Dive Brief: Some Starbucks supply chain partners have "struggled" getting deliveries from distribution centers to stores due to labor shortages, the coffee chain's CEO Kevin Johnson said on a Q2 earnings call Tuesday. Starbucks is working with its partners on labor-shortage issues, but said it is not currently a widespread problem. "I do anticipate we'll do a little bit more to invest and help our supply chain partners, whether it's staff that they need in manufacturing or staffing they need for distribution and transportation," Johnson said. The distribution issue comes after Starbucks announced plans last year to increase store throughput by "rapidly transforming" store layouts to add Starbucks Pickup and drive-thrus to meet "shifting consumer behaviors."
