Feel like someone's watching? You're probably right

Almost every worker has done it: gotten in a little Facebook updating, personal e-mailing, YouTube watching and friend calling while on the clock. Such indiscretions often went undetected by company management everywhere but the most secure and highly proprietary companies or governmental agencies. Not anymore.

Firms have become sharp-eyed, keenly eared watchdogs as they try to squeeze every penny's worth of their employees' salaries and to ensure they have the most professional and lawsuit-proof workplaces.

Managers use technological advances to capture workers' computer keystrokes, monitor the Web sites they frequent, even track their whereabouts through GPS-enabled cell phones. Some companies have gone as far as using Web cams and minuscule video cameras to secretly record employees' movements.
