Breach of Employment Contract

A breach of employment contract happens when an employee or an employer fails to honour a term of the contract of employment. For employees, it might mean unpaid wages, a sudden pay cut, or dismissal without the notice owed. For employers, it could mean a worker walking out mid-shift, refusing to work their notice, or joining a competitor in breach of a restrictive covenant. Whatever side you are on, understanding what counts as a breach of employment contract under UK law — and what you can do about it — can save you considerable money, time and stress.

This guide explains how UK courts and employment tribunals recognise a breach, the difference between minor breaches and repudiatory breaches, when a breach allows an employee to resign and claim constructive dismissal, the remedies available (including damages and tribunal claims), and the practical steps both sides should take. This article focuses specifically on breach. For the background on how employment contracts work, see our complete guide to contracts of employment.

What Is a Breach of Employment Contract?

A breach of employment contract is any failure to perform what the contract requires — sometimes called a breach of employment agreement or a breach of work contract. The contract may be written, partly written and partly verbal, or built from terms implied by law. To decide whether a breach has occurred, you first have to identify the term that was broken.

Employment contracts contain two kinds of terms. Express terms are the ones written down or agreed verbally: pay, hours, place of work, notice periods, holiday entitlement and restrictive covenants. Implied terms are read into the contract by law or custom, even if nobody wrote them down. The most important implied term in UK employment law is the duty of mutual trust and confidence: neither side should, without reasonable and proper cause, behave in a way likely to destroy or seriously damage the working relationship. Others include the employer’s duty to provide a safe system of work and the employee’s duties of fidelity and obedience.

Not every disappointment at work is a breach of employment contract. A difficult manager or a poor performer has not necessarily broken any contractual term. A breach needs an identifiable term and a failure to comply with it. That distinction matters, because only a genuine breach unlocks the remedies described below.

What Counts as a Breach? Common Examples

Breaches range from the obvious, such as unpaid wages, to the subtle, such as a slow erosion of trust through repeated unreasonable behaviour. The examples below are divided by who commits the breach.

Breach of Employment Contract by Employer

A breach of employment contract by employer is the more common complaint, and it often involves money or fundamental changes to the job. Typical examples include:

• Failing to pay wages on time, or at all — including unlawful deductions from pay
• Cutting pay, hours or benefits without the employee’s agreement
• Changing duties, shift patterns or place of work unilaterally
• Failing to pay contractual notice pay, accrued holiday pay or contractual sick pay
• Demoting an employee or suspending them without pay where the contract does not allow it
• Bullying, harassment or victimisation by management — a breach of the implied term of mutual trust and confidence
• Failing to provide a safe working environment

Many of these overlap with statutory employment rights in the UK, which exist alongside the contract. An unlawful pay cut, for example, can be both a breach of employment contract and an unlawful deduction from wages under the Employment Rights Act 1996.

Breach of Employment Contract by Employee

A breach of employment contract by employee often involves:

• Resigning and leaving without working the contractual notice period
• Persistent unauthorised absence or refusal to carry out lawful, reasonable instructions
• Disclosing confidential information or trade secrets
• Joining a competitor or poaching clients in breach of post-termination restrictive covenants
• Serious misconduct such as theft, fraud or violence at work

Employers sometimes assume they can withhold a departing employee’s final pay as punishment for leaving early. That is risky: withholding wages that are contractually due is itself a breach of employment contract by the employer, and can turn a strong position into a weak one.

Repudiatory Breach: When a Breach Is Serious Enough to End the Contract

UK law distinguishes between minor breaches, which give rise to a claim for damages but leave the contract alive, and repudiatory breaches — breaches so serious they show the breaching party no longer intends to be bound. A repudiatory breach of employment contract might be a substantial unilateral pay cut, a demotion imposed without agreement, or a campaign of bullying that destroys trust and confidence.

The label matters because a repudiatory breach gives the innocent party a choice: accept the repudiation and treat the contract as at an end, or affirm it and carry on. Accepting a repudiatory breach is what allows an employee to resign and claim constructive dismissal, or an employer to dismiss summarily for gross misconduct.

There is a catch: you must act promptly and consistently. An employee who complains about a serious breach but then works on for months without protest may be taken to have affirmed the contract, losing the right to treat it as ended. The safer course is to state in writing that you consider the conduct a breach, that you are working under protest, and that you reserve your rights.

Constructive Dismissal and Breach of Contract

Constructive dismissal is the bridge between breach of contract and unfair dismissal law. It occurs where the employer’s conduct amounts to a fundamental breach of contract, the employee resigns in response to that breach, and the employee does not delay so long as to be deemed to have accepted it. The classic formulation comes from Western Excavating v Sharp, and it remains the test employment tribunals apply.

