Dismissing an Employee 2026: UK Law, Process & Risks

Dismissing an employee is one of the highest-risk decisions an employer can make. Even where there are genuine performance issues, misconduct concerns or commercial pressures on the business, the legal framework governing dismissal in the UK is tightly regulated and heavily scrutinised by employment tribunals. What often exposes employers to claims is not the decision to dismiss itself, but weaknesses in the underlying reasoning, the way the process is handled, or a failure to properly identify the legal basis relied upon.

From an HR and business perspective, dismissal decisions sit at the intersection of legal compliance, workforce management, cost control and reputational risk. Poorly handled dismissals can lead to tribunal claims, uncapped compensation in discrimination cases, management time drain and long-term damage to employee relations. Conversely, a defensible and well-documented dismissal process can protect the business even where the outcome is challenged.

This guide is written for HR professionals and business owners who need clarity, certainty and legally robust decision-making when dismissing an employee. It assumes familiarity with basic HR processes and focuses on how UK employment law is applied in practice, how tribunals assess employer decisions, and where businesses most commonly get dismissal wrong.

What this article is about: This article explains when an employer can lawfully dismiss an employee in the UK, what process must be followed to ensure the dismissal is fair, and what legal and commercial risks arise if the decision is mishandled. It sets out the statutory framework under the Employment Rights Act 1996, the role of the Acas Code of Practice, and the interaction with discrimination law under the Equality Act 2010. Throughout, the focus is on employer action: what the law requires, what decisions must be made, and the consequences of getting those decisions wrong.

Section A: When can an employer lawfully dismiss an employee?

Before any dismissal decision is made, an employer must be clear about whether there is a lawful basis for bringing the employment relationship to an end. UK employment law does not allow employers to dismiss employees simply because the relationship has broken down or because the employer believes dismissal is justified on subjective grounds. The starting point for any lawful dismissal is whether the employer can identify and rely on one of the statutory “potentially fair” reasons for dismissal.

1. What are the five fair reasons for dismissal under UK law?

Under section 98 of the Employment Rights Act 1996, there are five potentially fair reasons for dismissing an employee:

• Conduct
• Capability or qualifications
• Redundancy
• Statutory illegality
• Some other substantial reason (SOSR)

These categories are exhaustive. If an employer cannot show that the reason for dismissal falls within one of these headings, the dismissal will be unfair, regardless of how reasonable the employer believed the decision to be. For a fuller explanation of how tribunals analyse the statutory test and fairness requirements, see unfair dismissal law and the overview guide to unfair dismissal.

From a practical HR perspective, the key risk is mislabelling the reason for dismissal. Tribunals look at the substance of the employer’s reasoning, not the label applied. Describing a dismissal as “redundancy” or “performance-related” will not protect the employer if the facts do not support that classification. That said, tribunals will focus on the employer’s genuine reason for dismissal rather than the label used, provided the facts support a potentially fair reason and the employer acted reasonably overall.

2. Why having a ‘fair reason’ is not enough on its own

Establishing a potentially fair reason is only the first step. Even where the reason for dismissal falls within one of the five statutory categories, the employer must also show that it acted reasonably in treating that reason as sufficient to justify dismissal in all the circumstances.

This is where many employers underestimate their risk. A dismissal can be unfair even if the employee has behaved badly, underperformed or become difficult to manage. Tribunals apply the “range of reasonable responses” test, asking whether the decision to dismiss was one that a reasonable employer might have made, not whether it was the decision the tribunal itself would have taken.

In practice, this means employers must be able to justify not only why they dismissed the employee, but why dismissal was an appropriate outcome at that point, rather than an alternative such as a warning, redeployment or further support.

