Lawyer reveals everything you should absolutely not do at work Christmas party

'Tis the season to be cautious...

It's that time of year again when people across the globe finish off deadlines, don their best sparkly outfit, drink copious amounts of prosecco and unwind at their annual Christmas work party.

Now, while it's a great time to relax, mark the year’s achievements, and enjoy time with your colleagues outside of the 9 to 5 office slog, too much alcohol and lowered inhibitions can see things slip pretty fast.

The best outcome is a few hours of beer fear and a light hangover, while the worst outcome can lead to disciplinary action or even dismissal after not striking the right balance between festive celebration and workplace boundaries.

So, to help you navigate your next work bash, employment lawyers at Weightmans have helpfully mapped out seven key no-nos to bear in mind.

Drinking during work hours

Now, the first four tips are all centred around, you guessed it, alcohol.

Drinking during work hours is usually not allowed under workplace policies, and while there is no specific law banning it, breaching internal rules can lead to warnings, suspension, or dismissal in serious cases.

So, because of this, the experts suggest that employers should be clear about expectations during the festive period, including any flexibility around hours, parties, or events.

Clear communication ahead of time can avoid some major confusion later down the line while also keeping productivity on track.

Drinking before work the next day

Unfortunately for those who get killer hangovers even after one cocktail, many work parties fall midweek, meaning that you'll most likely be expected to work the following day.

A heavy night can carry real consequences the following morning if you find yourself turning up to your shift under the influence, as this can lead to disciplinary action, especially in safety-critical roles.

Drinking to excess

This is generally just a good tip to follow when it comes to any social event involving booze.

Whether it's arguments or full-blown physical confrontations, alcohol often sits behind incidents that lead to complaints or disciplinary action.

So, in order to make sure you don't overdo it on the tipples, maybe zebra-stripe with non-alcoholic or lower alcoholic options and try your hardest not to treat the free bar like an all-you-can-eat buffet.

Inappropriate comments or advances

Compliments, jokes, and flirtation can cross lines quickly in a professional setting, so be sure you're thinking about what you say or do before actually saying or doing it.

A few extra seconds of reflection can save you and your co-workers a whole load of HR meetings later down the line.

Calling in sick

According to figures from Benefits and Pensions Monitor, sickness absence rose by 61 per cent after a major Christmas party day in 2022, which is a trend likely to be repeated.

Absence can put pressure on teams and managers alike.

But, obviously, if you're too unwell to work then you're too unwell to work - there's not much you can really do about that!

Inappropriate conduct outside work

The risks surrounding festive nights out do not end at the party door, as you can get into a whole bunch of legal trouble for inappropriate conduct in public.

Being drunk and disorderly in public can lead to fixed penalty notices or arrest. Fines can reach £80 for a penalty notice, or up to £1,000 if prosecuted.

Public urination is illegal and treated as a public nuisance, with fines of up to £100 under local bylaws or the Public Health Act 1936. Drinking in the street may also breach Public Space Protection Orders, carrying on-the-spot fines of up to £100.

Behaviour outside work can still affect employment if it damages trust, reputation, or the ability to do the job.

Sejal Raja, Employment Lawyer at Weightmans, said: "The office end-of-year party is a great way to celebrate achievements and build team morale, but it’s essential to strike a balance between fun and professionalism. Employers have a duty to ensure the event remains inclusive and respectful, which means setting clear expectations in advance about behaviour and providing a safe environment for everyone.

"Employees, too, should be mindful that while the party is a social occasion, it’s still linked to the workplace, and inappropriate behaviour can have serious consequences. By maintaining mutual respect, everyone can enjoy the festivities without fear of crossing any boundaries."

Well, there you have it!
