Most people who strap a fitness tracker to their wrist do so for motivation toward a daily step goal, or perhaps to prove their suspicions about a bad night's sleep. They don't necessarily think about ways it can help their employers help them. But that's why, in 2019, a pilot group of PwC employees in the UK began wearing devices connected to their work calendars.

 

This way, the firm could receive anonymized data that linked, for example, stress levels to meeting sprawl. "The frontier of wearables is the world of work," said Pete Brown, the joint global leader of people and organization, PwC UK. These ubiquitous, sensor-powered devices, he added, "have the potential to unlock a new world of insight for people and employees, supporting employee engagement and wellness."