3. How tribunals assess whether the employer’s reason is genuine

When assessing the fairness of a dismissal, tribunals will examine whether the stated reason was the true reason for dismissal or whether it was used as a pretext. Common red flags include:

• Decisions that appear to have been made before any investigation or consultation
• Evidence that the employer was motivated by an unrelated issue, such as personality conflict or cost-cutting
• Inconsistent treatment compared to similar cases within the organisation
• Retrofitting evidence after the decision to dismiss has already been taken

For employers, this makes contemporaneous documentation critical. Notes of meetings, investigation records and decision-making rationale often determine whether a dismissal is upheld or struck down. Even where the underlying reason is valid, poor documentation and unclear reasoning can undermine the employer’s case.

Section Summary: To lawfully dismiss an employee, an employer must be able to point to one of the five statutory fair reasons set out in the Employment Rights Act 1996. However, identifying a fair reason alone is not enough. The employer must also act reasonably in treating that reason as sufficient to justify dismissal, taking into account the specific circumstances of the case. Misclassifying the reason for dismissal, relying on post-hoc justifications or failing to document decisions clearly are common and costly mistakes that can expose employers to unfair dismissal claims even where there were genuine concerns about the employee.

Section B: What process must an employer follow when dismissing someone?

Even where an employer has identified a potentially fair reason for dismissal, the decision will still be unlawful if a fair process is not followed. In practice, most unfair dismissal claims succeed not because the employer lacked a valid reason, but because the process leading to dismissal was rushed, inconsistent or poorly evidenced. From a risk management perspective, procedure is often the employer’s strongest line of defence.

UK employment law does not impose a rigid, one-size-fits-all dismissal procedure. Instead, the law requires employers to act reasonably in all the circumstances, taking account of the size and resources of the business and the nature of the dismissal. However, certain procedural expectations are well established through statute, case law and the Acas Code of Practice.

1. What does a fair dismissal procedure actually require?

At its core, a fair dismissal procedure requires the employer to demonstrate that it has acted transparently, proportionately and consistently. While the precise steps will vary depending on the reason for dismissal, tribunals will usually expect to see the following elements:

• a reasonable investigation into the issues relied upon
• clear communication of the concerns to the employee
• an opportunity for the employee to respond before a decision is made
• consideration of alternatives to dismissal
• a right of appeal against the decision

These steps are not procedural formalities. Each plays a specific legal function. An investigation tests whether the employer’s concerns are factually sound. Giving the employee a chance to respond allows the employer to correct errors, identify mitigating factors and demonstrate procedural fairness. Considering alternatives shows that dismissal was not predetermined. The appeal stage provides a final safeguard against error and bias.

Where any of these elements are missing or treated as a tick-box exercise, the employer’s decision is vulnerable to challenge. For practical guidance on building defensible processes, see disciplinary procedure and hearing management guidance in disciplinary hearing resources.

2. When does the Acas Code of Practice apply?

The Acas Code of Practice on Disciplinary and Grievance Procedures applies directly to dismissals for misconduct and capability, including poor performance. While the Code does not have the force of law, employment tribunals must take it into account when assessing the fairness of a dismissal.

Failure to follow the Code does not automatically make a dismissal unfair. However, where an employer has unreasonably failed to comply with its guidance, a tribunal has the power to increase any compensation awarded by up to 25%. For employers, this means the Code operates as a de facto benchmark for fair process in conduct and capability dismissals.

The Code sets out clear expectations, including the need for warnings, time to improve where appropriate, the right to be accompanied at formal hearings, and a right of appeal. Departing from these principles without a strong justification significantly increases litigation risk.

3. When the Acas Code does not strictly apply

The Acas Code does not apply directly to redundancy dismissals, dismissals for statutory illegality or most SOSR dismissals. However, this does not mean that process is irrelevant in these scenarios. Tribunals will still expect employers to act reasonably, consult where appropriate and allow employees to make representations.

A common employer mistake is assuming that because the Code does not apply, a minimal or truncated process is acceptable. In practice, a lack of consultation or failure to engage with employee concerns can still render a dismissal unfair, particularly in redundancy and SOSR cases.

