Alcohol and work have always had a complicated relationship. From Friday drinks to client dinners and full-scale Christmas parties, alcohol is often woven into workplace culture. But when something goes wrong, the question quickly becomes: where does your responsibility as an employer begin, and where does it end?
What Does “Duty of Care” Actually Mean?
Under the Health and Safety at Work Act 1974, employers have a legal duty to take reasonable steps to protect the health, safety, and wellbeing of their employees; reinforced through decades of common law across physical safety, mental health, and protection from harassment and harm. Crucially, that duty doesn’t stop when someone walks out of the office. If it’s connected to work, it can fall within your responsibility, even if it happens on a Friday night at a venue you didn’t choose.
When Can Employers Be Held Responsible?
There’s no single rule that covers every situation. What courts and tribunals look at is whether you took reasonable steps to prevent foreseeable harm.
Work-organised events
If you organise, sponsor, or endorse an event where alcohol is available, such as a Christmas party, a team social, a celebration dinner, you’re likely to carry responsibility for what happens there. Off-site and after-hours doesn’t mean off the hook.
Excessive drinking
You’re not expected to police every glass. But if alcohol is freely available, there’s a culture of pressure to drink, or intoxication is obvious and unaddressed, failing to step in could be seen as a breach of your duty. Unlimited bars, drinking games, and cultures that normalise excess are all red flags.
Harassment and misconduct
This is one of the biggest areas of risk, and one where the law has recently become significantly stronger.
Since October 2024, under the Worker Protection (Amendment of Equality Act 2010) Act 2023, employers have a proactive legal duty to take “reasonable steps” to prevent sexual harassment in the workplace, including at work events. This duty applies not only to harassment by fellow employees but also potentially by third parties. It’s no longer enough to simply respond when something goes wrong, you have to proactively work to prevent it in the first place.
The Employment Rights Act 2025, will extend this obligation to require employers to take “all reasonable steps” to prevent sexual harassment, with this change proposed to commence in October 2026. It also introduces new provisions to prohibit employers from permitting harassment by third parties.
This sits alongside the Equality Act 2010, under which employers can be vicariously liable for discriminatory or harassing behaviour by their employees, including at social events, unless they can show they took all reasonable steps to prevent it. Alcohol is not a defence, for them or for you.
Getting home safely
Your duty of care can extend beyond the event itself. If someone leaves visibly intoxicated and is subsequently injured, questions could be asked about what steps you took to ensure their safe return.
Inclusion and psychological safety
Not everyone drinks, and the reasons are varied, from religion and health to pregnancy and personal choice. Under the Equality Act 2010, some reasons are capable of amounting to protected characteristics. A workplace culture that revolves around alcohol, or that subtly pressures people to participate, creates both legal risk and a real barrier to inclusion. If your team bonding relies on a bar tab, it’s worth asking what that says about your culture.
What Do “Reasonable Steps” Actually Look Like?
Have clear, up-to-date equality and harassment policies, and communicate expectations around alcohol consumption before events, not after something goes wrong. Your disciplinary policy should make clear that misconduct at work events is treated the same as misconduct in the workplace itself.
Offer meaningful non-alcoholic options, avoid incentivising heavy drinking, and consider drink limits where appropriate.
Keep an eye on how things unfold and step in early if behaviour is escalating.
The Bottom Line
The test, if it ever came to it, would almost always come back to this:
Was the harm foreseeable, and did you take reasonable steps to prevent it?
A healthy workplace culture makes expectations clear, respects individual choices, and doesn’t rely on alcohol to bring people together. Get that right, and you’re not just protecting your organisation from liability, you’re building a workplace where everyone feels safe, valued, and genuinely included.
