An anonymous reader writes For better or worse, surveillance technology is becoming more common in the workplace. These tools are being used to measure and monitor employees, with the promise changing how people work. "Through these new means, companies have found, for example, that workers are more productive if they have more social interaction. So a bank's call center introduced a shared 15-minute coffee break, and a pharmaceutical company replaced coffee makers used by a few marketing workers with a larger cafe area. The result? Increased sales and less turnover." Of course, this kind of monitoring raises privacy concerns. "Whether this kind of monitoring is effective or not, it's a concern," said Lee Tien, a senior staff lawyer at the Electronic Frontier Foundation in San Francisco.
