Before you read any more, reach under your desk. Feel around for a black box that wasn't there the last time you had to retrieve a pen under there.
Employers are increasingly monitoring what you're up to at work. They're paying you, so they're using technology to keep tabs on what you're up to, or not.
For instance, last fall Microsoft bought a company called VoloMetrix that logs your computer activity at work. So, your boss can see when you're playing solitaire as opposed to, say, working.
There's also a monitor that bosses are putting under their employees' desks, including recently underneath the desks of journalists at the UK's Daily Telegraph. They found OccupEye monitors that are intended to help companies become more efficient when it comes to office space.
An OccupEye Network Receiver (second photo) can track up to 511 OccupEye sensors (first photo). The company suggests a typical scenario with one receiver on each floor of an office building, and monitors under each desk.
