One in four employees regret Christmas party behaviour

December marks the return of work Christmas celebrations, but for one in four employees it also marks the return of post-party regret, or to some, ‘hangxiety’.

New research from Slater and Gordon reveals 25 per cent of UK workers have regretted what they have said or done during a work Christmas party, highlighting how excessive drinking, workplace gossip and inappropriate behaviour can turn festive fun into a headache for many.

Alcohol appears to be a significant factor in these regrets, where one in five people admitted to drinking a heavy amount at work parties, which is then a key factor for poor decisions and misbehaviour.

The survey of 2,000 UK workers reveals the inappropriate behaviours that people admit to, giving an insight into what exactly causes the post-party regret. Nearly a quarter admitted to discussing office gossip during work Christmas parties, whilst 18 per cent confessed to flirting with colleagues and 13 per cent discussing pay rises.

However, a more serious concern unveiled in the survey found one in ten respondents had admitted to making jokes based on age, race and sexual orientation, and a further eight per cent admitted to conduct of a sexual nature; despite more than half of respondents considering both as inappropriate behaviour.

Despite more than 30 per cent of people incorrectly believing that workplace conduct does not apply at Christmas parties, Slater and Gordon warns this is a misconception - and failure to behave in a proper way can lead to serious consequences.

With 40 years of experience in employment law, Peter Byrne, Head of Employment at Slater and Gordon, believes that the survey has a clear message to remind employees during work festive celebrations.

“Work Christmas parties are a great opportunity to celebrate the past year with colleagues, but it is important to remember that there are still policies that do apply in these environments, despite misconceptions,” says Peter.

“It is the responsibility of all colleagues to enjoy the festivities responsibly. Excessive drinking can be a factor in this, where a few drinks can lead to comments or actions that can have a lasting negative impact on others. Harmless fun can ultimately damage professional relationships and your reputation.

“There is still a workplace requirement to be careful about what you say or do during work Christmas parties, and any form of misconduct can lead to disciplinary action, or even dismissal.”
