High-Value Wrongful Dismissal in the UK: How Senior Executives Win (or Lose) Six-Figure Claims in the High Court

Introduction: Why the Stakes Are So High

For senior executives, bankers, and directors, a dismissal isn’t just a career setback—it’s a financial crossroads. The difference between “unfair” and “wrongful” dismissal is not just legal jargon; it’s the difference between walking away with a statutory cap of £115,115 or fighting for a payout that can easily exceed £250,000, £500,000, or even £2 million. The Employment Tribunal is not where the real money is won. For those with long notice periods, lucrative bonuses, and share options, the High Court is the only arena that matters.

Recent figures:

• In 2023, the average High Court wrongful dismissal claim for FTSE 250 executives was £420,000.

• The largest reported settlement in 2024 exceeded £3.1 million, including lost LTIPs and deferred bonuses.

• Legal costs for both sides routinely top £100,000–£250,000, making evidence and strategy absolutely critical.

What Most Executives Don’t Know (But Should)

Many senior professionals are surprised by how quickly the financial landscape shifts after dismissal. The most common misconceptions can cost you hundreds of thousands of pounds if not addressed early.

• The Tribunal Cap Is Irrelevant:
  The statutory cap (£115,115) only applies to unfair dismissal. If your contract entitles you to 12 months’ notice, a £200,000 bonus, and £300,000 in share options, your claim could be worth £500,000+—but only in the High Court. The Tribunal simply cannot award what your contract promises.

  
  

• Gross Misconduct Is “All or Nothing”:
  If your employer alleges gross misconduct, you lose everything—notice pay, bonus, shares. The High Court doesn’t care if the investigation was “reasonable”; it only cares if you actually did what you’re accused of. This means the factual evidence is king.

  
  

• Mitigation Is Make-or-Break:
  You must prove you tried to find a new job. A weak mitigation log can slash your damages by 50% or more. Courts expect to see a detailed, timestamped record of every job search activity.

  
  

• Bonus Battles Are Complex:
  Many executives don’t realise that being “under notice” on the bonus payment date can mean losing out on six-figure sums. Employers sometimes time dismissals to avoid paying bonuses, and proving this can be the difference between winning and losing.

Key Contentious Points

1. “Cause” vs. Contract: The Gross Misconduct Battle

Employers often allege gross misconduct to avoid paying notice and bonuses. The High Court will scrutinise:

• Was there a genuine repudiatory breach?

• Did the executive actually commit the alleged act?

• Was the process fair, or was the dismissal engineered to save costs?

Case Example:
In 2024, a City banker accused of “insubordination” won £650,000 after the court found no actual breach—despite a lengthy internal investigation. The judge focused on the facts, not the employer’s process.

Key Evidence:

• Internal emails and board minutes.

• Witness statements from colleagues.

• The employment contract and disciplinary policy.

2. The Bonus Battle: Lavarack v Woods of Colchester

Executives often lose bonuses if not “employed and not under notice” on the payment date. The fight is over:

• Would the bonus have been paid but for the wrongful dismissal?

• Forensic accounting is key—historical bonus data, LTIP vesting schedules, and board minutes can make or break the claim.

Key Evidence:

• Bonus plan documents.

• Historical bonus payments and LTIP schedules.

• Emails showing the timing and rationale for dismissal.

3. Mitigation of Loss

You must show you made reasonable efforts to find new work. Courts expect:

• A detailed log of every job application, headhunter call, and interview.

• Evidence of salary offers and rejections.

• Proof that you didn’t “sit on the beach” waiting for a payout.

Case Example:
In Hendy Group Ltd v Kennedy [2024] EAT 106, the claimant’s damages were preserved because he kept a meticulous job search record, including emails, interview confirmations, and rejection letters.

Typical Outcomes and Figures

Key Takeaways:

• Most cases settle before trial, often with confidentiality clauses.

• Damages are calculated to put the executive in the position they would have been in had the contract been performed.

• Legal costs are substantial, so early settlement is often attractive.

Evidence That Wins (The “Product” Angle)

Winning a high-value wrongful dismissal claim is all about the evidence. The best-prepared executives have:

• Forensic Accounting:

  • Detailed spreadsheets showing lost salary, bonuses, LTIPs, and benefits.

  • Historical data to prove what you would have earned.

  • Expert reports to quantify loss.

    
    

• Mitigation Logs:

  • Timestamped records of every job search activity.

  • Copies of applications, interview invitations, and rejection letters.

  • Notes from headhunter calls and networking meetings.

    
    

• The “Smoking Gun” Email:

  • Internal emails showing the dismissal was engineered to save costs, not for genuine misconduct.

  • Board minutes discussing the financial impact of termination.

  • Evidence that the timing of dismissal was linked to bonus payment dates.

    
    

• Contractual Documents:

  • The full employment contract, including notice period, bonus plan, and LTIP terms.

  • Any amendments, side letters, or settlement agreements.

Actionable Steps: What to Do in the First 7 Days

If you’ve just been dismissed, the first week is critical. Here’s what you should do:

• Preserve All Evidence:

  • Save emails, contracts, bonus plans, and any correspondence about your dismissal.

  • Back up your work calendar and any relevant files.

    
    

• Start Your Mitigation Log:

  • Record every job search activity from day one.

  • Include dates, times, and outcomes.

    
    

• Request Written Reasons:

  • Ask your employer for a written explanation of the dismissal.

  • This can be vital if the reason changes later.

    
    

• Calculate Your Losses:

  • List salary, bonus, shares, benefits, and pension contributions.

  • Use historical data to estimate what you would have earned.

    
    

• Consider Settlement:

  • Most cases settle—know your numbers and be ready to negotiate.

  • Don’t rush to accept the first offer; understand your leverage.

    
    

• Seek References:

  • Request a reference before things get adversarial.

  • A positive reference can help with mitigation and future job searches.

Final Thoughts: Why Preparation Pays

High-value wrongful dismissal claims are won or lost on preparation. The executives who succeed are those who:

• Act quickly to preserve evidence.

• Build a meticulous mitigation log.

• Understand the true value of their claim, including bonuses and share options.

• Are ready to negotiate but prepared to fight if necessary.

If you’re facing dismissal, don’t underestimate the importance of evidence and timing. The financial stakes are enormous, and the right strategy can make all the difference.
