The office Christmas party: how to enjoy it and still have a job
It's a party, and it's also work with a paper hat on. How to dress, what to drink, who to talk to, where the line now sits, and what to do the morning after.
Nobody gets promoted for their dancing at the office Christmas party, though more than one man has spent January wishing he had gone home an hour earlier. The evening is a strange thing: free drinks, a loud room and the same people you sit beside all year, now in better shirts and with their guard down.
None of this means you should treat it as a threat. It should be a good night, and the man who enjoys it properly, talks to people and leaves in good order does himself more good than he realises. All it takes is remembering one thing: it’s a party, and it’s also work.
| Moment | Do this | Not this |
|---|---|---|
| Before you go | Eat, and sort out how you’re getting home | Start early at the desk on an empty stomach |
| The first hour | Find the organiser and say thank you | Stand with the same three people you see every day |
| At the bar | Alternate with something soft | Buy rounds of shots for the junior team |
| With the boss | Five friendly minutes, about anything but work | Your pay, your rival or your big idea |
| The end | Say your goodbyes and check that others are sorted | “One more” at wherever is still open |
| The next day | On time, dressed, and pleasant about it | A sick note or a long story |
Before you go
Read the invitation. It should tell you the time, the place, whether partners are coming and what people are expected to wear. Then answer it, promptly, because somebody is counting heads. A day is plenty.
Eat something proper before the first drink, even if food is promised, because party food can be late and small. And decide now how you’re getting home: book the taxi, check the last train, or agree a lift with someone who isn’t drinking. A plan made at six o’clock is a far better plan than one made at midnight.
What to wear
Follow the invitation first, and dress for the occasion rather than for yourself. If it says black tie, do it properly. If it says nothing, go one notch smarter than your usual working clothes: a good jacket, a clean shirt and proper shoes, with a tie in your pocket if you’re not sure. It’s easy to take off, and impossible to find at seven o’clock.
Leave the novelty jumper to the people who can really carry it off, unless the invitation asks for one, in which case wear it cheerfully. A man who refuses to join in looks more foolish than a man dressed as a reindeer.
Who to talk to
This is the real value of the evening, and it’s wasted if you stand with your usual crowd. Talk to someone from another team. Find the new starter who knows nobody and introduce them to someone. Speak to the people from reception, the post room and the cleaning team, if they’re there, and speak to them the way you’d speak to the chairman.
Say hello to the senior people, briefly and without an agenda. Ask about their plans for Christmas. Don’t raise your pay, your promotion or the failings of a colleague: a loud table with a drink in your hand is the wrong place for any of them, and the person you’re talking to will remember that you tried. If somebody brings a partner, include them, because they may know nobody there and won’t want an hour of shop talk.
Keep your gossip for another day, too. Assume that anything you say about a colleague at a party will reach them, with improvements.
Be the person people are glad they talked to, and the one nobody has a story about on Monday.
The drink
A free bar makes it hard to keep count, so count on purpose. Have a soft drink between alcoholic ones, and stop one before you need to. For scale, the NHS says a 750ml bottle of 13.5% wine holds 10 units, and advises not regularly drinking more than 14 units a week.
Not everybody drinks, and they don’t owe anyone an explanation. Never press a drink on someone who has said no. That goes double if you’re senior, because a junior colleague may find it hard to refuse you.
Where the line is
This part is simple, and this year it matters more. In Britain, the Equality and Human Rights Commission updated its guidance on 30 October to reflect a stronger law: employers must now take “all reasonable steps” to prevent sexual harassment, and from that date they can be liable for harassment of their workers by third parties unless they’ve taken all reasonable steps to prevent it. The guidance says an employer’s policy should state that harassment may lead to disciplinary action, up to and including dismissal, if it’s committed in any situation related to work, “such as at a social event with colleagues”. So the party counts.
