According to a new study this week from financial services firm Cornerstone Capital Group, between 6 million and 7.5 million retail jobs are at risk of being replaced over the course of the next 10 years by some form of automation. "That represents at least 38% of the current retail work force, which consists of 16 million workers," reports CNN. "Retail could actually lose a greater proportion of jobs to automation than manufacturing has, according to the study." From the report: That doesn't mean that robots will be roving the aisles of your local department store chatting with customers. Instead, expect to see more automated checkout lines instead of cashiers. This shift alone will likely eliminate millions of jobs. "Cashiers are considered one of the most easily automatable jobs in the economy," said the report. And these job losses will hit women particularly hard, since about 73% of cashiers are women. There will also be fewer sales jobs, as more and more consumers use in-store smartphones and touchscreen computers to find what they need, said John Wilson, head of research at Cornerstone. There will still be some sales people on the floor, but just not as many of them. Rising wages are also helping to drive automation, as state and city governments hike their minimum wages. Additionally, several major retailers including Walmart, the nation's largest employer, have increased wages in order to find and retain the workers they need. The increased competition from e-commerce is also a factor, since it requires retailers to be as efficient as possible in order to compete.