4. How the dismissal process changes depending on the reason

While the principles of fairness remain consistent, the procedural emphasis shifts depending on the reason for dismissal:

• Misconduct: focus on investigation, evidence, consistency and proportionality of sanction
• Capability: emphasis on support, warnings, training and reasonable time to improve
• Ill health capability: need for medical evidence, consultation and consideration of adjustments
• Redundancy: consultation, fair selection criteria and consideration of alternatives
• Statutory illegality: verification of legal barriers and exploration of alternative roles
• SOSR: careful justification of why dismissal is necessary and proportionate

Employers who apply a generic disciplinary process to all dismissal scenarios often fail to address the specific legal risks associated with the reason relied upon.

5. Why procedural fairness matters commercially

From a commercial standpoint, a robust dismissal process reduces exposure in three key ways. First, it increases the likelihood that the dismissal will be upheld if challenged. Second, it strengthens the employer’s negotiating position in any pre-claim settlement discussions. Third, it helps preserve employee relations and reduces the risk of knock-on grievances or attrition among remaining staff.

Conversely, procedural shortcuts may appear to save time in the short term but often result in higher costs through legal fees, compensation and management time spent dealing with tribunal proceedings.

Section Summary: A fair dismissal process is central to defending any dismissal decision under UK employment law. Employers must investigate properly, communicate concerns clearly, allow employees to respond and consider alternatives before deciding to dismiss. The Acas Code of Practice sets the benchmark for conduct and capability dismissals, and while it does not apply to every dismissal scenario, procedural fairness remains essential in all cases. Employers who treat process as an administrative burden rather than a legal safeguard significantly increase their exposure to unfair dismissal claims.

Section C: Can an employer dismiss an employee with less than two years’ service?

One of the most persistent areas of misunderstanding for employers is the significance of the two-year qualifying period for unfair dismissal. While it is correct that employees generally need two years’ continuous service to bring an ordinary unfair dismissal claim, this does not create a risk-free window in which employers can dismiss employees without legal or commercial consequence. In practice, short-service dismissals remain a common source of tribunal claims, particularly where the underlying reason for dismissal is poorly documented or coincides with a protected event.

1. What the two-year qualifying period actually means

Under the Employment Rights Act 1996, an employee must usually have at least two years’ continuous employment to qualify for the statutory right not to be unfairly dismissed. This qualifying period applies only to ordinary unfair dismissal claims.

For employers, this means that an employee with less than two years’ service will not normally be able to challenge the fairness of the dismissal itself before an employment tribunal. However, this does not remove the need for a lawful reason or careful decision-making. Other statutory and contractual protections continue to apply from day one of employment.

A frequent employer error is assuming that the absence of unfair dismissal protection means no justification is required. In reality, employers must still be able to show that the reason for dismissal was lawful, non-discriminatory and not prohibited by statute. For a detailed breakdown of the risks involved, see dismissal under two years’ service guidance.

2. Day-one dismissal risks employers still face

Even where an employee has less than two years’ service, a dismissal may still give rise to a tribunal claim if it falls within a category of automatically unfair dismissal or involves unlawful discrimination.

Automatic unfair dismissal claims do not require any qualifying period and arise where the reason for dismissal is connected with certain statutory rights or protected activities. These include dismissals connected with:

• pregnancy, maternity and other family-related rights
• whistleblowing or raising concerns about wrongdoing
• health and safety activities
• asserting rights under the Working Time Regulations, including holiday pay
• trade union membership or activities

Claims of this nature are particularly high-risk because compensation is uncapped and tribunals do not apply the usual “range of reasonable responses” test. For employers, this means the focus is on causation rather than reasonableness. Further explanation of these protections can be found in the automatic unfair dismissal and whistleblowing dismissal guidance.

In addition, discrimination claims under the Equality Act 2010 can be brought from day one of employment. If the dismissal is connected with a protected characteristic such as age, sex, disability, race or religion, the employer may face uncapped compensation and significant reputational damage.

