Introduction
In today’s demanding business environment, maintaining a safe and productive workplace is vital.
One common question employers face is: can you dismiss an employee for being drunk at work?
This issue involves legal, ethical, and operational considerations that every UK business owner or manager should understand clearly.
As specialists in outsourcing business solutions, Emberscale supports companies in navigating these complex HR challenges effectively.
In this post, we’ll explore the topic thoroughly, covering UK legal frameworks, company policies, alternatives to dismissal, and practical steps.
Our aim is to deliver comprehensive, actionable insights to help you make informed, fair decisions while staying compliant.
Understanding the Legal Framework in the UK
In the UK, employment is not “at-will” like in some other countries; dismissals must be for a fair reason and follow a fair procedure under the Employment Rights Act 1996.
Note for 2026: With the recent passage of the Employment Rights Act 2025, the qualifying period for unfair dismissal protection is shortening from two years to six months. While the full transition completes on 1 January 2027, this makes following a fair, ACAS-compliant process even more critical for new hires in 2026 who will gain protections much earlier than in previous years.
Being drunk or under the influence of alcohol at work can qualify as misconduct — and in serious cases, gross misconduct — which is a potentially fair reason for dismissal.
Gross misconduct typically includes behaviour that destroys trust and confidence, such as intoxication that endangers safety, risks accidents, damages reputation, or breaches a clear zero-tolerance policy.
The Health and Safety at Work etc. Act 1974 places a duty on employers to ensure, so far as is reasonably practicable, the health and safety of employees and others.
Knowingly allowing an intoxicated employee to continue working (especially in safety-critical roles) could expose the employer to prosecution or liability.
The Advisory, Conciliation and Arbitration Service (ACAS) Code of Practice on Disciplinary and Grievance Procedures is crucial — failure to follow it can increase tribunal compensation awards by up to 25%.
This means any dismissal process must include a reasonable investigation, a chance for the employee to respond, and a fair hearing.
Alcohol dependence itself is not considered a disability under the Equality Act 2010 (Schedule 1, para 1 excludes addiction to alcohol or other substances).
However, related conditions (such as depression or liver disease caused by long-term alcohol misuse) might qualify as disabilities, requiring reasonable adjustments if they meet the definition.
Employers must focus on conduct and performance impact, not the underlying condition alone.
Overall, yes — you can dismiss an employee for being drunk at work in the UK, but only if you follow a fair, documented process and the decision falls within the “band of reasonable responses.”
The Role of Company Policies and Procedures
A clear alcohol and substance misuse policy is essential for handling these situations consistently and defensibly.
Without one, employers risk unfair dismissal claims due to inconsistent treatment.
Your policy should explicitly prohibit being under the influence at work, define signs of intoxication (e.g., slurred speech, smell of alcohol, unsteady behaviour), and state potential consequences — up to and including summary dismissal for gross misconduct.
It should encourage early disclosure of problems and offer support, such as access to occupational health or counselling.
When an incident occurs, follow a structured process: remove the employee from duties immediately for safety, arrange safe transport home, document observations objectively (avoiding accusations), gather witness statements, and investigate promptly.
Hold a disciplinary meeting where the employee can explain, be accompanied, and appeal if disciplined.
Training line managers on recognising signs, documenting fairly, and following the ACAS Code ensures uniformity and reduces risks.
For remote or hybrid workers, policies should cover signs of impairment in video calls or performance dips.
A robust policy directly supports a positive answer to “can you dismiss an employee for being drunk at work” while promoting fairness and safety.
When Dismissal Is Appropriate
Dismissal is often justified when intoxication creates serious risks or breaches trust.
Examples include safety-critical roles (machinery operation, driving, healthcare), incidents causing accidents or near-misses, aggressive behaviour, or repeated violations.
If your policy clearly lists intoxication as gross misconduct and the impact is significant, summary dismissal (without notice) may be reasonable.
Tribunals assess whether the employer acted within the range of reasonable responses, considering factors like the employee’s role, length of service, previous record, and consistency of enforcement.
One-off incidents in low-risk roles might warrant warnings rather than dismissal.
Off-duty drinking is generally not grounds unless it affects work (e.g., chronic poor performance from hangovers).
In unionised workplaces, collective agreements may require progressive discipline or “just cause.”
In summary, yes — you can dismiss an employee for being drunk at work if the circumstances warrant it and you follow a fair process.
Alternatives to Immediate Dismissal
Dismissal isn’t always the first or only option; supportive approaches often yield better outcomes.
Treat alcohol issues as a potential health concern where possible.
Offer access to an Employee Assistance Programme (EAP), occupational health referrals, or counselling.
Consider temporary role changes or adjusted duties in safety-sensitive positions.
If dependence is disclosed, explore reasonable adjustments (if linked to a protected condition) or time off for treatment.
Use progressive discipline: verbal/written warnings, performance improvement plans, or suspension with pay during investigation.
