Can UPS keep up with Amazon on wages and workers? - Louisville Business First Amazon.com Inc. just took a huge step toward attracting more workers to its operations. The e-commerce retailer announced it is raising its minimum wage to $15 per hour for all for full-time, part-time, temporary (including those hired by agencies) and seasonal employees across the U.S. The change is effective Nov. 1. This is likely huge news for the already-tight Louisville labor market, where Amazon, United Parcel Service Inc., Radial Inc., and other distribution and warehousing operations vie for the same type of worker. Amazon has three distribution centers locally — two in Shepherdsville, Ky., and one in Jeffersonville, Ind. — and about 6,500 employees. UPS has its large Worldport shipping hub, Supply Chain Solutions and significant ground operations in Louisville, and employs about 21,000.
