Computers, BlackBerries, the Internet and other fun high-tech toys were supposed to make it easier and more efficient for employees to get the job done, right? But AUDREY MROSS, who heads the labor and employment practice at Dallas' Munck Butrus Carter, P.C., reports what most of us already know to be true. Those same `productivity enhancers' have made it much easier for people to waste time surfing the Web, sending instant-messages to friends and doing other things on the job that don't contribute to the bottom line. "There even are virtual bubble wrap sites where people can go and pop bubbles online," says Mross, who recently spoke about the issue at a Texas Association of Business gathering on worker productivity, litigation and individual privacy.
