Understanding Constructive Dismissal: When Resignation Isn't the End

You didn't want to leave your job, but staying became impossible. Perhaps your employer breached your contract, created an unbearable working environment, or forced changes you couldn't accept. You resigned - but that doesn't mean you have no legal recourse.

If you resigned because your employer's conduct made your position untenable, you may have a claim for constructive dismissal. This guide explains what constructive dismissal is, whether you have a claim, and how to protect your rights.

What is Constructive Dismissal?

Constructive dismissal (also called constructive unfair dismissal) occurs when you're forced to resign because your employer has:

• Seriously breached your employment contract, AND
• The breach was so serious it destroyed trust and confidence, AND
• You resigned in response to that breach

The legal test comes from the landmark case Western Excavating (ECC) Ltd v Sharp [1978], which established two approaches:

Contract Test: Your employer breached a fundamental term of your contract
Reasonableness Test: Your employer behaved so unreasonably that you couldn't be expected to continue

Most successful claims use the "fundamental breach of the implied duty of trust and confidence."

The Implied Duty of Trust and Confidence

Every employment contract includes an implied term that your employer won't, without reasonable cause, conduct themselves in a way calculated or likely to destroy or seriously damage the relationship of trust and confidence between employer and employee.

This was established in Malik v BCCI [1997] and is the foundation of most constructive dismissal claims.

Common Scenarios of Constructive Dismissal

1. Significant Reduction in Pay or Benefits

Example: Your employer unilaterally cuts your salary by 20% or removes your company car without agreement.

Why it's a breach: Pay is a fundamental contractual term. Significant reductions without consent breach your contract.

What to do: Reject the change in writing, state you're working under protest, and seek immediate legal advice.

2. Demotion or Removal of Responsibilities

Example: You're moved to a junior role, stripped of management responsibilities, or given meaningless tasks far below your level.

Why it's a breach: Your job title and responsibilities are contractual. Significant changes without agreement may breach trust and confidence.

What to do: Raise a formal grievance immediately, documenting how the changes breach your contract and affect your professional standing.

3. Bullying, Harassment, or Hostile Environment

Example: Your manager subjects you to aggressive behaviour, public humiliation, or creates an intimidating work environment. You've raised complaints but nothing changes.

Why it's a breach: Failing to protect you from bullying or harassment breaches the duty to provide a safe working environment and destroys trust.

What to do: Document every incident, raise formal grievances, and keep evidence of inadequate employer response.

4. Forced Relocation

Example: Your employer demands you relocate to a different city without consultation or contractual mobility clause.

Why it's a breach: Your workplace location is usually a contractual term. Unilateral changes may be a fundamental breach.

What to do: Check your contract for mobility clauses, refuse the change in writing, and propose alternatives.

5. Failure to Address Grievances

Example: You've raised serious concerns about working conditions, discrimination, or safety issues, but your employer ignores them or fails to investigate properly.

Why it's a breach: Failing to address legitimate grievances breaches the implied duty of trust and confidence.

What to do: Follow up in writing, escalate to senior management, and document the inadequate response.

6. Impossible Working Conditions

Example: Your employer sets unrealistic targets, refuses reasonable adjustments, or creates conditions that make your job impossible to perform.

Why it's a breach: Making your role impossible to perform constructively dismisses you.

What to do: Document the unreasonable demands, their impact, and request written clarification of expectations.

The Legal Test: Three Critical Elements

For a successful constructive dismissal claim, you must prove:

1. Fundamental Breach by Your Employer

The breach must be serious enough to justify resignation. Minor issues or single incidents rarely suffice (unless extremely serious).

Examples that may be fundamental:

• Material pay reduction
• Demotion without consent
• Sustained bullying with no action
• Serious health and safety failures
• Breach of confidentiality or data protection affecting you

2. You Didn't Affirm the Breach

You must resign in response to the breach, not delay so long that you're seen as accepting the new situation.

Critical timing:

• Don't wait too long after the breach (weeks, not months)
• Don't continue working normally as if nothing happened
• Resign explicitly because of the breach

3. You Resigned Because of the Breach

Your resignation must be in response to the breach, not for other reasons like finding a better job.

What tribunals look for:

• Clear link between breach and resignation
• Resignation letter mentioning the breach
• No other reason for leaving

The "Last Straw" Doctrine

Sometimes, no single incident is serious enough alone, but a series of incidents culminates in a final act that breaks trust and confidence.

The leading case is London Borough of Waltham Forest v Omilaju [2005], which established:

✓ The final straw needn't be major, but must contribute to the breach
✓ Previous incidents can be considered together
✓ The final straw must be part of the same course of conduct
✗ The final straw can't be trivial or unrelated

Example: Months of unreasonable criticism, followed by being excluded from an important meeting - the exclusion may be the final straw.

Critical Mistakes That Weaken Your Claim

❌ Resigning Without Raising a Grievance

Why it matters: Tribunals expect you to give your employer a chance to fix the problem. Resigning without a grievance suggests you didn't think the issue was serious.

Exception: If the breach is so serious that no grievance could fix it (e.g., serious assault), immediate resignation may be justified.

❌ Waiting Too Long

Why it matters: Delaying suggests you've accepted the breach or you're resigning for other reasons.

Guidance: Days or weeks are usually acceptable; months are problematic.

❌ Accepting the Breach

Why it matters: Continuing to work normally without protest suggests you've accepted the new situation.

How to avoid: Work "under protest," put objections in writing, and act promptly.

❌ Vague Resignation Letter

Why it matters: Your resignation letter is key evidence. If it doesn't mention the employer's conduct, tribunals may doubt your claim.

What to include: Clear statement that you're resigning due to employer's breach of contract, specific examples, and that you consider yourself constructively dismissed.

How to Resign for Constructive Dismissal

Your Resignation Letter Should:

1. State clearly you're resigning due to employer breach
"I am resigning because of your fundamental breach of my employment contract and the implied term of trust and confidence."

2. Specify the breaches
Detail the employer's conduct that forced your resignation with dates and examples.

3. Mention previous attempts to resolve
Reference grievances raised and the inadequate response.

4. State you consider yourself constructively dismissed
"I consider myself to have been constructively dismissed and reserve my rights to pursue all legal remedies."

5. Confirm your notice period
State whether you'll work notice or treat yourself as dismissed with immediate effect.

Sample Resignation Letter

[Your Address]
[Date]

[Employer's Name and Address]

Dear [Manager's Name],

Resignation - Constructive Dismissal

I am writing to resign from my position as [Job Title] with immediate effect. I consider myself to have been constructively dismissed due to your fundamental breach of my employment contract and the implied term of trust and confidence.

Despite my attempts to resolve these issues, the following breaches have made my position untenable:

[Specific breach 1 with dates and details]
[Specific breach 2 with dates and details]
[Specific breach 3 with dates and details]

I raised these concerns formally through my grievance dated [date], which you failed to address adequately. Your response dated [date] did not resolve the fundamental issues, and the situation has continued to deteriorate.

I have been left with no alternative but to resign. I consider this a constructive dismissal and reserve all my legal rights.

I will not be working my notice period as your conduct has made it impossible for me to continue in my role. I consider you to have waived my obligation to work notice through your breaches.

Please confirm receipt of this letter and provide my P45 and final pay, including accrued holiday pay, within the statutory timeframe.

Yours sincerely,
[Your Signature]
[Your Name]
