Constructive Dismissal UK - Employment Rights, Examples and How to Claim in 2026

Understand constructive dismissal in the UK, including what qualifies, examples of employer misconduct, employee rights, resignation procedures, employment tribunal claims and compensation.

Constructive dismissal occurs when an employee resigns because their employer has committed a serious breach of their employment contract, making continued employment untenable.

Unlike ordinary dismissal, where an employer directly terminates someone's employment, constructive dismissal involves the employee leaving because of the employer's conduct.

Examples may include serious bullying, harassment, unlawful changes to contractual terms, persistent non-payment of wages or a fundamental breakdown of trust and confidence.

However, resigning because a job has become unpleasant or stressful does not automatically establish constructive dismissal. The employee must demonstrate that the employer committed a sufficiently serious contractual breach and that the resignation was a response to that breach.

Constructive dismissal claims can be legally complex, particularly where employees must establish eligibility for an unfair dismissal claim or show that the employer's actions justified resignation.

For employees, employers and businesses operating across London and the wider UK, understanding constructive dismissal is important for managing workplace disputes, employment contracts and financial obligations.

What Is Constructive Dismissal?

Constructive dismissal is a legal concept that arises when an employee terminates their employment contract in response to a fundamental breach by their employer.

In Great Britain, the statutory framework includes section 95(1)(c) of the Employment Rights Act 1996.

The employee must generally establish that:

1. The employer committed a fundamental breach of the employment contract.

2. The employee resigned in response to that breach.

3. The employee did not wait so long or act in a way that amounted to accepting the breach.

A fundamental breach is a sufficiently serious violation of the employment contract to justify termination by the employee.

The breach may involve an express contractual term or an implied term, such as the employer's duty not to destroy or seriously damage mutual trust and confidence without reasonable and proper cause.

Constructive dismissal is not automatically the same as unfair dismissal. A successful unfair constructive dismissal claim normally requires the employee to meet the applicable statutory conditions.

What Counts as Constructive Dismissal?

Constructive dismissal can arise from a single serious incident or a series of incidents that collectively amount to a fundamental breach of contract.

The employer's conduct must be sufficiently serious to justify the employee treating the contract as terminated.

Common Examples of Constructive Dismissal

Each case depends on its particular facts.

An employee must generally establish that the employer's conduct amounted to a fundamental contractual breach and caused the resignation.

Constructive Dismissal Due to Bullying

Workplace bullying may support a constructive dismissal claim where the conduct is sufficiently serious and the employer fails to address it appropriately.

Examples may include persistent humiliation, intimidation, unreasonable criticism or deliberately undermining an employee's professional responsibilities.

Not every disagreement with a manager constitutes bullying or constructive dismissal.

The seriousness of the conduct, the employer's response and the available evidence are important.

Where bullying is related to a protected characteristic, a separate discrimination claim may also arise.

Constructive Dismissal Due to Stress

Work-related stress does not automatically establish constructive dismissal.

However, serious employer conduct that causes or worsens workplace stress may be relevant.

For example, an employer might repeatedly ignore substantial concerns about unsafe workloads or subject an employee to sustained unreasonable treatment.

A claim depends on proving a fundamental breach of contract, not simply demonstrating that the employee experienced stress.

Medical records and correspondence may help establish the surrounding circumstances.

Constructive Dismissal Due to a Pay Cut

An employer who imposes a substantial reduction in contractual salary without agreement or lawful authority may commit a fundamental breach.

For example, reducing an employee's salary by 25% without a contractual basis could potentially justify a resignation and claim.

However, the outcome depends on the employment contract, consultation process and other circumstances.

Employees should obtain advice before resigning in response to a pay dispute.

Constructive Dismissal Due to Demotion

An unjustified demotion may amount to constructive dismissal.

This may occur where an employer significantly reduces an employee's responsibilities, status or remuneration without contractual authority.

However, a change in job title or duties is not automatically a fundamental breach.

The tribunal considers the substance and seriousness of the change.

Constructive Dismissal After Raising a Grievance

Employees may raise formal grievances about bullying, discrimination, contractual breaches or workplace treatment.

If an employer refuses to investigate a serious complaint or responds in a way that fundamentally damages trust and confidence, this may support a constructive dismissal claim.

However, an employee does not automatically establish constructive dismissal simply because a grievance was rejected.

The employer's overall conduct must meet the relevant legal threshold.

Constructive Dismissal vs Unfair Dismissal

Constructive dismissal and ordinary unfair dismissal are related but distinct.

A constructive dismissal may be legally established without necessarily resulting in a successful unfair dismissal claim.

How Long Must You Work to Claim Constructive Dismissal?

As of October 2026, an employee normally needs two years of continuous employment to bring an ordinary unfair constructive dismissal claim in Great Britain.

However, some claims do not require two years' service.

These may include claims connected with automatically unfair dismissal grounds, such as certain whistleblowing, health and safety or statutory rights situations.

Employees may also have separate discrimination or contractual claims, depending on the circumstances.

Employment Rights Changes in 2027

Under the Employment Rights Act 2025 reforms, the qualifying period for ordinary unfair dismissal is scheduled to reduce from two years to six months from 1 January 2027.

The changes are also intended to remove the statutory cap on compensatory awards for unfair dismissal.

The applicable rules depend on when employment ends and when the relevant provisions take effect.

Can You Claim Constructive Dismissal Without Two Years' Service?

Yes, in certain circumstances.

Employees may have protection where the resignation is connected to a reason that would make dismissal automatically unfair.

Examples can include protected whistleblowing, certain health and safety activities, pregnancy or maternity-related rights, and asserting specified statutory employment rights.

