This is a simply ridiculous response. Geolocation is the least intrusive data that is being discussed here. By far the bigger offense is tracking an individual's health to ensure that the employee is sufficiently "healthy."

John Hancock may not be monitoring my location (although every mobile device already is) but by its own admission, it will be monitoring my activity levels, computing the number of steps I take (or whatever other health metric it plans to use e.g. heart rate) and applying some formula to penalize employees who are "underperforming" on their health "goals." Insurance is already an enormously intrusive industry and fitness tracking crosses the threshold of unacceptable conduct.
