From InfoWorld:
Employees are using the Web more and more for personal reasons and that is setting U.S. companies back $178 billion annually, a cost of $5,000 per employee, said a study released Tuesday by Websense, Inc.
The San Diego-based Internet management company reported that 50 percent of the surveyed workers admitted to using the Internet for personal purposes at work. Therefore, about 34 million of the 68 million total U.S. employees who use the Internet at work are surfing the Web recreationally on company time, making Internet usage one of the biggest threats to employee productivity.
