Why Christmas Parties Should Still Keep HR Awake at Night

December brings mince pies, music, and merriment (along with that building feeling of panic that you have so much more to fit into each day than usual), but it also brings some of the riskiest moments in the employment calendar – Christmas social events!

It’s worth remembering that we’re not just concerned about the office Christmas party!  Not every risky event carries the company’s logo. Informal team drinks, client celebrations, or social media meet-ups that stem from work relationships can still be treated as work-related events.  Behaviour that crosses the line – bullying, harassment, or discrimination, may expose both the individual and employer to liability, especially if managers were present or the event was work-adjacent. For those in regulated sectors, poor behaviour even at non work-related gatherings can also amount to misconduct, raising questions of integrity and fitness to practise.  Regulators have been increasingly clear that unacceptable conduct outside working hours can damage public trust and professional reputation and those behaving poorly have found themselves out of a job!

Since October 2024 the stakes have been even higher, the Worker Protection (Amendment of Equality Act 2010) Act 2024 imposed a statutory duty on employers to take reasonable steps to prevent sexual harassment at work.  That duty extends to work-related social events. If a complaint arises after a Christmas social event, tribunals will consider whether the employer had genuinely taken preventive measures, not just whether it reacted appropriately afterwards.

Add alcohol, blurred boundaries, and social media into the mix, and it’s easy to see how goodwill can unravel into grievance, misconduct, and reputational harm. The best strategy is prevention – thoughtful planning, clear expectations, and a reminder that fun and professionalism can happily coexist.

It may be worth a reminder that liability doesn’t rest solely with the employer.  Individuals can be personally liable for acts of discrimination or harassment they commit in the course of employment – including at work-related social events – especially if the employer has taken reasonable preventative steps.

The “it was just banter” defence rarely holds up, and tribunals take a dim view of behaviour that causes offence or distress, even if alcohol was involved. A simple reminder that everyone remains accountable for their conduct can go a long way toward setting the right tone before the festivities begin.

Pre-party checklist for HR and managers:

1. Remind staff of conduct expectations – re-circulate your dignity at work and social media policies.

2. Brief managers – they set the tone; ensure they know their responsibilities (and when to call it a night).

3. Consider inclusion – think about those who don’t drink, celebrate differently, or prefer not to attend.

4. Plan for safety – alcohol, travel home, accessibility, and safeguarding all fall within your duty of care.

5. Follow up wisely – if issues arise, address them promptly and consistently.

A well-managed Christmas event builds culture and connection. But neglecting to manage risk properly can undo both in a single night.   A little preparation now can save you a long January.
