Like animal sacrifice, worker surveillance is a lever the manager can pull to feel and appear in control. Okay that's a little harsh. It's more like drilling into someone's skull: it might work, but probably not the reasons you think ("to excise the evil spirits!") and there are almost certainly less harmful, more effective techniques you just don't know about yet. When we can reliably break Goodhart's Law (metrics that are targets aren't good metrics) maybe we'll outgrow our primitive hiring and performance rituals. Speaking of, since the metric is now "moves around the building," do security guards and custodians ever carry the other's trackers for a while? Perhaps there are "custodial red teams" with orders to dirty or disable something and see how long it takes to be restored.
