Addiction in the workplace is common, but it is not widely discussed.
There are laws protecting the rights of employees with addictions, and both external and in-work support is available. For both employees worried about substance use and employers looking to support their team, it is important to understand the regulations and how to access help.
Addiction in the workplace is more common than most people realise
A 2025 Bupa study found almost six in 10 UK employees (57%) say they’ve experienced addiction in some form. Nearly half (48%) use addictive behaviours to cope with workplace stress. 51% say stigma stops them asking for help.
The NHS defines alcohol use disorder as drinking in a way that’s harmful. That may mean regularly drinking more than you intend to, or finding it hard to stop even when it’s causing problems at home or work. The same patterns are found in drug addiction.
Worried about your own substance use at work?
If you’re reading this because you’re worried your drinking, drug use or even your behavioural addiction such as social media is affecting your work, that’s a sign that it probably is.
You don’t have to have reached crisis point to ask for help
The ‘rock bottom’ idea is a myth. People wait until things are really bad before reaching out, and that costs them years. Asking earlier helps address the underlying issues and avoid the more serious consequences.
Does addiction in the workplace affect your employment rights?
Addiction itself isn’t classed as a disability under the Equality Act 2010. However, substance use disorders often go hand in hand with mental health challenges and physical illnesses that are recognised disabilities. If these apply to you, your protections are the same as any other employee’s.
ACAS reminds employers they have a duty of care for workers’ health, with mental and physical health treated equally. If you’re worried about disclosing, read your employer’s drug and alcohol policy in full. According to TUC guidance, a good policy should make clear:
- Any request for help will be treated confidentially
- Absence for treatment will be treated as normal sickness absence
- Alcohol or drug use is a medical matter first
Can you be ‘sacked’ for being an alcoholic?
No. An employer can’t dismiss you simply because you’re living with alcohol addiction. The law looks at what you do at work, not the diagnosis. Action can be taken if your work or safety on the job is affected, but a fair process is needed either way. The TUC and most unions argue alcohol and drug use should be handled as a medical issue first. If you’re not sure where you stand, talk to your union rep or HR.
“Can my employer fire me for going to rehab?” – Seeking treatment doesn’t have to mean risking your job
This is often the worry people raise first. Fear of losing their livelihood keeps many out of treatment when they know they need it. In most cases, residential or outpatient rehab is arranged through medical leave, like any other health condition. For many, the first stage is alcohol detox, followed by alcohol use disorder treatment that works on what’s underneath the drinking or drug use.
Telling your employer is usually best because it allows them to plan ahead. Some employers are more supportive than people expect. If you’re not sure where you stand, ACAS or your union rep can talk it through, so you can decide how to raise it.

If you’re an employer concerned about a member of your team
If you’re noticing changes in someone on your team, the first conversation is key. UK and Irish law is careful about treating the changes as misconduct, but some managers don’t realise this.
Understanding addiction as a health issue, not a conduct issue by default
The NHS’s definition of addiction recognises that people find it hard to stop, even when it’s affecting their health or work. Treating it as misconduct usually makes things worse for the team and the business. UNISON finds that addiction often develops as a way of coping with work-related stress. For managers and business owners, this means considering whether the workplace itself is part of what’s driving the addiction.
Can you dismiss an employee for being drunk at work?
You can take action where there’s a clear breach of conduct, like turning up intoxicated to a safety-critical job. A fair process is required. In many cases, offering support alongside or instead of discipline is legally safer, and more likely to work. If the underlying condition qualifies as a disability under the Equality Act, you may also have duties around reasonable adjustments. ACAS is the place to start for clearer guidance.
What UK and EU employment law says – a brief overview
In the UK, the main rules are the Equality Act 2010 and ACAS guidance on fair process. The Health and Safety at Work Act 1974 adds a duty of care for employees’ health and wellbeing. So in practice:
- Employers have a duty of care for employees’ health and wellbeing
- Mental and physical health matter equally
- Any dismissal must follow a fair process, with proper documentation and support offered along the way
Ireland is broadly similar. The Irish Law Society notes that alcohol and drug addictions respond to treatment, and employees shouldn’t be discriminated against because of the illness. IBEC advises managers to handle disclosure with confidentiality and without judgement.
Across the EU, support comes mainly from occupational health and safety law. The European Union Drugs Agency notes member states usually treat addiction as a health issue, with confidential counselling and Employee Assistance Programmes. Rules vary by country.
Castle Health isn’t a legal resource, and specific questions should be directed to ACAS, HR, or an employment solicitor.
How to raise the subject with an employee – and why how you do it matters
ACAS lays out a few useful principles for having the conversation sensitively:
- Focus on what you’ve observed (lateness, missed deadlines). Leave the cause aside until you’ve heard from them.
- Choose a private setting and a calm time, away from other colleagues
- Frame the conversation around support
- Listen more than you speak
If you came here searching for ‘how to deal with an alcoholic employee’, the words matter. Calling someone an alcoholic, or talking about ‘an addiction problem’, tends to shut the conversation down. ‘What’s going on, and what might help?’ usually opens it up.
"I'm 5 years sober now and I know I wouldn't have survived another month before I joined the treatment programme. Castle Craig is an amazingly special place where miracles really do happen, I'm blessed to have found you."
Addressing addiction in the workplace benefits everyone
Treating addiction in the workplace as a health issue is the legal and compassionate thing to do. It’s also good economics. The Institute of Alcohol Studies puts the wider cost of alcohol to society at £21–52 billion a year, much of it from absenteeism and lost productivity. Treating addiction harshly only drives the problem underground, and the longer it stays hidden, the more expensive it gets.
Frequently asked questions about addiction in the workplace
Does my employer have to keep my addiction confidential?
Health information is covered by data protection law in the UK and Ireland. Anything you share about your addiction or treatment counts as sensitive personal data. It can only be shared with people who need to know, and with your consent in most cases.
What is an Employee Assistance Programme (EAP) and does my company have one?
An EAP is a confidential support service many employers provide for free. Most offer a set number of counselling sessions, often including specialist support for alcohol and drug use. You can usually self-refer without your manager knowing.
Can I return to my job after completing addiction treatment?
Yes, in most cases. The TUC and the Irish Law Society both consider addiction treatable, and returning to work as a normal part of recovery. Your employer may agree a phased return or workload adjustments. Our aftercare helps prepare for that.
What should I do if I think a colleague has a substance use disorder?
Don’t act alone, and don’t assume. Speak to HR or your line manager in confidence. Find out whether your company has an Employee Assistance Programme, and what the drug and alcohol policy says about raising concerns. The person may already be looking for a way to ask for help. A respectful conversation can be the opening.
