Ramesh Shrestha doesn’t worry about a robot replacing his job because in some ways — one already has. Shrestha, a supervisor for commercial cleaning company Ultra Shine, has a robot named Bob as a coworker at the Westmount Centre shopping mall in Edmonton. Bob robotically swivels around the mall’s food court and stops for curious shoppers as he scrubs the floors every day. Unlike the humans who used to do this job, Bob never tires or suffers from back pain. The robot has not replaced any of Ultra Shine’s employees. The company actually has been expanding, and data from Statistics Canada shows a similar story has been playing out for years at other businesses across the country.
