How to enforce rights after constructive dismissal in England and Wales, including legal requirements, resignation rules, ACAS Early Conciliation, employment tribunal claims, compensation entitlement, employer defences, and key time limits under the Employment Rights Act 1996.

Constructive dismissal occurs where an employee resigns in response to a fundamental breach of contract by their employer. The resignation is treated in law as a dismissal because the employer's conduct has effectively forced the employee to leave.
The concept is primarily derived from common law and is closely linked to the implied term of mutual trust and confidence within employment contracts. Claims are typically brought under the Employment Rights Act 1996 as claims for unfair dismissal, provided the employee meets qualifying service requirements.
Enforcing rights after constructive dismissal involves a structured legal process, including internal procedures, ACAS Early Conciliation, and potentially an employment tribunal claim for compensation.
What Counts as Constructive Dismissal
Constructive dismissal arises where:
- The employer commits a fundamental breach of contract, and
- The employee resigns in response to that breach, and
- The employee does not affirm the contract by continuing employment for too long after the breach
Common examples include:
- Non-payment or significant reduction of wages
- Serious bullying or harassment
- Unilateral changes to working conditions or duties
- Breach of trust and confidence
- Failure to address grievances or unsafe working conditions
- Discriminatory treatment affecting employment terms
The leading legal principle is that the employer's conduct must be sufficiently serious to go to the root of the contract.
Legal Framework for Constructive Dismissal Claims
Constructive dismissal claims are generally brought under:
- Employment Rights Act 1996, section 95(1)(c)
- Unfair dismissal provisions (sections 94–98 ERA 1996)
- Common law principles of repudiatory breach of contract
- Equality Act 2010 (where discrimination is involved)
Employment tribunals assess:
- Whether a fundamental breach occurred
- Whether the employee resigned because of it
- Whether the employee acted promptly in resigning
- Whether the employer's conduct justified dismissal
Step-by-Step: How to Enforce Rights After Constructive Dismissal
1. Identify and Document the Breach
The first step is to clearly establish the employer's conduct that triggered resignation.
Evidence may include:
- Emails or written instructions
- HR correspondence
- Witness statements
- Pay records or contractual documents
- Notes of incidents or meetings
It is important to show that the breach was serious enough to undermine the employment relationship.
2. Resign in Response to the Breach
To preserve a constructive dismissal claim:
- Resignation must be clearly linked to the employer's breach
- The reason should be stated in writing
- The resignation should not be significantly delayed after the breach
A resignation letter typically sets out:
- The fundamental breach relied upon
- The reasons for resignation
- The date of termination
Continuing to work for an extended period after the breach may be interpreted as acceptance of the employer's conduct.
3. Check Eligibility for Unfair Dismissal Claim
Constructive dismissal is treated as a dismissal for legal purposes. To bring an unfair dismissal claim:
- Usually 2 years' continuous service is required
- Exceptions apply in cases involving discrimination, whistleblowing, or automatically unfair dismissal
If qualifying service is met, a claim can be made under unfair dismissal provisions.
4. Use ACAS Early Conciliation
Before submitting a tribunal claim, it is mandatory to notify ACAS and begin Early Conciliation.
This process:
- Allows for settlement discussions
- Temporarily pauses tribunal time limits
- Is required for most employment tribunal claims
If no resolution is reached, ACAS issues a certificate needed for tribunal proceedings.
5. Submit an Employment Tribunal Claim
A claim is made using the ET1 form and typically includes:
- Constructive unfair dismissal
- Related claims such as unpaid wages or discrimination
- Details of the employer's breach and resignation
The tribunal will assess whether the resignation amounted to dismissal in law and whether it was fair or unfair.
Compensation in Constructive Dismissal Cases
If the claim succeeds, compensation may include:
- Basic award (similar to redundancy calculation)
- Compensatory award (loss of earnings and benefits)
- Loss of future earnings in appropriate cases
- Pension losses
- In discrimination cases, injury to feelings awards under the Vento guidelines
Compensation is designed to put the employee in the position they would have been in had the dismissal not occurred.
Time Limits for Claims
Strict time limits apply:
- 3 months minus 1 day from the date of termination
Key points:
- ACAS Early Conciliation pauses the limitation period
- Internal grievance procedures do not extend time limits
- Late claims are rarely accepted unless exceptional circumstances apply
Common Employer Defences
Employers may argue:
- No fundamental breach occurred
- Employee resigned for unrelated reasons
- Employee delayed resignation, affirming the contract
- Conduct was reasonable or justified
- Procedural issues were addressed appropriately
Tribunals assess all evidence objectively to determine whether the breach was sufficiently serious.
Risks and Practical Considerations
1. Timing of Resignation
Delayed resignation can weaken a claim if it suggests acceptance of the breach.
2. Evidential Burden
The employee must prove both the breach and causal link to resignation.
3. Financial Risk
If a claim is unsuccessful, legal costs may arise in certain circumstances.
4. Relationship Breakdown
Resignation often ends employment permanently, limiting negotiation leverage.
Alternative Resolution Options
Before tribunal proceedings, parties may resolve disputes through:
- Internal grievance procedures
- Settlement agreements
- ACAS conciliation agreements
- Without prejudice negotiations
Settlement agreements typically include financial compensation in exchange for waiving legal claims.
Common Questions from our Readers
Can I claim constructive dismissal if I have not resigned?
No. Resignation is required for constructive dismissal, although internal complaints may precede it.
Do I need 2 years' service?
Usually yes for unfair dismissal claims, but not where discrimination or whistleblowing applies.
Can I still claim if I found another job?
Yes. Compensation may be adjusted based on mitigation of losses.
What if the employer disputes the breach?
The tribunal will evaluate evidence from both parties to determine whether a breach occurred.
Key Takeaways
Enforcing rights after constructive dismissal requires demonstrating a fundamental breach of contract, resigning in response to that breach, and pursuing legal remedies through ACAS Early Conciliation and the employment tribunal system.
Key points:
- Constructive dismissal requires a serious breach by the employer
- Resignation must be directly linked to the breach
- Most claims require 2 years' service unless exceptions apply
- ACAS Early Conciliation is mandatory before tribunal claims
- Compensation may include lost earnings and statutory awards
Understanding the legal structure and timing of actions is essential to effectively enforce rights following resignation due to employer conduct.
