pattern, warned them clearly that continued absence could lead to dismissal, and gave them a real chance to improve or explain.

The tribunal also drew an important distinction. Where absences come from a string of unconnected minor illnesses rather than one ongoing condition, a medical prognosis is often impossible to get, because there is no single condition for a doctor to give one on. In that situation, the employer can manage the problem through the attendance procedure rather than the ill-health capability process used for long-term sickness.
