A longtime Walmart greeter who has cerebral palsy is afraid he’ll be out of work after store officials changed his job description to add tasks that he’s physically unable to do. Adam Catlin uses a walker and is legally blind. He says he was told by store management in Pennsylvania that he needs to be able to lift 25 pounds (11 kilograms), stand for long periods and read receipts. Walmart calls Catlin a “valued member of the team” and says it’s looking for a way to keep him on.