3. Contractual and procedural risks in short-service dismissals

Even where an employee cannot bring an unfair dismissal claim, employers remain exposed to wrongful dismissal claims if they fail to give the correct notice or breach contractual dismissal procedures. This risk exists regardless of length of service.

Where an employer has a written disciplinary or dismissal policy that is expressed to be contractual, failure to follow that process can amount to a breach of contract, even for employees with only a short period of service. This is often overlooked in practice, particularly where policies have been incorporated into contracts by reference.

While a full disciplinary process is not always legally required for short-service dismissals, employers who follow a structured and documented approach are significantly better protected against discrimination, automatic unfair dismissal and contractual claims. From an HR governance perspective, consistency of approach also reduces the risk of employee relations issues and wider workforce disruption.

Section Summary: The two-year qualifying period for unfair dismissal does not give employers carte blanche to dismiss employees without risk. While ordinary unfair dismissal claims are usually unavailable to short-service employees, employers remain exposed to automatic unfair dismissal, discrimination and wrongful dismissal claims from day one. A disciplined, well-documented approach to short-service dismissals is therefore essential to minimise legal exposure and protect the organisation’s wider people strategy.

Section D: What notice must be given when dismissing an employee?

Notice is one of the most frequently mishandled aspects of dismissal and a common source of wrongful dismissal claims. Even where an employer has a genuine reason to dismiss and follows a fair process, failing to give the correct notice can result in separate contractual liability. From a risk management perspective, notice errors are largely avoidable and often undermine otherwise defensible dismissal decisions.

1. Statutory notice periods explained

Under the Employment Rights Act 1996, employees are entitled to a minimum statutory notice period once they have been employed for at least one month. The statutory minimum notice requirements are:

• one week’s notice if the employee has been employed for between one month and two years
• one week’s notice for each complete year of employment once the employee has two or more years’ service, up to a maximum of twelve weeks

Statutory notice operates as a legal floor rather than a ceiling. Where an employment contract provides for a longer notice period, the contractual notice entitlement will apply instead. Employers cannot contract out of statutory notice obligations.

A common employer mistake is miscalculating notice entitlement, particularly where an employee’s service is close to a threshold or where employment has been continuous across different roles within the organisation. Errors of this nature routinely give rise to wrongful dismissal claims, even where the dismissal itself would otherwise be fair.

2. Contractual notice and pay in lieu of notice

Many employment contracts allow the employer to terminate employment immediately by making a payment in lieu of notice (PILON). Where such a clause exists, dismissal without requiring the employee to work their notice will usually be lawful, provided the correct payment is made.

However, where there is no express PILON clause, terminating employment without allowing the employee to work their notice may amount to a breach of contract. In these circumstances, the employee may be entitled to claim damages for wrongful dismissal, including loss of salary and contractual benefits during the notice period.

Employers should also be aware of the tax treatment of notice payments. Payments made in respect of notice worked or under a contractual PILON clause are treated as earnings and subject to income tax and national insurance. Mishandling notice pay can therefore create both employment law and tax exposure. Further guidance is available in the payment in lieu of notice resource.

3. When summary dismissal is lawful

Summary dismissal, meaning dismissal without notice or payment in lieu, is only lawful where the employee has committed gross misconduct amounting to a fundamental breach of contract. This is a high threshold and must be assessed objectively by reference to the facts of the case.

Examples often cited as gross misconduct include theft or fraud, violence or threats of violence, serious breaches of health and safety, intoxication at work and serious insubordination. However, not all misconduct labelled as “gross” will justify summary dismissal. Tribunals will assess whether dismissal without notice fell within the range of reasonable responses available to the employer.

Over-reliance on summary dismissal is a frequent employer error. Employers who dismiss without notice in circumstances that do not meet the legal threshold risk liability for both unfair dismissal and notice pay. Detailed guidance on this threshold is set out in the gross misconduct analysis.