Return-to-work agreements with monitoring (e.g., agreed sobriety expectations) can support rehabilitation.
These options reduce turnover costs, demonstrate compassion, and align with ACAS guidance that tribunals may view lack of support as unfair.
If help is refused and performance/safety issues persist, dismissal may become necessary.
By considering alternatives, employers answer “can you dismiss an employee for being drunk at work” with “yes, but explore support first” for stronger long-term results.
Hypothetical Scenario
The Challenge
You’re managing a mid-sized logistics firm where safety is critical.
One morning, a warehouse operative, Jamie, arrives for their shift slurring words, unsteady on their feet, and smelling strongly of alcohol.
Colleagues report Jamie nearly dropping heavy pallets near others.
This follows recent lateness and performance dips, but now it’s clear on-site impairment, risking accidents, insurance issues, and team morale.
As the business owner, you’re balancing operational needs, duty of care, and avoiding tribunal claims.
The Nuance
The grey area lies in balancing misconduct with potential health factors.
Jamie later mentions struggling with alcohol issues, but alcohol dependence isn’t a protected disability under the Equality Act 2010.
However, if linked to depression or another impairment, adjustments might be needed.
Immediate dismissal risks an unfair dismissal claim if procedure isn’t flawless, while ignoring it breaches health and safety duties.
The ACAS Code requires fair investigation, and tribunals scrutinise whether support was offered before discipline escalates.
The Resolution
Emberscale provides a step-by-step HR-led strategy to resolve safely while minimising risks and protecting your business.
First, remove Jamie from duties immediately, document observations factually from witnesses, and arrange safe transport home.
Second, conduct a prompt, private investigation meeting, allowing Jamie to respond and be accompanied.
Third, if impairment is confirmed, refer to EAP/occupational health for support; offer a return-to-work plan with clear expectations and monitoring if appropriate.
Fourth, follow progressive discipline or dismissal only if risks continue or support is refused, with full records to defend any claim.
Emberscale’s experts review/update your alcohol policy, coach managers, ensure ACAS compliance, and monitor to prevent recurrence — often substantially cheaper than tribunal costs, lost productivity, or reputational harm.

FAQ’s on Terminating an Employee for Being Drunk at Work
Q1: Do I need to carry out an alcohol test before dismissing an employee for being drunk at work in the UK?
A: Not necessarily. UK employers can rely on reasonable suspicion based on observable signs (such as slurred speech, unsteady gait, smell of alcohol, or impaired behaviour), supported by witness statements and objective documentation. Tribunals and ACAS guidance accept this as sufficient evidence in many cases, especially where safety is at risk. However, in safety-critical roles or where your policy requires it, voluntary or ‘for cause’ testing (e.g., breathalyser) can strengthen your position. Always follow a fair investigation process per the ACAS Code to avoid unfair dismissal claims.
Q2: Can I dismiss an employee for alcohol dependence if they haven’t come to work drunk?
A: Generally, no — alcohol dependence itself is not a protected disability under the Equality Act 2010 (addiction to alcohol is explicitly excluded). You cannot dismiss someone solely because they have an alcohol problem. However, if dependence leads to related issues like repeated poor performance, absenteeism, or capability concerns, you may take action — but treat it primarily as a health/support matter first. Offer referrals to occupational health, counselling, or an Employee Assistance Programme (EAP), and follow fair capability procedures if needed.
Q3: What immediate steps should I take if I suspect an employee is under the influence of alcohol at work?
A: Prioritise health and safety: Remove the employee from duties straight away (especially in safety-sensitive roles), ensure they do not drive or operate machinery, and arrange safe transport home. Document observations factually (without speculation), gather witness accounts, and follow your alcohol policy. Invite them to a prompt investigation meeting where they can respond and be accompanied (per ACAS Code). Consider suspension on full pay if the risk is serious, then decide on support, discipline, or dismissal based on findings.
Q4: Does the Equality Act 2010 protect an employee who attends work drunk due to alcohol dependence?
A: No — while related conditions (e.g., depression or physical health issues caused by long-term alcohol misuse) might qualify as disabilities requiring reasonable adjustments, alcohol dependence and current intoxication are not protected. Employers can enforce conduct rules against being under the influence at work, treating it as misconduct or gross misconduct. Tribunals uphold dismissals in such cases if a fair process is followed, but you should still explore support options like treatment referrals before escalating to dismissal.
Q5: How does handling intoxication at work differ in unionised versus non-unionised workplaces in the UK?
A: In non-unionised settings, you have more flexibility under the Employment Rights Act 1996, but must still follow fair procedures (investigation, hearing, appeal) and the ACAS Code to avoid unfair dismissal claims. In unionised workplaces, collective agreements often require additional steps — such as progressive discipline, ‘just cause’ standards, union involvement in meetings, or access to arbitration. Always check any recognised trade union agreement first, involve representatives early where appropriate, and ensure consistency to minimise tribunal risks in either case.
