Our senior partner, Graham Davies, said it was crucial that employers reviewed their email and internet policies regularly.
"With technology moving at such an incredible pace, any policies you put in place may well be out of date in a very short time. So it's vital that every company looks closely at its procedures frequently in order to stay one step ahead."
Graham said in particular, policies on social networking and video sharing websites needed to be tightened up given the increasing interest in sites such as Facebook, twitter and LinkedIn.
"You may decide to ban your staff from posting anything about the work they do for your company or anything that could identify it, because you don't want internal discussions or decisions spread all over the internet. And don't allow workers to provide links to your company's website because you don't want to give the impression that you're officially linked to what they may have written in a personal capacity.
"It's also important to stress to employees that they must clearly state that any views they express are their own, and not your corporate opinion.
"Technology is changing the face of communication in all areas of our lives today, and it's up to you to ensure your staff don't damage your company's reputation with ill-considered messages and personal opinions."