4. The importance of investigation and process in gross misconduct cases

Even in cases of apparent gross misconduct, employers are not entitled to dismiss “on the spot” without investigation. A fair disciplinary process must still be followed, including establishing the facts, allowing the employee to respond and considering any mitigating factors.

Failure to follow a fair process can undermine the employer’s reliance on gross misconduct and lead to liability for notice pay. In practice, many wrongful dismissal claims arise not because misconduct did not occur, but because the employer failed to carry out a defensible investigation or reached a premature decision.

Section Summary: Notice obligations are a distinct and critical component of lawful dismissal. Employers must ensure that statutory and contractual notice requirements are met, or that summary dismissal is justified by gross misconduct amounting to a fundamental breach of contract and supported by a fair process. Errors in notice entitlement or misuse of summary dismissal remain a common and avoidable source of wrongful dismissal claims.

Section E: Can an employer dismiss an employee for capability, sickness or disability?

Dismissals connected to capability, sickness absence or disability are among the most legally sensitive decisions an employer can make. These cases frequently sit at the intersection of unfair dismissal law and discrimination law, and errors can expose employers to uncapped compensation, regulatory scrutiny and long-term reputational damage. From an HR and risk management perspective, capability-related dismissals require careful planning, robust evidence and clear decision-making.

1. When capability is a potentially fair reason for dismissal

Capability relates to an employee’s ability to perform their role to the required standard. This may arise due to poor performance, lack of skill or aptitude, or health-related reasons that prevent the employee from carrying out their duties.

Capability is expressly recognised as a potentially fair reason for dismissal under section 98 of the Employment Rights Act 1996. However, tribunals expect employers to demonstrate that dismissal was a proportionate response. This requires evidence that the employer identified capability concerns, communicated them clearly, provided support or training where appropriate and gave the employee a reasonable opportunity to improve.

A common employer error is treating capability as a shortcut to dismissal, particularly where performance issues have been tolerated for a period of time. In practice, delay often increases legal risk, as tribunals may question why dismissal suddenly became necessary without earlier intervention or structured support.

2. Managing poor performance before dismissal

In non-health-related capability cases, employers should normally follow a staged process aligned with the Acas Code of Practice. This typically involves setting clear performance standards, issuing warnings, offering training or coaching and allowing sufficient time for improvement.

Performance expectations must be reasonable, role-specific and objectively measurable. Generalised criticisms such as an employee being “not up to standard” or “not a good fit” are rarely defensible without supporting evidence. Where targets are unrealistic, inconsistently applied or poorly documented, dismissal is unlikely to fall within the range of reasonable responses.

From a commercial perspective, early performance management not only reduces the risk of prolonged underperformance but also strengthens the employer’s position if dismissal later becomes unavoidable. Practical guidance is available in the capability dismissal resource.

3. Dismissal for ill health and long-term sickness absence

Capability dismissals arising from ill health require additional care. While long-term sickness absence can justify dismissal in certain circumstances, employers must be able to show that they acted reasonably and on the basis of up-to-date medical evidence.

Tribunals will typically expect employers to consider the nature of the illness, the likely duration of absence, the employee’s prognosis, the impact on the business and whether the employee is likely to return to work within a reasonable timeframe. Employers should also consult with the employee and, where appropriate, obtain occupational health advice.

Dismissing an employee without medical evidence or without meaningful consultation significantly increases the risk of an unfair dismissal finding. Detailed guidance on this area is set out in the dismissal for ill health guidance.

4. Disability, reasonable adjustments and Equality Act risk

Where an employee’s condition amounts to a disability under the Equality Act 2010, additional legal duties apply. Disability is defined broadly and can include physical or mental impairments that have a substantial and long-term adverse effect on normal day-to-day activities.

Employers are under a positive duty to make reasonable adjustments to remove or reduce disadvantages experienced by disabled employees. Adjustments may include changes to duties, working hours, workplace arrangements, equipment or support. Failure to comply with this duty can result in a standalone discrimination claim, regardless of length of service.

