Walmart wants associates, not gig workers, to deliver more orders as the retailer struggles to verify the identity of its Spark drivers

• Walmart is trying to get store workers to deliver more of its online orders, CEO Doug McMillon said.
• It could signal a shift after Walmart spent years recruiting gig workers for its Spark Driver service.
• The retailer is growing its own delivery business after Walmart ended a partnership with DoorDash last year.

Walmart has attracted hundreds of thousands of gig workers to make deliveries through its Spark Driver app. But now, it's trying to get store associates to make more deliveries themselves.
