Call Buttons to replace staffing of departments.
Walmart is even using digital technology to change the way customers ask for help. New next-gen call buttons activate GPS-enabled devices worn by staff members, meaning, only employees who have training in the appropriate department will be called to that department when that button is pressed.
This prevents customers having to wander around the store looking for a random staff member, only to be told they aren’t trained in that department and the customer will have to wait while they go find someone who is. Customers can instead simply press the button and wait while the correct person comes to them.
