You know that some employees cruise the Web at work. But did you know that many sites actively encourage it and even give users ways to deceive their bosses? Sites such as www.ishouldbeworking. com and www.boredatwork.com offer games, jokes and links to help people fritter away the day (plus a countdown-to-the-weekend clock). Some sites include a "panic button" that lets users jump to a more business-like Web page when the boss walks by. The lesson: Urgeto invest in software that allows the organization to track employees' cyberspace travels.