It is important to distinguish discrimination risk from unfair dismissal risk. A dismissal involving a disabled employee is not automatically unfair. However, dismissal is likely to be unlawful where the employer has failed to consider or implement reasonable adjustments or where disability-related factors materially influenced the decision. Further analysis of these risks is available in the reasonable adjustments and disability discrimination at work guidance.

5. When dismissal may be justified despite disability

Dismissal may still be fair and lawful where a disabled employee is genuinely unable to perform the role, even with reasonable adjustments, and where the ongoing impact on the business is significant. However, employers must be able to evidence why proposed adjustments were not reasonable, effective or practicable.

Tribunals will scrutinise whether alternatives such as redeployment were considered and whether the employer engaged meaningfully with the employee throughout the process. A predetermined outcome or lack of consultation often undermines the employer’s position, even where the underlying capability concerns are genuine.

Section Summary: Capability, sickness and disability-related dismissals carry heightened legal risk and require an evidence-led, proportionate approach. Employers must distinguish between performance and health issues, follow fair procedures, obtain medical evidence where appropriate and comply with their duty to make reasonable adjustments. Dismissal should be treated as a last resort, supported by clear documentation and defensible reasoning, to minimise exposure to unfair dismissal and discrimination claims.

Section F: How should employers lawfully dismiss employees for redundancy?

Redundancy dismissals are frequently driven by genuine commercial pressures, but they remain one of the most litigated forms of dismissal. Employers often assume that financial difficulty or restructuring automatically justifies redundancy, yet tribunals focus far more closely on whether the legal definition of redundancy is met and whether a fair process has been followed. From a compliance and HR strategy perspective, redundancy dismissals expose employers to risk at every stage of decision-making.

1. What legally counts as redundancy?

Redundancy has a specific statutory meaning under section 139 of the Employment Rights Act 1996. A dismissal will be by reason of redundancy where it is wholly or mainly attributable to:

• the employer ceasing or intending to cease the business
• the employer ceasing or intending to cease business at a particular location
• a reduced requirement for employees to carry out work of a particular kind

Redundancy is therefore not simply about reducing headcount or cutting costs. If the work continues broadly unchanged and employees are dismissed for reasons unrelated to a reduced need for that work, the dismissal may not be a genuine redundancy, regardless of how it is described.

A common employer error is using redundancy as a mechanism to remove underperforming or problematic employees. Tribunals will look behind the redundancy label and examine whether the role itself genuinely disappeared or diminished. For a detailed overview of redundancy law and process, see redundancy guidance.

2. Fair selection pools and criteria

Where a genuine redundancy situation exists, employers must apply a fair selection process. This usually involves identifying an appropriate selection pool and applying objective, evidence-based selection criteria.

Selection criteria should be capable of independent verification and applied consistently across the pool. Common criteria include skills, qualifications, experience, performance records and disciplinary history. However, criteria that appear neutral can still be indirectly discriminatory if applied without adjustment.

For example, using attendance records without discounting disability-related or maternity-related absence can expose employers to discrimination claims. Similarly, relying on subjective assessments without contemporaneous evidence increases the risk of successful challenge. Further guidance on this area is available in the redundancy selection criteria resource.

3. Consultation obligations and employee engagement

Meaningful consultation is a cornerstone of fair redundancy dismissal. Employers must consult with affected employees before final decisions are taken, allowing them to understand the proposals, challenge assumptions and suggest alternatives.

Consultation must be genuine and not a rubber-stamping exercise. Tribunals are alert to situations where employers have pre-selected employees or roles before consultation begins. A predetermined outcome is a common reason redundancy dismissals are found to be unfair.

Where an employer proposes to dismiss 20 or more employees at one establishment within a 90-day period, collective consultation obligations apply. These include consultation with appropriate employee representatives and statutory notification requirements. Failure to comply can result in protective awards of up to 90 days’ pay per affected employee, in addition to unfair dismissal liability. Detailed obligations are set out in the redundancy consultation guidance.

