EMPLOYERS could find themselves powerless to act if workers phone in sick the day after an office Christmas party – and could even be liable for bad behaviour – unless stringent guidelines are in place first, a North-East law firm warned last night.

As the countdown to Christmas party season starts, employers are being warned of the perils of failing to protect themselves and lay down strict rules to staff as to how they are expected to behave.

James Wilders, employment law partner at Newcastle-based Dickinson Dees, warned that companies could face sizeable compensation claims if they do not take adequate action before a staff party.

Mr Wilders advised that companies have no comeback against issues such as workers being too hungover to come to work the following day, unless it is made clear what is expected.

“Employers often find themselves experiencing a costly hangover when employees’ behaviour at parties gets out of hand. Many don’t realise they are legally responsible for the behaviour of their employees in a working environment, and this includes the Christmas party,” he said.

“However, it is relatively straightforward for employers to protect themselves – for instance they should issue clear guidelines to staff outlining expectations in behaviour before the event.

“Because of the wide-ranging employment rights laws, whose number and scope increases every year, liability can arise in an increasing number of ways.

“For instance, unwelcome advances by someone towards a colleague could lead to a sexual harassment claim.”

Mr Wilders has some advice for employers about how to tackle potential pitfalls of a staff party.

He said: “Christmas parties invariably involve lots of alcohol, but it does increase the risk of aggressive behaviour. Employers need to have a plan to deal with a situation should it get out of hand.

“Make it clear well in advance that all employees are expected at work the next day, and consider how long the bar stays open.

“If you let people drink until 1am, you only have yourself to blame if most don’t show up the next day.”
