If you’re wondering, can you dismiss an employee for being drunk at work, you’re not alone. Many UK employers find themselves in a tricky situation when an employee turns up under the influence. At EBS Law, we’ve guided countless businesses through these complex issues, balancing legal compliance with business protection.
Understanding the Legal Position on Alcohol at Work
Under UK employment law, being under the influence of alcohol at work can constitute gross misconduct. However, whether you can fairly dismiss an employee depends on a range of factors — including your internal policies, how the incident is handled, and the employee’s previous conduct.
Dismissal may be justified, but the process matters just as much as the offence itself. Employers must still act reasonably, follow fair procedures, and consider all relevant facts. Otherwise, you risk an unfair dismissal claim.
Can You Dismiss an Employee for Being Drunk at Work Without a Policy?
It’s strongly advisable to have a clear drug and alcohol policy. However, even without a formal policy, if an employee is drunk at work and their behaviour poses a safety risk or impacts their duties, you may be justified in taking disciplinary action — including dismissal in serious cases.
In the absence of a written policy, tribunals will still consider industry norms, the nature of the role, and whether the employer acted fairly and consistently.
What Counts as Gross Misconduct?
Being drunk at work may amount to gross misconduct if it endangers others, damages company property, or affects the employee’s ability to perform their job. Examples include:
- Operating machinery or driving under the influence
- Behaving abusively toward colleagues or customers
- Making serious mistakes due to intoxication
Even in such cases, the dismissal process must follow a fair disciplinary procedure to reduce the risk of claims.
Is a Dismissal Always Justified?
No. The question of can you dismiss an employee for being drunk at work is not black and white. You must consider mitigating circumstances, such as:
- Whether this is a first offence
- Whether alcohol dependency is a factor (which may count as a disability under the Equality Act 2010)
- Whether the employee self-reported the issue or sought help
Alcohol misuse might, in some cases, require support rather than punishment. An overly harsh response can lead to a tribunal ruling in the employee’s favour.
Do You Need to Carry Out an Investigation?
Yes, always. Even in seemingly clear-cut cases, it’s essential to carry out a proper investigation. This includes:
- Gathering statements from witnesses
- Reviewing any CCTV or records
- Providing the employee with a chance to respond
Only after a fair investigation can a disciplinary hearing be held. Jumping straight to dismissal — even for serious misconduct — risks making the dismissal procedurally unfair.
What If the Employee Poses a Safety Risk?
If someone is drunk and poses an immediate risk to themselves or others, you can suspend them on full pay while you investigate. Particularly in safety-critical roles such as transport, construction, or healthcare, this is often the safest and most appropriate first step.
According to Health and Safety Executive guidance, employers have a duty to ensure the safety of all employees — and that includes addressing alcohol misuse promptly and appropriately.

What Happens If the Employee Claims Alcohol Dependency?
If an employee reveals that they have an alcohol dependency, you may have additional responsibilities under the Equality Act 2010. While alcohol addiction itself is not automatically classed as a disability, the underlying health issues may be.
In these cases, consider making reasonable adjustments — such as referring the employee to occupational health, allowing time off for treatment, or adjusting duties — before resorting to disciplinary action.
Can You Require Alcohol Testing?
In safety-critical environments, some employers introduce random alcohol testing. If this is done, it must be clearly stated in the contract or company policy. Any testing must also be fair, proportionate, and carried out with the employee’s consent.
Without a policy or prior agreement, demanding a test may breach the employee’s rights and weaken your case at tribunal.
How to Dismiss an Employee for Being Drunk at Work to Protect Your Business
The best way to handle alcohol-related misconduct is to be prepared. We recommend:
- Implementing a clear alcohol and substance misuse policy
- Training managers on how to recognise and deal with issues
- Taking a consistent and fair approach to all disciplinary matters
Employers who document each step and follow a fair process are in a much stronger legal position should a claim arise.