4. Considering alternatives to redundancy

Employers are expected to consider reasonable alternatives to redundancy, including suitable alternative employment within the organisation. This obligation is particularly important where vacancies exist or where retraining could enable redeployment.

Failure to properly consider alternatives can render a redundancy dismissal unfair, even where the business rationale for restructuring is sound. From a commercial perspective, redeployment may also preserve institutional knowledge and reduce future recruitment costs.

5. Common redundancy dismissal failures

From a risk management perspective, the most common redundancy pitfalls include:

• selecting employees before consultation begins
• using unclear, subjective or biased selection criteria
• failing to document scoring decisions
• ignoring suitable alternative roles
• treating consultation as a procedural formality

Each of these failures can independently undermine the fairness of the dismissal and expose the employer to claims.

Section Summary: Redundancy dismissals require more than a sound business rationale. Employers must demonstrate that a genuine redundancy situation exists, apply fair and objective selection processes, consult meaningfully with affected employees and consider alternatives to dismissal. Procedural failures, rather than commercial justification, are the most common reason redundancy dismissals are successfully challenged.

Section G: What happens if an employer gets a dismissal wrong?

When dismissal decisions are mishandled, the consequences for employers extend well beyond the loss of the employee concerned. Legal liability, financial cost, management time and reputational damage frequently outweigh any short-term benefit gained from a rushed or poorly reasoned dismissal. From a compliance and governance perspective, understanding the full risk profile of dismissal is essential to defensible employer decision-making.

1. Unfair dismissal claims and tribunal scrutiny

Where an employee has the requisite qualifying service, an unfair dismissal claim is the primary legal risk arising from a flawed dismissal. To defend such a claim, the employer must show that the dismissal was for one of the five potentially fair reasons under the Employment Rights Act 1996 and that it acted reasonably in all the circumstances, including following a fair procedure.

Employment tribunals scrutinise both the substance of the dismissal decision and the process followed. Even where a fair reason is established, procedural failures such as inadequate investigation, lack of consultation, failure to allow representation or the absence of an appeal can result in a finding of unfair dismissal.

If an unfair dismissal claim succeeds, the tribunal may award compensation comprising a basic award and a compensatory award. The compensatory award is intended to reflect actual financial loss arising from the dismissal and is subject to a statutory cap in ordinary unfair dismissal claims. In rare cases, tribunals may order reinstatement or re-engagement, although these remedies are infrequently imposed and often resisted by employers due to a breakdown in trust and confidence. Further analysis of tribunal outcomes is available in the employment tribunal compensation guidance.

2. Wrongful dismissal and contractual exposure

Wrongful dismissal is a separate legal risk concerned with breach of contract rather than fairness. It most commonly arises where an employer fails to provide the correct statutory or contractual notice, or dismisses summarily without being contractually entitled to do so.

Unlike unfair dismissal, there is no qualifying service requirement for a wrongful dismissal claim. This means that even short-service employees may pursue claims where contractual obligations have been breached. Damages are typically limited to the financial losses the employee would have received had the contract been terminated lawfully, such as salary, benefits and accrued entitlements during the notice period.

For senior employees with lengthy notice periods or enhanced contractual benefits, wrongful dismissal exposure can be significant. Employers who focus exclusively on unfair dismissal thresholds often underestimate this risk. A broader overview of this exposure is set out in the wrongful dismissal guidance.

3. Discrimination and automatic unfair dismissal risks

Dismissals connected to protected characteristics or statutory rights present the highest level of legal risk. Claims for discrimination under the Equality Act 2010 and claims for automatic unfair dismissal do not require any qualifying period of service and compensation is uncapped.

In these cases, tribunals do not apply the usual “range of reasonable responses” test. Instead, the focus is on causation. If a prohibited reason materially influenced the dismissal decision, liability is likely to follow, regardless of the employer’s intentions or the fairness of the process.

