Whistleblowing and the short-service employee

Capeling v TFX Group Ltd

A recent Employment Appeal Tribunal decision, Capeling v TFX Group Ltd [2026] EAT 57, looks at first glance like good news for employers. In short, the employer won.

But it's also a cautionary tale. The employee had been in post for less than six months, but the case still took around three and a half years to resolve.

What happened?

Mrs Capeling was taken on as a National Sales Manager by TFX Group, a medical device manufacturer, in March 2022, on a six-month probationary period.

Shortly before that probation was due to end, she was dismissed with immediate effect and given a week’s pay in lieu of notice. The reason given was poor performance.

She claimed that she had been automatically unfairly dismissed for whistleblowing, and also claimed detriment on this ground. Whistleblowing protection is a day-one right, and compensation is uncapped.

She relied on three alleged disclosures about the business. The tribunal found she had not made the first disclosure at all, and that the second and third did not qualify for protection.

She appealed on one: a claim that the absence of written contracts with certain contractors was putting the health and safety of patients at risk, and that this was being concealed. In March 2026, the EAT dismissed her appeal.

Why did she lose?

For protection, a whistleblower must disclose actual information, not simply make a general allegation. They must also reasonably believe it shows something such as a health and safety risk in the public interest.

The tribunal found, and the EAT agreed, that Mrs Capeling had done no more than assert a risk, without the factual detail needed to amount to “information”.

It also found that, given her senior role, any belief that missing contracts endangered patients was not a reasonable one. The employer’s evidence that the contracts had no bearing on safety was accepted.

The real lesson: the win took three and a half years

The journey looked like this:

September 2022: dismissal
November 2022: tribunal claim lodged
March and November 2023: two preliminary hearings
2024: full tribunal hearing and judgment
March 2026: appeal heard and dismissed by the EAT

That is roughly three and a half years of litigation for a dismissal of what we often refer to as a “short-service” employee.

The process will have involved years of management time, legal cost, disruption and uncertainty.

An increasingly common situation

According to the Ministry of Justice’s employment tribunal statistics, whistleblowing, or public interest disclosure, claims more than doubled in the year to December 2025.

They increased by around 102%, from roughly 890 to about 1,800 in a single quarter, making them the fastest-growing type of tribunal claim.

Yet they remain notoriously hard to win. In one recent quarter, not one of the 519 whistleblowing claims decided at a full hearing succeeded.

So, most will ultimately fail, but that has not prevented claims from being brought. And even a failed claim can take years to resolve.

What can an employer do?

Don’t assume a probationer or “short-service” employee “can’t claim”. If they can point to a disclosure, they can bring a whistleblowing claim from their first day.
Take concerns seriously and record how you respond. Many of these claims turn on whether the employer investigated.
Evidence the genuine reason for any dismissal clearly and at the time. A well-documented performance or conduct reason is your strongest protection against an allegation of whistleblowing.
Be especially alert where concerns are raised shortly before an exit. This situation indicates a clear risk.
Take advice early. As Capeling shows, even an unfounded claim can run for years. Getting your response right at the start is the best way to manage the risk.

The headline result is reassuring. It's the timeline that is the warning. And tribunal timescales are only getting longer. The process will have involved years of management time, legal cost, disruption and uncertainty.
