( MENAFN - IANS) New York, May 6 (IANS) Jobs for thousands of letter and package delivery workers at the US Postal Service (USPS) and United Parcel Service (UPS) could be cut this year, with both looking to slash costs and streamline operations as the effects of US President Donald Trump's tariffs and digital innovation ripple through the economy, the Los Angeles Times reported. Last week, the chief executive of UPS announced that the company will cut 20,000 jobs this year, or about 4 per cent of its global workforce, and plans to close 73 distribution facilities by the end of June, Xinhua news agency reported. The closures are part of a long-term plan to modernise the operations of distribution centers, including adding automation, either fully or in part, to 400 of its facilities. Earlier this year, UPS announced that it had reached a deal with Amazon, its largest customer, to reduce business-related operations by more than 50 per cent by the second half of 2026.
