Bloomberg – Walmart and other companies are testing a monitoring device for workplace safety made by a startup called StrongArm. “..StrongArm says it has about 30 clients, including Heineken NV and Toyota Motor Corp., and is also establishing relationships with insurance companies interested in ways to reduce workers compensation costs. Walmart says it’s testing StrongArm in eight distribution centers and adds it has no plans to use them in stores. StrongArm says about 15,000 workers have worn its devices, and most of them use it daily. The Brooklyn, New York-based startup expects to have 35,000 daily active users by the end of next year. StrongArm acknowledges that concerns about workplace surveillance surround its work, but the company says its products are designed solely to improve safety and cites a recent study it commissioned that found users wearing them suffered 20% to 50% fewer injuries. It says it’s not tracking individual productivity and that its products aren’t used to punish individual workers or to contest workers compensation claims…”
