Much like my previous post, this sort of technology represents a double edged sword. Technology that provides employers the ability to track employee productivity seems, at a general level, to be both fair and sensible.  The benefits in terms of the ability to identify and remedy inefficiencies, as well as determine poor performers, are clear. 

With that said, the question of intrusiveness cannot be ignored.  Provided with the means to observe an employee's every movement, it is not difficult to imagine a tyrannical manger or boss using such tools to browbeat employees for the smallest of infractions or drops in efficiency.  Should a boss have the ability to monitor one's every movement at the office?  If an employee is sick or in the midst of a family crisis, thus driving a drop in performance, what's to say the kind of manager who takes a single instance over a trend won't utilize such tools to force employees into a kind of constant state of fear?
