IT News claims employees are spending about a fifth of their work shift on personal activities - with the Internet being the biggest time waster.
Patricia Wallace, author of the 2004 book "The Internet in the Workplace: How New Technology Is Transforming Work", said employees have always found ways to avoid working too hard.
"The issue is now you have something that seems to be genuinely irresistible because it's such a gateway to the whole planet that's right there on your desk and easily concealed to people passing by," said Wallace, a professor at Johns Hopkins University in Baltimore.
Employees who cyberslack have been shown to spend most of their time emailing, and almost a third of their messages were not related to work, said James Philips, a psychology professor at Australia's Monash University.
Many workers manage finances or shop online. Popular social networking sites such as Facebook and MySpace are also common cyberslacking destinations. It is not uncommon to see a user write on his "status" report that he or she is "at work"..
