While a number of posts on this blog have been dedicated to calling in to question the claims of contemporary management theory to enable managers to predict the future, there can be no doubt that much of it is dedicated to controlling employees.
Perhaps the most egregious example of keeping employees under surveillance is used by Amazon, where picker-packers are tagged as they run round hangar-like warehouses, much as convicted offenders on home leave are tagged. The tags are connected to GPS systems which monitor the employees’ walking speed as well as their location. This ensures that they are all working at a trot and don’t take too many toilet breaks.
