Bloomberg:

The Boston Consulting Group has outfitted about 100 volunteer employees in its new Manhattan office with badges that embed a microphone and a location sensor. Made by Humanyze in Boston, the badges track physical and verbal interactions. BCG says it intends to use the data to see how office design affects employee communication. Outside critics have called the plan Orwellian and despotic—“It is a little bit invasive,” says Ross Love, 57, a BCG managing partner who volunteered—but the data collected is anonymized, and the company has pledged not to use it for performance evaluation.

Sure, you say that now. But once those badges are in place, once they become the new normal, all bets are off.