In addition to financial exposure, findings of discrimination or automatically unfair dismissal carry substantial reputational risk, particularly where decisions are published or affect employer brand, regulatory standing or client confidence.

4. Commercial and operational consequences

Beyond legal liability, poorly handled dismissals can have lasting operational consequences. Tribunal proceedings are time-consuming and divert management attention from core business activities. Employee morale may be damaged where dismissals are perceived as arbitrary or unfair, increasing attrition and grievance risk.

Conversely, a defensible dismissal process can deter claims altogether or lead to early resolution on favourable terms. Employers who can clearly articulate their reasoning and demonstrate procedural fairness are better positioned to manage disputes before they escalate. Practical insight into tribunal exposure and process is available in the employment tribunal claims overview.

Section Summary: Getting dismissal decisions wrong exposes employers to layered legal risk, including unfair dismissal compensation, wrongful dismissal damages and uncapped liability for discrimination or automatic unfair dismissal. These risks are often compounded by reputational harm and operational disruption. Treating dismissal as a compliance-critical decision, supported by clear reasoning, fair process and careful documentation, is essential to protecting the business.

Dismissing an employee FAQs

1. When is it fair to dismiss an employee?

A dismissal will only be fair if it is for one of the five potentially fair reasons set out in the Employment Rights Act 1996 — conduct, capability, redundancy, statutory illegality or some other substantial reason — and the employer acts reasonably in treating that reason as sufficient to justify dismissal. This includes following a fair and proportionate procedure in all the circumstances.

2. Can an employer dismiss an employee without a warning?

Yes, but only in limited circumstances. In cases of gross misconduct, dismissal without prior warnings may be fair, provided the employer has carried out a proper investigation and followed a fair disciplinary process. In performance or minor misconduct cases, dismissal without warning is unlikely to fall within the range of reasonable responses.

3. Can an employee be dismissed while on sick leave?

An employee can be dismissed while on sick leave, but the dismissal must not be because of the sickness absence itself without proper consideration. Employers must obtain appropriate medical evidence, consult with the employee, consider reasonable adjustments and assess whether the employee is likely to return to work within a reasonable timeframe. Additional legal risk arises where the sickness relates to a disability.

4. How much notice must be given when dismissing an employee?

Statutory notice is one week if the employee has been employed for between one month and two years, and one week for each complete year of service thereafter, up to a maximum of twelve weeks. Where the employment contract provides for longer notice, the contractual notice period will apply.

5. What is the difference between unfair dismissal and wrongful dismissal?

Unfair dismissal is a statutory claim based on the absence of a fair reason or fair process and usually requires two years’ continuous service. Wrongful dismissal is a contractual claim based on breach of notice or dismissal procedures and does not require any minimum length of service.

6. Can an employee be dismissed without notice?

Yes, but only where the employee has committed gross misconduct amounting to a fundamental breach of contract. Even in these cases, the employer must carry out a fair investigation and disciplinary process before deciding to dismiss.

7. What records should employers keep when dismissing an employee?

Employers should retain investigation notes, correspondence, meeting records, evidence relied upon, decision-making rationale and appeal documentation. These records are often decisive in defending tribunal claims.

Conclusion

Dismissing an employee is a legally regulated and commercially sensitive decision. While employers are entitled to manage performance, conduct and workforce size, the law requires dismissals to be grounded in a recognised statutory reason and supported by a fair and proportionate process. Most tribunal claims arise not because employers lacked justification, but because decisions were rushed, poorly evidenced or procedurally flawed.

For HR professionals and business owners, effective dismissal management depends on disciplined decision-making. This includes identifying the correct legal basis for dismissal, applying the appropriate process for the circumstances, and documenting each stage carefully. Shortcuts may appear efficient, but they frequently result in greater cost, disruption and reputational damage.

When handled correctly, dismissal processes protect organisations not only from legal exposure but also from longer-term harm to employee relations, culture and employer brand.