The breach need not be a single dramatic event. Tribunals recognise the “last straw” doctrine: a series of smaller breaches can cumulatively destroy trust and confidence, with a final act — even a relatively minor one — tipping the balance. That final straw need not itself be a breach, but the overall course of conduct must be.

Employees considering this route should understand two things. First, resignation is a leap: if the tribunal finds no fundamental breach, you have simply resigned and may struggle to claim anything. Second, a constructive dismissal claim is usually paired with a constructive unfair dismissal claim, which has its own eligibility rules on length of service. Because the stakes are high, take advice before resigning — our guide on when to hire an employment contract lawyer explains what that first conversation should cover.

Breach of Contract Claims in the Employment Tribunal

A breach of contract employment tribunal claim is available where the claim arises or is outstanding on the termination of employment — the classic example is unpaid notice pay or wages owed at the end of the job. The essentials:

• The £25,000 cap. Employment tribunals can award no more than £25,000 for breach of contract. Larger claims must go to the county court or High Court.
• Short time limits. Tribunal claims must generally start within three months less one day of the effective date of termination, and Acas early conciliation must usually be attempted first. Court claims allow up to six years, but that is rarely a reason to delay.
• Contract law only. In these claims tribunals apply ordinary contract principles — there is no compensation for hurt feelings.

Choosing the right forum matters. If you are owed £40,000 in notice pay, issuing in the tribunal means abandoning everything above £25,000. An adviser can help weigh the tribunal’s speed and lower cost against the court’s higher ceiling.

Remedies and Penalties for Breach of Employment Contract

The starting point for any breach of employment contract is damages: money to put the innocent party in the position they would have been in had the contract been performed. For an employee, that usually means unpaid wages, notice pay, lost benefits and sometimes lost commission or bonuses. For an employer, it might mean the cost of cover staff when an employee leaves without notice.

Three limits shape every damages claim. First, you must mitigate your loss — a wrongfully dismissed employee is expected to make reasonable efforts to find new work, and earnings from a new job reduce the claim. Second, the loss must have been reasonably foreseeable when the contract was made. Third, there are no penalties for breach of employment contract in the punitive sense: UK contract law does not award punishment damages, and a clause imposing a penalty out of all proportion to the innocent party’s legitimate interest is unenforceable. A genuine pre-estimate of loss (liquidated damages) can be valid; a clause designed to terrify the other side into compliance will not survive.

Injunctions are rare in employment disputes. Courts will not order specific performance of a contract of employment — nobody can be forced to work for, or employ, someone. The main exception is the injunction enforcing restrictive covenants or confidentiality obligations, where an employer can ask the court to stop a former employee joining a competitor or misusing secrets. These applications move quickly and turn on precise drafting, which is why covenants need specialist drafting from the outset.

Practical Steps If Your Employment Contract Has Been Breached

How you handle the first days of a dispute often decides its outcome.

If you are the employee:

• Keep a contemporaneous record — dates, what happened, who was present, plus payslips, emails and letters.
• Raise the issue in writing, through the grievance procedure if there is one, and keep copies of everything.
• Do not delay. Tribunal time limits are brutally short, and delay can be treated as affirming the contract.
• If you stay, consider stating in writing that you work under protest and reserve your rights.
• Do not resign in the heat of the moment. Constructive dismissal claims fail more often than they succeed, and advice beforehand is far cheaper than regret afterwards.

If you are the employer:

• Act on evidence, not suspicion — investigate before concluding an employee has breached their contract.
• Follow your own disciplinary and grievance procedures; skipping them can itself create a breach.
• Do not withhold pay as a disciplinary tool unless the contract clearly permits the specific deduction.
• Put contract variations in writing and get genuine agreement — imposed changes are a leading cause of constructive dismissal claims.
• Review restrictive covenants regularly: an over-wide covenant is unenforceable, and an unenforceable covenant protects no one.

Breach of Employment Agreement vs Unfair Dismissal

People often use “breach of employment agreement” and “unfair dismissal” interchangeably, but they are different claims. Wrongful dismissal is the breach-of-contract claim: you were dismissed in a way that broke the contract, typically without the notice owed. It is about the contract, and the remedy is the money the contract would have provided. Unfair dismissal is a statutory claim: even with full notice, the dismissal was unfair for a statutory reason, such as a flawed process or an unfair reason. The two claims frequently run side by side — a dismissal without notice can be both wrongful and unfair — but they have different time limits, different caps and different eligibility rules.

When to Get Legal Advice

Breach of employment contract disputes turn on detail: the exact wording of the term, what was said and done, and how quickly you acted. Generic guidance can only take you so far. If significant money is at stake, if you are thinking of resigning, or if you have received a letter before action, speak to a specialist before your next move. Our guide to hiring an employment contract lawyer sets out what to ask and what it should cost.

A breach of employment contract does not have to end in a tribunal. Many disputes settle once both sides understand their contractual position — which usually starts with reading the contract properly, recording what happened, and getting advice early.
