ATLANTA (AP) - The head of UPS Inc.'s U.S. package operations is calling it quits.
Jim Winestock has been with the Atlanta-based company 40 years. He will retire in February.
UPS announced Tuesday that Myron Gray will replace Winestock. Gray currently oversees regional operations in Canada and all of Latin America.
Winestock, who is 57, joined UPS in 1969 as a part-time package loader in northern Florida while in college. He rose through the ranks and was named to his current post at UPS, also known as United Parcel Service, in 2004.
Gray joined UPS in 1978 as a part-time package handler while attending the University of Memphis. He assumed command of UPS' Americas region in January 2008.
UPS is the world's largest shipping carrier.
