The National Retail Federation (NRF) informs it has urged maritime management and the union representing dockworkers along the U.S. West Coast ports to expedite pending contract negotiations and reach agreement on a new deal well in advance of the expiration of the current contract this summer. NRF believes expedited negotiations would strengthen the supply chain and provide shippers and retailers the certainty they need to utilize the West Coast ports during the holiday shipping period, which begins in July.