Acas, the workplace advice service, is plain about what sexual harassment covers. Its examples include remarks about someone’s body or clothing, questions about their sex life, offensive jokes, and touching someone against their will, for example hugging them. Behaviour can count even if you didn’t intend it that way, and what some people consider joking or banter can still be harassment. Complaints and tribunal claims can be made against individuals as well as employers. This isn’t legal advice, but the practical version needs no lawyer:
- Keep your hands to yourself, unless you’re shaking someone’s.
- Leave people’s bodies and love lives out of the conversation.
- Take no for an answer the first time, including a no that comes in the form of an excuse.
- Remember who’s senior. Someone who reports to you may be polite because they feel they have to be.
- If you’d need to check who’s in earshot before telling a joke, don’t tell it.
When someone else is in trouble
Keep an eye out, because this is where a decent man earns his keep. If a colleague has had too much, get them some water and a seat, and make sure they get home. Don’t film it, don’t tell the story on Monday, and don’t let them drive.
If you see someone being harassed, Acas says you could try to stop it, but only if you feel it’s safe and appropriate to do so. Our suggestion is to walk over and start a conversation with the person on the receiving end, which often ends the moment without a scene. Afterwards, Acas says you can support their complaint, report what you saw or act as a witness, and that it’s a good idea to note what happened, with dates, times and names. You must not be treated unfairly for making or supporting a complaint, or for giving evidence.
Phones and photographs
Group photographs at the start of the evening are fine. Anything later, when ties are loose and judgment looser, stays off the company chat and off social media. Ask before you post a photograph of anyone, and if somebody asks you to delete one, delete it without argument.
Leaving, and the morning after
Go while you’re still enjoying it. Find the organiser, say thank you and leave. The conversation you’d have at the third venue isn’t one you need to have.
Be careful about the car, that night and the next day. GOV.UK says it’s impossible to say exactly how many drinks equal the legal limit, because it differs from person to person, and the limit is lower in Scotland than in the rest of the UK. The NHS says the average adult can process around one unit in an hour, though this varies. A bottle of wine is 10 units, so finishing one at midnight could leave you with alcohol in your blood well into the morning. Driving over the limit can bring six months in prison, an unlimited fine and a ban of at least a year. Take the train, or get a lift.
Then turn up on time, however you feel. And send a short note to the organiser: thank them in writing, by name, because it’s a thankless job and they’ve probably been at it for weeks.
If you got it wrong
Go and see the person, early and privately. Apologise once, plainly and without a “but”. Don’t blame the drink, and don’t ask them to tell you it’s all right. Then behave so well for the next few weeks that the apology looks true. If what happened was serious, or someone has complained, don’t try to smooth it over yourself: leave them alone, follow your employer’s procedure, and take proper advice if you need it.
Questions people ask
Do I have to go?
A good employer won’t lean on anyone who has a reason to stay away. If you can, go for an hour: you’ll be seen, you’ll have thanked the organiser, and you can leave with a clear conscience. If you really can’t face it, decline politely and early, and keep your reasons short.
Should I leave before the boss?
There’s no rule. Stay as long as you’re enjoying yourself and behaving well, then say goodbye. If the boss is still there at closing time, that’s the boss’s business.
What if I’m the one in charge?
Then you’re working. Drink little, talk to everyone and keep any toast short. Make sure people have a way of getting home, and that anyone who needs help knows who to ask. Your behaviour sets the limit for everyone else’s, so set it sensibly.
Can I bring my partner?
Only if the invitation says so. If it does, tell them who’s who beforehand, stay with them for the first half-hour, and rescue them from anyone who starts explaining the sales pipeline.
How we wrote this: the legal points are from the Equality and Human Rights Commission’s harassment guidance (updated 30 October 2026) and Acas’s sexual harassment pages. Drink-driving limits and penalties are from GOV.UK, and the alcohol units and guidance from the NHS, all read on 2 November 2026. They apply in Britain or the UK; other countries differ. The rest is our opinion, it isn’t legal advice, and nobody paid to appear here. Please drink responsibly.
