Limitation Period for Constructive Dismissal Claims After Resignation

Constructive dismissal claims arise where an employee resigns in response to a fundamental breach of contract by the employer. Although the employee resigns voluntarily, the law treats the resignation as a dismissal for the purposes of an Employment Tribunal claim if the legal test is met.

Like unfair dismissal claims, constructive dismissal claims are subject to strict time limits. These deadlines are strictly enforced in England and Wales and are central to whether a claim can proceed at all.

The key issue is identifying when the limitation period begins after resignation, which depends on the effective date of termination (EDT).

What Is Constructive Dismissal in Legal Terms

Constructive dismissal occurs where:

• The employer commits a fundamental breach of contract, and
• The employee resigns in response to that breach, treating the contract as terminated

Common examples include:

• Serious breaches of trust and confidence
• Unlawful unilateral changes to pay or duties
• Persistent bullying or harassment
• Failure to address serious workplace grievances

Although the employee resigns, the law treats the situation as a dismissal for tribunal purposes if the legal test is satisfied.

When the Limitation Period Starts

The key rule: Effective Date of Termination (EDT)

For constructive dismissal claims, the limitation period starts on the effective date of termination (EDT).

In constructive dismissal cases, the EDT is usually:

• The date the employee resigns, if resignation is immediate, or
• The last day of the notice period, if notice is given and worked

This date is treated as the point at which employment legally ends.

Standard Time Limit

The limitation period is:

• 3 months minus 1 day from the EDT

This applies to:

• Constructive dismissal claims
• Associated unfair dismissal claims
• Most Employment Tribunal claims relating to termination

Example:

• Resignation date (EDT): 10 March
• Deadline to submit claim: 9 June (11:59pm)

Special Issue: Timing of Resignation in Constructive Dismissal

Constructive dismissal claims are unique because the EDT is directly linked to the resignation decision.

Key principle

The limitation period does not start when:

• The breach first occurred
• The employee first complained
• The internal grievance process concluded

It starts when:

• The employee resigns and ends the employment relationship

Continuing Breaches and the EDT

In some cases, employers commit ongoing breaches over time. This raises an important timing issue.

General approach

The limitation period usually starts when:

• The employee resigns in response to the final straw or last breach

Earlier incidents are relevant to the claim but do not normally change the EDT.

Practical effect

Even if misconduct occurred over months:

• The clock starts at resignation, not at the first act of misconduct

ACAS Early Conciliation and Constructive Dismissal Timing

Before bringing a tribunal claim, most claimants must notify ACAS and engage in early conciliation.

Effect on limitation period

• The limitation clock is paused when ACAS is notified (if still in time)
• The pause continues until an Early Conciliation Certificate is issued
• After the certificate, the clock resumes

Minimum time rule

After conciliation ends:

• The claimant usually has at least 1 month to submit the claim, even if the original deadline has nearly expired

Common Misunderstandings About the Start Date

1. Starting point is not the misconduct date

The limitation period does not start when:

• Bullying or breach first occurred
• Employer conduct became unreasonable
• Employee first experienced workplace problems

It starts at resignation (EDT).

2. Delay in resigning can affect timing but not restart limitation

Employees may delay resignation while:

• Raising grievances
• Seeking resolution
• Collecting evidence

However:

• The limitation period still begins at resignation, not at earlier stages

3. Notice periods matter

If the employee gives notice:

• The EDT is usually the final day of the notice period
• The limitation period starts at the end of that notice period

Extension Rules if the Deadline Is Missed

If a constructive dismissal claim is submitted late:

• The tribunal will normally refuse to hear it
• It can only proceed if it was not reasonably practicable to submit in time
• The claim must also be submitted promptly once it becomes possible

This is a strict test and is applied narrowly. Delay caused by uncertainty, grievance processes, or lack of legal advice is usually not sufficient.

Interaction With Other Claims

A constructive dismissal case may include multiple claims, such as:

• Unlawful deduction of wages
• Breach of contract
• Discrimination claims
• Holiday pay claims

Each may have:

• Different limitation rules
• Different start dates depending on the cause of action

Discrimination claims, for example, may use a “just and equitable” extension test, which is broader than unfair/constructive dismissal rules.

Practical Consequences of Missing the Limitation Period

If the claim is out of time:

• The Employment Tribunal will usually reject the claim
• The merits of the resignation and breach will not be considered
• Compensation for loss of employment may be unavailable through the tribunal

This makes correct calculation of the EDT and deadline critical.

Key Summary

• Constructive dismissal claims must be brought within 3 months minus 1 day
• The limitation period starts on the effective date of termination (EDT)
• In most cases, the EDT is the date of resignation or end of notice period
• The clock does not start when misconduct begins or when grievances are raised
• ACAS early conciliation pauses the limitation period if started in time
• Late claims are only accepted if it was not reasonably practicable to file on time
• Tribunals apply strict rules and extensions are rare