Separate claims for unlawful discrimination or unpaid contractual entitlements may also be available.

The legal requirements differ between claims, so employees should not assume that every constructive dismissal case requires the same length of service.

How to Prove Constructive Dismissal

Constructive dismissal claims require evidence.

Employees should be able to demonstrate the employer's conduct, the seriousness of the breach and the connection between that conduct and their resignation.

Useful evidence may include:

• Employment contracts and written policies.

• Emails and workplace correspondence.

• Payslips and payment records.

• Formal grievances and employer responses.

• Notes of relevant meetings.

• Witness statements.

• Records of changes to duties or working hours.

• Relevant medical evidence.

• The resignation letter.

Evidence should be obtained and retained lawfully, with appropriate regard for confidentiality and data protection obligations.

Should You Resign Before Making a Constructive Dismissal Claim?

A constructive dismissal claim normally arises after an employee resigns in response to the employer's fundamental breach.

However, resigning is a significant decision and should not be rushed.

Employees should consider obtaining independent legal advice before leaving employment.

Remaining at work for too long after a serious breach may allow the employer to argue that the employee accepted the situation.

On the other hand, leaving without a proper assessment of the circumstances may weaken a potential claim or create financial difficulties.

The appropriate course of action depends on the individual case.

Do You Have to Raise a Grievance First?

There is not always a strict legal requirement to complete a grievance procedure before resigning.

However, attempting to resolve the issue internally may be relevant.

An employee may initially raise concerns informally or submit a formal grievance.

Following an appropriate procedure can help document the employer's response.

A tribunal may also consider whether the parties complied with the relevant Acas Code of Practice when determining certain compensation adjustments.

Constructive Dismissal Resignation Letter

An employee who decides to resign because of an alleged fundamental breach should generally explain the reasons clearly.

The letter should identify the relevant conduct and state that the resignation is a response to the employer's actions.

It should remain factual and professional.

The employee should also consider whether to work their notice period or resign immediately.

A serious breach may justify resignation without notice in some circumstances, but legal advice is advisable because the consequences depend on the facts.

Can You Claim Constructive Dismissal While Working Your Notice?

Potentially.

Working a notice period does not automatically defeat a constructive dismissal claim.

However, the employer may argue that the employee accepted the breach by continuing to work.

The length of the notice period, the employee's conduct and the circumstances surrounding the resignation can all be relevant.

Employees should seek advice about the risks before deciding how to proceed.

How to Make a Constructive Dismissal Claim

An employee considering a constructive dismissal claim should assess the circumstances and obtain advice before starting tribunal proceedings.

The usual process involves:

1. Reviewing the employment contract and the alleged breach.

2. Gathering relevant evidence.

3. Considering internal grievance procedures.

4. Obtaining advice from Acas, a trade union or an employment solicitor.

5. Resigning in response to the breach where appropriate.

6. Notifying Acas within the applicable time limit.

7. Participating in early conciliation where appropriate.

8. Submitting an employment tribunal claim if the dispute remains unresolved.

A tribunal will consider whether the legal requirements for constructive dismissal and any associated claim have been satisfied.

Constructive Dismissal Time Limits in 2026

Employment tribunal time limits changed on 1 October 2026.

The applicable deadline depends on when the relevant event occurred.

For unfair dismissal claims, the time limit generally runs from the effective date employment ended.

Acas early conciliation can pause the time limit where notification is made in time.

Internal grievances do not automatically extend tribunal deadlines.

Different rules may apply to particular claims, including some contractual claims in Scotland.

Employees should check their exact deadline promptly.

What Is Acas Early Conciliation?

Acas early conciliation is a process intended to help employees and employers resolve workplace disputes without a full employment tribunal hearing.

The conciliator communicates with both parties and explores whether an agreement is possible.

Participation in settlement discussions does not guarantee that the dispute will be resolved.

If early conciliation does not produce an agreement, the employee may proceed with a tribunal claim, subject to the relevant requirements and deadlines.

How Much Compensation Can You Get for Constructive Dismissal?

Compensation depends on the type of claim, the employee's losses and the applicable statutory rules.

In an ordinary unfair constructive dismissal case, an award may include a basic award and a compensatory award.

The basic award is calculated using statutory rules involving age, length of service and qualifying weekly pay.

The compensatory award generally considers financial losses attributable to the unfair dismissal, subject to the applicable limits and adjustments.

Potential losses may include:

• Lost earnings.

• Lost employment benefits.

• Pension-related losses.

• Reasonable job-search expenses.

• Other qualifying financial losses.

Compensation is not automatic, and employees are generally expected to take reasonable steps to reduce their losses.

Separate discrimination claims may involve different remedies.

Can You Receive Compensation for Stress?

Compensation for emotional distress is not normally available merely because an ordinary unfair dismissal was upsetting.

However, a separate successful discrimination claim may permit compensation for injury to feelings.

In some circumstances, other legal claims may also be relevant.

Employees should distinguish between compensation for financial loss and compensation for non-financial harm.

Can You Claim Constructive Dismissal and Discrimination?

Yes, potentially.

An employee may bring a constructive dismissal claim alongside a discrimination claim where the employer's conduct also breaches the Equality Act 2010.

For example, an employee who resigns because of serious discriminatory harassment may have more than one legal basis for a claim.

The eligibility requirements, remedies and time limits must be considered separately.

Can You Claim Constructive Dismissal During Probation?

Potentially, although an ordinary unfair dismissal claim usually requires the applicable minimum qualifying service.

Employees on probation may still have rights relating to discrimination, automatically unfair dismissal, wages and contractual obligations.

The existence of a probationary period does not remove all statutory employment protections.
